Electrical problem
1994 Buick Park Avenue V8 Two Wheel Drive 140000 miles

Over a month ago the car began intermittantly not starting. Mechanics changed the starter and when that didn't work, the starter relay. The mechanic said the next step would be going through the wiring harness but I am leery because when I had the same prob with my saturn all of my electrics got screwed up. (As in the horn would go off when you locked the door and lost a bunch of deq sensors) I am wondering if this key relearn thing should be tried first? Is it the same on every year? Is there a way to test it before allowing these people in my wiring harness. Currently the mechanics (they are mobile) have missed our last appointment and are not returning my calls. I don't have money to take it somewhere else and start over. : ( Should mention, all the electronic stuff works when key is turned just nothing from the starter, if I keep trying to start it it generally takes 3 or 4 minutes of constant retrying to start. Other times it starts first try.

When it doesn't start (I am assuming that the starter doesn't even click), do you happen to notice the SECURITY light on the dash flashing?

I wattched for it yesterday. I tried waiting for the light to go off and it didn't make a difference. Still wouldn't start. And yes, your assumption is correct about no clicking. So then I just went back to trying over and over till it finally turned over. Later in the evening, after it only taking a couple tries to start it I noticed the security light on even after I was driving. It turned off after a ffew minutes. I can't say that I have noticed whether it always does this or not.

Based on your answer, I have reason to believe that the problem is not within your starting system, but rather in your anti-theft system.

See, with SECURITY light on, the Pass-Key II module cuts power to the starter circuit. After a few minutes, the system resets itself, restores power to the circuit and you can start.

If you wish to have the mobile mechanic to check, tell him to check the security system diagram (the module, sensors, and find out how come your SECURITY light stays on too long). Also check the starter enable relay.
