Trying to make sure my ecu timing and cas timing are the same.

 

So got myself a timing light.

 

Tested it on an old guys Triumph that lives nearby and it works a treat.

 

I've seen a few different ways you use it with a coil pack system.

 

One way you rested the induction head on the coil pack, didn't work.

 

The other way, you remove coil pack, I then used a spare ht lead I had, attached an end to the plug, the other to the coil pack.

The car starts and runs on all cylinders, but once I connect the inductive clamp to the lead, still nothing lighting.

 

Can anyone help?

Can you rest the pick up at the back of the coil pack?

The further down the better.

I rested it on the coil pack, just like above, I didn't use a cable tie to hold it open like that though, I will give it a try tomorrow and report back.

If it is not held open it will not work.

Just tape it open :)

Isn't there a timing loop just downstream from the PTU?

OK so tried it today with the head held open, same issue, not picking up a signal.

 

Got me stumped now, as everything that works on other peoples cars, isn't working.....annoying when that happens!

Check and clean your connections, make sure you are getting a good earth.

Maybe try several connection points?

Tried that as well mate, connected to the point Jeff mentioned, same problem.

 

Going to try and get another battery and connect it to that directly, then try again.

 

So annoying that it worked straight away on an old Triumph!

Mmmm puzzling.

Can you try it again on the Triumph?

The only reason I say that is that it may have developed a fault since. (the strobe that is)

Also, as Andy says, try the timing loop (a little loop of black wire to the right of the PTU, clamp closed)
