nope. Literally let car sit a bit ( was a bit hairy in the snow ), started it up, swapped garages, came back to it and nothing...

 

Check your fuse box in the engine, check if fuse #15 is working. If you dont have a way to check get some replacements at Walmart for $4 and swap it. I had the same problem yesterday cause some idiot put a wire instead of the fuse in the box. Its worth a shot to check it out. There's a diagram under the box cover to tell you which one #15 is btw.

Mine did the same thing yesterday and I thought it was the pump too.

 

checked all the fuses inside under the steering wheel and under the hood... all looked good.

 

If you still haven't solved if the Walbro is working or not you can turn it on in Evoscan. You could also then remove the return side near the fuel rail and run it into a bucket and run it again.

 

have you pulled your plugs?

i bet the cold start was never really tuned and you fouled your plugs, so now everytime you try to start it your just fouling your plugs

see who tuned it and see if they can help you out and start with a fresh set of plugs

 

Ouh... good call. I'll check that out..

 

To test for fuel I unbolt the feed line from the rail or use evoscan. You can test all your injectors also. To test for spark pull a plug wire and put a screwdriver in the cylinder. Could be your tune also. My V7 wasn't set right so it took 4 separate cranking "sessions" to start my car. Fuse 1 is the main one under the dash that would cause that exact issue. Just replace it if you haven't. Did you pull every fuse?

 

You look at a fuse and if the element is there the fuse is good....Not always so. The element (the wire that vaporizes when the fuse blows) may also crack or come unsoldered. The fuse will look good but be open. Just replace all the fuses associated with ignition.

 

just an update for anyone else with the issue... GOT IT RUNNING!

Swapped to some new (read: cheap) plugs, cranked over and hit first time. Let it run, get warm, drove it around a little (pretty cold here). Stopped, swapped back to the iridiums, it hesitated first turn, but second hit, started right over.

I'm guessing the fuel WAS frozen, and i somehow just fouled the plugs so badly, that it wouldn't start at all... Anything after that just made them worse. Pulled them out, and yeah, they were black... but not super bad at all. So yeah, check your plugs.
