Hi ALl:
usually pretty good at these things but at a bit of a loss on this one.
1991 F150 w a Multi-port EFI 300 6cyl 5speed 2wd.
ran & drove OK in Aug, (only use it for TRUCK needs) so it sets when not TRUCKING something.
went to start it up cranks good battery good. has spark/fire. both in-tank fuel pumps run fine.
SO started troubleshooting.
1 checked for fire, put in line spark plug checker & it has light/spark
2. sprayed a bit of ether into it and it fired up and staid running but no power, so replace fuel filter as I had one.
3. still same issues, dont have a good way to put in-line fuel pressure tester on it YET (making trip for one this weekend.)
SO pulled the Fuel Pressure Regulator, $40 bucks later still same issue... Pulled and cleaned all the plugs (carbon buildup running rich & has been)
NOW I'm not sure what next to look at? Any suggestions>???
thanks all
Mark
