Check for vacuum leaks. It sounds like the carb may need to be adjusted.

Your truck will not turn over when the key is turned if the battery is dead, the ignition switch has failed, or the starter is bad. All can be readily repaired at a local mechanic or dealership.

take out distriburtor and turn all the way around make sure number 1 cylinder is all the way up same thing happened to meAnswermine was actually the number 6 &8 spark plug wires were crossed made it backfire through the carb

That is caused by too much gas getting into the engine after the key is turned off. If the mower is new enough to have a anti-backfire solenoid on the bottom of the carb then it must not be working. If it is an older mower and doesn't have one then the carb needs adjusting to back off the amount of gas.

Engine timing is VERY retarded. My first guess: the distributor clamp has loosened.

Yes, they have the exact same meaning.

User Avatar

why would you want to turn it over? you can use jacks, a light and a creeper to look at the bottom, less expensive too!

Probably a bad ignition switch.

My truck has the kill switch the kind that is a long little switch the thing is it is on the postion but the truck still is not turing on. I replaced the ignition switch and have a new battery. How do I just remove this so that i can just turn on my truck, 1996 ford ranger.

Check the timing in the caravan. It sounds like the timing has jumped, and the engine could backfire then not start, and could not even turn over.

There are several different reasons that a Chevy truck might not be turning over. You might be out of gas, your battery might be dead, or your starter might be bad.

Mybe your starter died. They are usually about $50

User Avatar

It might be overfueled but it also might be just that when you turn the key off the motor runs on a bit and puts fuel into the hot exhaust and it ignites it and makes it backfire.

Pull over turn off the engine and get out of the truck and call your dispatcher.

User Avatar

You can only do this in park ... Turn off your truck ,apply the parking brake and turn your truck back on .

User Avatar

The most common reason for a vehicle not to turn over is a bad alternator. If the alternator is not charging the battery the engine will not start, regardless of the battery age.

User Avatar

my first thought would be to check the starter . if you can tap on the starter and it starts after that..you have a bad starter .

Turn engine over and observe is distributor is rotating

make sure the spark plug wires are firing
