Question about 1997 Chevrolet Tahoe
I'm assuming the starter rotates the engine, but it will not run. I'm also assuming the fuel pump works (new) and there's fuel in the tank. In that case, there are a few high failure parts that could cause the truck to not start. Some of these parts will make the computer throw codes, some of them won't.
First is the fuel pump relay. It should be under the hood in the power panel with other identical relays that control the horn, headlights and such. It will be a rectangular one, not square like an ice cube. Easy way to check: swap with another one in the panel and check the other thing (I use the horn). If the other thing works before and after the switch, the relay was good.
Next is the ignition control module. It is inside the distributor, under the cap and rotor you changed already. These have a tendency to make no spark as well as prevent the fuel pump from working when they go bad. I would rather go to a junkyard and get a used Delco ICM than buy a new knock-off, the off-brands just don't live long. Get a genuine GM part. You can pull your old one and they will test it at the auto parts store for free. Make sure they let it heat up for a few minutes if you do have it tested.

Check if starter has power by arcing solenoid, it may be the ignition switch or wire

Hello I would think if you replaced all those components, It would lead me to say its the ignition module, Or Pickup coil, they are both located under the distributor Cap. Fairly Easy to change should take about 15 to 30 minutes depending on you mechanical ability. I sure hope that Helps you out. If not get back and we can do somemore trouble shooting, For spark,fuel pressure. Ect.. Thanks Hopefully that will get you going.

More than likely it's the distributor. They have a tendency to build up corrosion and rust and have personally went through the same situation three weeks ago on a suburban. Check to see if you are getting spark from the distributor first. Have the ecm in the distributor checked at Oriellys for free. It's under the rotor and has two 8mm head bolts with wires plugged in at each end.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

The best way to help find the problem, is to have a fuel pressure test done on it, that will tell if the fuel pump is weak, or the fuel pressure regulator is malfunctioning. If the pressure is low, the fuel pump is weak,
if it is high, the fuel regulator is at fault.
