Car engine keeps going off even whilst the car is in motion. engine starts after several attempts.

To remove the spark plugs and crank the engine round to rid the engine of the hydrolock is the correct thing to do.
Check there is 12volts getting to the starter motor and that the solenoid opperates correctly.
Recheck your wiring.

If the engine has started, the safety interlock is bad. (an electrical interlock. Or the linkages to the shift lever are bad, or the bushings on the linkage, or even problems with the shift lever pivot.

Jump starting your car is not going to fix it cause its more likely to be a wire problem.star at your brake light and see if your connections are tight and then go from there..sounds like a short for sure...

Check to see if it is flooded, When you attempt to start the car put your foot on the accelerator and put it to the floor, keep it to the floor whilst trying to start the car yet dont pump the accelerator just keep it flat to the floor.

If it turns over the starter motor is fine,

Fuel Filter and pump is fine,

You got a spark so the electrics will be fine,

Just need to limit the problem down to whats happening under the head.

since the engine is overheated and died whilst in motion,surely you have either blown head gasket or a cracked cylinder head and pistons marked the liners, In other words the engine might need recondition.

It sounds like you could have one of several problems. It could be the starter motor dragging but that shuold be more consistent. A come and go problem usually is a connection issue. The solenoid could have worn or loose contacts, battery connections making but not very well, starter wiring loose or poor connections, things like that. It could even be a ground connection not getting good contact. I hope this helps.

did you run out of gas or did the pump fail ?? have you bled it off on the fuel rail ,look on the fuel feed to the injectors and there is a tyre valve looking thing ,take the dust cap off and then push it in with a something whilst someone cranks engine and see if you have fuel coming through

believe u hav a bad computer--1st go get car scanned at a parts place to rule out sensor etc problems--also hav u had a tuneup-new plug wires and dist cap etc--mite giv it a fuel pump and pressure regulator test-just dont start replacin parts for the hec of it

Bad contacts in the ignition lock cylinder.

Have someone try to start the car whilst you attempt to move the battery and cables. If you are able to have full power and then nothing and then full again, it could be your battery cables. Replace your positive and negative battery cables. While you have the car's batter out, have it checked to see if it needs replacing too. You wouldn't think a moving part would go bad but sometimes they get corroded or start shorting out. Good Luck.
