While I'm pretty far from a guru, my car is having a similar issue. Been internet scanning and searching for days. Here's my 2 cents, which may be usless..

1.) From your pic, The upright "I" and "E" marks on your cam gears seem straight up. My manual (Rod's) says install".. "I" mark on the inlet cam a few degrees clockwise from vertical, and the "E" mark on the same pulley being a few degrees clockwise from the "E" mark and line on the head seal plate.

Exhaust cam same, but marks a few degrees anti-clockwise. Again, you pic looks to be vertical (could just be camera angle though).

2.) Still have the other EMS? Swap it (pretty sure you thought of it). Was the other engine running the same COPS? I guess what I'm trying to say is swap back to what you can to what worked before.



Good luck. Dont't burn it (yeah it's crossed my mind to..).

Thanks sixace...hope you get your issue figured out as well.... the marks align well with the "V" on the front plate which is the most accurate way of aligning the cam gears. I'm certain its on the money. I've done a few timing belts and so far so good.

Don't have the other EMS anymore...I actually traded it for this one because it matches my year car. The stock ems is the only one I have... and with different injectors/map sensor and AIT... it won't have a clue whats going on.

You know Alex; it may be worth trying to start the car with the OEM ECU and injectors.

Never mind, I remembered you have COP also.

Sorry man.

Just swapped my Cam Angle sensor for another one from my spare motor. Still no luck. I did have a little bit of luck by stopping and then hitting the key for the starter for a short period of time.

The only time the car seems to catch is right after I let go of the key, it goes for a couple of chugs then dies.

The vacuum line is connected to the MAP sensor (which is connected and configured to the AEM)

I'll lean out the crank advance table and see what happens. Seeing as i have no IACV, i've been cranking it with the throttle 5-10% open.

How would one check this??? I know they are all firing, hopefully in the right order....
They were firing in the right order before...are there settings in the EMS for firing order??? and what they should be...it is fired in batch right now.

Here's an update:

Alex took the AEM out of the car and connected the OEM ECU. The car started right up.

I don't understand what could be wrong. The AEM was working perfectly up until I took it off my car.

Can any of the AEM gurus (Jason and others) give me any other suggestions?

How can we confirm whether is working or not?

Thanks

I looked through this thread, but didn't see an answer to my question:

Have you tried another cal? While tuning my car initially, the file actually corrupted. This file was no different than my backup, yet, the car just cranked endlessly. After this girl and I tried to figure out the problem for two hours, I loaded an older version of my cal and the damn thing started right up. The problem was actually the file, I tried reloading the old cal afterwards and it just cranked again.

I'm almost certain you have tried this already, but try loading the stock cal that came with the unit.

Sorry I can't be more help.

Rafa, I'm assuming he also put back his stock ignition while attempting this. Could the COP's be bad?

Just throwing out ideas, I really have no experience in these things.

I'll confirm this... and sum a few things up
-The car starts great on the stock ECU but not with AEM EMS.
-There is no power coming from the coil 1 & 2 trigger outputs on the AEM ems (but there is on the stock ecu)
-I have Toyota COPs (not sequential yet so only using coil 1 & 2)
-Normally I would instantly blame the ecu but it worked in Rafa's ride with similar specs so it should work in mine as well.

Here is my AEM *.cal file to take a look at:
http://www.2shared.com/file/gKyHg9xr...buildV119.html

Please help!

I've tried about a half dozen cals included the one that came on the ECU, the factory cal from AEM and my last cal the car ran with earlier this year. Unless its the firmware or something along those lines thats off....I have no idea on that one.

I actually started the car with the stock ecu, no maf sensor, toyota coils and the fuel injectors unplugged.
The car started instantly, ran for a few seconds while it burnt up all the extra fuel I had been dumping in the cylinders and shut off when it was out of fuel.
I just wanted to plug the factory one in to try and see if I could get the coils to fire...and it worked, amazingly well I might add.

Alex, I don't know how to download the Cali form the site you posted.

Nevermind, I think I got it.

alright.... still no luck getting it to fire up.

Got it fired on the stock ECU and the engine timing was rock steady at 12btdc while reving at slightly under 2k rpm so I know there is no issue with the wiring or timing of the motor.

Went to plus the AEM unit in after that with the *cal file loaded from before and once again had no luck whatsoever getting it to fire up. There seems to be spark just not at the right time and nothing shows up on the timing light as it doesn't fire up.

Serious call out to the AEM gurus out there.... It seems to have no idea when to fire the plugs if its firing them at all.

EDIT: once again, here is my *cal file: Currentfromlastbuild.V1.19.cal - 19.9 KB

Alex; fooger's suggestion makes me think you should try to start the car with the regular spark cables connected to the coils as it comes from the factory.

We already know that your car starts up with the OEM ECU so why not try this?

Something is wrong with the spark and how the AEM is reading it but I can't figure out what.

Jason, any help would be much appreciated.

that does make sense.... If I still had a wiring harness for my coils and plug wires I would so try this.

its only 2 coils that are firing in batch so there is really only 2 ways it can connect... i'll swap the trigger wires on the harness and see what happens.

Right now spark plug 1 and 4 fire when i activate the coil 1 trigger in the ems settings
and spark plug 2 and 3 fire when i activate the coil 2 trigger in the ems settings
Does this sound right? or should it be the other way??
