I have recently aquired a 1994 GMC Sonoma extended cab 4x4 with the v6 Vortec engine. Everything worked fine until one morning when it didn't want to start up. It cranked and cranked until it finally fired up, but it sounded rough. I pulled off the air filter and had a friend turn the key, and gas just started pouring out of the injectors, and I mean just a ton of gas. This flooded the engine to the point where it could not get enough spark to start. I am totally stumped as I have tried the gasoline formula cleaner stuff from autozone, and later replaced many parts trying to get it going again. Here is a list of what I have replaced thus far:
MAP sensor
Throttle Position Sensor
O2 sensor
The computer
throttle cable
both injectors
-and a couple of other odds and ends on the fuel system that I can not recall at the moment.
I have read that there were recalls on the fuel pump and sensors, but I have hit a wall and don't know where to go from here... ANY AND ALL suggestions would be helpful!!! thanks!
