Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hi, have you checked for fuel pressure yet?
Ok, what engine is in your ram so I can give you the correct wire colors to test?
Ok, at any injector or coil check for power at the dark green/orange wire when you first turn the key to run. It should get hot for about 2 seconds when you first turn the key to run.
Ok, is it still flagging a code for the crank sensor? That last test shows ASD is coming on, then it has to see RPM from the crank sensor to stay on.
With the key in run, do you have 5 volts at the orange wire of the crank position sensor? The violet/white is the 5 volt supply to the cam position sensor, check that also please.
Does your scanner show the cam and crank signals? It would be even better if you have a lab scope. that's the best way to check a crank signal.
But your scanner does have a PID for them I'm asking and they both show no signal?
You can get scopes fairly cheap now if you don't have one. This way you could see if the 5 volt square wave is getting to the pcm.
Ok, does your pcm have 3 or 4 connectors? That's a borderline year for JTEC vs. NGC.
Ok, the 2nd connector from the left, pin 34 is the cam signal and 35 is the crank signal. When you scope those 2 pins, you should see a steady 5 volt square wave pattern when the engine is cranking.
ok sounds good
