1992 SC. Fuel pump replaced, worked for about 200 miles. Failed again, pump replaced again and failed. Fuses viewed as blown (fuel pump) and Ignition (MAXI). Replaced, no go. Oil Sending Unit replaced, all fuses verified as OK. Still no power being delivered to pump. Seems to be an obvious short somewhere. Any ideas?
You need to get the schematic / wiring diagram . There is a junction block in the center console where the wiring is routed to the entire car. The contact on the power wire to the pump gets burned /dirty and becomes intermittant . It needs to be cleaned .This happened to me twice.

Pulling plug wirs is a big mistake unless you know what your doing and you don't sound like you do. It sound like a frost plug is corroded away. You should be able to start your engine even if it had no coolant at al. the coolant only cools the engine ,it does not stop it from running.Now you need a wiring diagram for your engine to see if you have the wires in the right place.......otherwise the engine will not start ever.Worse case ....it could be a head gasket and if that is the case give it to someone whom wants a free car to work on themselves...............Ken
If you have tried starting fluid to verify there is no spark (use sparingly), a likely culprit is the crank sensor. The ignition module could also be at fault. If there is zero pressure at the fuel rail, the pump has failed. If pressure is low, the pump may be failing or the filter may be clogged. Check fuses and relays before investing in a new pump, sensor, or ignition module. If you have to guess and check, replace the fuel filter first, as it should be replaced periodically anyway, esp. if you end up replacing the fuel pump. It is also possible that a wiring harness has corroded or been broken if there is really no fuel at all and no spark at all.
the fuel pump has most likely failed, that is really all that goes wrong with the fuel pump system, if it has over 100,000 miles u can almost certainly suspect the pump, replace it.

Wow... if the whole car is doing that i would guess it to be electrical issues.like a bad ground...basically a major cable that connects to your frame or directly to the negative side of the battery. You see, electricity leaves its source makes a device operate then the electricity goes back to the source. kinda like a big circle... when you start your car...the battery gets you going...then...the Alternator takes over...recharges the battery while making your car operate on an electrical standpoint. if you break that circle...lights out...be it the wires losing contact. battery failure( usually they STAY dead) or it could be an alternator with an intermittent problem. Based on a money stand point...your battery is fine...i'd replace the alternator...not trusting it after all that. (100- 300 bucks) if it STILL does it..then have a mechanic replace your wiring harness associated with the ignition, starter,alternator and battery( should be just one bundle of wires to fit that portion) .200 to 400 bucks to get that replaced. i hope this helps you out with finding out what the problem is...and i'm sorry to say...getting a fuel filter and fuel pump replacement would not cause a radio to lose power...the battery is like a back up system. don't go back to that mechanic ever again..as he is ripping you off. im an electrician so i know about electricity and i also tinker with cars quite a bit for fun.
The Saturn Fuel pump relay and fuse is located undar the panes on the passenger side of the center console near the passengers left foot there are two relays there that look identical one is fuel pump relay. Just switch them around they are bot the same and see if the fuel pump runs now also the fuel pump fuse is in there i can't send diaagrams on fixya because their program will not let them go through if you need one email me at firstname.lastname@example.org Please give me a fixya rating if this information is helpful to you
