Help! Flooded, won't start.

I installed a procharger, started my car on the stock tune, and flooded my engine. The fuel pump works, the engine cranks, but does not start. I'm 90% sure that it's flooded. I tried taking the fuel pump fuse out and cranking the engine, didn't help. What do you suggest that I do to get the car to start? It's a 2008 GT. I'm trying to avoid taking the plugs out, it seems to be a little bit of a challenge. I've never changed spark plugs. Any advice will help! I need my car to run ASAP.

I had to move the car and had no other choice.

Doesn't pro charger include a tune?

Yes they do, but I hadn't received the time from them yet.

Yes, I have it now, but it still won't start. I just replaced the spark plugs, and it still won't start.

What did the engine do when you first started it? Did it run normally until you turned it off? Did you drive it any distance or just move it? Did it just die? I know the manual for my roush supercharger states Do not start the car until the computer has been programmed it can cause catastrophic damage. I'm not saying that's what happened to you and I hope not, but it is a big no no. Hopefully it's just something simple and a quick fix.

The engine started and rev'd at 1500, then after a few seconds started dropping, like a cold start. The only thing was that it didn't stop dropping RPM's until it died. And the day before, I had the car idling for a minute or two just fine. I was just checking to make sure everything was installed correctly, considering that the procharger doesn't produce any boost until around 3000rpm, and the car did the same thing with the 1500 RPM's, then dropped to a steady 800 rpm. The only difference the second time was that it didn't stop dropping, and now it won't start. It acts as if it is flooded, after sitting for a good 9 hours, it tried to start, but didn't. Changed the spark plugs, they looked like crap. It tried to start again, but didn't. I'm hoping that after sitting another day with new spark plugs, it will start.

Maybe it's not getting gas? Inside passenger side, front under the dash, remove a panel. Inside you will find a "box" on top will be a button you can push in, it will reset your fuel pump.. Just push that down and see if it works..

I'll definitely give that a shot. I have a fuel pressure gauge, and it reads 0.6 psi when I'm cranking the car. When I took the fuel pump fuse out of the fuse box, it stayed at 0.0 I wasn't sure if that was how much fuel pressure is needed to start the car, or if it was messed up.

Tried resetting the fuel pump, didn't work. Again, the car almost tried starting, but then wouldn't start and the second try wasn't close to starting at all. Maybe if I just let the car sit a few days without trying to start it, it will dry out and start?

The starter is fine. I just pulled the injectors out but left them all connected and cranked the motor and nothing came out of the injectors. Fuel pump problem??

Not sure how much they are. I had to install a new one though to go with the procharger. What doesn't make sense to me is that when I took the injector out, fuel poured out with it. Not a lot, but some did.

Can you hear the pump when you turn the switch on with out cranking? Checked the pump fuse? also check for the connector for the pump in the trunk if you can't hear the pump

When I turn the key on I can hear some humming around where my pump is and it stops humming after a few seconds. I'm pretty sure I hooked everything up correctly when I installed the new pump. I'm thinking maybe either the relay for the pump that's in the fuse box, or it's something with the injectors. What is that you were talking about in the trunk?

If I take out the injecors, but leave them all hooked up, when I crank the engine, nothing comes out. I then took them out of the fuel rail and fuel was behind them. I drained all the fuel out of the fuel rail. I then re-installed all the injectors on both sides and tried starting the car. The car started and ran at 600rpms for about 5 seconds then slowly dropped rpm's until it died. I drained the fuel rails again, and the car did the same thing as the first time. I don't think it's bad injectors considering that I drove the car home with them. Idk what it could be! I want to be able to drive my car so badly!!

I've cycled the key and looked for leaks. I'm probably just going to take the fuel pump out and take a look at it.

Help! Flooded, won't start.

Since you can hear it your connector is in place and fine in the trunk.

I'm not a fuel pump wizard but mine makes a whine sound when I prime it. Like "eeeeeee". It doesn't make a "hum" sound.

Yeah, that's a better description. Mine also makes that kind of noise. Do you think maybe it has something to do with the MAF sensor?

Ok so the fuel pump sounds to be working fine but it's not making its way to the injectors?

If it was the MAF I'm pretty sure you would get a check engine since that is an electrical sensor and not mechanical.

My check engine light flashes then stays on, but when I check for codes it says there is no fault. I don't know much about MAF sensors. Could it be pegged or dirty? I wish I knew someone else around here with a stang so I could just swap out the MAF and see if that fixes it.
