Hi all,

I have a 99 GMC Suburban with 113K mi. Drove home from work last night, parked it in the garage like I always do. Jumped in the morning and ....... click was all I got when I tried to start it. Everything appeared normal (no codes or extra dash lights).

I have replaced the starter (old one was turning hard but would turn).
I have checked the battery - test OK
I have tried jumping it - still just clicks
I have checked all engine and ignition related fuses on the internal and under the hood panels - all OK

Would an ignition relay failure cause this? I am scratching my head...

Thanks,
Tim

After researching previous posts I have learned that this symptom is common with Suburban's.

The quickest fix I found was to clean all contact points between the battery, starter, engine ground, fuse panel, etc.. I did that and it worked for me.

Thanks to all who suffered through this problem in the past and were kind enough to share what they learned.
