Does the CEL come on? When you try to start the motor and it doesnt spark and u turn the key back what lights come on? Does the oil light come on?

 

get a code reader.

 

are you sure its the spark??? and not fuel related? Ie. do you hear your fuel priming or are you certain that their is completely no spark.

 

I would like to know how you're checking spark...

 

there is no check engine light... and everything is normal all the lights come on that are supposed to.. i pull a plug and put it back in the wire and set it on the block or somwhere where it would be ground.. and check for it to spark or i put a screw driver in the coil wire and put that to the block and check for spark between that or same with plug.. and yea i hear the fuel pump comin on and i checked the fuel line its pushin threw just fine =/ anymore ideas?

 

Check your timing belt, fuses and ground.

 

Remove the distributor cap and check your rotor. This happened constantly with my CRX with it coming lose and turning. It may be that the wiper is broken, corroded or bad too so make sure its in good condition.

 

try accessing another rotor to make sure yours is working, and let us know where you are getting spark from if any at all and where you are not.

 

well.. its a new dizzy with new cap rotor i tried 3 diff caps and rotors.. checked my grounds.. and fuses replaced them all including main relay and the timing belt is still on, and im not getting spark from the cap wires or the coil i dunno what else to do =/

 

With the Dist Cap off, have someone crank the car to see if your rotor turns. If so you can assume the Dist gear is OK, as well as the timing belt. If those tests pass, ensure you have the wires on correctly, then test the coil. I cannot recall if 1994's have an ignitor or not. I'll have to remember to check my manual. They were a problem in the 1993 models.

 

yeah, i tested the coil before it was fine i switched it out 3 times also.. and i checked if the rotor was turning before and it was fine.. i also checked the wiring over and over i took off the ground wires cleaned it to make better metal to metal contact am i fukc'd for good? =/ haha

 

Check the ignitor inside the dist. assy. Its the little block with 3 wires attached to it. Make sure its at the right ohm. Those are known to go bad.

 

i already tried that i replaced all the electrical parts on the inside of the dizzy still dton start, i work at autozone and i can test them all and they all test perfect

 

check every ground that has anything to do with providing spark to the engine. A buddy of mine's prelude wouldn't start simply because the ground to his alternator was so corroded.

 

i checked all the grounds though, and i checked with a light tester there was power goin to the msd box and out of it and to the coil.. but why would it not spark after changed to 3 differant coils?

You sure you have all the grounds connected? There are a few of them...Let's see if I can remember them all of the top of my head...
There's the one going to the main fuse panel, the one on the tranny, the one by the thermostat and the one on the driver side of the valve cover...


Sounds to me like either a wiring problem or a fuel problem...
if it's not something simple like a ground not hooked up...

I would go back and check your wiring... You could have not properly hooked something back up after removing the MSD...that seems like the best place to start looking...

What harness are you using? I know on my F20A I used the JDM harness and I had to rewire a few of the connectors because they were mismatched...

 

i think im using the h23 wire harness and yea i had to change a few of the connectors also but im possitive i have all the wiring good.. its been sittin in my garage for 2 months i been in there day after day.. what is that thing in the dizzy not the ignition module the other L shaped piece.. well in mine i didnt use that i had another external one bolted to the 2nd cam ( bolted just like the dizzy is to the 1st cam) but its just a box with that L shaped thing inside it, it says TEC on the side bran name i guess.. but jw what that was does your f20a have that?

 

and aslo.. when it died i was just driving taking off from a light.. hear a little ping or poping sound dont remember it too well.. goin into second i release the clutch pushin the gas and it gave me a little sputter.. then died when i rolled to a stop i poped the hood and looked for broken hoses or oil leaks thought i blew the motor but only thing i saw was the ignition wire from the coil to the dizzy cap was off the cap completly.. no signs of melting or burning of any sort.. so i thought it just poped off over a bump or somthing.. so i put it back on and still nothing

 

might be silly but did you get the right dizzy for your vehicle? maybe your using external coil dizzy and or not wiring it correctly?

 

mm.. i used the udsm h23 dizzy same EXACT dizzy everything matches up wires, bolts everything

 

Just thought I'd mention that you cant post pics directly from your harddrive. You have to upload them to a photosite and them link them here.

 

thanks man

 

anyone else have any idea?
