Starts everytime until I clear codes then have to keep trying until fan starts running then will start.drove good for awhile with check eng. light on but has just started quitting while driving ; but so far starts back up. any help appreciated.

Answer Hi Mark,
I am not sure what is the relationship of the fans or their codes to the no start/quitting while driving. But I suspect the 0403 which points to the egr valve solenoid circuit may be the cause as that circuit uses the output of the autoshutdown relay and that relay output is also used by the spark coil and fuel injectors and the alternator so if that egr circuit were shorting out that source you can see how it would shutdown the engine. It is carried on dark green/orange wire from the inboard pin of the ASD socket to a splice located at the rear of the engine in the center-top where all these items split off. So check that wire from the egr solenoid to the splice and the other part of the circuit is from the solenoid to pin 40 at the pcm on a gray/yellow wire. There is something shorting intermittently.
