OK, I have fuel pressure 60 psi. I have 480-500 psi of icp. No start. MY snap scanner shows 0 in the desired icp block. I have never seen that and I think that is why I have a no start but what is causing that

its starts and stays running on ether?, does it see RPM?

Customer reply replied 1 year ago
it w run on ether and the scanner sees rpm while cranking
Customer reply replied 1 year ago
if I hook a separate harness to the ipr and put 12 volts to it, the icp will go to 5000 very quickly. which leeds me to believe that the pump is ok
Technician: Alex Olsen,
 replied 1 year ago

ok good yeah i would say the pump is good, so it stays running after you start it on ether?

no only till the ether runs out
Technician: Alex Olsen,
 replied 1 year ago

ok, and no codes, usually when the ecm desires no icp it dosen't think it is cranking

make sure the cam sensor and crank sensor are connected and pins are clean

Customer reply replied 1 year ago
crank sensor is working because it is reading RPMs. not sure how to check cam sensor, but no cam sensor codes
Technician: Alex Olsen,
 replied 1 year ago

yep reads rpm off crank, un plug the cam sensor and see if it sets a code
