My '95 S-10 Blazer (throttle body injection) won't start. It was
running fine last night and now it turns over fine and even runs for a
few seconds when I spray starting fluid. Visible spark.

I took off the fuel filter to check for pressure, and there's none,
even with the ignition on. Shouldn't it be pumping gas out onto the
ground?

I'd like to check the fuel pump fuse next. According to Haynes, you
have to drop the tank to get to the pump itself so I want to make sure
it's not just a fuse first. Does anybody know which fuse it is?

Another possibility is that I'm out of gas. The electronic dash blue
lights don't work, so I have no gas gauge. I put 2 gallons in, but
it's facing uphill in the driveway. Is it possible that there was so
little left in the tank that a slope makes that much difference (1/8
tank)? According to the odo I should still have about 2/3 of a tank
anyway.

I have gotten "one more start" out of a nearly dead GM fuel pump my giving
the tank a whack with a rubber hammer.

There should be a fuse in the underhood electrical box and a relay.

most GM's I've seen have the fuses clearly marked on the panel or the
underhood panel, on it's cover. If not the owners book will tell the
tale, but your probably dealing with the pump.

had a similar experience with an '89 suburban. the gauge read 1/2,
but was inop. put in 5 gallons then had to crank for awhile ( >30
seconds) then it started.

I hate to say it , but its about time for that pump to fail. I just did
mine last winter on my '95.
