does the starter GRIND as in whine...

or does the battery and starter just whine???

measure the battery voltage with a digital volt meter..  

turn headlights on for one minute.. then turn off...

12.65 is a fully charged battery

12.45 is a 3/4 charged battery

12.25 is a half charged battery...


measure the battery voltage while somebody attempts to crank the engine... does it drop below 11 volts????? it should NOT..

measure from the Negative battery post to the engine... have somebody try to start the engine.. less than 1.0 volts is good..  0.5 volts is better..

measure from the positive battery terminal to the alternator output stud...   less than 1.0 volts is good..  0.5 volts is better...

i am having you measure from the alternator output wire instead of the starter solenoid top wire as its really hard to reach...

1.Just my 2 cents: Sometime if not most of the time, when the starter has been replaced, on the long end the heavy end of the starter there is a bracket.

2.The bracket is to hold the long nose end of the starter in place...  sometime the technician will remove it. Because it is a hard to install thst big starter and thet bracket be in the way.

3.Think about it this way. There are only 2 Bolts holding that 18"long 20lbs. starter, to the engine block,(1) so your going to play around with a bracket. Nope!

4.Everyone sees what I'm saying! Over time the bumps in the road and there are many times you start the engine, there is a small aluminum housing with a brass bushing in it. Well all the banging around that starter took with no bracket (BRACE)over those years finally killed the starter.

(1)The 2 little starter bolts are a special style bolt, and some are a special length. I can tell you this they are:
  3/8"X16 thread sizes could be 3/8"X16 1X7/8"
or 3/8"X5/8" 4"X5/8". They are also knurlled on the end threads. Any one thats been around small block chevys should know that...lol...

Before going to the parts store pull # 1 and #3 spark pulls and look at them very closly. If #1 is sooted and foul looking . I would consider buying a set of spark plugs for your truck.Also look at the boots and check the ignition wires, they maybe cracked or dry rotted. Good Luck

Nicktip1 go for a complete tune-up.
It could be an accumilation of faulty parts...

So you want him to do a complete tune up on a motor that won't start?

Can't we diagnose the no crank problem first?
