Starter test good +jumper on starter barely cranks over? What's wrong

Yes even bypass wire by putting jumper right on starter terminal, like mentioned above. Battery is weak but with jumper & jumppack should be getting enough juice. Thanks

take starter to AZ,have them test 3 or 4 times.then ask them to pull new starter off shelf and test it,see if they sound the same,and take your battery with you and get it charged.

Good idea but 50 plus miles to AutoZone, Napa ran test 4 times first failed cause bad connection it passed next 3? It also spins on car jumper ground of course. Battery on charger will put on battery analysis Monday. I seen this jumper pack start other big motor with total dead battery. But trying to eliminate any simple problem surely seems like something is making it hard to crank.

okeydokey,post results.some starters come with shims!just a thought.reman or new starter?

Sorry if I gave impression I was replacing starter?

like to know if they got it fixed,been 2 weeks since last reply!

Thanks abe305 I just got word from tech its a broken rod something internal? So picking it up. Found engine cheap but saying it needs to be a 08 the 06 $700 etc I found not a direct match? 08 are $1800 plus with twice the miles!So finding out if I can do the swap with some minor extra work. Or rebuild this one? Bought this hoping it be a simple fix lol
