Still seems a lot like a PCM issue......

 

Pulsing doesn't necessarily mean pulsing correctly. The pulse could be delayed or not long enough, resulting in a mis-timed or weak spark, if a spark happens at all. Based on all of your troubleshooting and assuming the wiring is okay, it sounds like you're down to a bad crank sensor or PCM.

 

if it was receiving a bad/faulty signal from the crank sensor isn’t there a pretty good chance it would have set a code or at least acted up before complete/total failure?

 

I would think if it was actually firing the coil, you would at least get a backfire if it wasn't timed properly.

 

There is no code for a bad crank sensor.

 

this is not my area of expertise, this is why I’m asking but I do know for a fact that There are actually several for that circuit. Now maybe they don’t apply to a certain type of sensor failure, but they do exist. for example, I know it’s not a dodge, but when the one in my wife’s Audi failed it set a code for cps signal being out of range.

Not that it matters because I just looked at the signal on a scope and it’s within spec….

P0335 Crankshaft Position Sensor A Circuit Malfunction
P0336 Crankshaft Position Sensor A Circuit Range/Performance
P0337 Crankshaft Position Sensor A Circuit Low Input
P0338 Crankshaft Position Sensor A Circuit High Input
P0339 Crankshaft Position Sensor A Circuit Intermittent

 

Yesterday my buddy let me borrow his scope and it appears cam and crank sensors are putting out proper signal. After conferring with a friend of mine who teaches automotive electronics at the local trade school he said based on the info I provided it does appear to point to a pcm problem. I went ahead and ordered a new pcm this morning. I’ll check back in here with the results thanks for the help!

 

My reman pcm arrived today, plugged it in and it fired right up. Back to running like a champ! Thanks for your help!

 

Awesome.

 

I like good ending
