Hi again, I already asked about my car. I dont have fuel from the fuel pump, but the car start with no problem with starter fluid. I dont need to check the ADS relay (i m not sure about the name, but is the relay that manage fuel pump, spark, etc) because the engine runs. I check the fuel pump plug and there is no voltage. I have a wiring diagram a they say that fuse number 2 is for the fuel pump, so I check all the fuses in the fuse box and everything is ok. Could be another fuse in another place? I m pretty sure that is just a wiring problem, but I cant find the wiring diagram or the way to fix it. Thanks

Are you checking for voltage at the pump connector while someone is cranking the engine? There will be 0 volts there if the engine is not being cranked.

Hi willysp, Welcome to 2carpros and TY for the donation

Its time to check the dark green and black wire for an open circuit between the fuel pump connector all the way to the ASD relay dark green and black wire and also check for power at the red wire-let me know

After rereading the previous replies, it seems the likely problem is the pump itself. You can double-check by running a wire from the battery positive cable to the pump. The wire should connect to the terminal corresponding to the dark green wire with the black stripe. The terminal for the black wire must be grounded to a good clean ground spot on the body.
