1994 gmc sierra k1500 issues

I have this truck I cannot figure out why it is not running. It gets spark and fuel and the engine will turn over but it will not start. I thought it was the crankshaft position sensor but I couldn't find it on the vehicle. So I bought a book and low and behold... It has neither a crankshaft nor a camshaft position sensor. I'm trying to get it running again to sell it as I have pretty much given up on it. A little bit of help would be much appreciated!

Re: 1994 gmc sierra k1500 issues

It may be a fuel supply system problem. Although you said there is fuel, there may still be other problems with the fuel supply system, such as fuel pump, fuel injector nozzle blockage, etc. I suggest checking the status of each component of the fuel supply system.

There are only a few things required - Fuel, spark, compression, and all at the proper time.

Is there spark AT THE PLUGS?

Good catch. I hadn't even noticed the date of the original posting.
