NO carb on this engine it's fuel injected fuel pump is BAD or the fuel pump relay...If you want to check the theory of the relay, unplug it and bridge 30 and 87 on the fuse box. If the pump is running, you might just have a bad relay. FUEL TANKS Probably full of Crude too.

I can't fund the power distribution box

My 91 Sonoma, 2.5 l( I gues) wont work on idle . Hi rpm i perfect???
