Starter circuit problem and will not crank. 2000 GMC Savana 2500

My van is having a starter circuit problem. While I was filling the tank at a gas station, my van would not start. I had to push it away from the pumps and it then started. When I got home and turned it off, it would not restart. I have checked the battery and failed load test and replaced, but no change. I then followed the circuit to PnP switch but no signal through in park; bypassed to verify and replaced the switch. I found a bad starter relay and replaced it. Still no change. Then, I checked the starter signal and I do now have a signal but the van still will not crank. I removed the star
Experienced mechanics share their insights in answering this question :
It sounds like the main battery lead to the starter is not suppling enough power to turn the starter. The way to test this is to use a multimeter and check the power cable (red one) with meter set to 20 volt scale. The red meter lead on the battery positive post and negative lead on the big cable connection on the starter. Try to crank the engine and you should not see more than .2 volts or 2/10 of a volt on the meter. If you do, then the cable is bad.

If the test is okay, then do the same with the negative cable from the battery negative terminal to the engine ground. If either test shows more than 2/10 of a volt, then the cable is bad and needs to be replaced or have the connection cleaned. Most of the time it is the connections at the battery to the cable. This test is called a voltage drop test.

If you need help having this checked, a qualified professional, like one from YourMechanic, can come to your car’s location to diagnose the starting problem and assist you with repairs.

The most common reasons a GMC Savana 2500 won`t start are a dead battery, an alternator problem, or failed starter.
The most common reasons a GMC Savana 3500 won`t start are a dead battery, an alternator problem, or failed starter.
A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.
1 Start motor engages but the engine doesn`t turn

The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.

The most common reasons a Chevrolet Silverado 2500 HD won`t start are a dead battery, an alternator problem, or failed starter.
Battery issues, including the battery being dead or the terminals getting corroded, are the most common cause of this issue, and the first thing most mechanics will look at. Blown fuses and relays can cause this problem, too.
The starter solenoid is an electromagnetic switch that engages the starter motor. How can I tell if my starter solenoid is bad? If you`re having trouble cranking the engine over but the battery is charged, or if your starter won`t disengage after starting the engine, it`s likely a starter solenoid issue.
Bad Sensors

One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.

One of the best ways to determine if a car fuse has blown is by using a test light. It should illuminate both ends of the fuse, and, if it doesn`t, it needs to be replaced. Sometimes, a blown fuse is caused by a damaged wire, motor, or other part.
The cause of this problem is usually one of 3 things – a failed starter motor, a bad connection between the battery and starter motor, or a blown fuse (if present) in line between the starter and the battery.
The most common reason a Chevy car (or any car) won`t start is a dead battery. If you have a battery tester, check your charge to see if it`s low. A dead battery can also be jumpstarted with jumper cables.
OnStar Remote Start is limited to two instances per ignition cycle.
The most common reasons a GMC Sierra 1500 won`t start are a dead battery, an alternator problem, or failed starter.
If your car won`t start, but your battery is fine, chances are you have a bad alternator. This is another charging system issue, like a dead battery, that won`t let you start your car.
The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
Starter motors should make noise when you turn your ignition key fully to activate your car. If you turn the key and do not hear anything, there`s a chance that there`s something wrong with the vehicle`s ignition switch.
To check the voltage reaching the starter, connect the voltmeter to the starter feed terminal and earth it on the starter casing. Test the voltage reaching the starter. For a negative-earth system on a car with a pre-engaged starter, connect the positive lead of the voltmeter to the feed terminal on the solenoid.
If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won`t turn over – no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.
When you switch on the ignition key, a starter relay transmits small electric power to the starter solenoid, while the solenoid pulls a big current straight from the car batteries. This activates the solenoid, which sends electricity to the starter motor, which spins the flywheel.
Push Start Your Manual Transmission Vehicle

Put it in second gear, then have two or three strong friends push your vehicle. The idea is to get the car rolling at a fairly good clip, then release the clutch while still turning the key. Do it right and your car should start, despite your faulty starter motor.

A car`s engine won`t start if you jump-start it with a damaged starter motor. Jump-starting just increases the power of the battery. An auto transmission automobile cannot be pushed or towed started. However, a manual transmission car with a broken starter may.
Solenoid coil failure can be caused by a number of factors. Applying an incorrect voltage to the coil will cause it to fail and may cause the coil to burn out. Electrical surges or spikes may also damage the coil. Burnt out coils cannot be repaired and will need to be replaced.
The starter circuit connects the battery to the starter motor. The solenoid acts as the on/off switch for the starter motor circuit — controlling the burst of electrical current from the battery. The solenoid itself is controlled by a control circuit, which links it to the ignition switch.

