08 6.4L no start when hot

hhrecovery · Jul 22, 2015

08 6.4L has 220K on truck but engine has been replaced... New HPFP, and injectors have been sent of and tested and bad ones replaced w/ new injectors... Truck starts and runs great... After you drive it about 20-30 miles it will not start until it cools down for 20-30 mins... Only throws a low icp sensor while cranking code...

Check main low pressure fuel pressure at the fuel cooler.
