turbo E30 wont start, pig rich

[kamotors]

MY turbo build is here http://www.r3vlimited.com/board/show...=225271&page=8

I've just about finished the E30 but after I installed the 30lb fuel injectors I cant get the car to start. I figured it was running too rich and fouled the plugs so I swapped spark plugs and its still wont run. The plugs I pulled out weren't wet even though my exhaust had black spooge in it. The car did start before the injector swap, I'm running the Miller WAR chip with the turbo base tune specifically for these injectors and a 3.5" MAF.

horrible video of car trying to start, makes me sad

That's strange. Are you running wideband?

That's strange. Are you running wideband?

Not yet hooked up, I'm just trying to get it fired up real quick to make sure all is working. Car wont be driven until wide band is hooked up.

Did you check to make sure you are getting fuel/spark? WAR chip come loose slightly?

[kamotors]

its 100% getting fuel, way too much of it, and seeing as it starts if I keep it floored, it probably has spark. video shows how rich it is.^

Ah, sorry. Didn't watch all the way until the end.

Were the injectors used? Maybe they are leaky? Where did you get the tune you are running?

they were rebuilt and flow matched injectors. I got the tune from the forum, I looked at the tune on the computer and all looked fine. Car started with this tune,19lb injectors, and a 2.75" maf, (which its not meant for). Now that I have the correct MAF and injectors the car doesnt run:(

I'm pretty sure your ecu goes in to default mode when it does not receive a O2 signal

well, that would explain everything.

Im going megasquirt so Im not even running factory o2 lol

Sounds like airleak on intake side to me.

[kamotors]

discovered my injectors were low impedance, which is likely causing the whole issue. ordering new injectors today. The WAR chip has the option to turn off o2 sensor also.

You know, I was going to ask that. lol

Glad you figured it out. I had a similar problem but turned out the be fuel soaked plugs.

30lb is too big anyway! Get some 24lb in there.
