have a 1992 gmc safari van. engine cranks but will not "hit" to start. appears to not be getting fuel.
tank if full and running yesterday.
was told to turn key on and listen for fuel pump to turn on. heard no sound
possible no electric to fuel pump. bad fuse? bad fuel relay? or just a bad
fuel pump?

8th digit in the vin# W or a Z? tells me if it is cpi or tbi.

you do have a fuel pump relay that should have your two second prime when you first turn your key to the run position. Uses the ECM B fuse. From your fuel pump relay you should have a gray and an orange wire. those are the wires the power up the pump. by putting a heat bulb between those two wires you can check to see it you have power and ground going back to the pump. you could still have a wiring problem back by the tank but it will give you a clue by telling you that the relay and ecm are working to get the fuel pump going.

have someone turn the key while you bang on the bottom of the fuel tank. many times jarring the tanl will get the fuel pump going again. If it starts, plan on getting a new fuel pump because it is going out.

vin code W means that your engine should be a CPI. fuel pressure should be 54 to 64 psi.
