Hey guys I'm new to this site but I can't find help anywhere else so I was referred to look here for help. I have a 1997 EK hatch with an ls in it, I just did the swap in my driveway. It's my first swap but I'm pretty sure I did it right. But only two cylinders are firing. 1 and 3 are not iring at all but 2 and 4 are strong and running like normal. I did a comp test and I got 140 all the way across. I checked spark and it's getting spark, I checked if the injectors are shooting fuel and they are, I don't know what to do next. Someone please help! Thanks for all replies

 

do you have the 1 and 3 wires backwards?

 

1,3,4,2, starting from bottom left going clockwise

 

How did you determine that they aren't firing? Check the valve timing and test the distributor sensors or try a different dizzy. How did you check the injectors?

 

I checked the injectors by holding a bucket and getting my friend to crank over the engine and see if they all shot fuel, I know it's firing two cylinders because when I pull the plugs to 1 and 3 there is no idle fluxuation or bogging, also I can hear it. I don't have a timing light or else I would check timing. Distributor is working correctly cuz I'm getting a strong spark out of all cylinders

 

Valve timing = The relationship between crank and cam position as held in place by the timing belt.

 

The distributor has three sensors inside that govern fuel injection timing, among other things, by telling the ECU what positions the cams, crank and pistons are in. If they aren't working correctly, the fuel can spray at the wrong time and/or the computer's timing adjustments can be off.

 

Well the distributor is hardwired but I'm pretty sure each wire is p the appropriate wire. I got a diagram of the colors and matched them, so the could be the problem. It's obd1 distributor on obd 2 harness. Do you know what colors go with what so I can double check it? I will also check timing

 

I've got diagrams here for the distributor sensor connector but they vary with different motors. For 96-00 integra motors, you should have a connector like this:

1 2 3 4
X 6 7 8
9 X 10

X's are unused terminals. The three sensors inside the distributor are the TDC sensor (Top Dead Center), the CKP sensor (Crankshaft Position) and the CYP sensor (Cylinder Position). You separate the connector and measure the resistance across each sensor's two pins on the dizzy side of the connector.

TDC: 3 & 7
CYP: 4 & 8
CKP: 2 & 6

For a 96-99 integra motor, each sensor should show 500-1000 ohms depending on what position the motor is in and the resistance should change within that range as the motor turns. No terminal should show continuity with the ground. If your motor is not 96-99, let me know and I'll get you the correct specs. While I don't know the wire colors, just make sure that each sensor connects to the correct ECU pins. Good luck.

 

It is 95 integra motor (obd1) therefor I have to hardwired the distributor. I just have to match the colors, I rewired it and got it running on all four, but whenever I hit the gas i hear popping and it's missfiring every once in a while, an ideas?

 

Oh, the dizzy was wired in before the connector, removing it. I'll check the colors for you the next time I go out. How did you check the spark? You want to be sure that you are getting strong sparks. Just knowing that it is sparking doesn't mean they are strong.

 

I checked it by undoing it and keeping it plugged in and holding it to a valve cover bolt, there is a good strong spark

 

the only problem i have with it now is everytime i give it gas it struggles, but its opening the throttle. i can give it gas slowly and it will rev up but when i punch it, it bogs and struggles

 

You should find a replacement distributor, try it out and return it if it doesn't fix the problem. According to the info you've posted, you have spark, air, fuel and compression. The only remaining possibilities are timing, wiring and the ECU. If you checked the valve timing then the distributor is the next most likely cause of a timing issue.

 

Someone told me that if it's not reving past 3 grand then it's prob a TPS, is that a possibility? Or vacume leak?

 

There would be alot of missing involved. It wouldn't be like the motor revs fine and just won't go higher than 3k. It also wouldn't cause problems with only two cylinders, at least by itself. Go ahead and test the signal voltages of the TPS and MAP sensors. The TPS signal voltage is checked with engine off and key at on. The MAP sensor signal voltage is checked when the motor has fully reached normal operating temperature and is idling.

 

Ok I'll let you know

 

Could it be the wong injectors? O have d series injectors but someone told me they would work

 

not the problem. wired b series injectors but still no revs

it sounds like im hitting a two step at 2500 lol, its weird :S

 

its going to a mechanic tomorrow, ether no one knows the real working order for the colours on the distributor or im half retarded lol.
