I had a shop hook it up to a machine but it gave no codes. I don't have a machine. Is there any other way to pull codes without one. I can't afford to keep taking it in.
yes I did this and got a code P 0700
Yes that was the only code and the 8th number is XXXXX 6
Does this require a special tool ? After I've been able to get it started it runs like a new truck. Would this be the case if the lift pump was not pushing 10 PSI
The guy I'm working with has a fuel pressure gauge but we have not been able to find a shcrader valve. Can you tell me where this is located?
There is no schrader valve there and could not find one. This problem does not always occur on a cold start. Even when the truck has been run and turned off it will not restart. Could this be a pressure regulator valve on the fuel rail? I replaced the original fuel pump at 130,000 miles. I got about 60,000 miles on the replacement pump. I then replaced the pump again with a heavy duty fuel pump from Cummins and thats why I didn't think that it could be the fuel pump because I've only gone a total of 60,000 miles on this heavy duty fuel pump.
This is a common rail The Vin # XXXXX XXXXX and it has a presure regulator on it.
I guess what im going to do is replace the pressure regulator first, if that doesnt do it then i will have to plug each injector one at a time to see if one is sticking open. If I find one that is sticking do you recommend replacing them all or just the one? If I do replace one or all do you recommend new or remanufactured. In your experience If one goes bad do the rest soon follow?
