So I'm working on a 96 accord w/ f22b1 with a automatic transmission and it has no spark at all. Replaced dizzy and all internal, and the tdc sensor harness at the crank. Fuel pump primes, I pulled the cap and hooked a spark plug wire to the coil and it throws spark but a light Orange ish color one. But once I put the new cap or old cap no spark through it. So off to the auto parts store for a new rotor. Other than that I'm at a loss. Car was just driving down the road and died. I don't know if I'm over looking something, but I'm thinking new ecu maybe.

Its telling you that the crank pulley bolt and key belong on the SLUT. :noel:

I will pull your parts off b4 I set it on fire :yes:
-
Shitty ground?
-
Im done for the night, but I checked the one off of the valve cover, I dont know it there is one on the thermo housing. I couldnt see one but I didnt look super hard eather. So where is the ground for the ecu on the accord? Is it on the thermo housing?
-
ohm out the thin blue wire on the coil back to the shocktower plug same thing my friends b20 had turns out the wire was corroded and not giving the coil a good ground therefore shitty spark but enough to produce the orange spark u say
-
Well I just checked and cleaned the grounds on the end of the intake, (thats where the ecu ground goes) Front batt ground on the rad/headlight support, and the one on the valve cover/motor mount one too. Still no go. And there is no blue wire that goes from the coil.
-
ECU ground is on the thermo.
-
On the f22b1 it was on the driverside end of the intake. I looked and felt all around the thermo and there was nothing.

Is this a chinesse autoparts dist. that your using?

Yes/no
First dizzy was a oem, then a napa auto parts one. It has all oem internals, just a china coil. But with the old coil it had no spark also.
-
i say since its obd2 does it throw a code? if not clear the ecu and crank it till it does?? then jump it or scan it to see what the ecu found
-
No cel at all. No mater how much you crank it no cel. Had batt diconected for 3 months, Would that clear in locked in codes?....lol
-
dumb question but did ya check all the fuses?

Yep.

ok so something is causing the weak spark its not a no spark condition its a weakend spark let me dig through accord wiring diagrams tonight to track down and see where all the dizzy wires go to eventually and i will post my findings and suggestions tomm morning. you said when you hooked up a plug wire to the coil directly it would give you a dull orange spark when you would tap it to ground correct?
-

Yep
-
coil getting bat voltage?

coil getting bat voltage?
Was just going to ask that. mitchell is being a bitch and locking up.
I suggest pinning out the dizzy wires and see if something is "strange" such as high resistance for one of the coil wires. if its not throwing a code its not an internal dizzy fault but rather a coil power situation. I would also check the little spring on the coil sometimes they dont make good contact. there is a little spring in there right?
-
Wiring to dizzy fucked?

did you not read my post??? or any of them for that matter

haha of course I did. I guarantee that is what the problem is. Start tracing wires
-
Coil is getting 12+ish volts.
-
ok and there is a little spring in it right? there should be a thin blue wite coming off the coil maybe its a different color on an accord but its what fires the coil and it the wire in fucked up or has a lot of resistance it wont get a good spark. also give the dizzy and mating surface on the head a good cleaning as the coil grounds itsself to the head
-
R u talking about the little spring inside the dizzy cap? Im gona go and check the resitans on the 2 wires that run from the coil to the harnes on the dizzy.
-
ok, so here it is. The little blue wire you were talking about? On the pass fender? Is that the tach test port? It has 12 volts if thats what you were asking.
-
Somthing kinda weird, When I kick the key to the run position it the pump primes, the cel turns on, The car showes its in park, and D4, when the cell goes out so does the drive light, and then it just shows that its in park. It my brother-in-laws girlfriends car. So I have no idea if this is normal or not.
-
hmm dont think thats normal. never owned a auto honda.

Me either.
-
see i am just trying to think if you crank the car via jumping the starter with a wire will it put a spark directly out of a cap terminal like stick a wire in it like speaker wire and set it near a ground see if a 0 ohm wire will spark to groungd at reg intervals then its cap coil rotor or combination
-
the shift selector thing is normal AJ
-
well I have a crazy idea. Im gona un hook the wire that goes from the coil to the ignighter and hook a wire from the coil (where the wire was tht ran to the ignighter)and kick the key on, and take tap it to the valve cover. It will eather thrwa big fucking blue spark, or a yellow/orange spark. That will tell me if its the power feeding the coil thats weak, or after the coil its weak.
-
Well I unhooked the wire that goes from the coil to the igniter, left it attached to the coil and kicked the key on, then I taped the wire to ground and I get a nice blue spark. So the coil is getting good power, and so is the igniter. I also checked the blue (tac signal)wire that goes from the igniter to the ecu and its getting 12v with the key on. Now I dont know if this matters or not, but I put a test light on the same blue wire and it wont lite up a test light. So im wondering it its reading 12v but it wont carry the amps?
Man im so done with this car. ??? :-\

