Question about 1997 Chevrolet K1500
1997 chevy Z71, fuel pump is working, new fuel filter, all appears to be good. we have to prime the throttle body to get it to start when cold.
I just a very similar issue with my 1997 Chevy K1500. I changed all of the fuel components and the issue turned out to be the two prong thermostat sensor on the front of the engine. If your car will start by pressing the gas pedal all the way to floor then the issue most likely is the same. A code engine reading from that sensor will cause the vehicle to not shift into overdrive, degrade gas mileage, and make the truck hard to start when the engine is warm. If it isn't starting when cold check the fuel pressure at the injectors turn the key on and the pressure should go to about 65 psi and when you turn the key off the pressure should hold to about 60 psi.

Check the fuel line it may have a small hole that is allowing air in. If air is getting into the line the fuel will flow back into the tank. Happend to me one day and it turned out to be the clamp.
