2005 f150 king ranch Triton 5.4L 3v
I bought this truck because it needed a transmission and seemed like a good deal. Replaced transmission. Drove it to gas station and it started running rough at idle. Eventually running more and more rough until I barely made it home. So it ran okay until I put gas in it/ drove it 5 miles. Not sure if it was the gas that was the issue I drained and replaced it. Not better. Now I have replaced..... Injectors, tps, maf, fuel filter. No place to check fuel pressure except for scanner. It shows 41psi. It does not have enough power to move. Idles pretty smooth but can't even pull it up the driveway. I cut the cats off as a last hope to see if it would move tonight. And still nothing. I will put them back on tomorrow I guess. Replaced all the coils and spark plugs and computer and engine harness now as well. I suppose the last thing is a fuel pump. I will PayPal someone money if they can even point me in the right direction.

 

I would pay for help. I want to take it to a mechanic but could only spend $1000 if any more than this I can't afford it at the moment.

 

Are there any noises rattles ticking etc. Could be phasers etc.

 

I will replace those today. I'm tired of this thing. No noises, just no power.