Seen this shit happen so many times.
Change that junk china coil.
Report back to me when it runs. I know I'm 100% sure on this one, assuming you have fuel pressure, ignition pulse, and good compression.
-
I have a couple extras should you need on AJ.
-
Ok, I will let u guys know tomorrow. Thanks Brian.

what makes you so sure?
What ignitor wire did you take off? that short little one to the coil? do you have any other ignitors you could possibly try? I am thinking it might be defective.
-
you can check the Ohmz of the coil to see if its good...

Already did that and it tested good. I have a sneaky suspicion its the igniter. Gona yard mine out of my car and see if that works. I work late tonight and early tomorrow, so I think its gona be tomorrow afternoon b4 I mess with it again. With that said, when I unhooked the wire going from the igniter, with it still attached to the coil with the key on I grounded it and hit thee some nice blue spark, so I'm assuming that its after the coil, like the igniter side of things.
-
Autozone can test obd1 ignitors... I dunno about yours but its worth a shot...

If you turn the motor over and watch for spark and it is very very faint, about 1/4 of an inch, but there to the slightest bit, then the ignitor is good. Ignitors put out a very small amount of spark when the coil takes a shit.
I'm telling you, change that shit coil, you'll thank me later.

Im gona try the coil first, Then if that dont fix shit, I will try the igniter. If that dont fix it I will then try setting it on fire and collecting the insurance money and see if that works. :yes:
-
If you see the littlest amount of spark, then the ignitor is good. You should be able to get a coil fairly cheap.

Well no chance to work on it today. My father-in-law got tboned in his crx. And broke his ankle, couple of ribs, and got a concussion. Been out at there place setting up arangments to go pick it up tomorrow. Hes gona be ok, but the crx is :'(.......
I will have pis up in a few days of the crx. We are gona go to the yard that has the crx and bring it back to there place. Once the insurance comes out and takes a look and says its totaled, Im gona rip all the parts off it. Its to bat because we were getting ready to turbo it this winter.
-
Sorry to hear that man. I am glad he is ok. What model was the crx?
-

89 hf with all the the stuff from his 89 si put on it. The 89 hf was 100% straight as fuck. The si body was a little beat up. So we swaped everything over. Brakes, stearing rack, motor/trans, cluster, suspention....yada yada yada......
Bet he wish he had a roll cage after he got hit. The car took a pretty good hit. about 40mph right in the drivers side door. The kid that hit him was driving a 92 teg. I guess his car is totaled out too.

Damn, sorry to hear. That sucks dude.
-
Hes ok, and shit happens. Thats all that matters. Hes just pissed that his glasses got broke and he cant see shit now untill he gets a new pair.....lol
Fuck man, life goes on...

i know how that goes i was going to boost my hatch yet a week prior it got rearended by a f150.
-
Well I fucken give up. Off to the repair shop it goes. Not my car, not my problem. I've got 3 other cars wating to come into my garage and I can't suck it up with this dead rock. But this is the first car I have ever drip me.... hope its the last but I doubt it.
-
Did you even try another coil?
-
Did you even try another coil?
Yep tried 2 good working coils, tried good working igniter, tried 2 good distributers. Tried a different ecu. Fuck man Im totaly stumped. So off it goes. :-\
-
There is a crank sensor down by the crank pulley that goes bad too as well.

Replaced that last Saturday with a oem one from Honda them selfs... Brand new
-
Main ignition/fuel relay?
-
if the fuel pump primes and cel goes off consider the main relay working just fine besides where do you get off thinking your the master of diagnosis? if you dont have any idea and certainly dont read what is going on how do you suspect the issues.
-
sounds to me light power to the dizzy or a ground... since you literally tried everything else out.
did you try the parts off the bad car on one that you know is good or only good parts on a junk car... it could be possible that 2 different problems (2 different wires) are coming together to cause it...
-
So I even took a jumper cable and went from the ground on the battery and clamped it to the body of the dizzy to see if it was a bad ground possibly. Fuck I was trying everything I could. And now I didn't try the bad parts on the good cars.
-
Still... that's fucked up...
