I searched, but came up with no solution. This weekend I washed my 92 Cherokee to get it ready for a little brake/exhaust/maintenance work. I washed the motor, being careful to not get the TPS wet. While dinking around with the hose, I accidently gave my PCM (ECM?) a full on blast of water. Well, it didn't start so I pushed it out of the bay to let it dry in the sun.
First step, pulled the distributor cap and dried out some moisture that got inside. Still no start. I let it sit an hour. Still no start. OK, I call the wife, have her bring me home and let it sit for 4 more hours. When we drive up to the carwash, the lights are on... The switch is off, ignition off, lights stay on. No start...
The next day, I go to tow it home. When the battery is re-connected the lights come back on. When the ignition switch is on, my electric fan comes on. (cold engine, 20 degrees out)
It has been in a heated garage for 3 days with a fan blowing under the hood.
The lights no longer stay on, but the fan still comes on when the ignition is on, the motor cranks at normal speed, and it still won't start.
I have no spark, I have no fuel pressure at the rail, no current at the fuel pump resistor.
I checked all the fuses and relays, checked and cleaned connections and grounds.
Suggestions?
