Won't start, won't turn over, acts like no power to starter. All other electrical works. Had battery checked, replaced starter relay, and replaced starter-still nothing. Any ideas?

So it won't turn over at all?
If you have an ampmeter try puting it around a spark plug wire to see if you are getting amps. If no then try puting it around the starter, see if you have amperage going into and out of your starter.
basically wherever you have amperage going into, but not coming out of will be what has failed.
Also another thing it could be is your battery.
Just cuz you read 12 volts doesn't mean the battery is good, it may not be putting out enough/any cranking amps.
If you hook jumper cables up to your truck from another car does it start?
If so your cranking amps and battery might be toast.
I know Kragan has a tool they can bring out to your truck and they can test your whole starting system including battery cranking amps.

Jump starting didn't work, and the battery was tested on a machine. With everything that I have replaced so far I was hoping someone might have an idea of what else could be wrong.

Have you checked the alternator?

If the starter won't turn, check all the grounds.

On my ol '89, it wouldn't start sometimes, the ground from the battery to the block was messed up, i'd have to jiggle that ground. All it would do is click, until I reset that ground.

First off-Thankx for the replies. I checked everything twice and finally took the NEW starter out and had it checked, it was bad of course, put another new one in and she starts. What a pain
