Question about 1994 Saturn Sc
I have a 1994 saturn sc1 with a fuel pump that will not kick on. the 10amp fuse and relay are both in good working order. the pump is brand new. the ground distribution block was found to be under water. please help
Flood damaged cars are usually declared total losses, in part for the very problems you are having. Every electrical connection that is not a water-tight seal is subject to corrosion and failure..
I would pull that block off and remove everything from it. See if you could find a used box from salvage, or clean yours thoroughly. Every relay should be suspect until you know it is in good working order, or buy new relays. Use CRC electronic cleaner spray on all connections after scrubbing them clean. If there is any chance water got near the computer, pull its connectors off and check inside for corrosion. These connections are not weather type connections if the computer is inside the car.

It seems likely to be a wiring fault but don`t rule out faulty fuel pump!

Most Likely Coolant temp sensor & connector.Located in cyclinder head under upper radiatior hose.Two wires to connector yellow & black.Replacement sensor is brass (from saturn) Original is ceramic & cracks cause poor performance,stalling,idle issues.Also check plugs & wires for carbon tracking.Replace plugs & wires as a set all at once.Hope this helps

SOURCE: 94 saturn 1.9L flooding out
i bet the coolant temp sensor is bad,,,when the sensor cracks coolant leaks into and wrecks it and then the coolant leaks thru the sensor and into the harness,,,and this causes the car to dump too much fuel because the computer is seeing a temp that is not real and therefore the air fuel mixture is off and flooding the car,,,typical issue,replace the coolant temp sensor and then harness,,like $75 for both at saturn,,do not by the aftermarket ones,yes the cost less but they are junk and will not work either,,,also i bet if you put the gas pedal to the floor or pump it when this happens i bet the car starts and smokes when it does,,,,saturn redsigned the sensor for this reason,it was plastic and they made it brass so now it can not crack and leak,the aftermarket ones are still plastic junk

Hello! The fuel pump relay is located on the bottom right of the instrument panel junction block...the junction block is beneath the center of the instrument panel...
