Hey All new member here.
I live these gm400t trucks so I will save one when I can. I purchased av1998 k3500 4x4 crew cab with no motor and no wiring harness. I then picked up an engine and harness from a 98 k2500 ext cab.
I installed it and can't get the truck to run
If I spray the intake she will fire but I get no power to the original fuel pump harness left on the truck and is running up to the firewall. New harness seems to have a 4 plug square running to the back of truck with orange,grey,purple,black wires orange is D and hot I do not get 2 sec prime power from any other wires I'm lost.. also I'm using the original 3500 ecu and if I jump the relay u can hear pump but sounds like the intake is just pouring gas in it I don't know what to do next. Any help would be appreciated
