My 05 aviator tries to start but won't. A fuel computer data error shows on dash and I can't hear the fuel pump. I've already checked fuses, relays, and fuel reset switch. What else needs checked?

SOURCE: will not start, no dash gauges light except "low gas level"

I have a '99 dodge dakota, 4 cyl, 5 speed manual. While researching a no start problem ran across possible solution to this problem. If no guage lights show when key truned to on position then normally a bad ignition switch. With fully charged battery and working ignition switch guage lights should slight up then go out when ignition in "on" position. Try shaking the key back and forth.

SOURCE: Fuel Pump Relay Switch

Underneath your hood, behind the passenger side headlight, behind the core support, is a bank of 2-8 relays. One of those relays is the relay needed for your fuel pump. There will also be a fuel pump relay fuse located there. The relay designation should be on the cover of the relay compartment.

Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.

Check fuses first, but could be needs new CPU

Testimonial: "Thanks for your help, we checked the fuses even swapped out the relays. The CPU was a thought but someone else tried it and it didn't work. Might still try it though. Is there any other symptoms that would indicate the CPU is bad? We changed out the ignition switch, 135.00, changed the CPS, 42.00. I hear the CPU is about 150.00. When we run the tester it comes back with no error codes."
