if this is the vortec engine you may want to check to confirm that the injector pot is working. The injector pot is located under the air intake manifold (top half only) & PLEASE BE SURE TO DISCONECT BATTERY FIRST. if you unbolt the top half of the intake manifold you will find the main injector pot otherwise known as the SPIDER. This part does have a history of failing and can be very costly to replace if you purchase it new. most junk yards should be able to find one for you.

Try using a good fuel line/injector cleaner Seafoam is a good one. If this does not help you may have tone or more clogged injectors. Clean these out and you should be good to go. tTo see Seafoam in action goto you tube type Seafoam into the search box.

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.

Make sure battery has a full charge. If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
If you have tbi fuel injection, fuel pressure is 9--13 psi.
If you have cmfi fuel injection, my info says 55--61 psi.

Make sure you are getting power to the injectors. I have the same,350 tbi. Check the fuses and relays and check the wires at the tbi to make sure one of them is not rubbed through. The injectors have to be getting intermitent power .

GM TBI low voltage at the injectors


sounds like a computer issue on the burb, but i would check the IAC(idle air control) valve and the TPS(throttle position sensor) first.
I would start with the IAC on the 93'.

You will need to get up there Right above the Throttle Body and hold a Good Maglight or LED Flashlight above the TBI and have Someone Crank it Over. You will see the Spray inside the Bowls if it is Getting to the TBI.
