When the starter motor is working there is reduced power available for the the ignition system. pushing or pulling allows full power for the ignition system. faults include starter motor problems (poleing out draws to much current) incorrect battery size,faulty earth strap between the engine and battery. fault could also be in the ignition switch in that when in the start mode there is no circuit to the ignition system

The first thing you would need to know is why it won't start on its own.
It could be the key switch or a list of other things.
Try to narrow down the choices, fuel, ignition, or compression.

SOURCE: Truck sometimes starts, sometimes quits after running

It sounds like you have a defective fuel pump or a bad fuel pressure regulator.

SOURCE: Ford fiesta keeps stalling

Hi

The problem is with your Idle Control Valve.

Look in the middle of the engine and you will see a plastic air box. Fastened to this will be the valve, a small cylinder with a wire connected to it, should be held on by 2 bolts

Undo the bolts and remove the valve. Spray WD40 into the two holes until it runs clear then rinse with petrol and let it dry.

Replace and bobs your uncle, should work fine.

You can replace the item for around £25

For the ECM 1 fuse to open you obviously have a short to ground , start with the injector disconnected and see if ECM 1 fuse still blows.If it does disconnect crank sensor, also inspect wires for the injectors or any rub through wires here is a diagram cansmo_178.gif
