'98 305 vortec died, getting fuel to motor but no start

[Jorge6.5]

Went to pull out on the road and my truck died. I went to restart but it would just turn over. I listened for the fuel pump and heard nothing. I replaced the fuel pump/sending unit, (sending unit was already bad). I also replaced the fuel filter. Getting fuel to the intake manifold and truck will run briefly off starting fluid.

That's about as far as I got. At a loss of what to try next. Could it be the fuel spider? Not real familiar with the vortec engines.

Thanks

What's your fuel pressure?

Is your check engine light on?...

Not sure of fuel pressure, what should it be? No check engine light, I should probably hook up the code reader to check for codes.

Key on, engine off, it should be 60psi or better. Engine running, at least 55psi. Deadhead the pump and it should hit 80 to 100 psi.

I just went through the exact thing you described. I ended up replacing the ignition wiring harness that comes out and down the steering column. $100 for the part and about 1-2 hours of your time. You will most likely need special anti-theft torx long shaft sockets, which I found at Advance Auto.
By the way, you will never get a CEL from this issue. No scanner will pick it up either.
This is a common GM problem as the switch wears out from you turning the key thousands of times. The security system shuts off fuel, but not crank or spark. Good luck.

crank position sensor on front of the motor

Turns out it was just the ground wire from frame to fuel pump. Put in new ground and works great now. Also added an optima red top battery. Turns over quick now.

Hope you have better luck with Optima than I have in the past few years...

What happened with yours? I always thought they had a good reputation, 2 friends of mine have been running them trouble free.
