truck wouldn't run when warmed up. checked fuel pressure...OK, than Looked at the ICP, oil on the plug replaced the sensor and wire, only to still have the same problem. I changed the oil and the IPR Orings... nope. I bought a new IPR... still doin it! injector Orings were next, got better throttle response, but still dying when warm. crap must be my HPOP while I'm waiting for Terminator to rebuild my pump my buddy wrecks his 7.3 powered Van, so I swap injectors with him(they had been replaced) new Orings again instal HPOP now it doesn't die when warm just has no power.
control pressure at idle is a little less than 500 and cant go over 800 duty cycle hits 60 at anything past part throttle... and pop goes the check engine light.

any thoughts on this? what can I do next? I'm almost out of ideas!
