Question
It will not start by cranking engine unless starting fluid is sprayed in breather. Checked, it is getting fuel from the fuel pump.

Answer
HI TOM, GREAT NAME BY THE WAY...THIS DOES NOT MAKE SENSE. IF IT STARTS WITH STARTER FLUID AND IS GETTING FUEL FROM THE PUMP AND WONT START ???? HOW ARE YOU CHECKING FOR FUEL, AT THE SHRADER VALVE BY THE INTAKE. YOU MAY THINK THERE IS FUEL BECAUSE WHEN YOU PUSH DOWN ON THE SHRADER VALVE, FUEL COMES OUT,BUT DOES IT KEEP COMING OUT ALL THE WHILE YOU ARE CRANKING THE ENGINE ?? THIS IS IMPORTANT. TRY THIS AND SEE!!! YOU MAY JUST HAVE RESIDUAL PRESSURE[THERE FOR 2 OR 3 SECONDS AND THEN NOTHING.. WOULD LIKE IT IF YOU HAD A FUEL PRESS GAUGE TO CK THIS. I THINK YOU WILL FIND THAT PRESSURE IS VERY WEAK OR NOT THERE AT ALL. LET ME KNOW IF YOU CAN CK THE ABOVE AND GET BACK TO ME IF YOU NEED MORE INFO..BY THE WAY WE HAVE REPLACED MANY FUEL PUMPS ON THESE VANS. PUMP IS BAD OR THE WIRING ON TOP OF SENDING UNIT GETS BAD.
