Re: Stus-List Starting Problem

[Sam Salter via CnC-List]

I second or third the ground!  Had that problem for a few years. Engine was dead on the start button, until 3rd or 4th press and then would fire up suddenly. (2GM20F) Bad ground to the trans. case. Cleaned it up and all was fine. I eventually replaced all the battery cables with pre made  cables and ends from Canadian Tire.‎ After 35 years all the wire to end joints get a little suspect and the wire was not that good to start with - not tinned! Fore something like $35 and an hours work, I now get instant starts every time.  sam :-) C&C 26 Liquorice  Ghost Lake Alberta  From: Dave Syer via CnC-List Sent: Monday, June 6, 2016 9:05 AM To: cnc-list@cnc-list.com Reply To: cnc-list@cnc-list.com Cc: Dave Syer Subject: Re: Stus-List Starting Problem Check your grounds.   Had what I thought was a dead tach  and it was a corroded ground connection where the main harness from the engine control panel grounded via a ring terminal on a stud to the engine.   This should be a maintenance item...
