Question about 1993 Chevrolet C/K 3500
The only way to know for sure on the fuel pump is to plumb in a tap for pressure. I think the range is 9.5 to 11.5 psi.

HI, You need your coolant temperture to run 195 degrees, start by replacing thermostat with correct part and re-check..

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

something is creating alot of air to pass over the 02 sensor.
Big vacuum leak.
IAC stuck a little open.
TPS that is saying your foot is on the gas when it is not.
EGR stuck open a little.
Too low an idle
Weak spark plugs
Bad fuel pressure regulator
No vacuum to the fuel pressure regulator.
Bad coolant temp sensor.
What are the readings. Need to know the co and the hc reading in order to know if you have a misfire or an over fueling issue. All 5 reading are really needed to diagnose fuel related issues sight unseen

If it is fuel injected you may have a bad fuel pressure regulator. The regulator is attached to intake manifold with a vacuum hose and the bladder sometimes fails causing gas to be dumped directly into the intake manifold. Only solution is to replace the fuel pressure regulator.
