So are you saying that cylinders 3 and 4 aren't getting any fuel because there is either a problem with the MS, Wiring, or injectors? Or are you saying that the two look like they're being flooded and the others are running fine.

i dont know, how would i tell? All i can see is that there is fuel on injectors 1 and 2 and none on 3 and 4. If i pull the plugs and let it air out for a little bit, then it will idle decently for 5 seconds or so.

Did you get your injectors flow tested? If not couldnt it be possible for cylinder 3 adn 4 to be clogged?

yeah, they were supposed to be cleaned and flow tested, but i bought them on ebay so, who knows? I could try to switch them around and see if the back ones smell like fuel after that.

on, when i said there was fuel on injectors 1 and 2 i mean spark plugs. there is fuel on spark plugs 1 and 2. I dont know though, if i let it sit for a while, it will idle for a few seconds, that seems to say that its flooded. I just cant figure out how to get less fuel, i have tried pulling the fuel WAY back in everything and stepping it up to no avail. I think my cranking pws are good because it will catch and try to idle then die. its almost got to be either the after start or the idle cells in the ve table. im pretty much at a loss though.

Dude, simple question. WHOS MAP ARE YOU USING?

If you are using DIYAutotunes, you have to use 13.1 in the reqfuel calculation. If you dont it will only make it more complicated to get it going.

I am using, diyautotune's and when you said that i should be using 13.1 i switched it to that and it changed my req fuel to 7.5 like you said. The only other thing ive changed is the cranking pw's and i lowered the idle ve cells to around 40 Im still having the problem where it will run for just a second then die. It backfires and it runs better when it has been sitting for a while but still wont stay running for more than 5 seconds.

okay, so im thinking that my 3 and 4 injectors are bad. The plugs that are in there show no signs of combustion and do not smell like fuel. The 1 and 2 plugs however do smell like fuel and are discolored. Is there a test that i can do to back this up or should i just switch them around. I notice that when i am cranking, it does feel like there is some combustion and its not just turning over with no result. Im thinking that maybe the front two are working fine its just the back two wont catch and kill it. However, i dont think that explains why it runs better after i take the plugs out and let it sit. im just throwing ideas out here trying to stir some thoughts up.

Pull the injector clips, test the injector with a 9 volt battery and some small jumpers. The injector will "click" or snap open and the 9 volt won't hurt it. They might just be stuck if they've sat for a long time without being run.

The injectors came with pigtails so i will clip those on there and try it out.

so i figured it out, only one of the injectors works. so anyway, im in the process of returning them to the ebay guy i got them from, he said they were tested and cleaned so, i should be getting new injectors or my money back. thanks to all who gave me suggestions, too bad i couldnt get it running! oh well, im sure i can get it straightened out and get some new ones in.

Put the stockers in, set your overboost, and get back on the road.
