ok, for almost a year Ive had a hard start issue, It was getting worse so I started changing things.
I knew I had bad injectors..
I changed injectors, glow plugs, icp, ipr, cleaned turbo, egr deleted, RR fuel system installed, CFM large mouth SCT livewire and Innovative tuned. (all at the same time)
The truck runs great once it starts and will start right away after the inital fight. to fire the first time after more than about 8 hrs(reguardless of temp) it takes a little "help" (i call it help to save the lecture about ether....gotta do what you gotta do)
It has done this all summer, lows in the 70's and now into the 40s-50s.
I put an AE scan tool on it, all criteria good EXCEPT FICM V shows 40-42 v before start. After the initial start, it shows 46 constant and stays there.
I changed my FICM to a KNOWN good one yesterday and still get the same 42v before and during crank. give it some courage and it starts V jumps to 46-47 and stays.
every time i turn it off after the inital start, it is 46 and starts in 2 sec.wait 8-10 hrs(even in 90* days) and it wont start again.
is there a relay, or something I can check that feeds that voltage to the FICM?
Please please please help me ,
walmart is running out of ether!
