On my extended cab, the front passenger seat will not slide all the way back to the lock position

There's probably something in the way. Get under and behind the seat with a flashlight and check the back end of the rails to see if something is there.

Dash will not display shifter position or mileage

It actually sounds like you have a cold or cracked solder joint or you have oxidation on your connector or socket to the display module. Unplug then plug in your display module several times to attempt to remove the oxidation and see if that helps.

I have a 1996 gmc

Possibly a busted fuel pressure regulator diaphragm. The regulator is mounted to the end of the fuel rail. With the engine idling, pull the vacuum line off the regulator port. If gas comes out of the port, replace the regulator. 0996b43f80219b2e-sulc2cgngkoxge0rocse0fez-1-0.gif

Took my 1996 gmc sierra 5,7 to get a oil change,,

They make oil pan plugs for this situation. It's a bolt with a rubber spacer that expands to seal the hole when you tighten it. If the old plug is still in the pan, use vice grips to thread it out. No need to replace pan, but maybe replace the oil change shop. Guys you went to have no experience.

96 sierra 4x4 5.7, no spark, no fuel, only have .4 volts at ingition module, coil, and 10A ign fuse. Door locks don't engage when turn key,

Something wrong in the fuse box if you only have .4 volts at the fuse. Maybe a loose terminal in there.

1994 Sierra C/K 1500.

The lock cylinder is the most likely suspect and is in stock at your favorite local auto parts store. To change it, the steering wheel has to come off first. The lock cylinder is held in place by one screw. If there are more problems, you will see them when the steering wheel comes off.

1997 gmc sierra 3500 won't start

When you turn the ignition to start, do you hear the starter turning and the solenoid engaging the flywheel ? test your starter by jumping it and see if the engine turns over. If this works, then you might consider in checking fuel pressure. Do you have any codes in your ECM ?
