Asked by Tylerjoyal Apr 03, 2018 at 07:47 PM about the 1998 GMC Sierra 1500 K1500 SL 4WD Extended Cab LB

Question type: Maintenance & Repair

I have a 1998 gmc with a 5.0 the truck cranks but
will not start here's what I did, i did a fuel pressure
test and got 55 psi I'm also getting spark and I did
a compression test on every cylinder and got about
180 on all but number 6 cylinder I got 105, I also
put a spider in it and it still cranks but will not start.
The truck has all brand new plugs, wires, cap,rotor,
cam and crank position sensors. I was told that it
might have jumped timing but I've never herd of a
timing chain jumped on these truck any help would
be much appreciated  thanks

I have a 98gmc as well and just a heads up if you drill your cylinder it might activate the passlock making it sound like it wants to start for 3s then turn off...
