dkesler Posted August 12, 2013 Share Posted August 12, 2013 It has 80psi at the filter while cranking but won't start. Ether it and it fires and runs all day. Sometimes it will start the first thing in the morning but shut it off and it won't start without ether forthe rest of the day. The starter is cranking it plenty fast. My guess is it is not being told to inject fuel during the starting process. It is the gray engine and we switched computers with a 1998 E7 and the 1999 computer will start the 1998 but not vice-versa. Quote Link to comment Share on other sites More sharing options...

turckster Posted August 13, 2013 Share Posted August 13, 2013 Check the ground relay, it may be popping open when cranking the engine. This is usually cause by a bad starter pulling too much amperage or internally shorted. Had one eat my lunch doing practically the same thing when I came across the bad relay and starter. 1 Quote Link to comment Share on other sites More sharing options...
