MY TRUCK WILL TURN OVER, BUT WON'T START. IT WILL CRANK AND RUN WITH ETHER, BUT CHOKES DOWN AS SOON AS IT BURNS OFF. IT HAS CODES P1406, P1153, AND PO 153 SLOW BANK #2 AND PO 153 SLOW BANK #1. A GUY AT THE PARTS STORE HAD ME CHANGE #1 O2 SENSOR, HOWEVER I AM STILL NOT GETTING FUEL. I FEEL FUEL PUMP ,BUT WHERE DO I GO FROM HERE?

If you think it is a fuel issue, Use a fuel pressure gage to double check pressure. I'm not sure of litre size of engine? There should be a prime connector for the pump, underhood, driverside fender lining, close to firewall, red wire with electrical connector, nothing pugged into it. If you use a jumper wire run B+ from battery to connector, the pump should run. You don't have to use the key. Use an inline fuse on the jumper. If the pump won't run, check for good B+ and ground at the pump, if that checks out and no pump action, sounds like the pump.

The 1406 is an egr code, could cause problems.
