P1765 (M) Trans 12 Volt Supply Relay CTRL Circuit An open or shorted condition is detected in the Transmission Relay control circuit. This relay supplies power to the TCC.
P1765 (M) Trans 12 Volt Supply Relay CTRL Circuit Current state of solenoid output port is different than expected (4-speed auto. Trans. Only).
P0753 (M) Transmission 3-4 Shift Soleniod/Transmission Relay Circuits An open or shorted circuit detected in the overdrive solenoid control circuit or trans relay circuit in JTEC RE transmissions . Was MIL code 45.
P0753 (M) Transmission 3-4 Shift Soleniod/Transmission Relay Circuits An open or shorted condition detected in the transmission 2-4 shift solenoid circuit (4-speed auto. Trans. Only).

well i would say you probably havent hooked up everything to the trans yet which is what those codes are for. You probably have your firing order wrong, it's easy to do. make sure you have pressure to the fuel rail.

Well, I replaced the distributor and rotor. No go, my friend had something similar happen, but when you fire it up it takes a bit than goes, but idles really sloppy, and when you have gas it will go but jump up and down, back fires at about 1000 rpm. So Not sure what is going on...

I haven't hooked everything just yet, but the engine will run without the tranny....

what about the TPS sensor and all that stuff, are all your vacuum lines hooked up? that would cause it not to run.

Well, I cleaned the sensor it all seemed okay maybe il do a quick swap on the TPS from the v6. The vacuum lines are all hooked up.

Il go try that.

Swapped the one from the 3.9 no difference at all.. Any ideas? TPS, IAC and MAP have all been cleaned/checked, I might just got buy a new set of wires tomorrow, see what happens

varsis once again, have you MADE SURE that the plug wires are hooked up right? have you pulled the plugs and looked at them?

Yes, I checked all the plugs, wires, rotor and cap.

I have put them on like 5 times, checked them double checked and tripple. I am thinking maybe a faulty wire... I will go buy new ones in the morning I am getting stumped...

I wouldn't buy new wires without checking the resistance on the current ones. Unless one of the wires is over 50k ohms, they're probably fine. What is the firing order on a 5.9L, and which direction does the distributor turn? Did you set the distributor with the engine at #1 TDC? It sounds an awful lot like a timing/firing order problem.

yes that is what im thinking too. if you dont have a haynes manual for your truck, i strongly reccommend you get one. it has everything you need to know like the firing order, how to fix major timing problems etc.

if you dont have one, i can go out in the garage and get mine, it should have specs for a 5.9 in it. ask me the questions and i'll try to answer them for you. that manual has saved my *** many times.

Well, The rotor doesn't matter when you change it. It won't spin unless you turn the actual engine as that is timed by the cam/chain. I am guessing a wire. The rotor is on properly. I might try and move the wires one over. Maybe the 1 on the dist is off a bit?
