Engine runs 10-30 mins then quits HELP!!:(
Hi all,
I'm in desperate need of help here. Engine quit, wouldn't start, no fuel pressure,replaced pump.
Two weeks later again, distributor code from PCM, replaced with new distributor & crankshaft sensor. Engine now will run for about 10-30 mins but then quits, turns over but no spark.
If left to cool down for 2 hours or so will start & run again, also bluish black smoke coming from exhaust a little at first then increases. PLease Help I'm totally stumped on this one, also no trouble codes are showing. All help is greatly appreciated.

Bluish black smoke usually indicates that you are burning oil, and increasing temp and smoke together tends to confirm it. That is usually valve guides or rings, a relatively expensive repair.
As far as your no start / no run / no spark problem, look for an "Automatic ShutDown" relay. They can be problematic and not throw codes.
