The problem was not the Alarm--(part 2)

Green92LX · 04-04-2001, 12:42 PM

OK...I'm not sure who remembers the last post about my buddy's 88.

The problem is that when you turn the headlights on it triggers the fuel pump, and if the car is running and you hit the lights the whole cluster dies.

I thought it was something to do with the cheesy alarm, but I took the alarm out (there were wires run but nothing was connected!!!!)

Any other ideas?? I hate busting out the books and tracing wires, but it looks like I have no choice.

Any clues?

Check to make sure that there are no cuts or rubs in the wires to either the headlight or ignition switch circuitry. It sounds like one is shorting out the other. The fuel pump coming on could be a hot wire for the headlights rubbing on an exposed wire for the fuel pump and powering it up. I have heard of this happening. Maybe wires are rubbing against steering column.
