I put the pressure tester on there yesterday and it wouldn't read anything for about 5 seconds of cranking and then it would build to 20psi, then it would fire right up and jump to where it should be. I checked the IPR valve and replaced it with a new one so there is no doubt that it could be the problem. The ICP sensor has also been replaced. But, once I turn the truck off, the pressure on the gauge drops to zero in a couple seconds. I will get you exact readings tonight.
