truck ran poorly now won't start?
left the movies last night and the truck started up just fine but when i tried to accelerate and it just about died and the check engine light came on. I was able to nurse it home going about 10-15 mph but it would not go any faster. I plugged it in all night went out to start it this morning and it tried to start but was really rough sounding tried for about a half hour and nothing so I check the HPOP level and topped it off. checked glow plug really and it is giving good voltage. I have unplugged the ICP (or so i think, driver side valve cover toward the front) but still nothing. Since the check engine light has gone off, I do not have the tools to read codes, i have a battery charger on it right now so i have good voltage at the batteries as well.
1999.5 f250 7.3 with hypertech programmer and edge attitude both of which are off..... i have re-programmed the computer to stock still nothing.... thanks for any sugestions...... Last edited by CrawlerCraig; 12-26-2008 at 04:12 PM.

is there a way to test or do I have to start buying parts and trying them that way? If I could read the codes would they be able to tell me?

yes and no some codes will show up but for a O-ring leaking oil by no.
its always good to clean and change o-rings on ipr valve. are you using the right motor oil ?

could be your idm module or injector harness under the valve covers. will your hypertech read any codes for it?
