Help... fuel pump relay or CPS??
Short of the long...
Car didn't start no check engine light , but turns over... pulled codes via Durametric. Fuel relay, CPS bank 2, a misfire and an 02 sensor. I felt that since I only had the car 5 months a few could be old. I caused 2 during a tune-up.. relay and misfire
Ok.. so I jump the relay bam ... it starts and zero codes after 15m. There aren't any strange noises and the car runs fine.
So I buy a relay ... plug it in ... boom no start. I jump it again ... fires right up.
Could it be a bad relay? Or is the relay not getting the signal? Can I test this?
Ps. Porsche sells a great relay jumper.
