Make sure you have 50/50 coolant and water.i would replace thermostat and radiator pressure cap.replace air filter make sure engine getting fresh air.check radiator cores and front grille from debris blocking off airflow through grille to radiator.if problem continue flush out coolant system radiator engine block and heater core.water going bad cause over heat problems also.

SOURCE: wont start

Take it to a shop for diagnostics. It could be alot of things, but is probably a faulty fuel pump.

Fuel pumps usually fail once the car gets to operating temperature and then they sieze up if they are faulty.

Although it could be alot of other things, faulty computer, to a clogged fuel filter.

SOURCE: car starts fine and runs good until it gets hot

I think you have to check and monitor your engine temperature..Has this risen more than half on the indicator and if it stays there and goes further and does not comes back to half way or less then you have few problems..It may be your radiator is blocked and may need replacing or else it may be your thermostat is not good.But you have to be very careful as this may cause the head gasket to blow off and mess the engine.Check if there is lots of water coming out through the exhaust pipe.Also cross check your water level and if you notice it needs refilling quite often then you have a damaged gasket..Hope this helps and leave me a rating..

SOURCE: I have 90' olds cutlass supreme. I have a problem.

Could be one of many things but maybe either cam or crank sensor... choices are either swap out each part with a known good one, or be fortunate to know someone with the dealer manual that will tell you what voltage should read from each component....chilton's will help but the actual dealer manual will give you more specific info about how to check voltages from each sensor.

1987 Ford f150 shuts off and wont start until engine is cooled off


To clarify, you said it runs for 20 min then quits, and it won't start again until it cools off. Have you checked for spark at the plugs and fuel pressure right after it quits running ?
These models have an ignition module attached to the side of the distributor that has a history of failing when hot. The coil and the pickup inside the distributor can fail too. Could also be a relay.

Hi and welcome to FixYa!

As a first course of action, I strongly suggest that you replace the ignition coil. If the ignition coil gets hot the car may stall or may not start right away till it cools down. The ignition coil is surely faulty and replacement is surely necessary.

Hope this helps and thank you for using FixYa! Have a good one!

I know this sounds silly but Replace the crankshaft position sensor. My guess is it will start shutting itself off soon and restarting when it cools off. I think its just giving you a warning lol.

Had the same problem with 1999 Quest - turns out that the distributor was going until it finally died. It stuttered andf kept shutting off when driven about 20 miles or so. Would start normally when cooled and off again when hot. But yours could be a different problem; not sure.
