Did you buy new pumps yet?

I ordered a new complete pump setup with sending unit, it should arrive today.


After doing more research on the VATS system it looks like that would result in a no-crank condition but I can get mine to turn over, just won't supply power to the fuel pump relay.


Does anyone know if there is a fuel pump shutoff on this car? I'm wondering if it's possible that this is tripped, telling the computer to not energize the relay.


Finally, I would hate to go this route, but if all the wiring, relay, pumps are verified good but the output is not turning on from the ECU does anyone know how I can test the ECU itself to make sure it's functional?


Thanks for everyone's help!
