i have a 1994 mustang gt with the 5.0. i have been working on this spark issue for some time now. i installed a new computer today HOPING that was the problem since EVERYTHING else has been replaced and the problem continued.so installed the new comp.and the car fired right up top of the key.i let it run for about 3 minutes and as soon as i hit the gas it died and i can not get it started again.so i ran the koeo test and got the codes #564 ( fan control circuit failure ) and code#211 ( profile ignition pick-up circuit fault ) however my fan works and kicks on and off like its supposed just fine, and for the other code i dont see how that could be because i recently replaced the distributor twice thinking it was causing my spark problem.i have replaced EVERY single ignition part on the car twice just incase something was defective and replaced EVERY single sensor in my car twice just incase something was defective and went through ALL of the wiring in the car ( visually examining and fealing ) for breaks and bad spots. still the problem continues,can ANYONE PLEASE give me some help with this????
