Re: GM J39021 Injector tester
Posted to Tool & Equipment Forum on 11/9/2012
Hi Martin,
Thank-you for the information. I should have that tool but
it isn't in our tool room and no one knows the last time it
was around. I am working on a 2012 Silverado but I'm testing
the Exhaust diesel fuel injector as per Doc# 2890789. Which
only says to use J39021 tester and only gives flow results
but no time frame. I assume that tester has a set pulse time
for its inj. test but I can't find anywhere what that time
is.
