Code 14? / Code 24?
 

Is this a tech or mod question? Both, so I put it here w/ what info should be pertinent.

Among other things I installed a 2V7F w/ a reman Z32 MAF and sr25det injectors.

I inspected the injectors, all looked good with a ohms reading of 12 +/- 0.04.
I sent them out to get new o-rings, pintel caps, screens, ultrasonic cleaned, spray pattern tested and checked for flow rates. I did this as a precautionary measure to avoid any issues. :rolleyes:

I am getting a code 14, injector #1

I am also dumping a crazy amount of fuel into both sides of the motor. I have true duals so I can know both banks are getting too much fuel. My little garage is 100% filled w/ fuel smoke in about 30 sec. of idle. It burns the eyes and lungs and takes some time to clear out. I have not checked fuel pressure or vac signal to fpr, but doubt that either could be causing so much of a rich condition.

I will be swapping injectors to see if the code moves around, but was wondering what others thought about it so far. I have double checked vac lines and connections, injector resistance and MAF wiring. I guess I still need to check the injector wiring, hope I still have that injector tester thing in the tool box.:)

Other mods semi related to this: intake gaskets (bolts were loose but I already bought the gaskets, so why not), both knock sensors (both were cracked), plenum and T.B. spacers (OT talked me into it), all rubber lines under the intake and the IRIS check valve (old hoses and cracked valve)... I think that's it.

Any takers?

ah, you are running a z32 MAF and not a stock MAF, right?

Made the edit.
Yes Z32, had to buy 2 plugs for it because the 1st one ran away for a couple of weeks. It showed back up after I bought the 2nd one.:rolleyes:
Stupid elves.

Can someone add a ? to the end of the title for me? I don't want it to look like I am blaming the ecutune for the issue.

It should read: code 14? due to ecutune 2V7F?

Thanks,
Shaun

"I will be swapping injectors to see if the code moves around"

Excellent first off check which should disclose something. You advise that you sent the injectors to experts for attention. Could one be very much out of shape. :confused::( In which case the bill is also out of shape.:D

I could only test resistance of the injector coil on the before and after. I found no change in readings and I have tried 2 dmm's. I get from 11.8 to 12.1 ohms which is well within spec for these injectors. It is really frustrating to not have real time data when dealing w/ this issue. I have no idea what the ECU is sending out for a duty cycle, and can't monitor voltages as my test equipment is low grade. I need more data to form opinions here. Anyone got a 'magic' wrench handy?:lol:

I had noted that you had checked the resistance and compared this with the OEM in case there was a difference. Injectors are very much dependent on mechanical skills when it comes to overhaul and adjustment. Blues are not difficult to suspect in this area.;)

P.S. Please clear your PM in box.

PM cleaned, checking stockers now...

Thanks btw

Have you dropped LAN a PM/email to get his thoughts on what's going on?
-Bill

Will do, and thanks for the input.

Hey, no problem!

Question - what was the flow rate for the injectors when you had them checked out?

-Bill

As I am lazy at working on the car. I got that info several months ago and will have to look it up to give you an answer. I remember that I thought ,at the time, it was within stock spec, for those injectors. I think it was around 372-373cc's.
Having a damaged brain I can only remember things for a short while, but I am sure to have made note of any discrepancy if there was anything worth noting.

Looking for the papers...too many folders of info...where did I file it...

38.1 lbs/hr flow rate is what I got on average, good flow, good pattern before and after. I didn't need the service done, and as the seller stated they only had like 30K on them at the time. I thought better safe than sorry.

I don't have a scanner to give all the details of the print out, but I think it all looks good. I will swap injectors tomorrow and see what happens.

Tonight I swapped around injectors 1,3 and 5 (1w/3, and 1w/5).

W/ the 2 blue wires plugged in I started the car for 30 sec to clear the code. Next I removed the wires and restarted and ran it for a minute to get the CEL to reappear. I checked and still got a code 14.
Just in case I didn't clear the code properly I have disconnected the battery to drain the memory. the air is clearing for now, but I will recheck for codes later tonight.

I also checked injector signal on 1 and 3 and they both looked the same, so I am opening the best bottle of beer ever: a Samuel Adams Double Bock!

I am starting to think I know why the car is flooded w/ gas and will post what I think after I try to correct it. I am embarrassed to say what I may have done wrong.:o

As LAN brought up, I have used liberal amounts of vaseline on all the o-rings. He made a good point that a torn inner oring will flood the motor w/ gas while a torn outer oring will flood the engine bay with gas.

p.s. My stock injectors have ohm readings from 11.5 to 12.1 which is within spec., and same as the replacements.

Main thought
 

The question bugging me over the last couple of days: What is the possability that the code 14 means something else?

I mean an exhaust leak can set a O2 code. A bad MAF can set a IAC code. A dirty MAF can set a MAF code and O2 codes. A bad cam sensor may not even set a code...
You see what I am driving at?

When you changed injectors, did you run the fuel rail dry before you started?
If not, then gasoline remaining in the fuel rails can pour into the cylinders and flood/hydralock the engine.
