Auto Diagnose : During car starting the car initially starts then after a while it suddenly stops, there are a lot of possible reasons. Let's find out by doing a simple test.

(1) Start the engine,
from neutral position depressed the acceleration pedal.

(2) While your foot is in the accelerator pedal, observe if the car engine will continuously running. If the car engine stays running while you depressed the acceleration pedal then the problem is the choke. By keeping pressure on the accelerator, you keep the choke in a position that keeps the engine running thus the engine will not stop.

If the engine will not continuously run even when the accelerator pedal is depressed means the problem is not the choke then continue the car problem diagnosis.

(3) If the car problems occur only when the weather is cold then the problem is that the choke is stuck in open position. As you may not aware of, if the engine is cold the choke should be in the closed position so that the air/fuel mixture will become rich as a requirement to start a cold engine. In this case the engine is cold but the air/fuel mixture is too lean, meaning too much air and not enough fuel, this is because the choke is open thus your car engine will not stay running.

(4) If the car problems occur even when the engine is not cold then the problem is a clogged fuel filter or a bad fuel pump.
A bad fuel pump will not be able to provide a steady amount of fuel which causes the car engine not to stay running. Also, a clogged fuel filter will prevent the flow of fuel.

Possible shorted transmission harness or transmission shift solenoids. Disconnect the big connector at the transmission under the car and see if the short stops and fuses don't go.

Hi Arnulfo:
How long does it run before it stops?
Sounds to me like a possible fuel delivery problem.
Is there a fuel filter and if so, have you changed it?

Would an alternator make your car will not start

If your battery is fully charged, the car can start and run from the battery with no alternator at all. It might run 1/2 hr with no alternator.

A good test for the alternator is to start the car and then unhook one of the battery terminals. If the alternator is good, the car will keep on running without the battery. If the car turns off hen you disconnect a terminal, then the alternator isn't working.

But a bad alternator won't stop your car from will just not keep your battery charged or keep the motor running once the battery gets less than 12V

Runs for a short time and stops wat for 5mins. and strates up runs and stops

Sounds like it is starving for fuel or air. Let's check it out remove air cleaner when was it changed last? Check it is it dirty? Change it now try starting the car again. Did it run for a longer time? If so all it needed was an air filter. If it sills stalls Start it and let it run and when its about to cut off I want you to spray it with starting fluid and try to keep it running. If this keeps it from stalling you need a new gas filter. So change it and start your car it should run now. My advice to you is keep your car tuned up and change all filters.

If you still have an issue after all this we have to look else where. Let me know how you make out.

Car hessitates

Check coolant temp sensor if car runs okay after first start up. If it does not run OK after getting engine warm, probably idle air control valve.

The fan motors keeps running after car is shut off. Also sometimes fans start when car is started cold.

If the fans didn't run any further the engine continues to warm and possible seizure will occur. This is also the reason you will probably go through batteries in the long run. Hopefully this helps the issue you are having.
