Someone help please??

For a while now my truck has been starting slow. Youd have to hold the key for about 4-5 seconds before it would actually start. I figured no bog deal, batteries probably need to be replaced. Had to jump it on Sat, and checked the voltage, which was 14.5 on each side, so i know my alternator is good.

Bought 2 new batteries, just installed them, and truck still wont start. Even with the new batteries it barely turns over? The terminals look good, and none of the wires appear to be corroded. Any ideas???

Ok you guys are ZERO help

I took the starter out and had it checked, its good. Not sure where to start now?

OK, how did you "check" the starter?

What about All the cables? At this point, if your batteries are good and your starter is good, I'd be thinking cables...

ALL ENDS (both sides, + & -) should be scraped - cleaned - greased - tightened. Look for the "green crud" in the wire and ends, if it's in the connector, you might have to replace it.

Could be a few different things. What is the voltage before you try to start and what is the voltage when you crank it? Get the voltage from a few different points, at the battery terminal, the cable connected to the battery and in the cab.

The starter was bench tested at Advance Auto...it passed with flying colors and actually drew less amperage than a brand new one we tested. It also only took 11v tol turn it, while the new one required 11.5v.

I will check the cables now on the starter end. Prior to cranking it, my batteries are at 12.5v. After trying to start it, the voltage is still 12.5.

Another suggestion i have gotten is the ignition module, the one the little red wire that comes off the starter goes to. My buddy works at Goodyear and said i can bring it up there tomorrow and those guys will take a look at it for me

Ok update........now i cant even jump the dang thing. This is probably something simple, but im gettin so irritated trying to figure it out! I think tomorrow im gonna replace the cable that goes from the battery down to the starter and see what happens.

Check your glow plug relay. I had similar issues a few years back and that fixed it for me.

Check to make sure you have power to both posts on the relay while the key is one. If not, its the relay.

[mydirtytruck]

Thanks alot, i will check both of those and see what happens. Anyone else have suggestions?

[mydirtytruck]

Ok for all you guys who had ZERO suggestions...the problem was the starter. I know i know, i took it off and Advance Auto tested it, shows how well their equipment works. The 350 is back

The only thing I trust them with is to give me the part I ask for myself.
