Question about 1990 Ford F150
My truck recently just quit running while on hi-way going @65 mph, having no problems prior whatsoever. It will start and idle, but dies when you give it gas. If I gently give it gas, I can move it, but once it starts moving faster, it suddenly dies out again. After it dies, it's hard to start again and shakes like it's timing. I have checked the timing & fuel pressure, both good, & within last 2 yrs. have replaced fuel filter/res., hi-pressure fuel pump,& fuel pressure reg.; new coil, distributor, ignition module, cap, rotor and wires,& battery's good. All vacuum lines and elec. con's. good, so I bought a new fuel pressure reg.(thin diaphrams) and even tried a different fuel pump.No luck. Several people have said it doesn't appear to be the injectors, to me it appears to be starving for fuel when I try to get going, but what do I know? Any suggestions? I even tried Heet in the tank(bad gas?).
It can be either bad gas smell the gas if it smell like tekila or alochol, that means the fuel is contaminated with e-85
or if fuel smells ok, check also your last receipt for last fuel purchase and make sure you have not buy any e-85, also check for maf or map sensor and unplug it, if any changes the sensor is bad, also if you have dual fuel thank check the filter in the fuel separator, it is a big plastic hosing where all the fuel lines atached together.
