I have a 1996 Toyota Corolla DX with about 200k miles on it. It runs good for the most part, but recently had a problem where it would not start. Napa tested my alternator, which failed, so I installed a new one. Now the car starts but won't remain running. The battery is also new. What could be the cause? Edit today I've noticed white smoke coming from exhaust as t you car starts to overheat... Not when the engine is cool though, only as the car overheats. The white smoke combined with the over heat along with decreases in my fuel effeciency and acceleration makes me wonder if it's the head gasket
Common things that can shut a car down after starting:
- bad or disconnected idle air control valve (hold the accelerator down after starting, see if it keeps the engine alive)
- bad or disconnected mass airflow sensor
- bad ignition switch
- blocked fuel filter (test your fuel pressure)
- weak fuel pump (test your fuel pressure with the engine off but the key at the 'on' position)
Thanks for taking the time to help me on this issue... Old thread but it needs closure. Turned out to be the head gasket. After noticing little puffs of white smoke coming from exhaust, i decided to run a quick check for a head gasket failure. I removed the cap to my radiator, removed all spark plugs, disconnected fuel relay, and filled my radiator with water to the brim. I then installed a spark plug in cylinder 1, left the rest open (to diagnose exact cylinder, I guess I wanted an idea of where my gasket was blown) and turned the ignition over a few times. If bubbles or any gushing came from radiator cap, I could probably assume a gasket failure. Cylinders 1 & 2 passed but 3 & 4 made water gush out of the radiator. So now I'm waiting on the new gasket and I'm gonna attempt to replace it myself.
