Won’t start

After replacing tension pulley and serpentine belt still no fire. Turns over fine and acts like wants to crank but like no fuel getting to engine. All fluids appear OK no previous problems driving. Could this be a fuel pump problem or is there some kind of theft system keeping from starting after being jumped after new belt replacement!!!

My car has 150000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there. One thing that even professional mechanics tend to forget is double checking all electrical connections to sensors and engine monitors that might have been disconnected during the serpentine belt and pulley change. In most cases, it’s the crankshaft or cam position sensor that is disconnected during the process that is not reconnected and causes this problem. The first thing I’d do is just verify everything is connected the way it should. If all checks out, you might want to download any stored error codes in the ECU or have a professional mechanic complete a car is hard to start inspection to help you resolve this issue.

Vehicle won’t start, once it’s jump started it only stays running until you turn it off, then it work start again without jumping.
ANSWER : Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

ANSWER : Hi there. This does sound like an issue with the wiring. If the check engine light is coming on every now and then this means that when it does not come on there is no power to the computer. This can be the wiring harness issue or an ignition switch problem. I would have to test for voltage to the computer when the problem is occurring to be able to find where the issue lies. If you need assistance, a certified YourMechanic technician can be dispatched to your location to inspect your vehicle’s non-start issue and suggest any necessary repairs.

Car won’t start. When trying to start, starter makes a clicking noise and then closed back hatch recloses.
ANSWER : It sounds like there is some type of drain on the battery. When there is low voltage in a battery, it can cause several symptoms. The electrical systems can act very strangely when they don’t have the correct voltage being supplied. When a battery won’t hold a charge, it can be caused by a wiring issue, a bad battery, or some type of parasitic draw that can slowly pull voltage from the battery. Some electrical diagnosis done by a professional, such as one from YourMechanic, will be necessary to pinpoint the cause.

ANSWER : Hi there. It sounds like you have a failed starter. However, without proper testing there is no way to be 100% sure. I suggest having the battery tested first with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Also inspect for corrosion on the terminals and cables as this will cause excessive resistance and not allow proper voltage/amps to the starter. Other possible failures could be in the wiring harness, relay, fuses, or communication network. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not start inspection.
