'95 Dodge Ram 1500 4x4 auto 5.9 liter Tran slipped badly once warmed up. Changed Trans. Now the truck will not start. Starter spins engine properly. No fuel in fuel rail. Checked fuelpump relay and it is good. I bypassed the fuel pump relay and the fuel pump worked properly. It has fuel pressure in fuel rail only when I bypass the fuel pump relay. It will not start even with fuel pressure in the rail. I plugged into the computer test plug and got and connection error. I adjusted plug several times and got the same error message with the key off or on. Power goes to the fuel pump relay from battery and ignition switch. I've rechecked the wiring harness and am sure that I have plugged in all of the wires that I unplugged.
