Question about 2003 GMC Sierra 1500
2003 5.3L 4x4 GMC Sierra has started being hard to start, cold or hot, mileage 130,000. You can turn the key on and the starter keeps spinning after you have released the key, this happens even when yyou try several times. Usuaslly on the third or fourth try the truck will start. Runs fine after it starts. Changed fuel filter and pressure regulator, still does it. No codes showing.
Sounds like a Solenoid might be bad on the starter if it spins freely and a high rate of speed without engaging.
Also, the relay could be bad.
I am ot sure if the fuel filter and pressure regulator would cause this problem.
No code will show with a bad starter or bad relay, I don't believe.
Good luck with this one.
