Bad EMS unit?
 
Alright guys well finally got my car finished up now it wont start... I can not for the life of me get any computer to connect to the ems and the car will not start.

It will turn over but the fuel pump won't kick in, when a battery source is hooked to the fuel pump boom it kicks on, also there is no spark.

We have replaced cam angle sensor, crank angle sensor, checked all relays for the pump and still nothing.

Seems like the ems is just shot? Im really out of ideas

Any ideas or thoughts??

Thanks alot guys!!


EDIT: Also when trying to connect it just says frame error, parity error, break error and it will never connect. I never had these issues before...

You need to send your ECU in. It sounds like a bad Eprom chip.

Mine had the same problem.

How much was the repair? Also any idea what caused it?

Yea it's a bad unit since some Honda techs were under the hood and shorted some things out.....lol

You need to check if you are getting 'Stat synced'. If it is 'on' and you have no spark/fuel, reload your firmware and try again. If that doesn't fix it, call AEM for an RMA and send it back.

If 'stat synced' stays 'off' during cranking then check the parameter 'timing error'. If the errors continuously increase while cranking you have a mechanical timing or sensor issue. If it stays off and you do not get timing errors then it is not receiving your crank/cam sensor signal at all.

try disconnecting/reconnecting your battery first before you send it back.
