Engine Mechanical problem
1995 GMC Sonoma 6 cyl Four Wheel Drive Manual
I hooked up noid lights to my 4.3 TBI injector connectors and I'm not getting anything on either one of them. I know the noid light is working because I checked it against another TBI engine. I don't understand what this means.
I'm sure that it's I'm not getting power to the injectors but I can't figure out why. I have a fuse [ECM IGN 20amp] that keeps blowing but even when the fuse isn't blown and the key is turned I'm still not getting any light.
I don't know if it makes a difference but I just replaced my fuel pump and I'm sure that it's working (i can hear it) but I can't figure out where to hook up my fuel pressure gauge to check pressure. I've heard between the inlet line and the throttle body but that would mean splicing into the metal line. As far as I can tell there are no flexible fuel hoses anywhere within the engine compartment or aft of the fuel filter.
