by the way it appears to already have a new pump on it but not quite for sure fuel lines dont appear to be right to me

 

It is possible that a couple lines did get crossed, but not likely. Could also be an IP timing issue. Look and see if any fuel is being returned from the pump. On the front there is a hose. Remove it and see if any fuel comes out. If not, run a jumper from the fuel shutoff and see if it helps.

 

pulled the line off the top of the ip and some fuel did come out. the return lines that run from injector to injector are the ones that dont look rite. campared to my 7.3 they dont run the same where they cross the back of the block there is a 4way t onew line runs to the pump one down the back of the engineand then one to each injector on back 2 cylinders. the right front injector has a t on it but seems to be pluged no furl comes out. i dont know if i explained good enough it just dosnt look rite. is there a way for a novice to check the ip timeing? and thanks for the reply wildbill

 

Looking at my dads 6.2, the back two injectors have a plug, then a line daisy chaining the rest of the injectors. Then on the front two, there is a hose that connects to a steel line that runs to the return to the pump, then down to the line to the tank.

 

thanx wildbill i was trying to compare it to my 7.3 but it looks alot diferent. may be Im just expecting to much out of it. it seems to run fine just dosnt seem to have the snap that my 93 does. Ill just run like its is till i can do somting diferrent thanks for your help.
