Welcome, I'm Chris (aka Moose). I'm here to help 365 days a year, but not every hour of the day. I try to prevent delays as much as possible. Please understand I am not there and can only advise based on what you tell me. Let's get started.

Remove the starter relay, are you always getting power on pin 30?

Are you getting power on pin 86 when trying to start with the key?

Are you getting ground on pin 85 when trying to start?

When trying to start is the PCM showing a start request?

Customer: replied 2 months ago.
No dealership #$=% it up they never did a reset on pcm after refreshing it so no further help is needed and if I could plz get a refund only finding out it's in American dollers w$# 42 $ latter thanks but no this 42 dollers is going to have to go to the dealership to fix this one.
