I had what I thought was a flat spot on the starter about a month ago.
The solenoid would kick, but the starter wouldn't turn over. If I
cycled the ignition switch a few times, it would eventually turn over
and be ok for a few days. Then a repeat... I replaced the starter
and had no problems until a couple of days ago, when the same problem
popped back up. This morning it got even worse. After cycling the
ignition a few times, I could hear the starter try to turn over, but it
dragged, briefly, followed by the entire instrument cluster going dead.
Now the solenoid won't kick in either. My first thought is that I
blew a fuse or fusible link.
How is the ignition circuit protected and where do I find the fuse or
fusible link? (If it's other than the fuse box)
In doing some research on the web this morning, I came across some
references to ignition switch problems on chevy/gmc vehicles that cause
some crazy electrical problems. Some other problems I am currently
having, but have dealt with up to this point are incorrect readings in
the instrument panel. Voltage reads only about 9 volts (occasionally
jumping to appropriate levels) most of the time and the fuel guage
reads near full until the fuel level in the tank drops to just a couple
of gallons - where the guage will drop to empty. I've assumed, and
have been looking for, ground problems in the wiring to correct these
problems but now if they're all related to a bad ignition switch,
including the starter problem.
Can anybody help?
The motor is a 350 and mileage is 180K.
