Need help fresh rebuilt motor cranks but wont turn over
 

Alright in need of some help here got my motor rebuilt in my FD (motor didn't blow just was looking for more power and preventing it from blowing up stock 50k mile single turbo) it's single turbo gt35 with a full bridge port sake bomb aem smart cool setup areomotive 340lph fuel pump id1000 primary and id2000 secondary's and all the emission stuff is deleted and what not and I'm running a adaptronic pnp ecu I got a base map from turbosource and everything is hooked up and I'm getting fuel and spark but it won't turn over just cranks and cranks can anyone help me?? Need this done so I can take it to h2oi next week I've been in touch with a guy to tune my car this week but just seeing if anyone has an ideas here

Remove and clean plugs(install new would be better), perform deflood procedure with plugs removed, remove UIM and put a cap full of oil in each LIM runner. Reinstall UIM and plugs, start the car. If the car does not start and you have fuel and spark you have very very low compression.

When you say you have fuel, have you verified injectors are actually spraying?

Yes injectors are squirting I'm thinking that it might be flooded right now if it's not that I believe it would be timing or bad map sense it's a fresh rebuilt motor so I can't see it compression already and if that's the case id be one very unhappy customer lol

Is the ecu set to internal map sensor, and the vacuum line hooked up to the plenum? Can you take a log of the no start condition?

I would squirt some oil in the leading holes after deflooding and try again.

I have a log that I sent to Mike at angel Motorsports but hasn't gotten back to me and I do have the vacuum hose hooked up as well

fresh rebuild is not going to tell you if a seal is jammed....... :icon_tdow

1st step is always to do a compression test no matter the mileage
2nd test spark
3rd fuel. What pressure reading are you getting?
4th Read the ecu manual. Its in the ecu software under help
Make sure your tps is setup, trigger and injector settings are right.
if your tps reads over 300 your butterfly might be way open inspect it .\
A base map dose not mean it 100% set to your car.:fingersx:

Pull the plugs and egi fuse and do a deflood you should see fuel vapor if its flooded. also if your cranking for a long time and you feel its flooded you can hold WOT and the ecu will fuel cut

With the AEM coils, I'd be double checking all the extra earths are attached to the block - had the embarrasing moment when a couple were overlooked and the bloody thing wouldn't start!

post the datalog

and while you are at it email it to the Adaptronic tech department;

tech@adaptronic.com.au

Is there any kind of "master fuel" adjustment?
If so, try adjusting it down slightly untill it starts. Obviously dont drive it without a real tune though

$10 bucks says engine isn't spinning fast enough to generate enough CAS signal for the ECU filter

This was my issue on 20b + Adaptronic



Whether this is your issue or not,

Run a large 0 or 00 gauge wire directly from your battery to the starter. Directly. Cranking RPM's will blow your mind. Everyone with an FD should do this

Are you using the factory Mag sensors? If so are you sure that they are plugged in properly? They can easily be swapped and will wreck hell on you RE: ref vs. sync.
