Hi, my friend just his turbo installed on his 00 civic with b18c swap.

He upgraded to a walbro fuel pump, fuel rail, ignitions, regulator except his injectors. It is still stock. Everytime he goes to pump gas. He turns on the ignition the car barely gets to idle and shuts off. It only happens right after he pumps gas. Anybody have any ideas on where should he be looking for?

ahh i too have the same problem....only after i did my b18c swap it started to happend but then after i boosted it got even more harder to start the car after i pump gas...i know some guys who have this same problem after a motor swap but i got use to it cranking it 3-4 times just to start her up...bump for answers

Try unplugging the evap purge control solenoid in the engine bay.

Man this **** is driving me nuts!!!! the cars drives perfect, passes emissions but shuts off right after pumping gas in it. I could have a full tank and put 25cents in it and it shuts off wtf!!!

after filling the car full? if so, the charcoal canister has gas in it, when the purge solenoid is supposed to be allowing gas vapor, it is instead allowing raw gas into the intake manifold. Try unplugging the vapor line from the purge solenoid to the intake manifold to see if it is wet.

That sounds so right! I'm going to try it tomorrow tx..

I tried it and it was dry..

I've repaired a car with issue by replacing the gas cap. The cap wouldn't allow the system to build full set pressure after it was removed. I figured it out because of a TSB on the Chrysler 300m...they had that issue, and their gas cap was at fault.

How this relates to those that just did swaps is, you likely have pressure releases in the system. It won't cause a leakage of fuel (well, sometimes it will), but it makes it more difficult for the system to pressurize after opening the tank.

I'd replace the cap (cheap), then just tighten and check all the fuel system connections you broke when doing your swap or installing your setup. Replace any o-rings (injectors, fpr seat, etc).

Also, for any of you that just installed a fuel pump. The rubber gasket around where you access the fuel tank could be crimped or the plate improperly torqued. That will cause a small pressure bleed that takes the tank a minute or two to recover.

Either way, the problem is linked directly to a loss of pressure in the tank via some means.

read again...I made clarifications for some people. The cap was only cited as a source to pinpoint the issue.

Re-read my post.

The fact that you breached every aspect of your fuel system, confirms that that's what is creating the problem.

Sorry about that I only read the 1st sentence for some reason!
I'll check all of this now! tx

I finally fixed it!!!! I upgraded to a walbro 255 and up the pressure to where it needed to be 47-54 without vacumn and it started right up @ the pump!!!!! Damn it feels good...

haha. damn that was a hard one.
i had some guy come in with the same problem but i had no idea what it could be
