CAR RUNS AND DRIVES GREAT. USUALLY.
RAN THRU LOTS OF RAIN WATER ON THE STREETS.10 MINUTES LATER CAR DIED AND WILL NOT START. CRANKS OVER. JUST WON'T START. THIS WAS 3 DAYS AGO. WE TRIED AN IGNITION MODULE, THAT DIDN'T FIX IT. IT HAS BEEN DETERMINED THAT IT HAS POWER TO THE COIL, BUT NO INTERRUPTION. " MECHANIC" CANNOT DETERMINE WHERE FAILURE IS OCCURING BUT OBVIOUSLY WE HAVE AN IGNITION FAILURE (?)

DO YOU HAVE ANY SUGGESTIONS TO WHAT IS MOST LIKELY TO BE THE POINT OF FAILURE?

THANK YOU!
Do you
have the same problem?

The obvious is water in the distributor, has the cap been removed and checked?

YES. THAT'S THE FIRST THING THAT WAS DONE. DID NOT APPEAR TO BE WET THEN. AND NOW IT'S 3 DAYS LATER, AND STILL WON'T START.

Check the connectors on the transmission, on the right side is the trans position switch, see if it's full of water. Can you determine how high the water got? Check all connectors to that level, This is a no spark problem? Check engine fuse box too.
HARD STARTING (CRANKS OKAY) If vehicle cranks okay, but is difficult to start or starts and immediately dies, check the following items: Ensure sufficient secondary spark is available. Ensure distributor pick-up coil resistance is within specification. Ensure distributor pick-up coil air gap is correct. Ensure ignition coil resistance is within specification. Check for low compression. Ensure no vacuum leaks exist. Check fuel pump or circuit opening relay. Check fuel pressure. Check for faulty in-tank fuel pump check valve, allowing fuel from lines to drain back to tank after engine has stopped. Check EGR valve and solenoid operation. Check air intake system for restriction. Check for cracks or poor connections at throttle body. Ensure ignition and valve timing are correct. Check for faulty spark plug wires. Ensure noise suppressor (if equipped) has correct resistance. Check operation of air induction valve (if equipped). Ensure Coolant Temperature Sensor (CTS) has correct resistance. Check Throttle Position Sensor (TPS). Check Manifold Absolute Pressure (MAP) sensor. Ensure all fuses are okay. Ensure Idle Air Control (IAC) valve is operating correctly.
