Hey everybody. I typed this long drawn out thread, but I'm on my phone and it decided to delete it all when I hit submit, so he's a shorter version. I just bought this sled for $500 and thought it just needed a new battery. I was wrong. The previous owner replaced all the fuel lines, filter, pump, and spark plugs, as well as gave me another good fuel pump and 2 extra ecm's. It would run on ether but died as soon as it all burned up. I replaced the battery, same thing. I decided to plug in a different ecm. The fuel pump started running and i realized that it wasn't before. Still won't start. After about an hour of tinkering I found fuel to the rail with good pressure, but the injectors weren't firing. I tried the third ecm, and got no fuel pump or injector click. Plugged the first back in and got injector click but no fuel pump. I started it and it ran for about 30 seconds and died, would start for a second or 2 and die again after that. Plug the second back in, fuel pump runs, plug the first back in and start it, runs for 30 seconds and dies. I opened the thirm ecm to look inside and found that it has no chip. My thinking is that all 3 are bad so i ordered a new one. I then decided to ground the pink wire and manually make the fuel pump run with ecm number 1 to see if it would run then, but now it wont run at all, not even with ether. Did I flood it or did i mess something else up? Also, do you agree that the ecm is the issue? Thank you everybody in advance
