Too hot to do much today but tried bleeding more ... there is a lot of fuel coming out at each injector but still no start. It sounds like it's not cranking fast enough, though when I put the charger on the battery it's saying it's almost fully charged ... I'll leave it on for a few hours anyway. Would it be OK to use a booster pack to see if it just needs more cranking juice?
I don't think I have air anymore but I could be wrong ... I get bubble-free fuel out of the secondary filter bolt and lines at the IP. The car was starting and running OK prior to the work ... it has probably been 2 months since I last started it and it started easily then. The only problem was the engine was rocking at idle sometimes. But it started pretty easy even when it was cold out.
strelnik, do you mean the return lines? They are relatively new, but maybe I cracked one while pulling them off the old injectors. I could try replacing those.
