Question about 1999 Saturn SL
1999 saturn ,
driving along when dash goes haywire, speedometer and tachometer jumping around ,at same time fuel pump relay is freaking out clicking on and off.this started off as an intermittent problem and got to the point of undrivability. when car will not run there is no fuel relay power and no spark.took it to cut rate as i used the save symptoms mode with the cruise control switch. it popped module,crank position sensor ,temp sensor,fuel relay,all at the same time. the car will not pop a code normally .you must use this option to get any information.To me it sounds like a physical short .but we have been unable to duplicate symptoms while going over all physical wiring.we have gone over it time and time agian.at this point we think it might be the brain...ANY SUGGESTIONS?
I think I know what is wrong.....
Tale off the fuse box cover under the hood, and look for the heavy wire on the side closest to the steering wheel, with a bolt/nut on the end connecting it to the fuse box assembly. AFTER DISCONNECTING the battery, take off the bolt and remove the wire. There should be a flat washer about one-inch across on the end of the wire. Thoroughly clean off any corrosion on the bottom of this washer with heavy sandpaper, and also clean off the plate the washer makes contact with on the fuse box assembly. Clean off any sand, replace the washer and and tighten the bolt firmly. Reconnect the battery.
Corrosion on this washer/plate causes a poor electrical connection which shuts off power to everything, sometimes for a fraction of a second, sometimes for longer. It can vary based on temperature and humidity, and gets worse once it starts.
