2004 Sonata GLS 2.7 6cyl. Mfg. late 2003. Vin# KMHWF35H14A919865. Seems to have all electrical relays and components in different places than Forums and Manuals for like cars. Need to find location of ECM and Engine Control Relay. Have checked under hood, taken lower dash out on both sides, center radio and shifter console taken out. Nothing! Have wiring diagram that shows the car has them. Either it's not getting Ground to circuit of coil and relay, or bad relay, or I'm stumped. Also checked relay box behind interior fuse box. Not there or none bad. Have tested every relay I can find with no fails. Also new coil and Crank Position Sensor.
