its a ? about a 4 inline efi engine:

sometimes when i try to start the engine, i can hear the engine cranking, but it wont start.

i step out of car place it in 2nd gear and push the car forward a little.

i get in and it starts.

sometimes it also suddenly stops running or it stumbles now and then.

could it be a wire/ sparkplug problem?

should i check with a compressiontester?

thanx a lot

The starter might be eating all the volts and not allowing enough to the ignition. Either the starter is using too much power or he batery is low or bad cell or cells. The battery can read 12 volts with worn out cells. Maybe do a load test. Not sure of the other causes.

just a shot in the dark here...Crank sensor? If you can easily access it you can lightly tap on it with a broom handle or something while the engine is running and see if it has any affect. (be real careful around the moving parts!!!!!)

Is the starter motor running and not engaging the flywheel? Just wondered as you said once you push the car forward in gear it will then start. Most engines stop in one of three places when they are shut off so the teeth on the flywheel get wore down in those areas first. Maybe check to see if the teeth on the flywheel are damaged in those areas. I dunno -just guessing!! good luck.
