I have recently been having some surging issues at WOT. I figure it's fuel or spark. Coil checked out gonna swap out Ignition Control module with a friends good one. But I have an older style double pumper that came with the car might be Reds with hobb switch set at 15#. When I put a jumper wire across hobbs switch at idle the fuel pressure will not move, should FP jump up? Is second pump not comming on?
No knock O2 780mv just when engines hot WOT surging/hestitation, fuel pressure at 20+ boost is over 60#.
