E85 now wont start

[hellssephiroth]

Ok. So, running chrome, just put 750cc injectors in, drained tank and put e85 in.

I set the voltages for the injectors and set the size to 525 for the extra 30%. Car won't start. Did I forget something? Not even getting a sputter.

Hmm did I have to up the fuel pressure for RC750's compared to stock?

575 is what you should start with (750/1.3).

If the car won't even cough it is something mechanical/electrical. The tune can be ridiculously off and it will still try to run.

Actually you probably have residual gasoline in your lines so it probably flooded the engine. Unhook your fuel lines and drain them (crank for a second or two) then try again

post your original pump scaling values.

My PTE/Rochester 1000's are scaled at 745 on 93 and 590 with e85. What were your fuel trims before you switched to e85?

When I switched to e85, I literally just pulled in, pumped 6 gallons of e85, rescaled and she started right up no problems at all. I held the gas for like 20 seconds after initially starting to run out the pump as quickly as possible but it started right up.

Everything fuel tuning was just whatever stock was i didn't touch anything in those areas.

Wouldn't the residual gas just overflow back into the tank?

Here is my fuel/air system, 3.75gm maf/maft blow through, dual wallys hotwired, 750 injectors, 3sx fuel rails, 6 or 8an fuel lines dont remember fuelab fpr, stainless filter. I think thats everything.

yeah it will, but the car will run momentarily really rich while the pump gas is still in the injectors. Mine took maybe 10 seconds to clear up. Like posted above you may just have fouled the plugs. clean the front 3 and see if it hits.
