D16z6 to much fuel help!
Ok gues heres a little history of the car. Its a 88 CRX with a d16z6 that is now obd1. It has a turbo kit including dsm 450 injectors, xenocron 255 fuel pump, hondata s300, speedfactory 4 bar map sensor, vitara 75mm 8.5:1 pistons, eagle h beams, ect ect ect.
So my problem is that i had it running very good at idel. I was trying to play with the afr's in hondata and had it sitting at 13.5 while ideling. Then my laptop died. The car still was runing good. I decided to park it for the day. When i came back out to play with it again 2 days later now it wont start.
The car is dumping so much fuell it wont start. Raw gas is comming outa the tail pipe and i have fouled out 3 sets of plugs. So I think its the tune and put a stock p28 tune back on with the exception of mmy injector size and my 4 bar map. Nothing changed. If i do get it to start its with my foot to the floor and it only trys to rev to about 1000rpm. My fuel pressure is at 43psi. I have changed plugs,cap and rotor,wires,coil tested good. Also have replaced the fuel rail,and injectors. Nothing seems to help.
Please please please guys i have been building this car on and off for 4 years and all i wanna do is drive it. Someone please help. Thanks.

Re: D16z6 to much fuel help!
The problem sounds to be that it is now flooded. Remove the plugs, disconnect the distributor, and crank the engine a few times, let it sit for 10 minutes, crank a few times, let it sit for 10 minutes again. Then install new plugs, upload your map, and start. Good luck

Re: D16z6 to much fuel help!
Have you tried starting it with your charge pipe disconnected?
I'm just reading into it for how you can get it to run (sort of) with your foot the floor.
That would allow the most air in as possible making it sound like you don't have enough air for the fuel you are putting into the mix.
May even be that you have an injector stuck open and dumping fuel.
You have probably washed out the cylinder walls will all the fuel you have dumped.
Might want to consider putting a little oil in the cylinders before you mess with more just as a safeguard to your rings.
Other than that, it sounds like your injector size isn't right or you have a weak spark.
