1990 bronco full size 160000 miles. When I depress the clutch and turn the key all the warning lights go on, but won't start. No noise. Often it will start after a couple more tries, sometimes have to wait quite a while. It has never done this before. Once going to runs very well. It acts like a vapor lock.

1. So the car was running normally and then on one occasion you put in the key to start it and all the warning lights flash up on the dash and the starter motor will not turn the engine over. Is that correct.

2. When you last drove the car were any warning lights appearing on the dash.such as check engine warning, engine overheating, electrical charging warnings etc.\

3. Has any work been carried out on the car recently.

4. How old is the battery in the car.

The clutch is operated hydraulically, and there is no adjustment. If your problem is that the clutch will not disengage or is hard to disengage you may be low on fluid or have air in the line. There may be a leak either at the master cylinder or the clutch slave cylinder. Bleeding the slave cylinder may restore pedal pressure. If the problem is that the clutch engages high on the pedal the problem is likely a worn clutch disc.

you may have a bad clutch switch which will only allow the car to start with the clutch pedal depressed.it allows power through the switch only with it depressed to start the car so you won`t start the car with it in gear causing an accident.there will be a switch that the clutch pedal pushes against that allows power to flow through it to start the car.there should be power on one side with the key turned on and power on the other side with the clutch depressed.

Check your coil or points in distrubuter., good luck to you.

Check your main wire connector plug. Left side behind wheel well

the drive is not kicking out on the starter. or may be loos.

Hi:
You need to check your clutch master cylinder reservour, not your brake cylinder. It is located approx in front of the clutch pedal, outboard of the brake cylinder. If it is low, you need to inspect for leaks around it, the lines connecting it to the clutch slave cylinder that is mounted on the transmission.

check to see if you are getting fuel to the carb. if you have fuel then check to make sure you have spark

Remove te cross pins that hold the caliper and the brake pads in place, then remove the caliper bracket, there are 2 bolts at the backside, then the rotro just slides off, clean any rust on the rotor mount area while the rotor is off, then using a large clamp depress the piston in the brake caliper and reinstall in reverse order, one word of caution, use quality replacement parts, Wagner is very good, if you don't use good parts you will end up with poor brake performance.

Check for timing gear problems. They have plastic teeth on the cam shaft gear which will shatter causing it to jump time.
