Hey everyone. I'm having a problem with my 03 cavalier. I have no power to my fuel pump, instrument cluster, ob2 connector. When I turn the key the radio works, ac, hazards, and wipers. It cranks but just won't start. I've replaced the pump, ignition switch, cluster, and looked at all the fuses. Please help.

Im guessing if theres no gas pumping then its not getting fuel to run. Try looking for cracks in the distributor, spark plug wires or even vac lines. As far as the cluster goes it may just be a bad one. Theres mechanical and electric clusters, maybe got the wrong one? Not sure if connectors are diff but i know they are for diff gens. I had no power to my horn, data port or interior lights and ended up being the fuse. This was a 99 however. Cant help with the fuel pump. Could just be u have 3 issues on ur hands. When and what might help others diagnose better. Good luck
