Bad BAC or driver for it. With the engine idling, pull the connector for the BAC, if the idle does not drop you have a problem with either the BAC or the ECU (its common for the pins in the connector to short out and blow the driver on the ECU). I had this on my car, same symptoms - fixed the ECU and no more problem.

Does anyone know, could the engine timing be causing this problem & the problem of it running rich & fouling the plugs?

bacca

it could be flooding..... when it does that again just do the unflooding trick..



open the hood and unplug the ECU INJ fuse .... turn the engine over for about 3 sec. put the fuse back in and fire the car back up.. works great.... your problem is a classic one for the FCs

The idle drops a couple of hundred RPM's when I unplug the valve.

I have a switch on the steering column tied to the fuel pump relay. It makes no difference if I turn the fuel on or not. I don't think it's flooding, because if you let it sit for 1/2 hour or so & cool down, it starts right up.

could be a bad starter... does it turn over and just not fire or what?? if the starter doesnt turn could be heating up the wires and the wires then see the wrong impedance....

I'm sorry. My post was un-clear. The car turns over just fine. It just won't start.



This problem is driving me crazy. I don't understand how a car that is running perfectly can be shut off (either by the key or turning off fuel flow, it doesn't matter) and not be able to start back up.

It is probably the cranking enrichment circut on the ECU flooding the engine

find the wire that tells the ECU that you are cranking and cut it.
