cranking issue! need some help

[roxypro53]

alright well i just rebuilt my motor and just installed it a couple days ago, when i crank it over it is slugish like it needs more cranking amps or something? i just recently purchased a new battery and still having the same problem. it wants to turn over but seems like the starter isnt strong enough. any ideas??? thanks.

have your battery tested if it tests out good check the voltage drop from the battery to the starter while cranking double check for loose conection at the starter and the batery and make shure you have solid grounds going to your engine

alright i just got a red top altima today so it is good and the starter is good also cause its basically new. but now when i crank it over the starter starts to smell like if its being burned out cause it cant turn the flywheel.

It could be ## starter where did u buy it from?

Yes it could be the starter but first measure the voltage AT THE STARTER TERMINALS (not battery) while cranking. If you don't have more than 9.6v then you have a high resistance cable or cable connection (would then need to clean both ends of both large cables and retighten). Also make sure you have a large negative cable going from the battery negative post itself to a starter mounting bolt.

ok will do and give an update on how it goes. thanks.

Does the motor turn on?? If the motor doesnt start up at all, its probably not a starter issue, its more likely due to the motor causing too much resistance which is why the starter is burning up?? For example: timing could be WAY OFF and you're mashing piston with valves together which = resistance. Starters dont burn up easily, usually they have broken teeth or the dont engage with the flywheel at all.

Seeing that you just had the motor rebuilt, try taking the spark plugs out and use a 17mm to turn the cams. If it turns manually without enormous strength, then move on to removing the starter and testing it outside the vehicle:

ok well i bought the starter from autozone and it is a duralast one and i have a couple of oem 1's sitting around and i swaped a couple and still the same problem, timing is on point but it seems when i crank it by hand it has some resistance when 1,4 or 2,3 drop to the bottom and start to climb up ( thats without the plugs also ).

- i think ill end up pulling the motor and see whats going on with the pistons and why there is so much resistance when the pistons climb the walls.

 

[luv2rallye]

Before pulling motor, put at TDC and remove timing belt. Then with plugs out turn crank by hand to see if resistance is still there. If not, resistance was in timing belt or camshaft/valves (so you may only need to pull head instead of entire motor).

BTW I assume you lubed the cylinder walls before putting pistons in and head on during your rebuild.

 

[roxypro53]

alright well i pulled the timing belt and there is still a little resistance like if the plugs were still in and still some struggle on the piston climb,. i did lube the walls and it has new piston rings as well. my guess would be the rings that is causing the friction? it sounds like the rings are scraping against the walls but not like usual. you can actually hear it.

Big mistake biying the started in autozone their parts are rebuilt and wount give u ## money bak I had a starter problem on my car also a few weeks ago and decited to buy one from oreilly's saw a major difference their starter cranked like it supposed to and took the autozone starter bak and told me their starter worked that it was good and they dint want to change it for a new one or give me my money bak but never buy from autozone I recommend oreilly's plus their starter is a bit more heavier

 

[roxypro53]

well i guess it wont hurt to pick one up from o'rieleys and slap it on real quick. but im sure its going to do the same thing if i tried 3 already, im just going to pull the motor and see whats up with the clearances.

 

[Dsm304]

Well I was just saying not saying u have too ### it happened to me I had verry low cranking even with the new duralast autozone starter :/

 

[roxypro53]

ya i deffently hate buying major parts from autozone, no wonder y they put there parts under warranty cause they know that in a couple months it will give out. i just dont want to give up on my dsm cause i know its a simple fix but some dam major work.

 

[Dsm304]

Yeah and their parts are remanufactured or something like that :/ and im having problems with mine also I fixed the alternator now I got water on my head im praying its just the gasket that popped ill be opening it sometimes this week haha

 

[roxypro53]

well good luck to you and your adventure dude, hope all goes well.

To be honest, ive never really heard too much problems with autozone's starters. Ive only heard horror stories about their altenators due to our turbos being so close. But anyways, thats off subject.

Im going to guess either:

a. the rings are improperly installed
b. the crank main bearings are improperly installed.
c. the tolerances on the bearings are off... wrong size bearings?

Im leaning more towards option B only because i hear about this happening more and more frequently and the main bearings are capable of being put in the wrong spots whereas the rod bearings are universal to location. Pull the crank end caps off that hold the crank in place and check for scorning or friction. Also, you can check the oil for metal shavings flakes. Especially since you had the motor already trying to crank over with the starter, im sure there was alot of friction. Fine Metal shavings in the oil would be clear sign of bearings grinding.

If it cranks over real slow or just clicks when the key is turned, it might be lack of a trans/starter bolt ground. I had the same issue last night. 4ga power wire to the starter, and it would just click or crank extremely slow, then start like there was no issues. I added the factory ground back up, no issues at all. BTW it was a new WorldWide starter.

He has motor issues as stated in the previous post.
