Car will start and run until it reaches operating temp. Then it dies and will not start for several mins. 1988 Royal 88 3800


MAF sensor is located between air filter and trottle body. During warm up take a screwdriver and lightly hit the MAF sensor if engine stall. then you have MAF sensor defect.
other thing is crankshaft sensor behing the harmonic balancer could touch metal when engine is hot enough have a look then good luck

It has rough idle when you first start it then straightens out after warming up


sounds like low compression at start up do to piston slap and not alowing car to warm up over the years before driving off. 3.1, 3.4, 3.5 motor pistons are exact size at operating temp there for cold temps at start up cause the pistons to slap the cylinder wall.. Gm engineers did this to reduce operating temp while driving by lowering friction in the cylinder. problem is most people these days start there cars and take off down the road..my suggesting would be to check piston compersion at operating temp and see if it meets spefications for ur mottor before replacing any other parts...

Won't start when engine is warm, starts fine when cold and at normal operating temp


You might want to make sure the vehicle is not overheating. If all checks out, it may be in the ignitions, spak plugs/coils, wires. It could be a leaking injector. Keep in mind, it needs air, fuel, and fire to start.

My 2004 RX8 won't start when the engine is warm, when its cold it starts no problem. If I drive the car till it at operating temp and shut it down I have to wait an hour until start it again


if this car is on the cold start injector when it is defective. Injects additional fuel to the engine is still warm. Is it to feel warm by running more than normal gasoline smell?

When outside temp is above 80 degrees, engine will not start after running for a while. maybe vapor lock? After engine cools, 15-20 minutes engine starts.


Check the Engine Coolant Temperature sensor. If it is faulty or disconnected, it will tell the engine computer that the engine is still fully cold even when it is actually warm. The computer will then schedule too much fuel for a warm start--flooding the engine. You wind up waiting for the excess fuel to evaporate and the engine to cool down some and "match" the faulty sensor before it will start.

Another possibility is a leaking fuel injector. Again, a warm engine with too much fuel dripping from an injector will flood.

1991 Chev Beretta blows cold air


Hi!
Looking at your description I feel a Air lock scenario?
Have you tried a system bleed?
Park vehicle on level ground, when cold remove coolant filler cap, start engine leave to idle, turn heater to max and blower full. Wait for engine to reach operating temp, keep clear of coolant filler, listen as hopefully gurgling then a boil over will occur, top up with very warm coolant wait as it may boil over again.
Check for heat inside vehicle, if hot replace cap but keep eye on temp as air lock may have just moved out of heater matrix/core so boil up may happen again.
If the bottom hose continues to constrict and heat inside car then possible head gasket issues.
Good luck! hope I sorted it for you? if so press the Blue button please! for my FREE effort's I Thank You!
