ICP Queston

So, i know a diagnosis for ICP issues is to unplug the sensor. from what ive observed, this is for people who can get their truck to start. the truck defaults to 700 psi or whatever and they then assess their problem.

if the ICP is unplugged before starting the truck will it start at all? i know it will default but cranking psi is lower than the default psi.

that is my question, keep reading if you wish...

im wondering if something is up with my icp. AE didnt get a reading from it f a long while, then it was down in the 290 - 360 psi range. and i know i need 450 minimum to start. at one point it read 2226 psi for one second. it read 0 for a long time before any of this. now at the time the AE capture was taken my batts were a bit low and crank was slowing. and that may be why the ICP read low. my truck will start now if i crank forever and wait for the oil pressure to rise (dash gauge). but im woderning if im losing my ICP. i have a buddy i can swap with but wanted to know if the truck would even start if the ICP is unplugged. cause ive tried it and it wont. but i already have an unknown issue. im worried my hpop is having a drainaback problem, i really hope its not.

Only thing I can contribute is, yes a truck will start with ICP unplugged. Mine has while chasing down ICP/IPR/IDM problems.

I'm still having problems with it, just don't have time to mess with it until finals are over. Mine has random shutdowns when it's hot. Happened to me twice on the same road, it acts just like you turned off the key, with no restart until it's cold. Let me tell ya wrasslin' 7k is fun w/o power steering and brakes. And the 4 mile walk, lol.
