After having done a conversion a couple of years ago and spend a lot of hours trying to trouble shoot "weird" startup problems it turned out that to be a poor ground connection between the battery ground terminal and the engine block and ultimately the ECU. The way to test this it to use a #12 wire with a clip on one end and a probe on the other and run it directly from the ground post on the battery to the ground pin in the harness. then try and start. if it works it is likely a ground connection problem.

Hi, Mike.

Sounds like a frustrating issue.? Have you double checked your ignition switch to rule it out?? They are prone to intermittent failures.? Search The Samba if you need help testing that or here's a link:
