Ignition System Won't Start Not applicable Not applicable
Q: Hi. My husband went to start his 1988 Mercury Tracer and when he puts the keys in the ingnition, the horn sounds. It doesn't even get to the point of attempting to "turn over". When he takes the keys out of the ignition, the horn stops. We cannot determine why this is happening. It almost seems someone has wired the ignition/starter to the horn but we didn't think that was possible. Any ideas would be greatly appreciated.
A: I think the horn wire has a bare spot in it inside the steering column and when the key is inserted, it provides the ground path. Just like pushing the horn button. Ed
Q: I actually have two questions for you. I have a 1988 Mercury Tracer 2 Door Blue Hatch Back. The problem I'm having is when I pump the brakes the car stalls out. When I start the car and open the hood the enigne vibrates. The car only stalls out if I apply the brake or go slow when turning. I had It checked out by a mechanic and the man told me that I might have to replace a part near the front where the air filter is. I had a lot of repairs done to this car. I had rear struts put on, new muffler, new front axle's, front rotors, front and back brakes, new front calipers, new tires, new spit fire spark plugs new rotor & cap. And I'm having the wheel cylinders in the rear done along with the flex line hoses that are cracked on both sides. My dad mention that my spark plugs might be off that's why it's stalling when I pump the brakes. The other question I have is my insturments panel lights do not work and I don't know why. I replaced all the fuses in the fuse box that did not work, so I changed all the bulbs again that did not work. I have a roll wheel to turn the lights on low or high I don't know if that is shot or not. It comes on once in a while usually when I slam my door. I replaced the bulbs in the door, the cig lighter light, the hatch back door light, the dome light, the gear shift light, and still nothing.
My main concern is why my car stalls when I apply the brake? I know that when I open the hood the engine vibrates and wants to stall out.I can be reached at my e-mail address at Blake_may@yahoo.com thank you.
A: Your stalling problem is most likely being caused by a vacuum leak at the power brake booster. The vacuum line may be loose or broken or the booster itself may have a ruptured diaphram. This will also cause the rough idle you have.
The light problem could be a bad headlight switch.
