Engine Mechanical problem
1999 Chevy Astro 6 cyl Two Wheel Drive Automatic 175000 miles
----------------------------------------------------------------
my fuel pump was whining really loud and quit and the van stop running going down the road. my check guages and check engine light came on and the van will not start all the relay are good and the fuel pump is good. the motor was replace about 2 months. the fuel pump does not come on at all but its ok. Im not shure what it is, im think electrical but dont know where to start looking

Are you saying the pump won't even prime, when you turn on the key, no crank?

If your saying you have good spark at the plugs, during cranking and it's just a fuel pump issue, start at the fuel pump relay. One of those terminals at the relay, should be hot all the time, D1 terminal. If it isn't hot, go to the ecm B fuse, not only check the fuse,but, check that one of the fuse terminals is hot.

My information shows D1 and C3 terminals at the relay connector are for the switch side of the relay. You might doublecheck by looking at the diagram on the relay. If D1 is hot and you use a jumper to C3 from D1 at the socket, by the way you probably should use an inline fuse on the jumper, just in case, the pump should run like crazy, if it doesn't, there something wrong with the voltage circuit--- ground circuit or the pump.

It could be the computer isn't energizing the relay for some reason, but, even without the proper rotational signals, the pump should still prime at key on. That's how I see it.
