1997 5.7 Vortec won't start.

[Tripp]

OK guys. I'm gonna need some help here. I parked my Tahoe last night and I went to start her up today at 2:30pm, and she wouldn't start.

I have power, the radio, power windows and lights all turn on at full power at the same time.

The starter motor fires great, no issues with that.

But the engine isn't turning over. I'm guessing something is wrong with the fuel system...

The fuel pump primes. But maybe it's too weak? I replaced the fuel filter back in April after I bought the truck. Maybe injectors?

I just changed the oil last Friday. All the fluids are good. The ignition was replaced from distributor to spark plugs a few months ago.

Any ideas guys?

If the engine isn't turning over it's a starter/battery problem.

Is the motor acting like it wants to start or is it just clicking?

Maybe my words were incorrect. The engine turns over. It's not clicking. The starter works. The battery works. It just won't actually fire up.

Bump...Any ideas?

One of my customers at work told me it might be a crankshaft or camshaft position sensor. Perhaps...

Entirely possible I've seen it lots of times

Any other ideas, before I start throwing parts at it?

Crank position sensor... Cheap and easy to replace.... Many ruin a starter before they figure it out.. Starters come with a hang tag warning you about a bad sensor

Before you throw parts at it at all... Pull a plug and check for spark. If no, let's figure out why, if yes, let's check for fuel at the rail..

There's a method to this madness
