Re: New to me 15' REX Certified Pre Owned no start REX?

You should change the fuel pump relay under the glove box. My i3 had the same problems until I changed it myself.

Never had a problem since the. The relay cost roughly $35.

Re: Ugh. More misfires. (Drivetrain error)

Mine does that all the time! It looks like all the first generation i3 with REX have this problem.

Doesn't seem to be a big problem since the check engine light will go off after a few starts.

Re: Ugh. More misfires. (Drivetrain error)

I had this problem too. It was the fuel pump relay that was defective. $31 for the part. 15 minutes to change by removing the glove box.

Everything runs fine now.
