2006 lbz washed motor wont start

[Clint330r]

I have a 2006 lbz i washed the motor yesterday in my driveway i sprayed some cleaner then rinsed it with water. I got in truck today to move it all the lights on the cluster was flashing on and off. Sometimes it will try to start when i turn key to acc. but it wont start. Also when when i disconnect the tcm all the light in dash and everything acts normal could the tcm be bad and can i just replace or do i need to program a new one thanks

Thats pretty odd I always wash my motors and never have an issue. What are the temp there? You may have got some water somewhere and it hasn't dried out yet. Got any way to heat and dry out the engine compartment faster?

Temps around 60 today I parked it in the sun opened hood and disconnected most the plugs but only one that would make truck act normal is if I disconect Tcm

Ground the tcm case to the battery ground and see if it fires up...

Ok I will try that by grounding it would that also kept my cluster from acting up?

Might wanna check battery connections as well. Definitely something goofy goin on there, but weird things happen with weak batteries and bad grounds.

Go buy a can of WD-40 and start disconnecting plugs one at a time and spraying them, especially the ECM (completely disconnect and spray) and the TCM, silicone spray works also..

WD-40 = water displacement formula number 40....

Update I put Tcm in font of heater for about a hour sprayed all connections with electric cleaner and all good
