crankshaft position sensor
 

OK. I have an OBD1 Trouble Code 36 (24X Signal Circuit Error) - Faulty Circuit error from coil packs to module. The manual says to test the coils and ignition module. They say before i check the manual i should check the Crankshaft position sensors functionality. Here are the symptoms.

I will go out and start the car from a cold start. I will drive it around for a little and then go into a store or something and come out to start it and it cranks but wont start. Eventually I can get it to start. So my guess is that the CPS is heating up and not functioning correctly. Does this sound right?

Car is a 1995 3.4 V6. I have been reading around about the Distributor-Less Ignition System. My understanding is that the CPS sends a signal to the ignition module which adjusts the timing, etc. Is this correct? So if the CPS was bad it would cause a problem like this? My idle is pretty rough and the car is running rich.

sounds like you are on the right track, either that or the module itself..

i would hope its not the module they are much more expensive :(

When the CPS died on my 3.1 v6 the car wouldn't start at all.

well i am almost positive this is the problem... i just recalled that less than a year ago it was replaced for the code 36 and the car was still running then... it is still running now but throwing code 36 again. i am going to call the mechanic who put it in and see if there is any type of warranty on it

somehow it was the EGR that was bad... replaced it and the car runs better than it ever has
