Hello! So were you driving when the battery light came on? What did you use to test the battery and is it an individual click or multiple clicks?

Customer: replied 1 year ago.
Was driving when the batt light flicked on and off, single test of batt. one click only with all the light going out when holding the key in the start position
Expert:  Roger replied 1 year ago.

It sounds like a bad connection on the battery or one end of the cables, an individual click under the hood is usually the characteristic of a poor connection. Does it still have the factory cable ends at the battery on it?

Customer: replied 1 year ago.
has factory cables, acts like the starter is pulling full power but the starter sinolid (sp) wont engauge

Have you tried turning the engine over by hand with a long ratchet?

Expert:  Roger replied 1 year ago.

If it is clicking and you have a known good battery and there is no poor connection its possible the engine is seized. Try turning it by hand.

I will try it tomorrow also wounder if a bad alt could cause the problem/
Expert:  Roger replied 1 year ago.

It could cause the battery light to illuminate, but it will not cause a no-crank issue

What size is the damper pulley bolt?
Expert:  Roger replied 1 year ago.

I'm not sure off the top of my head but I own a truck with a 5.0 liter, let me take a look and I'll have a good idea. Be back shortly

Expert:  Roger replied 1 year ago.

My truck has a 21MM damper bolt, keep in mind however it is possible yours may be different.
