99 Silverado 1500 4x4 cranks won't start, Im at a loss

Asked by Steve Sep 10, 2020 at 11:33 PM about the 1999 Chevrolet Silverado 1500 Extended Cab 4WD

Question type: Maintenance & Repair

99 Silverado 1500, has 170k miles, been parked a long
time. Cranks but won't start. I put in a new fuel pump, new
fuel filter, new fuel pressure regulator. All fuses and relays
are good. Fuel pressure is reading about 50 psi and holds
for 10 mins. New plugs and wires, and all plugs show a
spark. Just checked compression on all cylinders, and
they're all showing 150 psi. Tried security reset and that
didn't work either.

Any ideas on what yall think it could be or what else I could
try?

Anti theft isn't on, new fuel filfer and i have good fuel pressure, im getting sparks on all plugs, and i just replaced the crankshaft sensor - still won't start.

If anyone ever reads this or cares, it ended up being the cam shift position sensor. Showed no codes, but started up after swapping it.
