I run the car on E85 most of the time and when I try to start it, it will stumble and won't start......Turn the key again and it fires up every time. When I put 93 in the tank the car runs and starts like a beaut. Any ideas what to check for?

I run a second pump attached to a hobbs switch.

On first start that's one of the drawbacks to E85... shouldn't be that bad in summer months.

Pretty sure this can be addressed in the tune as well.

Mine does it the same whether its hot or cold outside. Heat index was 100 degrees today.

Then it would be a tune issue. I believe there are cranking tables to tweak.
