Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.

Hey how are you

with me we have to start fresh , i m not sure based on what they told you to change that .

the solid red light , means alarm is triggered on !
you will need a factory scanner or equivalent to run a diagnostic scan & retrieve fault codes from the alarm module in the vehicle.
is it the module, the receiver, hood switch , door switch, wiring etc.. , it could be number of reasons & there is not a fuse or a relay that you can pull out to disconnect it unfortunately

did you have it scanned?

did you try a master reset ?

was the ckp sensor ,plugs etc changed because of the flashing light ?

Please let me know

Thank You

I had a mobile locksmith come out and he couldn't sync it. he pulled codes with his scanner. u100, b2013, p1610,p1614. I haven't tried a master reset. do you think it will help? I changed the plugs because the was bad looking and I already had them out. ckp was changed because I was frustrated and took a chance because I didn't see a tach reading.

Hey there, thanks for the question.

I am very familiar with most these codes.

Expert:  Jake replied 2 months ago.

Do you have the complete CAN code? because I know its not U100

Expert:  Jake replied 2 months ago.

it's probably a U1000 or U0100 code instead. Would be helpful to know which.
