So I have had this truck since may. It started giving me problems in the morning driving to work. missing, cutting out, and sometimes would quit. The way home from work it would run fine. Then it started running so horrible that I couldn't drive it. No check engine light even. Put new plugs, cap, rotor, fuel filter, and air filter. Ran good for a day then back to running bad. U could mess with the maf and it would run a little better and you could get it to start by partial plugging it. So put a new one on. then wouldn't run at all. Now it wasn't getting fuel pressure. Put a new fuel pump in and now it has pressure but also a check engine light and still wont run. No power and the diagnostic port either. I was checking where I was getting power and cycled the key and the light was off, fired right up and ran fine, turned if off and it wouldn't start again. Anyone have these problems? Thanks in advance
