My 1991 780 Bertone Coupe has not been starting when left on the parking lot in the sun. I've replaced 2 starters this summer but it still keeps happening. My mechanic is stumped. The only comm


If the car is in a secure area, raise the hood to vent air from the engine compartment when you park.

The symptoms sound like Vapor lock or a bad coil. Check fuelpump pressure when it acts up again.

If this vehicle has an ignition Relay, or a Fuelpump Relay, they may be affected by heat. Replace those Relays.

I am thinking the starters failed because of extreme cranking usage. Next time you replace one, get a Lifetime gaurantee.

There can be a strenuous condition for a starter when the engine is overadvanced. GM had a problem with its Crankshaft sensors which kept the Cams overadvanced and it fried the starters when the Owners tried to start their motors. But this was not due to heat and occured on cold motors too.

I hope my solution is helpful. Please rate my solution.

i was told that if the jeep all of a sudden didnt start on its own without giving it gas, then next time you start it hold the pedal all the way to the floor and it resets something in the computer and sets you back to normal.

Hard starting when cold ( engine cranks normally )


see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary

89 jeep wrangler wont start


Sounds like the drainback valve inside the pump is shot...try just turning the key on and waiting a minute and see if it starts that way.
