How did you determine that the fuel pump is not working? Did you run an actual fuel pump test or pressure test? Can you give me some history on the vehicle leading up to the problem of not starting?
It died on a interstate just hesistated a little and cut off.When I towed it home I ran a obd2 scan on it and it had no codes.I sprayed throttle body cleaner in the throttle body and it ran a little and cut back off when the cleaner dried up.So its not getting fuel.
The vehicle has about 90,000 miles on it.I have a test light but do not know which prong to test.The check engine light is on when the key is on.It does have a p0171 bank one systen to lean but it is pending.
There should also be a 15 amp EFI2 fuse next to the two headlights fuses. The 20 amp fuse is the main power supply to the circuit opening relay which controls the fuel pump. If you're 100% certain that the 20 amp fuse has power on both sides with the key in the on position and you do not have power to the black wire with a red line that the fuel pump this means is the circuit opening relay is not functioning or the computer is not energizing or turning on the circuit opening relay. Circuit opening relay is located on the back side of the junction block on the driver side instrument panel. This is where the other fuse box is located. If you reach your hand up onto the back side of this fuse box there is one large gray single wire probably 8 gauge and next to that are three relays that are exactly the same the first relay closest the passenger side of the circuit opening relay does a click when you turn the key to the start position? As a test you could swap that relay with the one next to it and see if the car starts or it clicks in the start position. Your other option to rule out whether not you also are dealing with the fuel pump problem is to run a jumper wire with 12 V directly to the black wire with a red tracer. You would need to tap into this wire with the connector plug-in otherwise you will also have removed the ground or use a jumper box and just use power on the black wire with a red line and ground on the white wire with a black line pins in the fuel pump bracket.
