No Start!

1

I have a bit of a puzzle.  I have been running one of Hartmut’s distributors but had to send it back to him to get Peter out of trouble.

I installed my old distributor with a new Hall sender.  It will not fire, let alone start.  Spark is OK, tested on a plug while cranking, so I am at a loss to know why I now have no firing.

Any suggestions welcome!!

Maybe 180 degrees out?

Very easily done and when installed that way it doesn't sit in properly and doesn't turn.

Or the drive dog was fitted to the shaft 180 degrees out. I would go back to basics and get number 3 rocking and make sure the rocker arm is on the grove. Then make sure your leads are in the right spot. Greg E

OK, everyone back to their own beds!!

I have just taken pole position in the Dopey GT for 2015.

To fit the Hall sender, I had to dismantle the distributor.  On reassembly, I had indeed assembled the dog drive 180 degrees out!

Dopey, dopey, dopey, dopey!!!!!!!!!!!

Scott,

The next problem to solve is intermittent cutting out.  It will either cut out completely (complete loss of a signal to the ECU) or cut out for a few seconds then resume running.  This can happen at any speed.  Since it was happening on the borrowed distributor and on the newly re-fitted original distributor with a new Hall sender, it is probably safe to say that it is not the Hall sender.

I will go through the Digifant manual to see which senders will shut down the ECU if they fail to send a signal.  The Hall sender is certainly one of them.

AIR FLOW SENSOR can cause this. The carbon track gets worn. Old fix was to add capacitor across pins 2&3. If that doesn't work you have to move the wiper inside the sensor. This fault (and fix) well described on the USA syncro site.

Peter, you are a couple of days behind with the postings. As already posted, I caused the problem myself by assembling the drive dog on the distributor 180° out of phase. Old brains like mine experience fade from time to time!!

Peter,

Yes indeed, and you were referring to the intermittent miss problem.  Sorry, my brain is now more online than it was when I answered your previous post.  Sorry.
