Default Yet another fuel problem

hello guys please help with this; my car was slowly overheating not matter the speed and decided to change the thermostat only to find that it did not have one installed, after I ended installing the thermostat I tried to start the car and I got no fuel, I did not touch nothing electrical afaik, I have no fuel pressure on the fuel rail and I can't hear the fuel pump priming (like I could before) when I opened the switch to the run position; I disconnected the connector at the drivers side wheel well to test for voltage on the connector and cleaned the ground beside it.
I tried several times to get it to work, checked the fuses under the hood and switched relays with the horn relay to test.
I got 12 V directly to the fuel pump and it does work, I have it replaced like 6 months ago, I tested with a test light (small) if I got voltage at the connector under the wheel well when I open the switch and the illuminate for about 2 seconds and then shuts off but I can't get the fuel pump to prime.
I tested with this probe:

I hope you can help me guys!
Thanks

Did you try jumping terminals 30 and 87 at the relay socket ??...you need to test all 4 terminals on the relay socket also with a 12 volt test light...do you know how to do it ??
