Distributors are very tricky and must be installed perfectly. It sounds like you may have installed it incorrectly or the distributor could be broken. How I fixed a mistiming issue on a Jeep with a distributor was I loosely bolted the distributor onto the engine and kept turning the key. The car wouldn't start but it kept cranking because the distributor was not even plugged into the engine. What will happen is that when everything lines up the distributor will drop on its own into the sequence and the car will start. At that time you can turn the car off and tighten it down. That's what I did a couple years ago with the Jeep and she's still running perfect today. There's many other much more difficult ways to do this, but this is the quickest way I found and it worked. It took a few tries but was all worth it in the end. Hope this helps!

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

On a 99 Tahoe Don't remove the grill.. There are two 6 inch long, hex head, vertical screws protruding from the frame above the headlight. To unscrew use a small hex socket.. maybe 1/4 inch. Turn the screws counterclockwise to remove till loose then pull up. The screws serve as a linch pin to secure the headlight to the mounting bracket. Here's a pic of the driver side light. Also, I had very good results with my park light lenses in 5 minutes with a hand drill, a soft buffing pad, and some fine polish. They were yellow and dull and looked clear and white when done. I washed the inside of the lense with soapy water and a soft toothbrush.. it made a big difference.

check the crank sensor. no signal from the crank sensor causes a no spark condition. best way to check is to put a scanner on and check for rpms.
the crank sensor is differnt from the cam sensor

i had similar problem. hard to start in morning but once started, would start everytime until next morning. i changed fuel pump, filter, fuel pressure regulator, coil, cap, rotor, pickup coil, battery. i was finally told the '96 had a recall on the fuel injection assemby. i changed that out with the new mpf system and it solved the problem. runs like a striped ape. hope this helps.
