HELP PLEASE! My car keeps shutting off on my while driving! Sign In

 Hi, I recently started having a problem with my engine shutting down on my 92 lude Si, its got about 220000 miles on the body but the engine was rebuilt due to accident. It first happened a week ago right after I filled up gas, I went to turn the ignition and it just died, not cranking, no sound, just completely shutdown, and the lights wouldn't turn on or anything. As if battery was completely dead. My buddy jumped me and I was good to go. Couple days later, it shut down on my while i was driving, I think I was in second gear slowly accelerating, and I couldn't crank it over for a few minutes. Then it was fine. Then next day same problem, much more frequent, every 10 to 15 minutes it would shut down while driving and the check engine light comes on and shuts off. It would crank but not start until a few times cranking and hitting gas, and once it starts, check engine light dissappears until it shuts down again. Any suggestions? I am going to clean battery terminals, check voltage on the battery, voltage on alternator. Any help would be great! Thanks!

with 220000 miles it could be just about anything.

however, a few a ideas it could be...

keep an eye on the temperature gauge while you are driving. a check engine light could come on if the motor is overheating, and when you turn it off. the computer will use a "safety" and let the car cool down before it allows it to crank again.

even though the check engine light isn't on anymore... if you hook a scan tool up to it now. you can retrieve freeze frame data which will give you the conditions when the code was set. also check the 'pending codes' to see if a computer monitor already saw a screw up but needs to see it again before it sets the code. this can give you a hint about whats going on.

another possibility is that a relay is stuck closed because of wear or high resistance. so when it cools down then it unsticks itself.

these a just a few basic ideas. but it could be many other things

Ok, sorry for taking so long to reply, I have replace my batter terminals because they were badly corroded, and I have gotten my battery and alternator tested at advanced auto parts, and both are fine. Now when the vehicle stalls, the power doesn't shut off, just dies and check engine light comes on and it takes a few cranks with me furiously hitting the gas simultaneously, are these signs of fuel pump to injectors? Yea, I forgot to get the computer read, I gotta try to do that tomorrow.

could be fuel sensors relating to the fuel injection. if they burn out the car thinks its cold and floods the engine with gas, thus causing it to stall. then you have to wait till the engine is cool and gas drips down

would a diagnostic scan be able to tell me if that would be it?
