The fuel pressure was way up which led us to believe it was overloading and bogging out due to a bad regulator, now it does fire right up and will idle no cracking or backfireing there does seem to be a loud sucking noise somewhere in the engine compartment, but I cant find a leak, the brake booster thought is a good one, ive been suspect about my brakes for yrs,. It is possible that I kinked a line stuffing the tank back in but I am smelling some burning and looking for a probable ground issue, which could take yrs to find. total pain in the butt on this one.
