914World.com _ 914World Garage _ WOOO HOOO! My 72 starts

Posted by: Doug Leggins Sep 10 2004, 10:48 PM

Finally, I turn the key, hear the fuel pump and then she starts!!!

It has taken me 4 days to get it to start using the ignition.

Day 1 - change the ignition switch inside the steering column. Didn't completely solve the problem.

Day 2 - change the relay board. Solved the intermittent ignition operation of the starter but no fuel pump operation. Screwed around trying to get the fuel pump to work and smoked 2 Pertronix units

Day 3 - worked on the 73 because I was still pissed about the trouble with the 72.

Day 4 - decided that it wasn't going to get fixed until I got back to it. Put points back in the distributor, broke out the manuals and multimeter and started tracing wires. Finally figured out that the relay board had an 8 amp fuse in the fuel pump fuse holder instead of a 25 amp fuse. Changed the fuse, turned the key, heard the fuel pump , turned the key to engage the starter and it worked too! - the engine started!!!

I still suck at electronics but not quite as bad as I did a few days ago.

I've been putting up with this intermittent no start using the ignition (using the old screwdriver always worked) for about 3 years. maybe now it is finally gone.

Great Job at trouble shooting.

Makes me wonder why with all the parts that people has made to improve our cars. No one has gone and redesigned an updated relay board using updated parts, like spade fuses, modern relays.
