i just put my engine back in my tc last night after boring, forged pistons, rods, valve job, balance shaft delete, and all i get is a putt putt putt from the motor. the battery is delivering juice (relocated to the trunk with 0awg gauge) this is a custom forced induction motor, both previous and now, its running off a emanage blue and its working right. any suggestions?

 

Get rid of your emanage blue and search there have been a lot of threads with your situation. Look through it you might find something.

 

Won't start or won't crank? What did you do for grounds?

 

my friend has a similar problem he took the motor out and relocated battery to rear, once all put together the light would flicker and motor would just putt putt putt but not turn over.

after like months and a millions other ways to fix it.....it was a ground issure with the battery..so has to d something with the grounding of the battery

 

step 1 . grounds

 

make sure the battery is grounded, and the engine is grounded to the chassis....i always see customers forget to ground the engine....

 

Customers were do u work?

SECRETS!!!!!!!!!!!!!!!!!!!!!

^^lol..priceless

 

lo out of my buddies garage i thought i told u i used to work on supras and lexus.... oh well those days are long gone im jobless

 

^^lol

 

The battery is grounded twice with a 0awg and a 4 gauge. The engine is grounded twice with the same. Locations are both sides of the valve cover. This is driving me crazy

 

And it won't crank. The starter is turning the flywheel but won't crank. Spark are good and grounds are good. Also getting fuel to the injectors.

 

u didnt ground the trans... thats where u should ground... anyways alot of ppl with thte 2az after building wont crank over becaus eof the cam sensor

 

Or timig chain. Bro it can be so much. You should look into the service manual! Just look through all the pages that show putting back the motor togeter and it will show you alot.

 

If its turning, getting spark and fuel like you say then its the timing chain....and that seems to be the case 99% of the time on SL with engines that wont fire.

 

check all the spark plugs, mine were covered in oil when i started mine up lol

 

just found out my throttle body is blowing air instead of sucking in air.. def the timing chain... thanks guys. is there a quick thread that will lead me to a diy timing chain lol

 

Yup that was my problem.

 

what....what

oh yea...that was my problem bahaha....just check your timing on the cams first so you dont have to pull off the timing chain cover.

if you want to know what the cams should be set at....search for a thread by yamaha....best pictures of it.
