Hi All,
Have a problem here. 1994 Chrysler T&C. I think it has either a bad crank sensor or a bad cam sensor, but I can't figure out which one it is.
The car runs fine until whicher sensor it is decides to stop working. Then the entire engine just stops. Attempting to start gets no attempt to fire. I know it's getting fuel because a guage on the fuel rail connected when it's not starting shows around 41/42psi. I know it's not a jumped timing chain because when it is running it's smooth at all speed ranges. I'm pretty sure it's not the coil because all plugs are affected. When it won't start, it's not getting spark, I checked that.
I think it's heat related because if I let the engine sit for 10-20 minutes it will start up again.
It just started doing this today. Fortunately it didn't do it when driving down the highway or anything like that. This evening I let it idle after getting home and after about 15 minutes of idling it stopped. Trying to restart it, no-go. Temp guage for coolant does not show overheating. The CEL is -not- set. I haven't pulled engine codes yet to see if there are any.
There is a procedure in the FSM for determining which sensor it is, but that would mean letting it idle tomorrow probably for about a half hour, and hope that it dies. But I never know when it is going to start so the test results could be screwed. And I could let it idle for a lot longer but it could possibly not die.
