Hi,
I got a trouble yesterday . Everyday, the car always starts right from the first time i turn the key, yesterday was no exeption. I drove very few , engine was style cold, I parked in a garage, cut off the engine. Then 1 minute later I wanted to fire the engine again to move the camaro : the engine never started again! The starter does work, but there is no spark at the spark plugs any more. We checked a lot, the coil is still OK, battery of course OK as the starter works, what is suprising is it seems everything is working very well cuz the engine runs really good. Till yesterday ! the electricity is custom and it is a mess ! too much wires , there are 7 wires that connects to the coil, …. I really think a connection must have become loose or something as stupid as that…. Any suggestions??

It would help to know a little more about the car Year, engine cid, type of ignition, and what the heck the 7 wires are going to ?

I don't know about the wires, i bought the car last year, i am learning to work a little on it, the ignition : 6AL MSD ignition box that doesn't seem to be connected, Malory elecrtonic distibutor + MSD coil. 327 cid from '64, rebuilt in '86 with a 4150 holley 600 cfm, HE268 comp cam, hooker headers.
it is a mess of wires, though in good condition, there was a lot of gauges on the car.
I'll take a look at the wiring this w-e with a friend.
Any comments appreciated but i understand it is hard for you to guess what it is.

Something quick and easy to check would be the wire running from the coil to the distributor. If it has become frayed or dislodged that would kill all spark. Check wire running from coil to starter. Sometimes they have a fusible link in them that could have popped. The wire may have fallen off the starter that runs to the dist or for some reason burned into. Never know, but those would be easy fixes for no spark.

Is it an automatic? If so, make sure it's fully in 'park'. With time the linkage gets sloppy. Also check the neutral safety switch.

hey it was the MSD ignition box , 6AL unit that wasn't working anymore. As it acts as an amplifier (and also from 1 pic create several pics : multi spark below 3000 rpm) it receive 12 V on input and delivers 470 V on output . the MSD coil than only function with 470V on input. it is built to work with the MSD box.
So we had to buy a new standard coil that do work with simply 12V on input.
Now the engine runs again!

But.... MSD says there IS a fuse inside the box (6AL) and say it is useless to use a fuse in the wiring, so we though that fuse inside the box might be burnt, and we tried to open the box. After some hard tries (everything was done by MSD so that you won't open the box even if you want it! ) we eventually succeeded opening the box and removed the electronic circuit.
Guys, there is NO FUSE inside that box! capacitors, resistances, coils,...and everything is covered with a plastic paper so you can't check anything. but no fuse!

So I do recommend you to install a fuse on your MSD wiring! to avoid burning it like it happened for me!

No i'll drive the car a little (winter is coming) without the MSD unit to see if i can feel any bad changes.
Was it bad luck or are there other people who got reliability problems with their MSD ignition boxes?

Anyway if I buy another similar ignition box, I’ll add a fuse !
