1999 Passport / Rodeo, 150k miles, every so often, more frequently now that the summer temperatures are here, dies. One of two things are happening, either the engine simply stops running while driving, or after driving it a little, even just 2 miles, and shutting down the engine, it will not start again. Either instance the engine will not start again for 60 minutes. Everything else not reliant on the engine running, is fine. Power is fine, windows, stereo, lights, starter, windshield wipers, heater/AirCon fan, etc. When it dies or is a no start, I have to wait exactly 60 minutes, on the mark(before summer it was 20 minutes on the mark), then the truck will start like there was no problem at all. Before this time frame wait, attempting to start the truck resulted in the starter turning the engine just fine, but no fire. Wait the time period and then start, fires perfectly.
Initially it happened more after a long drive and getting off the freeway or slowing down a little, it would just die. Then it started happening when in park with the A/C running. Now it happens without the A/C running, driving, slowing down, exiting the freeway, in park, turning a corner, or waiting in a drive through.
There is 45lbs of pressure in the fuel line, new filter and pump, so I am pretty positive it is not fuel related.
Could it be the ion sensor? Is there a way to test it?
Could it be that all my COP coils crap out at once?
These are the parts I've replaced in my hair pulling chase of this intermittent issue:
New Crankshaft sensor
new relays
new fuel sending relay
New fuel sending unit
new fuel filter
new spark plugs
new aircleaner
new ECM
I am at a complete loss...
Anyone else ever seen this?
Anyone?
Any ideas?
