Hello two days ago I went out to start car and cranks but wont start.Car ran perfect from Buschur's Last Friday 600 mile ride home.It has rained here alot car was sitting outside.I checked all fuses under hood and under dash,all good.I also check powerpoints at AEM 12 volt power and grounds,also check cam and crank signals,all good.I plugged in my lap top no communacation at all.Is there a internal fuse inside AEM that could have popped due to wet weather??I have checked all over and every conection is good.No fuses are blown??Still no communacation with laptop??
I check all these things with my vantage snap-on tool.If anyone knows please help just dropped 26,000 at Buschur's and I love the car everytihng is new.The AEM is a year old.
Is there a fuse inside AEM?? to protect it??

 

If you just spent 26,000 at buschur he should come to you to fix it.

That would be the ulimate customer service!

If you really don't have any communication then the EMS may crapped out. If you really have tried everything you say. Then send that EMS to AEM next day it and they were pretty quick getting mine turned around.

 

Thanks, I did check everything,all fuses are good grounds and powers tested them all at the AEM.I really don't want to break the seal on the AEM.If there is a fuse inside it I bet that is the problem.
I have spoken with David I'm sure he will hook me up.he is a great guy.

 

It sounds to me like you lost your map. It is a rare annoyance but it is a bug that AEM has. I have only ever lost a map once, and I have no idea why it happens.

 

Try disconnecting the unit from the harness and plugging it back in. No communication with the AEM does not automatically mean there is something wrong with the unit. Give some more detail about how the car cranks. Quickly, slowly,....
Have you tried giving it partial throttle... Give us some more info

 

Thanks guys got the AEM back up.I did the reset thing and reloaded map.I installed my AEM in another car is working fine.

 

so what caused it to happen?
