Question

My Car has seem to be starting hard it is on e85 dose e85 start hard when it is could. it has been like 20degs or so out lately since I got the car back together

when it starts it dose not turn over very fast. but after about 10 cranks it will start. now once or twice when I went to start it it cranked over pretty fast about twice as fast as it did before but it has only did that like two times I tested pin 108 with my volt meter and it is only getting 7.5v or so wile cranking is that right or should it get 12v. I attached a log of it cranking is the key start signal normal

Thanks
MJP

Have you checked how many amps you are getting while cranking? A slow cranking motor could 100% be caused by your battery not giving enough juice.

Also, try letting it sit overnight, and hooking up jumper cables. See if it starts right away then. If it does, you know you have a battery issue.
