Sorry, but this is quite lengthy.
I just installed my Kenne Bell kit with boost-a-pump and the KB modified fuel rail adapter for my 98 return fuel system on my car with some FRPP 80lb injectors.
The car runs like total crap now. It smelled pig rich and vibrated like hell. It wouldn't idle. If I revved it, the vibrations and fuel smell only got worse. I shut it down promptly.
I decided to start with checking the fuel pressure. I read an even 39 psi with no vacuum. I pulled 22.5 inches of vacuum with a vacuum pump and the pressure went down to 30 psi, so I think the pressure regulator that came with the kit along with the adapter plate are both working great.
However, before plugging in the fuel pressure gauge, I had to depressurize the system. To do that, I unplugged the fuel pump cut-off switch in the trunk and started the engine to run the fuel out of the rails. When I started the engine, it ran perfectly, idled, and revved fine for about 5 seconds before it ran out of fuel.
I tried it again a few times with the pump plugged in and unplugged, each time it ran like crap with fuel pressure and ran great without it until it ran out of fuel.
I am running the SCT Pro Racer package with a Livewire tuner. Before the blower, I had the car running great with a bunch of mods such as comp XE268 cams, stroker kit, ported PI heads, PI intake, 90mm LMAF sensor, FRPP 24 lb injectors, long tubes, o/r x pipe, just to name a few.
Now I've added the KB and the 80 lb injectors. I have tuned the vehicle with the correct values for the injectors per both fords website and SCT data files. I checked all values to the injector part number, M-9593-LU80. The injectors are new from Suttonhp.com. The injectors are black with a blue stripe at the bottom and hey are EV6 body style and have USCAR connectors, so they check out as being the correct injectors.
I can't figure out where the problem is.
Any ideas?
