Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
the fuel presure is a little low,sense it does rise when you throttle,this problem would be the regulator,also,sometimes the diaphram will bust in these regulators,letting raw fuel go through the vacuum line,so docheck this...but i think your problem may be the ignition module,these will do this and not throw a code.it is located under the coils auto zone and most parts stores can test these if you take it off and take it to them

INSTALLATION PROCEDURE CAUTION: Connect the fuel return line before tightening the regulator attaching screw in order to prevent the regulator from rotating. Rotation of the regulator could damage the retainer and spacer bracket and lead to a fuel leak at the regulator inlet. NOTE:
The 3X reference signal sent to the PCM by the IC module is an on, off pulse occurring 3 times per crankshaft revolution.
Thanks I appreciate the help I will try the ICM!
also pull the vacuum line off the regulator and see if fuel has been going through it
