Phantom water in fuel light

Postby cougar » Sun Oct 11, 2009 8:03 am

I keep getting this phantom water in fuel light even with the sensor disconnected on my 92. It comes on when you are stopping. Take your foot off the brakes it goes out. It does not come back on if you put your foot on the brake again while stopped.
Any ideas?

The first thing I did was unplug the sensor to see if it was a bad or improperly installed sensor. Made no difference. The only connection between the wif and brakes is the cruse control brake switch through the computer. I hope I don't have a :pottytrain: computer.

I can't remember, but are the brake light on the dash and the wif light close together? Could the lights have been put back in, in the wrong spot's?

Gear jammer- not possible, as the bulbs plug into a printed board of some kind. Think of the dash lights in the instrument cluster.

cougar- try spraying some WD40, PB, etc, into the connector and see if that alleviates your WIF woes. Long shot, since it isnt steady, but it will eliminate one possibility.

OK, I couldn't remember how they were set up. I still think it could be a grounding problem.

2 points Dan!
I pulled all the connectors I could get at and cleaned them. Problem solved.

Nuts, it came back after a couple of days. I guess I'll be chasing wire. It does the same plugged in or unplugged.

or you could just do the simple solution, pull the bulb out of the socket like I did! :lol:

I have a spare PCM coming. I'm going to play with that.
