Hello , sorry for the delay. The fault is with the fuel pump assembly. There is a fuel tank pressure sensor that is most likely your fault. The car does not have a fuel pressure sensor , if there is a fault with the system it will not perform all the other tests needed for emissions. Hope this information helps Please take a second and click the box and rate my service GOOD OR EXCELLENT SERVICE if you feel I have been helpful and please request me in the future. If you feel I have not been helpful please DO NOT RATE BAD OR POOR AND WASTE YOUR MONEY , I will opt out to see if another expert can provide more or better assistance so you're not wasting your money!!. Thanks for choosing just answer. Lou. also , if you feel i deserve one , BONUSES are GREATLY APPRECIATED ! 😉
