Gary Lewis Posted February 5, 2019 Share Posted February 5, 2019 My first guess would be the injectors are stuck shut. Same thing happened to the engine I've been driving for the past 30 years when I got it from a JY, and to another I fixed & sold to a friend 8 years ago. Click each of these & read the captions: https://supermotors.net/getfile/1132417/thumbnail/30pump.jpg https://supermotors.net/getfile/825934/thumbnail/fuelpressuregauge.jpg https://supermotors.net/getfile/72354/thumbnail/doorsticker.jpg If you have no fuel pressure, the tanks & fuel pumps probably need to be replaced, as the links in that first caption show. If you have fuel pressure, but no fuel during cranking... Look closely at the injectors whose connectors are easy-to-see. Each will have 2 wires: a Red, and another wire. 4 will have the same "other" color, and 4 will a second - these are the injector "banks". Stab a stickpin through the "other" wire for one bank, turn the key to RUN, and ground the stickpin (against the intake manifold, for example). If it's really quiet, you should hear each of the 4 injectors "click" open within a minute. If they're really gummy, it can take longer for them to get warm enough to melt the goo, and 10 years is a LONG time. Once you hear them open, unground the pin, and jumper the FP relay to keep the pump running (making pressure) while you BRIEFLY ground the pin again. This washes most of the goo out of the injectors, but it DUMPS gas into the cylinders, so don't ground the pin for more than a second with the pump running. Repeat for the other bank of injectors, and remove the pin. Then the engine should start & run "normally". I'd put SEVERAL cans of Berryman's B-12 pour-in into the tank. That's a slick trick!

Steve83 Posted February 5, 2019 Share Posted February 5, 2019 That's a slick trick! It also worked on another friend's '88 C1500 5.7L TBI a few weeks ago. Link to comment Share on other sites More sharing options...
