I have a 95 Bonneville that when I drive it and park it for 20 - 30 minutes is hard starting or won't start untill it cools down. It acts as if it is flooded. 10 minutes it will start, an hour it will start. 20 -30 minutes forget about it. It's really mindboggeling.

Re: 95 Bonneville won't start when hot
Yes I know, but If you hold the accelerator pedal to the floor on a fuel injected car, the Throttle position sensor will tell the computer to enter clear flood mode. Then the computer will shut off the fuel injectors while you have the pedal to the floor. If it is flooded, you should be able to get it started in clear flood.

engine got probably way too too hot could blowed head gasket cracked cylinder head.depends on how low coolant got if coolant level got close empty probably got engine damage.if coolant didnt get too low wait until engine cool down try cranking it.engine could have got so hot burned out ignition module.
Thanks for choosing FixYa and welcome. It may be the crank but not for sure. You need fuel, air, and fire to start the vehicle. With the loss of electrical components, it sounds like you have an electrical issue. If so, they can be hard to find, even with proper testing. Can you tell me in what order your problems occurred?
I'd have fuel pressure tested. I had a 95' did same thing. Cold winter day, worked fine, as soon as it got warmer, or hot out, it would quit, and re-start 20 minutes later and go for a distance then die again. If I parked in the shade on a hot day, I'd get further before it quit for the first time. I started carrying a fuel pressure gauge with me. Cool in the morning my fuel pressure was up to spec @ 49-50psi. Once it got warm/hot out and it died, Hooked up gauge and it was at 2-5psi. Let it sit and cool off 20-30 minutes, pressure would jump back up and run good until fuel pump got hot again and then pressure dropped off and car quit. It sure sounds like the fuel pump, but the hard part will be getting the car to the shop at the right time, or they will need to let it run on the lot until it quits to confirm the pressure drop. One thing you can try is when car quits, have a can of WD-40 or quick start with you and a screwdriver. Loosen the clamp on the air intake hose where it connects to the front of the throttle body and pull it off. With vehicle off, turn throttle linkage so the plate opens up enough to spray WD-40 a second or 2 in the throttle body. Then try to start it. If it starts and runs momentarily, then you can be pretty sure it's fuel related and my guess is the pump needs replacement.
Can you hear the fuel pump hum when you turn the key to on? If it will start on starting fluid, you definitely have a fuel problem. The pump being stuck or bad, or the filter being plugged, or vapor lock (try loosening the fuel cap, does it pull in air?)
The fan is only supposed to come on when there is excess heat .. in normal driving conditions it doesn't start. When you start your car in the morning the fan won't come on because the engine is cold.
With a hot engine - and it depends how hot the engine is - the fan will only kick in to prevent overheating. In heavy slow moving traffic or a traffic jam, the fan will kick in if needed.
The air flow through the radiator is usually sufficient -in normal driving conditions - to cool the engine.
When you park up and the car has a hot engine, the fan will kick in. This is perfectly normal. It is caused by a surge of hot coolant triggering the fan sensor. Perfectly normal.
The fan then should cut out after a while .. maybe 2-3 minutes at the most. If the fan runs continuously that suggests a fault in the temperature sensor switch.
Next time - wait by the car and see how long it takes for the fan to quit after you have parked up. It should stop of its own accord after a couple of minutes.
If the fan cuts off after a short while, and your battery is becoming drained, that's probably a battery or alternator fault.
Remember: when you start the car the fan won't kick in at idle speed because the engine is COLD, and there is no reason for the fan to start up ..
The fan WILL kick in for a couple of minutes after you have parked the vehicle and the engine is hot
the neutral safety switch is probably faulty the radio says safety because the wrong code was entered 3 time key needs to be on for 3 hours hook up battery charger check engine light may be code for trans issue
