Scott, you'll really appreciate this. OK, there's a friend of mine who somehow has conned me into letting me keep his car at my shop while he builds it. It's a generic 89ish nissan 240sx that we built a little engine for and he's bolting on a t3/t4 turbo and running it with MSv3. It's been slow coming along, especially since he moved to Knoxville a few months ago and just comes out about every other weekend to work on it. Yesterday was going to be the day of truth when he fired it.
key on.
fan turns on
fuel pump turns on
a few seconds later gasoline starts dripping out of the throttle body (we had the turbo inlet hose disconnected for the moment)
key off
open the throttle blade and gas POURS out of the intake.
We look inside and the intake is COMPLETELY full of gas. I mean solid gas all the way down and filling up the cylinders!!!
"how do I get it out?" he asks
I tell him there are two options; he can pull the manifolds to drain them and siphon the gas from the cylinders or just pull the spark plugs and crank it over.
The spark plugs go in from the top of the engine on this particular unit. Has anyone seen the fountain show at the Bellagio? Picture that but with gasoline now. I swear to God that gas shot up more than 25 feet in the air in four perfect streams! It was dripping from the roof of my shop! Totally hilarious. And a mess to clean up.
He's trying to figure out what happened and why the injectors were held open. I can't figure out why. At a quick glance he has keyed 12v constant to one side of all the injectors and two injectors hooked to green and two to brown on the MS wiring harness from DIYautotune which is supposed to ground it. I guess it must be issuing a constant ground instead of cycling it. I let him use my stimulator to check things out and hopefully it will be running (and out of my shop) today.
