Flooding?

Flooding?
OK for those of you who know me. I had a SC in my car (will be back in very soon) with the Walbro fuel pump.
I pulled everything out of the car for some warranty work except for the Walbro.
Now I have a brand new engine and the car floods when you crank it.
To the point that 1 out of 3 times I have to pull the fuel pump fuse crank the car a few times until it starts and then put the fuse back in and the car will start just fine (after I crank it again).
I floods so badly sometimes that I can smell the fuel inside the cab of the car.
Has anyone else had this problem?
What do you think it is?
Please help I want to fix this problem befor I start the SC install.
NOTE: Fuel Pressure reg is factory

Only thing I can think of is getting a FPR to control the idle fuel pressure. Like a SARD unit. Thats odd that you are experiencing flooding. What psi does the fuel gauge show when you crack, does it go beyond 45psi? If so that is way too much then.

Well, my sending unit for the FP gauge is on the the hoses for my FMU that is not in the car. But will be as soon as I put the SC in.
I was thinking that it might be the OEM FP Regulator.

Once you get the Fuel Pressure gauge in we can check the idle fuel pressure and then the idle fuel pressure with the vacuum hose disconnected. That should bring the fuel pressure upto around 43psi from the normal of 34psi. If not, then there is something wrong with the FPR.
If so, we can check the FPR by disconnecting the vacuum line going to it, cap the end coming into the FPR, then hookup a vacuum gauge/pump to that line that goes to the FPR. Start the engine, the vacuum will read Zero in the start, as you increase the Vacuum pressure, the Fuel pressure should Decrease, if not, the FPR is bad.

Thanks. I kinda figured that the FPR is the problem but did not want to get the SC installed and have other problems to deal with. I have bought a after market FPR but did not want to buy all the fittings just to test the system when I will have to re-do the lines when I put in the FMU & SC.
I am going to try someone else factory FPR to see if that works.
