Loaded up a file for the stock injectors and gave it a go to no success. It ran for a couple seconds but only nursing it. And it was running terrible.

You double check your MAP sensor?

HPTuners showed MAP was reading

But was it accurate? I remember you said it just popped right out when you were trying to install the engine. If it isn't all the way in and giving you an accurate reading it could be screwing you up. I don't know that much about engines, but it sort of sounds like an air issue

I replaced the map that was torn out with a new unit. Went in perfect. One of the next steps is just throw some sensors at it lol

Try the MAF 1st!!

Sorry i didnt get a chance to update earlier this morning. Today was a busy day at work. Here is last nights findings.

I installed the stock injectors and loaded up a stock injector file. Got my hopes up for a second bc the bleeding down of fuel pressure went much slower. Tried to fire and got the same results. Ran for about 6 seconds but SUPER rough, and only stayed running while playing with the throttle. soon as i let off the gas it died. :-?

Next i pulled the valve covers to see if anything was up. Nothing looked odd to me other than some stuff gathered by 1 valve spring. Turned out it was some rust/dried up oil that was in the valve cover. Vacuumed up and proceed. Hopefully this didnt hurt nothing.

Cranked over the motor a few times to make sure every valve opened up, and everything looked normal.

Part 2

Pulled the plugs again to check em out, same case as the first time. 1 and 3 look brand damn new.

Got the right firing order in there?

Looks like what mine was doing when I had coil packs messed up.

It’s even possible to mess that up?

If you ever had the coils disconnected from the coil harness, absolutely.

I had the whole thing undone when I was relooming the wires.

Walking down to check now

How does 1 tell if it’s wrong? Is there color coding per coil by firing order?

Yank pcm plugs, find pin out online, trace pcm to each coil. Should be easy

I'd still do a compression check. If they aren't coming out wet/stinking like gas after cranking for a few minutes, you have to figure that out too. You did verify spark though but I agree it could be swapped. Honestly, why not swap the plug wires the best you can so coil 5 goes to cylinder 1 and coil 1 to cylinder 5? Beats tracing out wiring and should answer your question pretty quick. You'll definitely have to help the car idle until it starts getting up to temp, first start problems. It should be obvious though if it is running like **** that you have issues still.

Update?

Yeah, for real, we need more updates. We're all invested in this by now

Sadly weekend was filled with non car stuff.

I pulled the coil harnesses and double checked them. Sheds send me over the wiring info. It fired up but its still running rough. Wiring on the coil harnesses is pretty rough though. There is some funky stuff going on. Only looks like fusible links within the harness.

Itll start by nursing the throttle, and stay running by playing with it. once i got off the throttle it would pop. Hard to see in the vid, easier to see on a phone, but the last few seconds of running, when it is popping it is at straight idle. And i key it off, it doesnt die.

Those are commons that are soldered and then shrinked (heat shrink with glue in it) there is a common ground and power for all the coils in that harness.

You verified each coil plug was going to the correct cylinder's coil?

Yeah thats what it is then. I was like oh boy, this looks like a hack job lol


Me thinks.

I have an extra harness you can have if yours is hacked up. I won't be back from Vacation until Sat night tho. Won't help for #RW2017 but might help you get er going.

I'm really starting to think tune/timing issue.

Just curious, how fresh is the fuel?

It 100% has gotten better since the injector swap to stock units, and going over the coil pack wiring. It doesn't give off any stupid loud backfires, and i haven't had any backfires threw the intake. But clearly something is still up. Hopefully today i can have Nish come over with HP Tuners and let him have have it.

#RW2K17 isnt looking to hot, but im not giving up until its monday afternoon and the rental is over.
