1994 Park Avenue. starts then wont start

same with mine crankshaft and cam shaft censors. one starts car then other takes over. unless you are good with cars take to mechanic u should have a check engine light on also

QUESTION: Without a jump, does the motor crank when you turn the key to "START"?

...

If you can jump start it, then you know you have spark, fuel and compression; you know your starter and ignition are fine.

My guess is a loose/missing connection at the positive battery terminal for your starter.

Does the temperature gage on the dashboard show that the car is getting warm?

how long did the starter last for that you bought ??? if its still under warantee then get it replaced as thats where your problem is at

Could be any of several things but most likely to be fuel starvation caused by anything including a foreign body in the fuel tank, tank breather, weak fuel pump or semi-blocked filter.

Lots of checking which might not reveal much due to needing to drive a couple of hours before the problem happens.

If your car has a crank sensor by the crank pulley replace it car starts runs grate shuts off like some one turn key off but starts back up maybe runs a little longer or the same

The problem is your Vats security system. This causes the car to either "not start" or "shut down" while running. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, (if not starting)turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start.

----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites. I just did the NEWROCKIES bypass on my regal. Worth the 200 bucks, did it myself in under and hour

Check the connections to the starter for corrosion gets everywhere

Doubt it. Sounds like a crank sensor.

the relay can be found in the fuse box thats located under the hood open the box and look for the fuse or relay that says fuel pump. this fuse box is usually on the drivers side of the vehicle but it can also be on the passenger side.
