i have a 7.3 03 powerstroke it would'nt start a couple weeks ago. i changed the gpr
and it seemed to help, drove it for fore days and it started missing, now it wont start.
i checked all the connters, the conector for the hpo seemed to have oil in it sprayed it with ether to clean it out still wont start, it has a yellow cps, while cranking engine over with scan tool easyscan 5000 it shows engine 350 rpm but no timing advance or ipr 0% no ipc
any thoughts thanks

 

Unplug the ICP sensor and try again. The computer will default to stored settings.

Check the HPO res and make sure there is oil in there, should be about 1/4-1/2 below the top.

DO NOT start off ether.

 

ok thanks for the reply !!!!! were is the hpo res ?

 

red arrow is pointing to an aftermarket oil pressure sender, but on your truck there will be a plug there. Remove that plug and check and see where the oil level is. Do this first thing before cranking on it in the morning. It should be very near the top of the lid.

 

Check the basics as well, fuel filter maybe the truck is low on oil. If you have a problem Joe can usually fix it!

 

ok the hpo res is 1 inch below the top of res !! the icp is the three wire connector
in the front driverside head on the 7.3 ??? oil in engine is full,will change fuel filter for good measure! have to change starter monday as i fried it !! thanks again for all the help

 

where is the ICP sensor on the 1999 7.3?

 

Blue arrow is the ICP sensor...

 

Thank you. I will have to try that on mine too. I am up for ideas on how to fix it. I going to try to add some mods to it but i am scared to do anything with these problems...

 

ok changed the starter, cranking the engine over it would try to start then stall, pulled the icp plug it was full of oil, cleaned it with eather pluged it back in and it started, ran ruff for about ten min then cleared up, drove it about one block and it started missing
barly made it back, it seems like a fuel issue no smoke out the tailpipe that i could see
old filter had a lot off black stuff running out of it when i sprayed it with cleaner, but i
didnot see any rust chunks could the icp cause this ? or was it just a fluk it started when it did ? ps thanks for all you people
