Sled won't start!!!

[T24]

I have a 2009 M8 with an Aero 53 turbo kit on it. Sled was running 2 weeks ago then was taken out of a garage and put in a shed and the next day it wouldn't start. It was -25ish so I thought maybe it had frozen up. It has since been put back into a heated garage and now still won't start. When I pull it over my head lights light up, but I have no fuel pressure, and when I pull it there are air bubbles in the fuel line coming out of the regulator. If I put gas in a spark plug hole it fires instantly then dies. Anybody have any suggestions?

hook up a remote power source to the fuel pump, if you get pressure your not getting juice to it if you have juice and no pressure your regulator or pump is out.

hook up a 9 volt battery to the pump and see what the fuel pressure does

What sort of fuel system is this one running, intank pump or external?

Well found the problem, my heatsoak switch was tripped. Thanks for the help

Put a bigger heat exchanger under the back tunnel and you won't need that dumb heatsoak switch. Go to Van Ambergs web site and they have different models. I put on the big double U exchanger and no more starting issues. Now i can make as many pulls as i want come down shut it off and one pull i'm running again. Last year i was ready to put a match to it and this year it's a totally new machine.

Bigger U-cooler

You still will need the switch even with the bigger cooler. I have one.
