Need Master Guru Expert help!
Ok. MY car wouldnt start due to a flooded engine. I just had installed a microtech LT-8 and calibrated the TPS. The car still wouldnt start. I tried everything in the book to unflood it (pulling plugs, putting in some atf, cleaning plugs turning engine, pulling egi fuse and sticking it back in, pulling fuel pump relay, etc etc etc you name it) the car still wouldnt start.
I installed the factory ecu back into the car, started right up (fuel pump relay switch was out) and left it idling for about a minute. It was idling like a charm cept a lil high because i messed with the tps before. Stupid me i shut the car off and then it wouldnt start again. For a while it would start for about 2-3 seconds then die out. I did the same routine like pulling fuel pump relay, turning engine, putting the relay back in etc etc. Eventually the car stopped trying to start and it would just turn over and over and here i am stressing because theres nothing else left to do.
**Things to consider** Earlier in the day I had my gas cap off and was trying to start it. Put the cap back in and let the car sit for about 6-7 hours which is when the car started up (when there was pressure in the fuel system) AFTER the car started and got stumbled with no starting i released all the pressure by removing the cap. I put the cap back in and tried starting it so theres pressure building over night. I will be trying steps 1-9999 again tomorrow.
So remember, the car started perfectly when i put the factory ecu back in. I cleared codes. And all i've messed with since the car started was the egi fuse, fuel pump relay, and the fuel cap. Yes this one is very complicated. Mahjik.... Rynberg..... Any help is appreciated.

Lives on the Forum
You're certain the car is flooding? Is there a lot of fuel in the motor when you pull the plugs?
If the car is flooding typically the engine will sound like it wants to start but can't quite get there. Once it runs it will be loaded with fuel so it will run rough for a few moments until it clears out.
Your description sounds more like the engine isn't getting fuel. If the plugs are wet when you pull them then there's fuel, but be sure.
Obviously everything was fine until the new ecu was installed. I would double check everything you touched when you did that work because something you (or the new ecu) did then is what caused the problem.
I'd go over to the Haltech forum and ask those guys what you've done wrong.

If you didn't let it idle for too long you possibly flooded it again. Have yo changed the plugs since? If you haven't put the fuel pump relay and everything back. You man not have any fuel in your lines to start it up. Sounds like your car is getting either too much fuel or no fuel. You deffinetly have spark since it did start. I think your mistake was with turning it off a lil bit after you had finally gotten it started therefore flooding it all over again. If your tps it can cause to dump more fuel then needed and flood it.

Hello sir,
I have a microtech LTX-8 in my 7 and once had a symilar problem reguarding flooding. I took it to a place to get emissions done and when they went to move it onto the lift and turn it off they flooded one of the rotors pretty bad. It was terrible because i didn't see them do it but it came out running like poop. Long story short i spent the afternoon getting it sorted out, which i eventually did. Looks like you know all the old tricks as far as getting it unflooded. When you pull a fuse just pull the main fuse for the microtech which should be somwhere near your intake manifold in one of the harnesses running over your engine...also the best anti theft device on the planet...really easy to get to. Make sure you crank the sh** out of it for a good few minutes, giving it a rest every 20-30 seconds...if it is flooded decently you can see the vapors flying out of the holes where your spark plugs were. Sounds like your motor flooded again when you shut it off after putting in the stock ECU and running it. The only time my car has been flooded(once) is when it was only run for like 10 seconds to get it on a lift. So just unflood it again and give it a try. New spark plugs are a plus, but not neccesary provided you clean up the old ones and they weren't too old in the first place. If it woln't start after the deflooding with the microtech then you may have some problems. Who tuned your ECU?
