Coil Problems

[Cricket]

1990 Ranger xlt 2.3
Ran truck thru deep water. Everything got wet. No spark out of 2 & 3 on coil pk on passanger side. Put in new coil pck, spark plugs, ign module checked out. Did spout test, it was okay. Checked all relays & wiring. All was ok too. Engine light stays on & won't let me draw code. Truck will run but tac not working.

Check that the ignition control module has a good ground. I had a 2.3 doing the same thing and cleaned the mounting surfaces and added an extra gound wire and it seems to be running better. Did not have time to see if the primary coil is firing on all 4 but the truck is now drivable.
