Question about 1991 GMC S-15 Jimmy
What can I dow?
Where is the spider and fuel pump relay located on 1991 gmc jimmy 4x4

A very common failure on these is the CPFI unit , or SPIDER as people like to call it.
There is one single injector which feeds each cylinder via a pipe and poppet. The injector becomes blocked and the engine won't start or run.
Before you go condemning this though, just make sure you have good fuel pressure because the fuel pressure regulator or fuel pump could also have a hand in the problem. Make sure the pump is running, and if not then check the fuse, the relay, and the pump itself.
Very best regards
