okay, i have gathered tons of info from the search already, so any further info would be appreciated!
98 4.0 AW4
engine won't start, cranks, just doesn't fire.
-it's getting fuel pressure to the fuel rail.
-is not getting spark from the coil.
-pulled a code w/ scan tool- indicating code p1694- no output from pcm.
-i'm getting ~5v to the cps and tps.
-instrument cluster is dead. according to my search, that's indicitive of a bad cps, but i checked resistance, and all three wires are indicating an open circuit.
is there any way to check if the pcm is still functioning properly? (it was submerged in water a few weeks ago)
also another strange thing to note that may or may not have anything to do with this. two days ago the truck ran normal. yesterday when i went to start it I noticed that whenever the key is on, the rad fan kicks on. this wasn't happening when the jeep would run. coincidence, or is this telling me something? any suggestions would be great! thanks!
