what year is the van please ?
now that Iread 'ecu cable-strapped to intake snorkle' it's soundinglike
a 1.9 wbxr.
Do you need a proper ECU mounting bracket from a 1.9 wbxr vanagon?
I still go for the Remote Starter Switch test right away .. ( like inthe
fist 4 minutes of 'starter-seems-dead' troubleshooting.
It takes the whole rest of the car out of the picture ..
Gets it down to just battery, starter, battery and ground cables,
thus eliminating and bypassing numerous possible weak areas.
Helps you know where to look for the real problem
'stubsitute and bypass' is a very useful diagnostic strategy often.
dig out your remote stater switch is my suggestion.
