[U]PROBLEM SOLVED, SOLUTION: CORRECTED THE FIRING ORDER. THANX TO USERNAME "WRIGHT" /U]


Hey names Patricio and I was wondering if you can give me some tips on why my car is misfiring on cylinders 3-4 base on the stuff I’ve checked so far:

-checked the resistor box plus the connections and even swapped with another one and no go!
-checked the injectors at InlinePro they told me they were good with a full flow.
-checked for continuity on the injector plugs to the resistor box and they were all good
-check the continuity from the injector plugs all the way to the plug that goes to the ECU and it was all good.
-brand new MSD distributor cap and rotor
-The MSD Digital 7 Plus is set on selection 4 for 4 cylinders.
-there's spark on all cylinders
-compression test came out to 150 all across on all cylinders
-Fuel pressure regulator reads 40-46 psi
-the computer I’m using is an s300 and the only code it shows is the idle control
-changed spark plugs with the right gap
-checked the timing of the motor and to me it all seems good (checked the cam gears, crank and the flywheel they all line up.)


That’s all I can remember for now but here's something’s that I might need to re-check(please correct me if I’m wrong) and if there's something else let me know please:

-need to re-do the valve adjustment maybe on just cylinders 3-4 since that’s where they are not firing.
-check the motor timing again
-get new spark plugs

My set-up:
1992 Civic EG6 hatch
Hondata s300
MSD Digital 7 Plus with Coil Blaster
H22a fully built bottom block
H22a stock head
Inlinepro Intake Manifold
Inlinepro 3 Bar map sensor
BDL Throttle Body
Precision 1000cc Injectors
AEM Fuel Rail
Stock Fuel Filter for now
255 Fuel pump
Aeromotive Fuel pressure regulator with pressure Gauge
Custom Turbo manifold
T-70 turbo .70 Ar Compressor and .84 Exhaust
Tail 46mm External Wastegate
Tail 50mm BOV
InlinePro Biggest intercooler for EG Hatch
2-3 inch Intercooler pipes
Moroso Catch can, oil pan.

****Any tips are welcome and sorry for the grammar ect... but please keep negative comments away.

u should just get a new motor....lol sup fagg

After the episode that one guy just went through; make sure you are running the correct firing order from the distributor to the plugs.

colocho19

sup culero give me a k-series then, lol.

colocho19

who went through all of that? give me the link maybe I can learn something from it, but the firing order is correct I got it from another h22a working motor, thanx tho.

wright

I am that one guy. lol

Double check the firing order. It sounds to be the same issue that I had except that it was two and three cylinder was not firing. Seems like you also checked the same things that I did like the injectors, wiring, ect.

Are the problem cylinders wet with fuel at all?

colocho19

Lol, well thanx for looking into my problem. Ok do you happen to know what the correct firing order would be for my h22a because the way I have it's cylinder #1 is to the bottom right of the dizzy and cylinder #2 is the the bottom left of the dizzy and cylinder #3 is to the top right and cylinder #4 is to the top left.

Yes, when I turn on the car and turn it off then take the spark plugs out from the cylinders 3-4 they are wet with fuel. Any more suggestions??? thanx.

wright

^^^ Should be right a quick google search.

With the plugs being wet in the problem cylinders you should be good on the fuel part. Now I know that you said that you are getting fire, but are you at the cylinders that are having the issue?

Let me add some more stuff that I did:

-I swapped Injectors from cylinders #1-#2 to #3-#4 and the problem seems to stay at cylinders #3-#4
-Then I swapped the Injector PLUG from #1-#2 to #3-#4 and still the problem seems to stay at cylinders #3-#4

Is your firing order the same as in the above picture? It sounds like you are doing all of the BS stuff that I did other than checking the firing order.

If all checks out it might be a valve adjustment issue, but I think that it is something else. Most of the time the big problems like this are actually little ones that we look over because we over think the issue.
