Having problems with your 1989 Ford F 150 ?
Fuel Problems I just purchased an 89 Ford F150 with a 302 and it will not start without ether or gas but once it starts it runs on its on and at idle is running rich (black smoke out of exhaust). I've replaced high pressure pump, fuel filter, pressure regulator, and cooling temp. sensor. With key on engine off it has 40 pounds fuel pressure. The check engine light stays on constantly and the fuel pump runs constantly and when I try to get self test codes the light never blinks..it just stays on.
Check for air inlet at carburettor leaks.
