ICP Pressure Reads Zero for a couple minutes
I have noticed recently that occasionally my ICP pressure will read zero for a few minutes when I start my truck. The problem is intermittent, so I cannot predict when it will happen nor can I use my scanner to verify that the problem is with the ICP and not my gauges. I have a 3x pillar gauge system, with the ICP measured through an HPOP pressure gauge (reads directly off the ICP) from ISSPRO. The only possibly issues I have noticed with the truck are a slight decrease in power, also occasionally, but not necessarily with the "zero ICP pressure" symptom.
1997 F250 4x4
Mods that have been done to the truck: 3" turbo back exhaust, Tymar intake, TS-6 Chip, EVPB Switch as exhaust brake, 1.0AR turbine housing, HPOP line crossover
New parts on the truck since the last year: fuel pump, fuel filter, IPR valve, belts, all fluids with SCA, all filters, All fuses checked, batteries, starter, battery cables to come. (just listing everything for completeness).
If anyone has had this problem before with varying power, please let me know. I plan to take out my chip and double check the connections. I just find it strange that this problem is intermittent if it is an electrical problem through a connection since the connectors are so light and probably don't move. The chip is also taped down. Any help is much appreciated.
