Re: DTC PO351
I tried 2 different stores and neither had a fuel pressure gauge loaner. So I picked up some starter fluid and gave it a shot. A healthy 2-3 second spray in the plenum did nothing, no attempt to fire. Tried it twice, same results.
I then tried wiggling the wires at the coil while someone cranked it, no effect there either.
I pulled the #4 plug, held it against the valve cover bolt and then the radiator support. No spark in either place.
I verified 12 volts between the engine and the + terminal on the battery, so I've got a good engine ground.
Rechecked the 15a engine fuse, it's OK.
So, definitely no spark and a lack of fuel doesn't seem to be the problem. Question is, do I change the CAM sensor, or just go straight to the PCM? The coil was definitely bad, would that have taken out the PCM?
