I have been stumped but I know there are some here who won't be. I'll try to make this short and to the point.

1990 Integra GS 1.8L
Well maintained since purchased. Timing belt changed at 90K and it currently has 153K miles.

1. Failed emissions test. Hydrocarbons/CO2 too high.
2. Replaced O2 sensor, plugs, rotor, dizzy cap, fuel filter.
3. Drove great for 8 hours then stalled on highway and wouldn't restart.
4. No spark. Discovered coil went bad. Installed new one yet still no start.
5. Haynes & Chilton tests completed and narrowed it to the Igniter/ECM
6. No go on a replacement igniter. Needed after-market heat sink. Not stocked anywhere in Phoenix.
7. Got pissed off then bought rebuilt dizzy with all new components.

Yahoo!!!!!!!! Started right up! Started to adjust timing and car stalled again. *#$% Wouldn't restart.

8. Dizzy cap and rotor seemed cheesy so bought new ones from NAPA and installed.

Oh Yeh!!!!! Started right up again and adjusted timing with no problem.

SON-OF-A-!!!!!!!!!!!! Ran for 45 minutes then it stalled again and AGAIN no startage. No spark either.

Am I the only one in the world that this has happened to or ? Please help if you can, this is my daughter's first car (I've had it for 12 years) and gave it to her recently. She's bummin' and so am I now.

spark plug wires, swapped out ecu for known good one, timing belt properly on, compression results, valve train damage?

curious...............is that no spark to all cylinders?

Thanks for the response. I am not getting spark to any of the plugs. No LED flashes on the ECU/PCM. I am totally bummed out. Other than rebuilding a tranny I have always been able to fix anything. I must be loosing my touch in my old age. I can't believe that no other Teg people are willing to toss in their experiences. I thought this forum was cool for everyone not just the ones who are trickin' out their ride. Thanks again for your response.

I would check all the connections from the Dizzy to the ECU. There could be a problem inside one of the connectors. Try that and see what you have.

whtteg, thanks for the reply. I will certainly do that. Tonight I retested everything that I first tested and I am back to where I first started.

I am thinking that there might be some other component shorting out the dizzy components. Would a purge control sollenoid valve or M.A.P. sensor cause this? It amazes me that I bought a new dizzy cap and rotor twice and each time the car ran for awhile then all spark died. I'll post the follow-up after checking all the connections and as much wire that my fat hands can get to.

Oh........after absorbing the wiring diagram into my boggled mind I have traced the coolant temperature (TW) sensor is tied into the same circuit that the ignitor is on. Maybe?

are you sure your ecu isnt going out on you? try that first around here i can get them all day for $10 at the junkyard. it almost seems like its sending to much spark and fouling the coil but i dont know. as far as the coolant temp sensor i didnt even have mine hooked up for a week and it ran fine. look at the ecu when u first put the key into run position i think it should flash then. if it doesnt then it might be crap

What kind of codes is it giving you?

just to throw this into the mix... Stock Coils for Integras are POS. they are not strong enough to provide proper spark. think about an external coil but i suggest having a pro put it in. it's a little tricky and if you mess up you could blow your distributer (not saying i have done exactly that before) hehe.

oh yea. they over heat. i meant to throw that in there.

actually, honda/acura ignition systems are pretty damn good.

Exactly I don't know where he got that terrible info about them being crappy.:shakehead The stock ignition system in our cars is more than powerful enough to support large amounts of power. If you are going high boost or really big shot of N20 then maybe upgrade.
I ran my stock ignition on the bottle all the time and when I got a Jacobs Ice Pak and went to the track I actually lost about 2 tenths. Stock not powerful enough huh? :shakehead
