Do here is my question 2002chrysler PT....2.4l....crank bit no start has Spark and will run on propane....all pins have power at the asd and fuel pump relay and ,8v...refrence ...at the cam and crank....however no ground ,at the fuel pump relay ......someone suggest a lazy cam or crank sensor....however wouldnt that kick a code and an intermitant ground problem.....please realize i'm working with an ohmeter a test light and a simple scan tool...thank you in advance
to rule out a crank or cam sensor issue on this, you absolutely will get a 1-2 second prime of the fuel pump/ASD relay circuits when the key is first turned on. If you get this "prime" (power to the ignition coils, fuel injectors, fuel pump, O2 heater, alternator) during initial key on, but then no power during cranking, the I agree, you have an input problem (cam/crank sensor). If you have no "prime" power and no power cranking, forget about the cam/crank sensors, that is not your problem
