So i just bought my first electronic injected diesel. Guy said he couldn’t get it started. Thought lift pump was bad, installed a raptor lift pump (in the stock location on the drivers side of the block?) looks like there is new quick disconnect lines between the raptor pump and the VP44 but he used the stock lines between the tank and the Raptor. Is this normal?
So anyways. After properly bleeding the fuel system, resetting the APPS, and trying to do some trial and elimination; The truck won’t even start with the lift pump on. Disconnected the power and it fires right up and idles smooth, but will sputter when reved like it’s starving for fuel. Reconnect power back to the Raptor pump and the truck immediately starts to miss and almost dies. Kill power to it, it smooths out in about 20 seconds.
Tried adjusting the loressure screw all the way in and out. No difference. The tank gauge is on Full. But i know these go bad. I’m going to grab 5 gallons of diesel and put the suction line right into it to fully rule out air leaks.
Anyone else have some ideas?
Thanks.
