Maybe the coolant temp sensor is bad causing to flood your cylinders.

solenoid*. sorry i cant help but that erk'ed me.

I don't know if you profile is up to date but do you have an AFPR to manage that walbro 255 you installed?

 

[93boostedtalon]

Nope sure dnt actually I bought a shell swaped motor and tranny over and the shell had a walboro in it

 

[Chill Kill Kult]

Is it one cylinder or all? Do the plug(s) come out soaked in fuel?

 

[dsmfa9nutter]

Despite what a few misinformed people will say, a 255 WILL overrun the stock fpr and cause you to run rich. My fuel pressure jumped by 10psi just by going from a stock pump to a 255. Luckily I was smart and listened to what the real tuners said and had an afpr so I could dial it back down. Put in a new cts while you're at it.

Check your coolant temp sensor and get an AFPR. That 255 is over running your fuel pressure regulator.

Well thats what I figured my check engine light is on but I think it is because I have two evac lines plug off intill I get this fixed. Just wanted to make sure it wasn't knocking or anything serious. But somone told me I coulf use a oaoer clip and look at the haynes manual and it would tell me the codes. Somonr said it could be my knock sensor or mass air. because it had been changed to a 2g plug but I didn't have a 2g maf. Or because I don't have no exhaust after the cat because the last owner off my old dsm tightend the bolts in the flange where it goes over the rearend. So tigbt the hulk could't have broke it lose and on top of doing that he stripes it all to hell. So I had to get some bolt gripers and it broke thr bolts and the car won.t run right for me to get it to an exhaust shop so yeah but thank you guys for your help and does any one think any of these could be the problem or if your almost sure it's the fuel pump.

You have dsmlink do you have your fuel pump set to kick on when the key is turned to the on position prior to cranking?

If you have DSMlink post a log or even if this car doesn't some kind of log will get you a lot more help if everyone can see what's actually going on then guessing off the little bit of info you provided... .

This is a freinds car I built for him and it does not have a dsm link. And what more info could i.give you guys to help?

 

[MY1GDSM]

A Log... Like I just said above... . You don't have to have dsm/ecmlink to see what's going on

Coolant temp sensor or your coilpack could be bad
