im kinda lost here, i have no tuning tools whatsoever, no wideband, i have bo clue whats going on here.
any suggestions would be of some use to me.
first off this is a 4g63t in a 1980 colt. it runs very well from idle to 1/8 throttle. but anything over 1/8 throttle makes no difference. it is making about 100 horsepower.
i mean, the ecu says fuel pump, it has a walbro 190 in the tank. it could very well be starved for fuel though, maybe the output hose is leaking or something like that, maybe the fuel filter is plugged, who knows
im wondering how the hell the ecu could even detect that?
i also mean to ask if anybodys ever experienced lack of fuel supply before, and if it acts like this. just no power, timing pulled.
