So i have a 92 f150 with the inline six 4.9, it has a snow plow on it and mainly only use it for plowing or maybe some occasional wood hauling. Hadn't really used it all summer maybe started it here and there to move it around well a few weeks ago i went to move it and it would crank and crank and then start and run really rough and then die, would do this over and over again, if i stayed on the throttle it would stay run but would run terrible. I thought it would maybe the IAC valve so i swapped it off an old truck with the same engine and it seem to run ok after that, i ran it up to the garage and put the charger on it, the next day it did the same thing, couldn't get it to stay running on its own and with the throttle down it ran terrible. I then tried swapping the TPS sensor and Map sensor and no change, eventually after trying several things over and over again it proceeded to get worse and eventually it wouldn't run at all, just crank and crank and then i noticed the fuel pump was constantly running with just the key turned forward and not in the start position. After doing some research i found that the EEC/ECM goes bad causing a spark issue and causes the fuel pump to run constant like that with the engine off. So i pulled the EEC off and took the cover off and sure enough the capacitors were blacken at the connections and broken, so i thought great i'll get a new one and put it in and should solve the issue, well i put a new one in and the fuel pump would then cycle normally, but it still won't start, it'll crank and sometimes halfway fire but still wont' start. I'm getting very frustrated as i've already pulled the codes and nothing except an EGR fault which it has had since i got it. I completely stumped as to why something would happen so sudden and i find a problem and fix it and it still won't run. anyone have experience with the early 90's f150's?