Starter circuit problem and will not crank. 2000 GMC Savana 2500
ANSWER : It sounds like the main battery lead to the starter is not suppling enough power to turn the starter.

no crank with new starter, starter relay, battery, alternater.
ANSWER : If you tried jumping the contacts on the starter directly, then your problem is most likely a power or ground issue. The battery ground cable may not be making a good connection at the engine ground, or there could be a problem in the positive or negative battery cables making them unable to properly complete the circuit. I would start by checking the resistance from the engine ground to the battery ground, and from starter positive to the battery positive terminal. Also do a voltage drop test across each of the cables, which will help determine if there is a problem with them. If after checking the cables and connections, the car still doesn’t start, then you should have a qualified professional, such as one from YourMechanic, diagnose the problem for you.

its cranks slow, sometimes it cranks fine and other times i have to crank it twice, it happens randomly
ANSWER : A slow cranking condition is caused by not getting enough power to the starter. Since you replaced the starter then you may have a weak or borderline bad battery. One of your cables may be bad causing the slow crank condition.

If the battery is weak then you may get the problem one time and a sudden burst the next. If you battery is more than a couple years old I’d suggest having it load tested to see if it is bad or if is a cable problem.

Do not rule out the starter even if the problem was fixed for a while after the starter was replaced. I’d suggest getting your vehicle inspected by a qualified professional, such as one from YourMechanic, to diagnose your starting issue and repair it as necessary. Good luck.

When I turn my key over my car won’t crank but my lights on my dash will come on. I had my starter teststed and it was fine.
ANSWER : Hi there. First off – what you did with the hooking up a flip switch is not recommended; so please remove that as soon as possible to reduce the possibility of having a serious electrical fire or overload. Second, if you turn the key and it does not crank over, it’s likely the ignition cylinder or ignition relay that is faulty. If the flip switch worked, then the issue is likely the ignition relay. I would start with replacing the ignition relay or have a professional mobile mechanic come to your location and complete a car is hard to start inspection to determine the exact source of this issue and complete the right repairs.

The starter off and on wont turn over when trying to crank the car.
ANSWER : Hello, thank you for writing in. Often when starters are installed they come with a shim. These shims need to be installed to help hold the starter at the proper angle. If the angle is off the gears may not mesh correctly putting excess pressure on it that the starter cannot compete with. If the starter did not come with a shim, or you do not have it anymore, you can likely purchase or fabricate one relatively easily. If this does not solve the issue, make sure there are no wires that are being pinched or shorted out when the full weight of the car is being supported.

Car will not crank after putting in a new starter. Forced starter to start up and engine starts but stalls out. Will the security continue to cut off fuel while force starting?
ANSWER : Hi there. Forcing the starter to engage to make the engine run without the ignition engaging the starter will continue to keep the security on. This is a safety feature that keeps people from stealing your vehicle. I recommend replacing the ignition switch and checking the wires to make sure that they are all tight and clean. If you need further assistance with diagnosing your ignition problem, then seek out a professional, such as one from Your Mechanic, to help you.

Caliber turns over but won’t start?
ANSWER : Hi there. Assuming, you have reinstalled the original PCM (powertrain control module) and still won’t start, circuit tests for the crankshaft position sensor need to be performed. A poor connection or broken wire could be the cause for the no start condition. It could also be the PCM is at fault and the replacement does require programming. There are other possibilities for a no start condition, a faulty PCM relay, a faulty ASD (automatic shutdown) relay, fuel related issues and ignition system issues. I recommend having your vehicle’s no start be diagnosed and repaired by a certified technician, such as one from YourMechanic.

Problems starting my car. It cranks strong but for a long time – 2012 Chevrolet Silverado 1500
ANSWER : Hi there. A malfunctioning mass air flow sensor may create the extended crank concern; however, a sticking idle air control valve can create the same concern. Cleaning of either components has been known to help with the situation. However, this is rarely a long term repair and is only temporary.

You could clean one at a time and see which one alleviates the extended crank and replace as necessary. Also, there may be a residual fuel pressure problem. Residual fuel pressure is the pressure that remains in the fuel lines and injectors to provide immediate start up fuel. If the check valve in the fuel system is bleeding off, this could definitely be the cause. However, since it is only 10% of the time, it may be difficult to verify.

I recommend having a certified technician, such as one from YourMechanic, assist you with an idle speed inspection to determine if a mass air flow sensor replacement or idle air control valve replacement may be necessary.
