Just yesterday, my car started to sound like a Subaru WRX. I have a stock B20 with GSR trans in my 96 Integra. I checked spark and compression, all is good. Swapped out spark plugs, wires, and also fuel injectors. There is voltage to all injectors (tested with meter). One thing I noticed is that #1 cylinder spark plug still looks new when i removed it after driving around the neighborhood. I guess that this is the culprit, but I can't figure out why it's doing that. Could this be due to a bad fuel rail maybe? I have also swapped out the dizzy and checked all sensors and even swapped those out.

 

yeah, not getting spark or fuel in one cylinder. try moving the injectors around (swapping cylinders). if that doesn't work, try the same thing with the spark plugs. should be able to narrow it down to one or the other. and hope its that, and not something more serious.

 

i have 3 sets of obd2 injectors for $25 shipped per set if you need injectors

ohm test all spark plug wires, make sure you don't have a dead wire.

injectors, wires and even a plug are possible. if you drop a plug on concrete there's a good chance it will never fire again

 

I had the same noise from my gsr. Turned out to be a bent valve.

 

Had this issue recently. Faulty ecu with no CEL or anything. Car started right up everytime.

 

I'll Try those. I already tried a different ECU and still the same.

 

op said he checked compression

 

My ls did that once. Turns out that 2 lifters were just laying in the bottom of the head.

 

Thats great, I read that. Just merely stated what my problem was.

 

when did this thread become about you?

 

These guys did the same but your not gonna hate on them? Stfu. Have you ever thought someone else who searches could find this thread and learn from everyone who had this this noise?

If we had a thread that stated a problem with lots of possible fixes or people who say what was the problem for them it helps someone searching for this problem not to start a new thread.

Since your so good at following the forum rules why dont you "sell" your injectors in the marketplace or give him a link to your for sale thread. Listen to yourself before attempting to be "a mall cop." Hypocrite.

 

Op said he already swapped those
So you offered injectors knowing he stated he had swapped those out. Also he stated he swapped the spark plug wires, but you still told him to do that. Stfu and gtfo.

 

I tried a diff. ecu and swapped injectors around and still same problem. Not sure what's going on now.

 

sounds like your getting no spark in one or two cylinders and thats why it sounds like a wrx,
did you tripple check the firing order on the dizzy?
any chance your injector wire harnes is pinched in any area? look at it close and see if any wires may be damaged.

 

Yes, I triple checked the firing order and there is voltage to the injector wires.

 

I replaced the fuel rail and injectors again, and still same issue. I metered all the wires for voltage and there is voltage to the injectors. Any other ideas anyone want to add?

 

if you already ohm tested the spark plug wires and they all read similar for resistance, the only thing left is replacing the plugs and trying a different distributor

 

If nothing else comes up, check your valves. Check valve lash.

 

I found the culprit. There was bad continuity on the injector #1 red wire. I traced it back to the Ecu. And found that the pin on one of the connectors was pushed in and not making contact. I pushed the pin back in and that was it. Thanks for all the feedback.

 

how in the world did that happen? you have hacked up wiring'?

 

Note sure. But, feel better now. I have had this happen on a copy machine at work.
