no spark - bluetooth 123

[roman.lysiak]

Back at it trying to start the car... 73 tii. I have recently insysalled a new bluetooth 123 distributor, new blue coil, new IE fat wires, new rotor and cap, new plugs  BPE6S. I took out the ballast resistor with the blue coil and have plugged  the green iginition wire directly to the coil + terminal. The red and green wires that went through the relay through the ballast resistor are now dangling. I set the 123 as per instructions including tii curve from the bmw manual... when turning it over I get intermittent putts but no fire. I pulled the plugs and they are covered in fuel, there is no indication that any spark is happening.

 

Any ideas?

 

I want to drive this car this coming spring!!! really bad.

What does your timing light say?  On TDC while cranking is a good start.

 

How's the spark look?  When you pull a plug and ground it, does it make

a nice, fat blue spark in a regular pattern?

Set the TDC for cylinder 1 as per 123 instructions, got the green light to turn on and locked the distributor in place. I need a second had to turn the motor over to see if there is a spark. I can check tomorrow. But the plugs looked wet and smelled like gas. IF there was a spark, wouldn't it just fire. Leaving it overnight to trickle charge the battery again and try again.

just a question..why do some people go for Blue Coils? Nostalgia?

They're pretty?

 

123 failure? or carb failure? - Neither it was the Coil!

gas soaked plugs will not fire.

 

(this is a Tii)

I had thought the 123 preferred a red or black coil, but roberttran pointed out that the 123 site recommends a blue one for the four cylinder engine applications.

what do they know lol. I don't see an explanation for using a blue coil in that ad.

 

I'm gonna stick with my new Bluntech coil and use my OE red as a backup.

 

I tossed out a blue coil (came with car) last week. Nobody wanted it

Set the engine to TDC make sure rotor is over cylinder #1.  Do the green light thing then manually advance it a few more degrees.  Try cranking it.  Advance it some more until it fires.  Once idling set your timing manually with a light to match what is set for your curve at that speed.  This assumes all ignition wires and components are wired and working correctly.

Try pulling your tach wire off, and fire it up.  Happened to me, and one other guy that gave me a giant snickers bar for solving his problem.  A gremlin in the tach wire shorts out the negative signal from the dizzy to the coil, so coil has no idea when to fire right, and can be intermittent.

For the proper troubleshooting of this, you can put a 12v Test light on the black negative wire between the dizzy and the coil.  It should flash everytime the coil Is told to fire.  In my case, it was a dull constant glow until I pulled off tach wire.
