Default Zd30 went swimming

Hey guys
Really ballsed up yesterday. Got my navara stuck in a big puddle and she flooded. Sat there for probably 2 hrs. Cab full up till just under the dash. In the front bit more in passenher side than drivers.

Got it out and i definitely have water in the gearbox white milky goo dribbling out the top of it when its been running for a while. But problem im having is she drove for km or 2 to get me out of the track. Then started dropping revs to 500rpm in gear. She qont drive now. Revs in neutral but in gear it wont rev. Sometimes i can coax it to move and build revs slowly then it seems ok. But will drop to 500rpm ahain after literally a few moments.

Im thinking the TPS has had a nasty bath. I tried spraying contact cleaner around today but without pulli ng any plugs apart as i was on some fellas lawn where i asked to leave the car. Amd had my young bloke with me so not exactly ideal conditions for qorking on the truck. Im going to tow it home tomorrow or the next day.

Was hoping for anyone thoughts on what they think the throttle fault is. Am i on the right track with TPS?

Did the NPS test amd revs drop in all gears with heat switch on.

Cheers gang

Sounds awesome... Not...

Anyway, the ecu is in the cab, under the centre of the dash, below the radio. I'd be looking at this too, make sure it is nice and dry. Then as you have mentioned, start spraying the electrical connections. Was the vehicle level or nose down?

Nose down. Very wet up around all those pesky electricals. I was surprised how badly the doors let water in.

Yeah not good hey. Hopefully it hasn't killed the ecu for the injector pump. The best thing to do would be get some contact cleaner or wd40 and give all the electrical connections a good spray and see how she goes. I take it you have a snorkel on it?

Yeah have a snorkel. But im thinking the oem snorkel is shithouse. The cyclone drain lets water in. Air filter was damp.

Going to pick it up tomorrow on a trailer. I sprayed around the elec connections with contact cleaner. But when i get it home i will unplug the connections and give it a real good clean and dry in all the connections.

Where is the injector pump ecu?

The injector pump has a small ecu on top of it. Hopefully that hasn't been drowned. I think it is there to control the timing advance but not completely sure as I have a yd25.

Someone else should be able to let you know for sure.

Ecu on the fuel pump should be sealed, wouldn't be a problem.
If you had water up to the bottom of the dash the ecu on top of the trans tunnel probably went under.
10mm socket to remove the 2 mounting bolts and to walk the connector plug off the ecu . Access from the drivers side next to where the brake pedal is.
Pull the lid off and let it dry out and spray the plug. Do the same for the plugs on the accel pedal.

Probably should check the transfer case and front diff to, they might have water in them as well.

Got her back to HQ on the trailer today. Stripped the interior amd carpets. Pulled apart and Sprayed every plug i could find. Left the ecu in position just unplugged it and sprayed. Definitely got wet. After reading your post rumpig ill take the cover off tomorrow spray some more and let it dry

And i was going to do all the fluids in the driveline before this accident anyway had them all in the tray haha. Went and got some cheaper oils today to do some flushes to try remove the water from the GB and anywhere else in managed to find its way into.

She went in passenger side deeper than drivers so i dont think fuel pump ecu went under. Good to know its sealed anyway. Im definitely going to delete the cyclone and get a dual battery snorkel mid pipe to give it half a chance of actually being water tight!
