I had trouble starting the car today... the fuel pumps didn't come on, so I was told to reset the AEM by unplugging it and plugging it back in, and the car started. However, I am wondering if I will have the same problem again in the future, and if I'll have to send it in to get it fixed. Thanks in advance.

 

Anyone? I thought this was somewhat common issue on some EMS's... I guess not.

 

Rookie,

I have never encountered the issue but if it happens again keep the key on and verify that the EMS shows its triggered on this may help you narrow down if it is the EMS or the relay under the hood starting to fail. Just a thought, good luck.

 

if you want you can check in output setings Ls options

 

In the output setting. Make sure to set the lower temp to -32F so it will activate the pump.
