You need to check and make sure you have fuel pressure, then check for spark at ignition, if those check out then check for pulse width at the injectors. That basically is the electrical signal which tells injectors to spray fuel. Use what is called a Noid light on injector pulse width check. that will eliminate all possibilities other than internal issues with engine. I.E. broken cam, broken timing components, obviously if all I mentioned checks out then run compression test. Good Luck

Have you checked the fuel pressure? There are two different fuel pumps for this vehicle and if you installed the wrong one, for the 4.3 VIN Z instead of the pump for the 4.3 VIN W, Which it sounds like you have a VIN W, It won't start. Also I've seen the harness go bad in the intake that runs the injector. Have you checked for injection pulse at the plug to the injector.

I have a chevy blazer 94 S10 still quit on the road.


How is it running before it quits onyou. This could be the culprit of an egr valve. How many miles on thevehicle. The egr seems to die on a certain mileage pattern. Also youcould start by cleaning the egr valve before replacing it. This couldvery well help the situation, but this is just a guess. Hope thishelps!!

Not cranking


If the engine is locked up try pulling spark plugs to see if radiator fluid is inside. If so the intake plenum would need replacing as well as an oil change.
