won't start after engine cooler
its a 2003 ford f350 6.0... has a super chips flashpaq programmer..
truck was hard to start before i brought it inside the shop(long time turning over plus missing once started)
so i just replaced the engine oil cooler got it all put back together go to crank it up and it won't start at all
turns over but won't start... i undid the fuel lines and bled them off thinking that was it, didn't help..
used starting fluid to see if that would help but still wouldn't start... im kinda scratching my head on this.. i have no idea what it could be... any help on this?
very much thanks appreciated
