Thanks George. If you do have a new relay, I would love to buy it off you. I would even be willing to help you search for it!

Going to go jump my relays... WOOT thank you E24 british guys

Messed around with it all night. I got it running!

SO my relays are fine, jumping them made no difference.

I heard only a few cylinders firing, and since my spark was fine I figured it must be my new injector harness... so I pulled it off and did a continuity test on each of the two prongs. I figured out that it wont read continuity until the key is in the run position.

All 6 injector plugs were good. cranking the engine without them plugged in though, I heard 3 or 4 cylinders fire! The engine was flooded! A jump start later and having them plugged back in and the engine ran! I let it run for oh 20 minutes idling while I tried to quickly hook up the throttle cable... I failed at that and the screw extractors I bought I couldn't get to bite in.

Anyways after 15 or 20 minutes the idle dropped down from 1500 or more to 1000 then again to 500... the engine ran smooth enough at 500 and the exhaust sounded like a Harley almost. It was kind of cool

THEN THE ENGINE DIED! I couldn't really get it started again and thus I pushed it to my driveway and gave up for the night. I tried unplugging the injector harness and cranking it to un-flood it again but that didn't work. When I finally gave up the engine is SUPER close to starting. SUPER CLOSE.

So I unplugged the battery again and Ill come back to it tomorrow. I am excited that it got running... but at the same time mad that it wont go again.

Dude you need to TRULY diagnose your shit. I feel bad for your car. I understand your young but I feel like your just making shit worse by trying to fix it yourself. That's just my opinion. Bring it to a shop that knows e30s pay to have it fixed and drive the fucking car!

I know the problem now... the ECU just needs to learn what the fuck is going on

[5Toes]

It started today... I did the same procedure. Crank car with out fuel injector harness hooked up then crank normal.

It started and idled fine. Then I come back 2 minutes later and just as I hop on and put it in drive it dies. FFFFFFFFFFFFUUUUUUUUUUUUUUU

Now it wont start again but is still super close

Put your old injectors back in.

[5Toes]

Ill get around to that tonight... got a bros birthday to get to

[Sagaris]

Don't run 17.5# injectors on an ECU mapped for 14# injectors.... and if you've dicked around with the AFM, then un-dick with it and revert it to stock. This includes M30 AFM and AFM tension adjustments.

[5Toes]

I cleaned the AFM with brake cleaner and a paper towel with my finger. I pushed the flap a few times, but was careful that I didn't get the element dirty.

Maybe thats my problem? - http://forums.bimmerforums.com/forum...d.php?t=569030

i had a similar problem when i had my temp sensors screwed up and in the wrong spots. maybe the lack of coolant is causing it???

[5Toes]

Well a bad temp sensor means that it will send too much fuel and flood the engine.

My stomp test dont work... I know that now! lol unplugging the afm or fuel relay still displays the no errors code.

[Ceeker]

did you make absolutely sure you don't have any vaccuum leaks around the injector seals?
Did you also check to make sure you pump isn't on it's way out. it could run for a bit and then lose pressure. Also check to make sure your pick-up in the tank isn't dirty and sucking up shit to cause the car to stall. if the filter gets clogged it will starve the fuel system. just something to consider.

check your bentley's manual and systematically eliminate the potential trouble that might be present.

[5Toes]

Well today I am...

Testing my coolant temp sensor
Removing Injectors
Putting old ones back in

Then going from there
