So I started to work on my car 1973 1.7 2nd owner car. (white) it was sitting for 2 years cleaned the grounds, check the fusees check the oil, went to start, can't hear the gas pump did not turn over so I have power at the fuse and relays what's next ?

check for power at the pump.

Still injected? Check the relay board and the fuel pump relay.

Is the engine cranknig over fine? Just no fuel pump?

Rick it seems to cranck ok but not as fast as my red car as it was when it was running.

So it looks like the fuel pump. You can either do the troubleshooting with a meter or you can try the usual suspects. The fastest test and the most likely culprit is to replace the main power and fuel pump relays. They are the same relay as your headlights. If your headlights pop up ok take the relays from them and replace the two on the relay board.

what 2? my book show only 1? also does my computer needs to be grounded?

This is the relay lay-out.

Check the main power and fuel pump relays. Make sure they are getting power and they are working properly. You can cross the appropriate posts as well to test.

Fuel pump relay and the main power relay. The ECU is grounded through the wiring harness.
