Engine died while driving. Scanner shows following codes: 556 & 543
Relay is tested and works (putting your finger on it while turning on ignition). The spool has about 80 Ohms.
Pump ain't working.
556: fuel pump relay primary circuit failure
543: fuel pump secondary failure battery to control Module.
Is that a cabling issue?
Where do I find the fuel pump fuse? and that stupid dead man switch?
Any help is highly appric..., abbrec..., aprec..., thanks in advance.
