97 GTI Golf Cuts out and then starts. HELP!

[jinnahflaxi]

Hi All, I have a Golf mk3 GTI 2.0 8v, I have had this problem for approx 5 months. When driving, at any time the car cuts out when it wants, as though the ignition has been turned off. If i am moving the car sometimes restarts itself. If i come to a stand still i have to start the car my self after a few minutes of trying. Sometimes if i have been in the car, parked up and come back to it, it won't start the first time, but after leaving it for a few minutes/seconds it starts.

Last week I was on the way to work one day a couple of weeks back, and the car lost power, so I pulled over and tried to start,which it did, but then cut out and hasn't started since.
Called mechanic who ran tests as there was no spark and then he
started the illimination process, firstly changing the coil, then distributer and cap, then the crank speed sensor, still to no purring of engine.
Managed to get a second hand ECU with Ignition key but Mechanic tell me that i need key reader with this ECU. Where will i got that?
Can anyone HELP?


P.S. Do you have any ideas Boschmann or Anyone?

try a new alternator. put a battery you know is fully charged and try to start the car if it starts and then dies it means your alternator is dead.

New coil, distributor, ignition switch & ECU? I don't know what you mean by a key reader. Has he checked for engine codes? Do you hear the fuel pump for a second when you first turn the key to on position? Perhaps the ECM power supply relay or wiring at the fuse box is bad.
