Question type: Maintenance & Repair

Have problems with starting my truck. Turns over OK and anti theft looks OK. Sometimes runs fine others nothing. I know its fuel related. Checked the cutoff switch under the passenger side and it's OK. Only other thing I can think of is it may be some fuel pump modulator above the spare tire. Anyway to check this. No code lights coming on fuse looks good. Don't believe its' the pump as sometimes it starts and runs great. Any suggestions would help.

another good thing to check is the fuel filter usually it could be a problem most times it will work or it wont with that if not try to look at a ignition problem
