my 1989 f150 pu wont run but about a min
my 1989 f150 pu wont run but about a min and then dies . wont start unless you let it set for about a hour. when this started it was running ok then started sputtering and loosing power when you gave it gas ,also quit a few times on me . now it will only run for a min or two then dies . please someone help me out. has two fuel tanks . and a fuel pump under drivers side cab.
Have you checked for spark when it quits running? Does the engine have a low oil pressure shut down switch that turn off the fuel pump if there is no oil pressure, Have you changed the EEC and fuel pump relays?
