Help flooded the motor and gas is leaking everywhere!

[Rebel79]

To give you a quick run down of events... last week I was rearended and my intank pump shut off. All I had to do was bang on the fuel tank to get it going again and it was fine after that except for my fuel pressure would not raise under boost. This happend to me once before and my FMU was clogged. So to help torubleshoot the possibility of a bad fuel pump I took apart my FMU and cleaned it.

Once I put everything back together I turned the key to on and the fuel pressure shot up past 100psi! I did it a couple other times and the same thing happend. Once the pump primed, the fuel pressure stayed at 60psi. I started the car, but it died within 2-3 seconds. I could not start it after that. I noticed a strong smell of gas coming from the motor and saw a puddle of gas from underneath my car. Evidently gas was coming out of my IAB in my intake. I took off the hose connecting my blower to my throttle body and it was wet with gas. I opened my throttle plate and about half a gallon worth of gas poured out! I pulled my plugs and some of them were fouled so I am gunna replace them all anyways.

I checked my oil and no gas leaked into the oil pan, thank god. What shoud I do next? I was thinking of trying to start the car without the vacuum on my FMU or FPR to see if that helps any. BTW there was gas in the vacuum lines, especially when I pulled the line off of my Fuel Pressure Regulator (which is a 1 year old Kirban).

Anybody heard of this happening?

Any chance your fuel return line could have been pinched or kinked?

Other than that I would have to think your regulator is not working.

Its possible I screwed up the FMU when I rebuilt it. I put everything back together and left the vacuum off of the FMU and FPR and primed the pump. A 3-4' stream of fuel spewed from the FPR. Needless to say the FPR blew an internal gasket or o-ring, possibly do to the FMU.
