Default Odd fuel issue after compression test? Won't start

Car: '98 LGT 2.5, T04E turbo w/ sti injectors, EManage Ultimate

Problem: turns over but wont start. This is the first time Ive EVER had this problem.

First thing I did yesterday was remove an old Vortech FMU which I no olnger need since I've been running EMU fr about a month. I simply removed the lines and placed all the vacuum lines back closed to the boost gauge and sealed all the fuel and vacuum lines back together.

Next, I took off my intake and washer bottle to do a compression test, after I was done I put everything back together. Compression test went fine, took the car for a test drive and everything was peachy.

THEN, I took off my intercooler (06 WRX TMIC) and intake to recheck and reseal the entire intake system, I knew I had some boost leaks and think I solved all the issues with those, a few loose spots later and I think I'm good to go. Then I put everything back together and go to fire up the car. Turns over, no joy. What could have possibly happened between taking off the intake and intercooler. Im pretty sure this is a fuel issue, I clamped the fuel line to see if it was flooding and the car fires for a brief moment. Why is the car flooding now?

The batteries been disconnected all night and I could really use some ideas.

Step 1: Post in the right forum
Step 2: ?????
Step 3: Profit!

are you sure you plugged everything back in correctly? Did you mix up your coil packs?

Well, Im certain that I caused this by removing intake/TMIC and screwed something up in the process.

I think next step Ill unhook the EMU and plug the car in as though it were N/A and see if the EMU or my wiring did this.

It just seems too coincidental that I took some **** apart, put said **** back together and now it's flooding. I must have done something wrong while I was in there.

Are you still using the stock MAF sensor or an aftermarket MAP sensor? Check to make sure it's plugged in...

I'd also highly suspect the ignition system before anything else electronic, if everything was plugged in beforehand.

Have you verified that you're getting spark?

And how bad is it flooding? I don't mean to sound like an ass, but is there any way you hooked up a vapor return line to a vacuum line, so it's just dumping fuel in? I am not sure how many fuel/vacuum lines you had hooked up to the old FMU...

Just an in and out on the old FMU.

Getting spark, verified.

Stock MAF sensor, I also have an old WRX sensor Ive been messing with too. But shouldnt the car run for at least a few seconds with a bad maf, or just run but like ****?
