Hey, i've been having problems with my JRSC, more specifically something with the fuel system.

The shop that has my car has removed the JR EMS and the JR Fuel pressure regulator. The car idles relatively well, and after idling the car for hours and turning it off, the engine will flood, and wont start. I'm thinking that residual fuel pressure in the rail is being released into the cylinders after the car is shut off, but is that enough to flood the engine? I have the walbro (sp?) pump installed, stock injectors, AEM CAI, the blower is still attached, but like i said before, the EMS and FPU have been removed. The engine was flooding with or without the EMS and FPU, so what else could it be? Is there anything else is hould be looking at before swapping back in the stock fuel pump (keeping in mind that i never had a flooding problem before i replaced the head)

Will adjusting the valves (there is a fair amount of valve tapping) fix this problem? Thanks in advance!

 

So did you put your stock FPR back on? Or your not using one at all? That doesnt sound right.

 

well the stock regulator is used in conjuction with the JR one, the stock regulator is used for the idle fuel pressure, the JR one is supposed to be tuned for boosting... but to keep things simple... yes, the stock pressure regulator is being used right now
