87 Died after switching Tanks
 

Driving home last night, I noticed my right tank was low and switched over to the LEFT.

As soon as I did this the motor stopped, pulled over and put switch back to RIGHT tank and it started and ran fine.

Went to a servo and filled up and got home ok.

My truck is a 1987 350 TBI Auto stepside.

Is there a easy point to start at and find out why it does not run at all on the LEFT tank.

Tried again today and when on RIGHT tank it turns over and starts as normal, on LEFT tank it just turns and turns but will not fire

Do you hear the pump on the dead side?

Sounds like its the left fuel pump. In 87 with TBI, each tank had an electric fuel pump. sounds like the crossover is working also. Have someone listen for the left tank pump as you give it power. Also, see if there is a fuse for each fuel pump, that could be it too.

Yea its probably the pump. I would put a switch in anyway. You can still buy them from AC delco.

Still need to get someone to listen to the pump for me.

Yes the gauge swaps over
