Car runs briefly and dies

[Stale man]

New battery, coil and module. Car will start, run briefly and then dies. Scanmaster shows no readings whatsoever and keeps trying to reset itself. Voltage readings as I last recall were in the high 12's. There doesn't seem to be a ground problem and I'm guessing it's the alternator. Any suggestions?

ANYONE!!

You are not using an anti-theft chip are you? It will do exactly that. An alternator should never be able to let it start and stall.

Put a battery charger on it and start it, the charger emulates an alternator.

Do you have any spare chips? Mine was doing this and it turned out to be a bad PROM.

I'll try to recharge the battery and I still have the stock chip. I'll try both and we'll see. Thanks

If you have a fuel pressure gauge you might check to see if the pressure on the fuel rail is still there.

 

[Stale man]

Good point. I'll try it. The only thing is is that the better the charge on the battery the longer it seems to run......even if its for 10 seconds.

What do you have for a fuel pump and hot wire kit?

 

[Stale man]

The pump is the one from the Poston catalog

Piut a voltmeter propped up on the battery where you can see it from the driver seat. Crank it up and see what happens.

Does the dash oil light turn off?
