Too much fuel on startup

[myRed240]

I tried to start my car the other day and all I got was sputtering and fuel spitting out of the exhaust side of turbo. I pulled the plugs and they were soaked in gas. Tried several times to no avail.

Went back to inspect the injectors, so I pulled the fuel pump fuse, removed gas cap and then cranked it to relieve fuel pressure. To my amazement it fired up. It ran like crap but it stayed on. I turned it off, replaced the fuse and tried to crank it up, but it wouldn't-same symptoms as before. Removed the fuse again and it started again. WTF?

I know that it's getting fuel, in fact I believe it's getting too much.I've inspected the injectors and the O-rings look good as new.

Here's what I've added to my car:

NGK BKR7E plugs (at first gapped to .033, now at .042)Z32 fuel filterEnthalpy ECU tuned for:New Walbro 255 fuel pumpNew DW 555cc injectorsZ32 MAF

This is all on a 95 240sx with original motor (27k miles) that ran like a champ before this. The car has not seen boost yet....

Thanks for any help.

Your injectors are too big..

You need a fuel pressure regulator that will limit fuel.

I had the same problem before, the reason it works when you remove the fuse is because the fuel is not being shoved into the cylinders, but the injectors are pulling it through slowly..

Ok, so even though the ecu is tuned for them I still need a FPR?I was hoping I didn't, but if that will fix this headache, then I guess that's what I have to do...Thanks!
