like the topic says its a 93 civic 2dr ex d16z6 i replaced the timing belt due 2 water pump freezeing did leak down test 2 make sure no bent valves got it back together and it wont start so i checked for spark found none checked fuses found all good swaped dizzy out plugs and wires still no spark cheched dizzy for power and ground found ok what else can i check? o yah i was gonna try a diff ecu but this is an automatic and no 1 i know has an auto ecu its a guy from my works g/f car so i need to get it going

 

Heh, check the ECU because there's not much left.

Did you change the entire distributor?

 

Was it a known good dizzy?

Typically it's going to be your igniter or coil. With the age of the car it's good preventive maintenance to replace it with a rebuilt dizzy.

If the dizzy works in another car, it must be the ECU, IDK

 

I CHANGED THE ENTIRE DIZZY i opened the ecu up on both sides and inspected for burt connections but found none

 

ya it was a known good dizzy but it was off a d15 out of an eg hatch just used vice grips to hold it in place since the bolt holes r diff but it still should have made spark

 

So there's power to the dizzy plug, but no spark?

Most likely means the problem is a ground or the dizzy, but you said you changed the entire dizzy, so I don't know.

 

yah good power and ground i even used my power probe to apply power and ground at the same time directly still no spark

 

It's along shot but did you clean the ECU ground on the thermostat housing ?

If you gave power to the distributor from an external (not harness) source, and when you cranked it it still didn't spark, then it's a problem in the dizzy, most likely the igniter if you're not getting any spark at all.

 

i just tapped into the harness and added power and ground and i tryed it on both dizzys no didnt try cleaning the ground i just checked it made sure it was tight

 

ne1 else have ne ideas i will clean the ground on the t stat when i get to work on monday and try to round up a p28 auto ecu

 

BTW if the wires are all hooked up right and powered and the dizzy is good you should be able to get spark spinning the dizzy by hand (not even bolted on) as long as its grounded.

I bought a high perf dizzy once and the guy behind the counter connected some wires and tested it that way (spun it by hand) and there was strong purple fireworks.

 

ttt

 

ideas

 

UPDATE!! im a dumb *** after being stumped i decided to take apart the dizzy only to find a loose wire to the coil on my "known good dizzy" one of my friends must have decided to take it apart at one time and never informed me of this but on a good not the car is now fixed time to go drink some
