engine running bad

[SpitFire]

i've post my problem in the beginner section but none of them help me so i'll post my problem here.

i just finish installing my head because i blow the head gasket.car is accord/h22.

now the engine is running really bad and it's not getting gaz to the 3rd and 4th cilinder.(i say this because the runners of the exaust wont go hot like the 2 others).

could it be not anough fuel pressure and the gaz wont go all the way trough the fuel rail for the 3,4 cilinder?i will do a fuel pressure test later this week.

or , its the injector that are fried? i disconect the injector and I plug it to a 12v batterie for a fraction of second and made them click(all 4 have click and they were all clean).is it possible that the injector click without injecting fuel?some people that i know plug their injector for a fraction of second to chek if they click with a batteri...they never fried one.they suposed to have milivolt to them i know....

how you can chek if the injector have a pulse from the computer without the special test light tool?i will chek this week for resistence of the injectors (supposed to be 1.5 to 2.5 ohm).
i will rechek my firing order but i have chek it the last time.is the firing order different from a h23 distributor to a h22 distributor?i have a h23 dist. and a h22 engine.maybe it's the problem.

i have compression to all 4 cilinders and spark to all cilinders...its sound like its running on 2 cilinder and wont go up in rpm's.


sorry for the bad english, i'm trying my best to improve it.

are you sure you installed the h/g correctly. Seems to me like since your problem started after you changed the h/g, it might have something to do with that Do you see any leaks anywhere from the fuel rail? Or anywhere else?

I made a mistake today that I think might help you. I was running a compression test and I had a spark plug out of a cylinder and I forgot to pull the fuel pump fuse. A big burst of fuel mist shot out of the cylinder while cranking. So, pull out the spark plugs on those cylinders, and make sure to disable your distributor, then crank it over and see if fuel shoots out of the cylinder head. Also are you sure that the cams and crank are lined up properly?

the timing is good and the gasket is in the good position with the UP mark on the top.at first the engine was running good but the fire was not good causing it to stop...now i've fix the fire and now thats the problem.there is no leaks anywere.

are you plugs in the proper place, do you have a dirty fuel filter idk man i am interested to see what else i could be so bump....help this guy out

[SpitFire]

i'll chek my fuel filter.

Hi guys , i have some news.

I've check my pulse with the special testlight tool , i have a pulse at all 4 conectors.
I've also check my resistance of my injectors.all 4 have 11.6 ohms of resistance.
In the manual shop they said it should be 1,5ohms to 2,5ohms.can anyone can confirm this,
my friend has my manual...

I will barrow a fuel pressure gauge to chek if i have anough pressure.
I think at idle it should have 15 or 30 and at WOT it should be like 50.

I didnt chek my fuel filter cauz its rusted like hell and i cant remove the bolts lines.i think i will stop at honda and buy one tomorow.

i've changed my fuel filter...this not solve the problem.

I've also check my resistance of my injectors.all 4 have 11.2 ohms of resistance.(i've substract the resistance of my multimeter)
In the manual shop they said it should be 1,5ohms to 2,5ohms.can anyone can confirm this?

My JDM H22 injectors that I had, were all between 1.5-2.5 ohms, which IS the Honda spec for low-impedence/peak & hold injectors.

I have a feeling you have the wrong type of injectors for the motor from a peak & hold vs saturated standpoint and/or the fuel resistor box being installed or lack thereof may be the issue, depending on what your setup should be.

QUESTIONS:

1) We need to know what year your H22 motor is and if it is USDM or JDM?

2) What ECU are you using, be specific?

3) What year Accord do you have? And where do you live in the world, since it seems you may be from out of the U.S. (this pertains to the type of Accord you have)?

hi , i live in quebec/canada.i baught my accord with the h22 instaled in it.the accord is 1991 ex cb7 and the h22 is between 92-96 from the honda prelude that we have in canada.

i will check for the code of my ecu tomorrow.i dont know if i still have the accord 5 speed w/harness and chiped OR the prelude ecu and chiped.my cutoff is at 8000rpm...

before i replace the head gasket, the engine was running good.why is it running like s**t now.i didnt change the injectors. can the fuel resistor box can be fried?

also, when i turn the key to ON i listen to the pump.its always the same amount of time that the pump is working.is this ok?

you should not be running a resistor box with those injectors. Doing that can seriously mess things up. I understand that you have spark and you believe that everything is in time. Check the timing again. Make sure that all grounds are there and tight. Get a noid light (plugs into the injector connetion) and make sure that they are pulsing. If pulse is present at all then the injectors have a problem. If only a couple are pulsing check the others wiring, making sure nothing is pinched.

I doubt you haven't checked this out yet, but are you sure the plug wires are in the correct order? you say two cylinders aren't getting the exhaust primary's hot, try switching those two.

1) Can someone confirm what type of injector (peak & hold or saturated) should be in a Canadian 92-96 Prelude VTEC H22 motor?

2) Spitfire, what exact ECU are you running?

I can tell you the 91 EX is the 91 LX over here, regardless the vehicle itself will have a resistor box and so the vehicle setup is asking for peak & hold injectors and the drivers in the original ECU are setup for it.

judonoh : i think i dont have a resistor box,i've just asked the question to be sure.i will rechek the timing but i've cheked many times and its ok.i did the test with the noid light , every conection have a pulse.

dbsharp : i've already switch the 2 wire , the engine does not like it...lol

HondaFan81 : i will chek for the ECU in the afternoon cauz i have a brake exam at school.if my car has a resistor box what should i look at if a have one?

mayby the valves ajustement is not right.a guy redone my head and ajust the valves with the head out of the car, by putting the camshaft on the top with the bolt.can he messed up?

thanks guys.

Please answer all my questions.

About the valve adjustment, it could be done with head out of vehicle, but still they have to do it right. You have not answered whether he did it right or not.
