I have a 93 galant with the 4g64, it starts and runs like a champ for a bit but when it gets hot it starts stalling and is undriveable. A little ghetto shop told me it was a 600 dollar crank sensor. Anybody have a cheaper conclusion? thanks in advance

Sorry thats bull**** because if it was the sensor then it would not start in the first place. Im willing to bet that this is a leak of some kind. Most probly a vac leak. Are you leaking any fluids? If none of those are the culprit then my money is on a failing fuel pump. Im willing to bet its a vac leak. Do yourself a favor and dont go back to the ghetto place.

 

thanks I was wondering how the crank sensor could change from heating up. There are no fluids leaking anywhere the car is in great shape. I will check for vacuum leaks now. What is the best way to check for leaks besides listening? maybe i'll just go buy a roll of vacuum line and replace everything couldn't hurt I guess. Any other ideas if not the vacuum lines?

 

Fuel pump failure... that would be my least idea. It makes sence to be a leak of some kind because with heat there is expansion and thats when the hole will really start to open up.

I was about to click the OK button and had a little thought. It is possible that one of your plugs or wires could be not functioning 100% when heated. This is also a likely problem. If you want you can replace them.

 

thanks alot sebba you have been extremely helpful I will post again once I try these things hopefully they work. thanks again

Try the plugs and wires first!

 

I wanted to rephrase the question in case it matters I had said it stalls but I guess that could be taken differently. It just totally dies when it gets hot. does this change anything?

thanks

Nope im still going with a malfunctioning plug or wire.

 

clean your throttle body.

 

That wouldnt be the problem though. Although cleaning it will always help you.
