Ok i got code 11 i just did a motor swap and now i get this code the motor runs for about 11 secs and then shuts off, sometimes it backfires and if you touch the throttle at all it shuts off. I have no idea what this means it says its something to do with power to the ecu interuption bad main relay, ignition switch, ignition, or ignition relay how would i test these so i kno how to fix this..
Code 11

Be sure to check all the wiring connectors , Could be a bad afm connection ... Or not even plugged in at all
Does it run good , or, shitty for the 1O secs before it dies ...
My car would only try to start , Then I get the code 11 , Also
I fixed all the wireing problems , Aswell as the faulty CPS ...
Good luck.
Check all of your grounds. Partticularly the one under the intake manifold that is where you ecu grounds. A code 11 also lets you not see any other codes until its fixed.so you need to fix that before you can see if anything else is going on.
ok ill make sure to do all of those things my afm is plugged in, and ive tried two cps's the wireing didnt look bad on either , ill deff try the ground thing i didnt know that could cause a code 11 and not show any other codes, it runs great until it stops running lol. thanks for all the info

I learned that from you
When I had to rewire my entire harness beacuse I bought a hacked one. But it works perfect now
Theres lots of grounds to check ... Coil packs .. 1 near the starter , 1 near the top left side of the fire wall , igniter ground, fuel pump relay ground .... Look for bad corroded connections also ...
you may wanna check the fuseable link in the fuse box under the hood ... It could be on its last leg ... Ive had to replace every one Ive came across
Good luck & I hope you get your supra running better .

Solid grounds are always a good thing. However, for a code 11, the most common issue are the grounds that attach to the intake manifold as previously posted. Those are the ones that directly affect the ECU.
