1991 ALL OTHER MAKES ALL OTHER MODELS

I have a trooper v6 2.8l. 5sp. I can only get it to start for about 20 seconds. I check computer codes and not any. It seems to be getting to much gas @ injecters. I have to unplug them to get it to start again after flooding. It orginally just stopped at intesection and had a wire melt to knock sensor module. Had wire replaced. And replaced module. Thought it was the problem. Also with all other items happening I thought maybe ecm was not good. I unplugged some items to see if code would read. I can get a map code but no throttle position code. When unplugged. It has good fuel pressure. Spark. Timing. I would like some input before I spend more time and money. Can you help?

Let me try to get you on the right track. You smelled fuel earlier(dangerous situation) and engine ran terrible. "Smell" goes away and engine ran fine. Now engine won't run and you replaced the fuel pump. You don't hear pump whining when you try to start the car. If the pump is in the tank and it is full of gas then you might not hear it. Instead of listening, why don't you just carefully loosen the fuel connection at the fuel filter and then turn the ignition on to the start position and see if fuel is coming out. Now you know if problem is fuel or someting else. Check for spark. Check for broken timing belt etc. Let me know what you find.

Please don't do this in the order the Captain prescribes or possibly we will see you in heaven some day. Even though there might be fuel coming out, get the vehicle fuel system pressure checked. Find out how much pressure is there. Next you can address the spark if this does not help.
