Off boost it's fine. Runs great. It's really hard to start, though. I have to lean on the ignition for almost 30 seconds sometime before it starts to turn over on it's own. Under boost, my af gauge starts to spit out .07, then .06, then .05, slowly dropping until i let off the throttle. It also sputters like it wants to die when i give it more throttle under boost. I can't tell if it's getting too much fuel, or not nearly enough. Here's my thought: How well does that walbro actually fit our cars? I'm not the one who installed my fuel pump, so i don't know. 95ESi says that it was "wobbly" at the attatchment to the fuel line. If it doesn't make a good seal, could it build up fuel pressure? A FP gauge is the only thing i don't have, so i can't tell (tire presure gauge on the service fitting? :-] ) But the way it seems to me, that seal might be bad. The fuel pressure might leak back into the tank, accounting for the hard starts because the pump is having to build back up to 47psi. I might account for the bad boosting, as it might not be able to build enough fuel pressure under boost as the fuel is blowing back into the tank. Could it be ? I'm going to check the seal and fit of the pump myself tomorrow.
