Trailing coil yes (3 wires) and what does "no 12 volts" mean?

 

Nevermind about 12v I forgot b/y has 12v

 

X-0v, U-4.24v, M-.74v, 3d- 1.75v, 1g- 12.02v.... In any gear for 1g.

 

If pin 1G is below 1.5 volts in neutral then that pin is okay. There was a poster on the main board this morning who said he had no spark and that his CAS ohmed out properly at the ECU. He ended up cleaning the CAS plug (the one at the CAS pigtail) and this fixed things. Since your injectors click it would make sense that this would not be of help but since your coils still won't fire properly you just might want to give it a go and clean the pigtail connector to see if it makes a difference.

 

I'll do it tomo weather bad here but if that's not it im going msd 10/18 with my school money

 

When you replaced the stock coil w/the MSD unit did you also replace the igniter too?

 

No i just Dissconected the leading and plugged msd on it but either way I didnt get spark and the ignitor was switching

 

Cleaned all connectors just about. No spark spark still but what is the thing that looks like points by the slave cylinder resivour

 

Not familiar with what you are talking about. A pic would help.

 

Nevermind has to do with tac system not ignition. but ya I am still w/o spark

 

Not sure if I clairfied this or not but both cream colored and black wires coming from ignitior switched from red to green on my short finding tool/ smart test light lol

 

Hey u guys know if I can swap my leading ignitor with an aftermarket one and would my msd fire if I hooked up g/y and blk/yell cause when I initial tried msd I unhooked stock coil from ignitor and put msd in its place, but got no spark still

 

Hey are u sure I dont need trailing to work in order for leading to fire i know someome who races a 79 and is an instructor for smog that says he's pretty sure u need both sides to be switching to get spark on leading

 

I'm am sure. There are a number of threads on the main board where the car has been run w/o the trailing working or connected. A 79 has a very different type of ignition system to it.

 

Going to het an igniter checker Thu but our stock coils would have to be replaced with dis coils right ? Cause my msd isn't, maybe that's why it doesn't spark ..... My stock is outta spec and msd is in spec but I'm pretty sure its not dis

 

What are "dis coils."

 

Distributor less ignition coil

 

I'm sure you could find coils in the used parts section for cheap and get an answer to your problem in a rather quick manner.

 

Off subject and I'm getting a coil with igniter Monday or sooner. But theres a 86 t2 for sale over here that needs ecu ans radiator that has 30k on rebuild .... Now the ecu is probably diff then mone correct.... Mines non turbo, reason i ask is when I look up ecu at wor theres no option for. Turbo or non turbo

 

The ECU for the turbo is different than a non turbo so they are not really compatible.

 

Got my coil ohm .06 and I saw it sparking in a 86 with blown a seals so I going to put it in mine in then am and ill let u guys know and how should I clean fuel tank ..... Compressed air I don't wanna drop it.

 

Ight thanks satch I got spark from the coil on that poor over heated rx lol 234k but u think I got loose tach wire ? My trailing ohm good but igniter could be bad like my leading ..... When should trailing fire and I don't have tach Sig just spark on leading and it would run but fuel tank needs to be cleaned some how

 

If the leading coil works then a jumper wire from the Black diagnostic wire to the trailing coil Black diagnostic wire should make the tach work. Since the tach works off the trailing coil this coil would have to work for the tach to normally work.
