Ok here's the deal

Truck is cranking longer then normal for start up, hot or cold dont matter..quite a bit longer then normal, so I did some digging around and checking things out

batteries are fine cranks fast has new starter fuel filter is new, oil is clean garage is 70 degrees not a cold start issue.. I was reading to check icp and ipr.. well I pulled the connector off the icp and its wet with oil, I started it with the icp unplugged it seems to start better and it dont have the stumble as soon as it starts. I used brake cleaner to clean it out blew it dry with the blow gun plugged it back in seemed to help but still not right.. I never made it to the ipr as I was hoping I found the issue

It's safe to say the icp is screwed and is likely the issue? will it start as good with it unplugged as it would with a good icp? or will a new icp make it start better then not having one hooked up at all...

well .. I dont know what to say I figured Id have a few opinions ..

anyway I ordered one today Im goin to try it .. I hooked it to the snap on scanner at work and watched the icp as I cranked it, it didn't move at all for the motors first 6 or 7 revolutions then it went it did go up it went up real slow .. I checked the hpop its about 3/4 of a inch from the top so I know its not low on oil up there even after it sits all night its not bleeding down

I figured since there was oil in the plug even if this dont fix the hard start it wont have oil in the plug anymore with a new icp

well if anyone has a long crank issue like I did the icp fixed the problem... fires up so easy now less then 1/2 the crank time as before and idles smoother right up off the start up

I must say I was amazed not one person had any info for me on this .. truly a first, I ALWAYS find the answers to problems here..

for a moment I thought I was invisible:hehe::hehe::hehe:

ICP - Injection Control Pressure sensor its on the top front of the left head between the alternator and the lifting hook to yank the motor

i have the same problem i was just fixing to ask if it was suppose to be like this... after you changed it did it run any better or did it just make it start easier???

thanks

starts way way faster and runs better for sure smoother idles better

it seems to have better throttle response and power too..

Thanks for posting this up!!!! I have been chasing my long crank issue. New IPRs, New hpop(Termy), new injectors, turbo. Ever since install, cranks are like you said- 5-7 turns(4-5 seconds). Gonna just a have a looky at my sensor.:nod: IF you still have the IH part number, can you post it up or pm it to me. I got a dealer an hour from me. Thanks!:thumb:

here ya go.. the parts guy @ IH said its common issue and if the plug has any oil in it at all its bad, if there is no oil it could be just slow to send signal of oil pressure.. my truck runs soooo much better now

International) (94/95) 1830669C92

(International) (96-up) 1807329C92 <<<< ---- this was the one for mine if you pull yours out the part number on it will be one of the above numbers but it wont have the C92 that is a updated part number that was added to the original number .. use a 5/8 stubby wrench to get old one out new one will go in with a 1 1/16 socket new style :thumb:

no one is more glad then me.. cranking like that makes the truck look like a pos that dont wanna start and its hard on the batteries and starter

Just checked. Mine is clean, and dry as can be. No trace of oil. My long starts are intermittant. Some times will crank as soon as key is turned, other times- loonnnngg crank. I have had the connector pigtail replaced at the dealership also. Oh well, just keep pluggin away till it shows itself. Thanks again for the info.

try starting it with the icp unplugged... the computer will go into default pressure setting

if it starts better unplugged the icp is lazy..

so its no better unplugged .. dont know what to tell ya have they had it on the scanner while trying to start it ?

I have Auto Enginuity, and I watch ICP while cranking, and it builds fast ONCE it starts building pressure. It just takes longer to start building pressure sometimes. I almost want to say its a side affect of the modified hpop. Just a guess from me though.

mine was scanned on start up too the thing cranked a good few seconds before the pressure was up high enough to start ..after it started the pressure was normal.. remember the reading you are seeing is from the icp if its slow to read it will not start right away .. now it cranks a couple revolutions and the pressure is up real fast and fires quick..

do you know anyone who has one you can try .. I wouldnt rule it out yet

mine did the same sat at 0 for a little but then it moved quick .. try it out its easy with a 5/8 stubby wrench if nothing more you can totally rule it out then.. let me know how it works out
