Car won't start turns over fine but ecu dosent seem to be getting power what could this be please help

 

can you be a little more vague? please?

 

why do you think the ecm isn't getting power?

 

I was driving fine stop at the store came back no it's just turns over check engine light stays on but ecu dosent flash when turn into acc main relay dosent click put on a new no sound from it out of no where this happen

 

firstly, check/clean the thermostat housing ground.
if that's good, you need to check at the ecm for power and ground.
you should have 2 powers, one constant, and one keyed. and i believe 3 grounds. find a pin out for your ecm connectors and check for the powers and grounds

 

Thanks bro it was the alternator valve fuse

 

It's nice when it's something else that wasn't told to you. Open in charging system is an open to startin and getting power. KISS keep it simple stupid El

 

hmmm. not sure how this would cause the mfr to be inoperative while still having enough voltage to crank. or what even what an alternator valve is, for that matter. but maybe our little pet parrot over here can tell me
