Hi Nir,

My friend uses a seven cell battery too. I don't think that 2 volts will push enough juice through the pump to make your engine run properly.

Make sure the battery pack is freshly charged and that you have at least 8.6 volts available for a good strart.

I'll ask my friend to pass on his settings to me for reference.

Are located in T.A.? Temps must be as high as here in Nicosia this time of the year.

Good luck,
Chris
