my truck is the 94 f150 with the 4.9L i6 well its started acting up then it just wouldnt crank...well i figured it out after all my friends kept tryin to play mechanic on it for some reason the fuel pumps wouldnt turn off after they built enough pressure so i changed out the pressure regulator and after all the hell it gave me i got it in and cranked it up well had to start it with either and it ran rough...it started idling fine and it ran well...
now my problem is this it stalls every time engine lite turns on so i need someone that at least had the same problem to let me know something plz and thankyou

 

Check the computer for codes.

 

im thinking the computer just needs to be reset though cuz it runs like a champ just when the engine lite comes on it stalls out but they dont have scanners for obd1 that reset codes

 

You don't need a scanner:
