I changed plugs,pulled the car out of the garage and it died would not fire back up.I did not here the fuel pump come on so with 180 plus miles I changed the fuel pump.Still won't start so I checked if I have fire at the plugs all good so I changed out one relay mr400709 and nothing.There are three more relays mr538851 should I change all of them or is there something else that I am over looking,plus since I had the battery unpluged it shows no code? I am lost if no help here I will have it taken to a mech shop.Thanks.
