My 98 gsx won't start

[Yiddie]

Drove it to my work. Noticed a vacuum line off my intake manifold, also fixed my pcv breather. Started it up, Idled high and was running really rich turned it off, started it back up doing same thing, so I took off the vacuum line didn't do anything put it back in then sounded like it was gonna die. turned off my car and now it won't start at all. I sprayed carb cleaner in the intake, it tries to start bout it. I'm getting spark and fuel also.

I have 950cc inj. and 255 walbro pump and some other mods, Tuned on e85 also.

Any suggestions?

Is she still cranking but not start up? Also did u physically see spark when u removed the plug and held it near a known good ground and see her arc?

Just an idea, Remove the intake boot and place something inline to keep the throttle valve open a little. Air her out and I would even goes as far as to pull the plugs and check em'. With huge injectors like that and adding carb cleaner I would imagine like any other engine it can still get flooded. So my idea is air her out for a bit and see if she fires up. I have not posted for a long time so my experience with DSM's is a little rusty but my diesel experince can still be of assistance. If u pull the plugs and they are wet along side with ## rich condition......and the smell of fuel it could possibly be flooded. Again I know I am rusty at this so forgive me if I am of no help.

Yesterday, I determined it was a fuel issue cause I could cut off the return line from my fuel rail and it would try to start. also we had the car running straight off carb cleaner, but I checked fuel pressure and it seems fine. I tested pressure off my pump and after my filter.

But i'll give what you said a shot. Thanks I appreciate it.
