Ford E-550 Engine problems by year

started to break down the engine to find what was wrong. They thought that the injectors after being taken out and tested were not in that good of condition and that they were the cause of the problem and should be changed. We had them change 7 of 8 injectors also called glow plugs. This came to about $4000 same problem different state truck went to new dealer ship was told nothing wrong with it. Picked it up and drove it and of course it stalled on the road again it was towed in and they said it had to be wiring and since it would take to long to look over all the wiring and with the symptoms the wires were bad so we needed a new wiring harness. We had them put it in. This was about $ 2700 we picked up the truck and truck stalled on the highway and was not off the road this time, we had it towed back to the dealership again. They again said they had no idea what was wrong with the truck but it must be wiring so the wiring coming out of the fuse box, was changed not sure what the name is now. About $900 truck was serviced again in another state at another dealership about 4000 another state and truck was in dealership again. They found problems with the glow plugs, and we were told first dealership was at fault. $1900 Back home again and truck is still stalling so I looked up on web truck not starting and stalling and this came up. I cannot not tell you upset we are at this we are out 13,500 and it may have been a bad cps we are bankrupt. *Tr
