Question Asked: 96 Grand caravan Will not start
December 29, 2013, 10:56 AM
As per my previous post I replaced the PCM on my 1996 Grand caravan which started out as PCM not sending a signal to to 2 cyl's on the coil pack. Purchased a reman PCM and it started right up but had a bad miss presumably from the two cylinders that were fouled. Bought and installed new double platinum spark plugs. Now it will not start at all. No check eng. light and no codes to be found. I can hear the fuel pump and there's pressure at the rail. Tested for spark and I have spark. How is this possible with no ignition?
Question Asked: P0351 Result of PCM failure?

Van developed real bad miss. P0351 rec. coil pack circuit. Replaced coil pack. No change. Heard of faulty intake & clogged injectors. Sprayed Starting fluid around intake, no change in engine operation detecting no leaks. Disconnected fuel injectors one at a time at idle. Cyl. 1&4 no change in idle. Used screwdriver to listen to injectors. All getting ticking as it should be. Decided to change intake and clean injectors as a CYA move and was only about $30. Still no change. Ran compression check on all cylenders, 120-125 pretty even on all 6. Detected no fire from coil at 1&4 even with new coil. Checked PCM signal at harness plug with noid light for all 3 drivers. Grey wire (1&4) no signal, RY=good, UT=good, leading me to believe the PCM is at fault. Am I correct in this or could there be another gremlin in my engine?
