The fuel pump relay is under the hood in the MAXI fuse box, it is a black box with a huge wiring bundle comming out of it.

Use lots of wd40 on tank strap bolts. If they bigin to bind tighten them up and losen again to get rust out of threads. If you remove the straps, why not remove the fill neck and lower tank? Much easier to work that way!!!

the relay and fuse are in the power distribution box under the hood. as far a by pass you still can use an aftermarket electric pump ,however the cost will be about the same as re3moving the old pump in the tank if that is the cause in the first place. if all you need is the relay replaced then i'm sure that the pump is still good. if the pump is bad then make sure if you by pass the in tank pump that the new under hood electric pump has enough pressure to give the needed gpm(gallons per minute) required for your system and that if wired into the current fuel circuit that you dissconnect the wire harness to your tank pump

4.3 and 2.8 motors have a ceramic module in the distributor. if you have alot of miles on the truck, and there is no spark, that module is usually the culprit. easy to replace with a nut driver and some dielectric grease. mod is located in the distributor when you take the cap off look straight dowm and its right there.
also check eec relay and fuse. that will also cause the prob.
In a 97 lumina sedan, you have to drop the fuel tank. this is tricky in that the wiring harness and fuel lines have to be disconnected before removal. the lines can be tough because the fuel filter has a compression fitting on one end and a quick disconnect fitting on the other end. The compression fitting may be rusted solid and you can't use a torch on it. ok.. the how to. First try to empty the tank. second, using jack stands and blocking the front wheels, get the car up as high as you possibly can. Disconnect the fuel filler tube from the tank. loosen (do not yet remove) the tank straps and get some room to see the top of the tank. carefully disconnect the wiring harness from the pump/sensor unit. disconnect the fuel pressure and return lines. check your clearances and make sure you have it all disconnected. carefully position a floor jack under the tank. support the tank gently. remove the tank straps, drop the tank and bring it out you will see the pump assy and a ring that has tangs on it on the top of the tank. using a hammer and (preferrably) a brass drift push the ring to the left (counter clockwise) and as it loosens just unscrew it and pull out the pump. remember that the pump and the sending unit are an assembly. treat it gently if you plan on saving it! while you're there, be sure to replace that fuel filter!!! put it back in the way you got it out good luck! Please rate my answer so I get points for it.
