Oil pressure switch or ignition module should solve your problem. If not, check the fuel pump itself, relay, filter, etc.

off a cliff and enjoy the explosion. I have the same model year and I have nothing but problems I have changed all of the same above and all that happens is another problem comes up. It stalls smells like rotten eggs EGR clogs up clean that out SES light comes on again truck runs like sh!t again. Put on code reader shows EGR clean and replace again day later damn thing is up to no good again. Now this thing is starting to act like my ex-wife and does what it wants when it wants and does a crappy job at it. I think GM made a real lemon of a vehicle of the 1994 4.3 Blazer and mine only has 91k on it. Well if anyone wants to join me for marshmellows I will be cooking them at the bottom of some cliff over my burning Blazer

What about a cat convertor or O2 sensor?

Does the exhaust sound growly when you tromp on the gas.

no sounds good it will just cut off like you shut the key off and then you give it a little gass and it takes off again

Aha!

Yes, I bet you have a shot CPI fuel injection unit.

You will have to take off your upper plenum and check for washing.

Here is my experience with the CPI and Nut Kit replacement.

*WARNING* Do NOT let this go for much longer. The fuel pressure regulator on the side of the CPI unit is leaking and probably spraying gas all over the place inside the plenum. This gas goes into your oil, dilutes it and could cause serious engine failure.

I AM GOING TO OPEN IT UP AGAIN BUT I HAVE JUST REPLACED THE INJECTOR KIT AND NUT KIT IN FEB.

Before you do that, try swapping out the coil.
