ICP pressure high active code. Long start times. Remove Power puck code and problem goes away. Called yesterday and left message with tech and phone number. But got no response.

I am having this same problem. 2000 Freightliner FL50. Cranks 3 to 5 times longer & truck has no power with power puck and SES light. Runs fine without puck and no SES light.

are either of you running a tuner stacked with the puck?
