1988 CHEVROLET BLAZER

:( allright here I go: 88 chevy blazer 4x4 with throttle body. My friend brought me her blazer with no spark. I replaced that problem which was her control modular. The truck would fire then die after a few seconds. A friend decided to pour some gas in to prime it. Ya that really helped well the thing backfired and caught fire. Luckly no major damage just some vacuum lines. I replaced those no problem. Well now the thing isnt getting ANY Fuel. I tore into the throttle body cleaned it replaced all gaskets checked all three relays & wires everything looks great. But no fuel. There is fuel to the throttle body with great pressure but no discharge from the injectors. Is it the injectors or possibly the fuel pump? I am out of solutions. PLEASE HELP!

I am guessing that if you had a fire under the hood you most likely melted the throttle body, it is only aluminum, or melted something in the body, especially if you have fuel up to the throttle body. Your pump is working if you have gas that far. The throttle bodies should be a dime a dozen at any junk yard, they were used for a lot of years. Good luck!

Sounds like the Injectors are not pulsing-Try cranking it while keeping a close eye on the injectors-No spray find out why. Maybe the driver in the PCM or Wire
