start up fail help!!!!

El_supracabra · 03-16-2011, 04:55 AM

86.5 mk3 New/rebuilt engine is now installed, I triple checked all of my wiring and vacuum connections (per diagrams), filled it up with coolant and oil and attempted to start the engine.

GRRIINNNDDDD!!!!! *click* grriiiinndddd *click* it wont even turn over..
The compression ratio is about 10.5:1 with the milled head, MLS gasket, and decked block.

EEeeekkkkk!!! wtf?! I am a VERY meticulous mechanic. I do EVERYTHING by the book. I dont take shortcuts and I am a perfectionist. However, i do make mistakes....occasionally. ;-)

I had installed an aftermarket lightweight chrome-moly flywheel. The starter itself is only about 6 months old and worked fine before the rebuild. The battery is brand new and I also had it tested after it failed to start (hoping it was a "weak battery". no such luck.) battery tested perfect. I had also checked the nose gear to make sure that it would properly engage the teeth before i dropped the engine in. (although i couldnt bolt it up to the tranny, i pushed it into the mounting flange and pulled the gear out w a pair of channel locks to make sure the teeth would engage) It all seems good. Is there ANY other possible solutions? too high compression? Battery ground location? triple checked timing.... please help!

OH does anyone know EXACTLY where the battery ground is supposed to bolt up? *previous mechanic had it stacked on top of like 3 other ground on the plenum. didnt seem right..... THANK YOU!

The big ground wire that comes off the battery bolts to the side of the motor.

Are you sure it's not grounded to the chassis? Where specifically does it mount to the engine? Does it go on a tranny bolt? The block? The plenum? Please be more specific. Thanks!

It goes under the intake manifold to the block. Right behind the alternator. It is a 12mm bolt and it is grounded by itself!

Sounds like a bad starter man!

El_supracabra · 03-16-2011, 07:04 PM

Thanks for the reply! I went out today and moved the ground bolt to the correct location. I also took out 4 of the spark plugs and tried to turn the engine over with a big 1/2" ratchet on the crank bolt, it wouldnt BUDGE! it is locked up solid! I know that the engine spun freely before I dropped it in because I could turn the harmonic balancer by hand when I set the timing! After i put the timing belt on I turned it 360 degrees to make sure the marks would line up properly. So WTF?!

Also the clutch pedal feels spongy and soft. It doesn't feel like there is NEARLY as much resistance as there used to be. Could the clutch need bled? I didn't disconnect any clutch lines.... Could my aftermarket flywheel be the prob?

Thank you guys so much for helping this first time supra owner!!

Ouch! please tell me you used assembly lube?

Did u clean injectors before they were installed? i had a set of venom that one stuck open and filled the cylinder up with fuel! Pull the other two plugs and see if by chance some dirt or something stuck open the injector. It only takes one cylinder to hydro lock an engine!

Have u tried moving it both directions? I'm not saying rotate your engine the opposite direction for a whole rotation. Just see if it moves at all either way!

Travis89Turbo · 03-17-2011, 12:36 AM

And on the clutch thing. No a flywheel will not caue spongy pedal. Did you use a new clutch? And is it oem?

Could be time for a new slave and master cylinder!

Could just be a clutch pedal adjustment!

Are we talkin about a 7mgte?

Sonyps307 · 03-17-2011, 01:16 AM

I think it's a 7mge because he said it has 10.5:1 compression and that can't be for a turbo.

Sonyps307 · 03-17-2011, 01:19 AM

Take out the distributor then see if u can turn it.
