1991 f150 dual tanks starts sometimes and runs well but turn it off and sometimes wont start otherr times is reliable
Getting no fuel pressure but sometimes it starts when it does it doesnt die and runs well
but shut it off and it doesnt want to start.
Fuel Pressure Regulator not putting out what it needs. so you will need to replace it
Thanks but it was the tank selector switch gone bad. Fouled me up for three days the guy I bought it from thought the truck was done so I got it for a steal!!!!!!!!
