[QUOTE="hunglikeatunacan, post: 16962114, member: 205125"] also thank for helping with this issue and what determines fuel pressure of how much to supply when your at idle of on the throttle i have a mechanical boost guage and vac and boost is normal when this is all happening 21 psi at idle also when it starts to go up to or over 100psi if i give it full throttle it drops it back to 60 psi but as soon as you let off it goes right back up 100 or over. if you turn off the vehicle and restart samething but with a scantool if you rteset the memory for fuel, idle . also only way you can clear any of the check engine codes. it will set a code for fpdm circuit high or module disconected when fuel pump fuse blows i have gotten rich conditions if fuse dont blow sometimes. if you reset the memory. and restart it it will drop back to 40psi at idle and able to drive again but it may only last about 5 to 10min this time for it to peg the fuel pressure again, so definetly issue whit the car running longer period as when car is cold start it can last up to 3o to 40 min before starts to happen [/QUOTE]
