no crank with new starter, starter relay, battery, alternater.
my car stopped cranking over, so i went out bought a new starter, alternater, battery, and starter relay. once i replaced it all everything went together as the old parts. but when i went to go start it there was no crank. there is juice getting to all the electronics but it still wont crank. even tried jumping it from the starter with a screwdriver connecting both contact points still no crank.
My car has 100000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
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.
How to Identify and Fix Common car Problems ?

If you`ve replaced your battery but the engine still won`t start, it could actually be an engine problem. A seized engine won`t turn over, and that often resembles a bad starter or dead battery. If you suspect that your problem stems from an engine issue, it could take hours to diagnose and repair.
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.
Fortunately (spoiler alert) the root cause of a no-crank is almost always simple. Most of the time it`s simply due to a low or dead battery, or voltage drop through a corroded connection. Rule those out before you suspect the starter itself.
The starter relay makes a clicking sound, but the engine does not rotate, which indicates that the starter motor is not receiving enough current from the relay. This may also be a sign of low or exhausted battery power. Only when it transmits enough current to the starter, the relay starts to work.
The new battery does not have to be configured for the most current car models. Banner conclusion: No registration required; a check of the electrical functions after changing the battery is recommended.
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.
When you have a bad starter solenoid, the starter motor won`t work. This means the engine won`t start when you turn on the starter switch or press the start button. However, if your vehicle has an automatic transmission, the engine could sometimes not crank because of the neutral safety switch.
If the timing belt or chain has broke then you may have bent the valves and the chain or belt will jam up the crankshaft from turning. The pistons will contact the calves and engine will not turn.
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.
A dead battery is the most common cause of a clicking noise when trying to start your car. Usually, you will hear a rapid succession of clicks. The noise indicates that the starter solenoid or relay is operating, but there isn`t enough battery current to turn the starter motor.
If your ECU controls the anti-theft system, disconnecting the battery may lock you out of your car. Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.
Every time the vehicle`s battery is disconnected or discharged, the Steering Angle Neutral Point memorization and the Steering Sensor Zero Point Calibration must be performed.
The Likely Culprit: Starter
If you`re unable to start your vehicle, check and see if the headlights and dash lights come on. If they shine bright and clear, that means that the battery and alternator are likely not the cause of the problem. If they were, there wouldn`t be enough power to run the lights.

I got a F350 Diesel I put a alternator on a new starter a new starter relay and new alternator and the starter stays engaged with
ANSWER : Check the wiring on the starter to the ignition switch and see if they are crossed on the solenoid of the starter. If the wiring is crossed, the starter solenoid will stay engaged as the starter is engaged. If the wiring is hooked up normal, then the ignition switch maybe damaged causing the starter to stay engaged. If you need further assistance with your starter staying engaged, then seek out a professional, such as one from Your Mechanic, to help you.

Just put a new carburetor, battery, starter relay, alternator, car stalls out while driving and battery dies when restarted
ANSWER : The battery should be load tested. Simply charging the battery or measuring voltage is not adequate. Measure charging output, too. You want to confirm that the ignition system, including for instance the ignition coil and ignition switch, are not intermittently cutting out. Coils can fail as temperature rises (resistance increases with temperature) so if you run the car for a while and all of a sudden it quits, measure the resistance of the coil windings to see if that provides a clue. Apart from that, the ENTIRE primary side ignition circuit has to be checked, using voltage drop testing (and testing of the hall effect sensor in the distributor), to rule the primary side in or out. If you want the required diagnostic steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a stalling diagnostic and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Engine won’t crank with a new battery, new starter and new positive battery connection.
ANSWER : Hi there. It is very possible that you have an ignition system component failure that is causing your car not to crank over and start. It could be the ignition relay, starter relay or a faulty ground wire. Before you complete any repairs, I would recommend having a professional mobile mechanic come to your location and complete a car is hard to start inspection first. This will allow them to pinpoint the source of your issue and recommend the right repairs be completed.

I got a new battery new alternator put in but my battery just gets drained I keep having to buy new batterys
ANSWER : This may be a sign of a failing voltage regulator or potentially a bad grounding problem causing a draw on the system. The voltage regulator is a unit that regulates the charging of the battery by the alternator. Often times this will result in the alternator allowing too much power to be delivered to the battery resulting in damaging wires and prematurely sometimes destroying the battery. In other cases it may result in the alternator not supplying enough power to the battery, resulting in undercharging the battery or not charging it at all. In either case, I would recommend having an expert from YourMechanic come to your location to diagnose your vehicle’s charging system.

My car cranks but will not start. I try to do fix the car myself. I put new battery, new alternator, and new ignition coils.
ANSWER : Hi there. Check the spark plugs and see if they are worn or burned. If the plugs are good and they have a good spark, then the engine compression could be low causing a no start situation. If the spark plugs are not emitting a spark, then the crankshaft position sensor could have failed or disconnected. Check the crankshaft position sensor wiring harness and make sure that its plugged in. Check the sensor and make sure that its not broken or damaged. If you need further assistance with your engine not starting, then seek out a professional, such as one from Your Mechanic, to help you.

It cranks doesn’t start new batteries, oil pressure switch new pmd, new injection pump. new alternator, new glow plugs.
ANSWER : Hello.
A crank but no start condition can be caused by many things. A few common causes are a faulty crank position sensor, or issues with the fuel system. The crank position sensor is used in the engine’s fuel calculations, and in some cases it’s failure will disable the engine.
It may also be possible that there is issues with the fuel system that are preventing the engine from running. If the fuel pump or injectors have an issue the engine may not run correctly, or at all. It may also be possible, for either case, that the issue may be wiring related.
I would start by trying to determine if the engine is getting fuel and then going from there. If you need assistance with these checks, consider YourMechanic, as one of our mobile technicians can come to you in order to diagnose your starting issue firsthand for an accurate repair.

i have new battery new battery clamps and cables, new strter cilanoid and no power
ANSWER : Hello, thank you for writing in. If you are not able to get the starter to turn over or make any noise what so ever, then you need to start by checking the power supply to the starter solenoid. If it has a full 12 volt power supply available, then you are having either electrical or mechanical issues with the starter or the new solenoid. It may even need to be shimmed so that the gears are aligning correctly. If you do not have a full 12 volts available at the starter, then you need to trace down the electrical fault. You can start at the battery or the starter, and trace back until you find where the voltage from the battery drops off. There in lies your problem. For more help with this testing, contact our service department to schedule an appointment.
