There is a red and a black on the IPR... black goes to ground, red goes to positive.
You will get 1800-2000 PSI with the ICP sensor unpluged when cranking. That is the default values in the PCM. Plug back in the ICP sensor and see what it says when cranking then. Also look for ICP duty cycle.
What software are you using to scan it?
If you can run a buzz test that would help as well.

i havechecked the fuses they are all good. i have a jump box and a charger hooked to it. the icp reaches 2300 with it plugged in but it bounces between 1800 and 2300. i remember seeing something with the injector duty cycle but idk know if it was icp duty cycle or ipr duty cycle. when cranking i can hear a fairly loud clicking that is rythmic so im assuming its the injectors firing. when cranking a little bit of white smoke creeps out of the pipe. im using autotap software its fairly good i cann read more with it than with the advance auto scan tool. alot more. im leaning more towards i have a leak on the pressure side but idk bc the fuel pump has plenty of pressure to the filter, but if i spray ether in it will start and stall.

When cranking is the Tach moving at all? Could be as symple as a CPS right now, if your making 1800-2000psi there is no reason it should not fire.
Crank and watch the tach, it should be moving on a 2000, if not the CPS is bad.

ok so i will share my ignorance. Of course after listening and learning from the great minds on db i realized i was building good oil pressure and of course the fuel system was building pressure, and that would be great if it was only fuel....not water. made the common mistake and i trusted the gauge saying it had fuel. i went back to basics like i do on the cummins and mercedes diesels. you never know what a jackass will put in the tank. check the fuel and found it was water he got it out of a storage tank that had sat for quite some time and thought that was a good idea, but failed to mention this. he had also previously painted the cluster black to cover the water in fuel light bc it was broken, ( he didnt know how to drain the water off ). thanks for all the info i learned alot guys.
