Hi my name is***** will be glad to try to help...Try this procedure to retrieve your codes. check to see if the tach is responding while cranking as a failed cam sensor is a very common cause of this. click below and let me know what you get for codes.

the tac is working while cranking and there is 40 psi oil press

Thanks for the update. With the ICP sensor unplugged the ecm should go to default settings and see if it starts. should be around 870 psi at the ICP sensor port with a 5000 PSI guage in the ICP sensor port while cranking and up to over 4000 PSI with 12V at the IPR while cranking. Pressure test with shop air at the ICP sensot port to listen for air leaks under the valve cover indicating injector o ring leaks. Let me know

Verify ECM power and grounds and also check the IDM relay and wiring harness.
