Icp bad??

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
