I have a 1990 Toyota pickup that is an off road project truck that sits for long periods of time. It ran fine when I parked it six months ago and just recently I had to swap the air flow meter because I was not getting any power at the fuel pump. After I swaped the air meter then I was recieving power at the fuel pump and the truck was running. A week later I went to go move the truck and it does not have power at the fuel pump again. So this is the second air flow meter that I have gone through. Any ideas on why this is happening? THX

Check the circuit opening relay -the airflow meter grounds the Fc terminal of the COR from there powers goes to the fuel pump.
