replaced injectors now truck doesnt run WTF need help asap!!!!
so start off, fathers truck was running like ****, very weak on power as in would barely move out of its own way. had 4 fault code for injectors. Cleared them and they all came back. truck has around 225k. The truck would still start and run even with the injectors going crazy.
Now replaced those 4 injectors on the passenger side bank and put all of the used injectors on the drivers side bank. Try and try to start truck nothing. Then after a while it would run like ****, but better then it did before and was semi drivable. (for about 2 miles). Came back and had a code in one of the old injectors that was swapped over to the driver side bank. Cleared code and it came back.
Then hooked up a fuel pressure gauge to the truck and noticed that after the truck would get fired up and run for a few seconds it would drop all fuel pressure. It got so bad that it would not even have enough fuel pressure to start.
So next thing we replaced was the fuel pump. Put a new oem ford updated fuel pump on the truck with the new pig tail etc.
Truck still did the same thing run about 20 seconds die, now this time it would bring up 2 injector codes. Decided to go ahead and replace the 4 injectors on the driver side bank.
Now seems the truck is no different at all and takes forever to crank but when it does run it will run for about 20 seconds once again and then die. It has done this for a repeated amount of times and now there are no codes (using a mac scan tool)
We have replaced all filters, all 8 injectors, valve covers, full of oil,glow plugs, fuel pump
This thing is driving me nuts. I do not understand how the hell the truck is running when it gets put into the shop and now after replacing all of this stuff it will not even stay running at all. And when it does run it doesnt run that great.
Again when it starts up, watch the fuel pressure gauge and it will just start to loose fuel pressure and then cut off. I am not familiar with the 6.0's and the 2 mechanics who are working on it are both Detroit and cat mechanics and this is there first 6.0 as well.
we are all banging are heads agaisnt the wall as this is very frustrating.
btw the truck is bone stock
any help would be greatly appreciated asap
