Default Help would be appreciated

I have read this forum for a long time first post. I'm going to start by saying I KNOW what I did was pretty stupid, but I did any ways now here we are. I have a 96 hardbody completely stock. In my stupidity I decided to drive through high water, I know I'm a dumbass for doing it, but the truck stalled. I believe this was because I was missing a screw in my dizzy cap. Before I tried to start it back I got out and made sure I wasn't gonna suck water in my intake and the water wasn't high enough for that. I got the truck started, ran ruff as hell, but got it out of the water. Changed the oil, took plugs out to make sure no water in cylinders, replace cap and rotor button. Truck ran like a top for about 3 days. It started running bad taking me to work one morning, flooding it's self to death. Hauled the truck home to work on it. Can't figure it out. All my injectors are firing at the same time. I swapped the ecu and that made no difference. The water was up to the bottom of the seats.

The water could have damaged other sensors. Have you tried retrieving trouble codes from the new ecm?

Any water in the cab? The ECM is fairly low being mounted under the passenger seat.

Yea the ecu was completely under water. I swapped with a spare ecu I had that I knew was good, but it didn't change a thing.

I suspect there was water in a connector(s) that shorted pins, at one point. Could be terminal, but could just need a can of contact cleaner, a ton of time and finding ALL connectors for a "once over" cleaning/inspection.

Hard to say, but GL and I'm sure other will have some input for ya...



OH, welcome...

Probably at least as bad as a Jeep so worse than a cow.

Ok I will start that some time this weekend. Can't get any codes off ecu, does the 55 code. I'll probly pick up a scanner since I have had these trucks for several years and plan to have them for several more.
Thanks

Isn't 96' OBDII? I suspect you can scan your truck... first year? ...or was that 97'?

96 and 97 are OBD2.

"I decided to drive through high water" rarely ends well from what I've seen. haha
I've had an unexpected swim lesson after a guy I was with did that.
