1988 FSB, 351W, Towing Package
This is a topic I’ve seen posted around the internet, but suggestions vary wildly. Looking at the truck 2 weeks ago before I bought it, it started and ran fine (and supposedly has for years as a daily) but while looking at it it quit wanting to start at all. The guy replaced the fuel pump relay and it went back to starting and running fine, so I bought it. 2 weeks later, I’m in my driveway with it after driving around and it dies on me when I get off the throttle. It would start but would die if it wasn’t throttled. I was floored, but remembered the fella replaced that relay so I made sure the connection was tight and Jiggled it around and low and behold she cranked right up and ran well for another week. Well, yesterday it began the same thing, it’ll start up but die after a couple seconds. Before the guy replaced the fuel pump relay, it wouldn’t try and start, I’m not sure if these are related. I’ve read about bad ford grounds and such, but I’m not sure where to start. I can hear the fuel pump come on when turning the key on. All else I’ve done is disconnect the negative terminal for a couple minutes to see if the computer would sort itself out. Can anybody help?
