Dash indicater lights stay on

[ButchJ]

1993 Dodge 4+4 dash indicater lights ABS, Water in Fuel, Brake light are staying on after start any ideas? Cruise Control and every thing working fine. Disconnected Batteries and no change.

Ahhh, I had one on a 91 and it ended up being the PCM..... Maybe someone has something I don't know?!? Cerebrusiam might know..... where'd he go?

So what was the fix? Pretty sure it is not with the ground connection. Something got wet! You would think a small amount of moisture would not cause such a problem, but I guess it did. I cleaned the connector (running from the fuel filter to the harness. ) No results. So I guess it could either be the connector from the filter, or somehow the PCM. I covered the PCM and the TPS with plastic wrap as well as the air filter before "detailing" the engine with Griot's kit and low pressure spray. I did not cover the fuel filter connections. I drained some fuel from the filter and it was clean with not a trace of water. Oh, I also added two bottles of Lucas diesel and gas treatment to tank and filled before detailing the engine. So the "water in fuel" light remains lit. Thanks... .

Have you unplugged the Water in fuel connector to see if the light goes out? If it doesn't, then you have either a wire rubbed and grounded somewhere or a faulty PCM.....

Yes, I did unplug the connector and the light went out.
All back to normal after I disconnected the plug from the harness and sprayed a liberal amount of electrical parts cleaner

on both connections and blew dry with a hair dryer... Thanks to all for the advice. Lesson? Don't use a hose or pressure washer under the hood without Saran wrapping the wif connector wires to the harness. Of course it could have been the wires at the filter end, though I cannot see how... . And I would NEVER leave the TPS or PCM exposed... .
