I have replaced Mass-air-flow & fuel pump but the issue still exist. Car won't start..., I beleive the "Reduced Power" gage light is my clue to solving this issue..., I know what is not the issue but need to find the real cause why my engine won't crank..., don't tell me it's the fuel pump cause even my mechanic admitted the new fuel pump didn't provide the necessary "FIX" . . . , the Dealer wants too much to inspect my car and I'm currently unemployed & can't afford their price...., PLEASE share with me if you have ever had this issue with the "Reduced Power" gage light on your Saturn. Thanks!
I'll just put some things out there , loose or wiring poblems in starter circuit,ignition switch , starter faulty,battery ?? if auto trans nutral safety ,if standard netural safety on clutch pedal.?
just trying to help good luck hope something works.

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 [email protected] Please give me a fixya rating if this information is helpful to you

Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, or won't start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too
SOURCE: reduced power light came on
reduced power messge is not caused by oil pressure. i assume this a 3.0L v6. this engine has a electronic throttle body which is a electric motor that operates the throttle plate that takes the place of a throttle cable. in cold weather the pcv (positive crankcase venelation) system accumulates moisture that will form on the throttle plate, in cold weather the water freezes and causes throttle plate to stick. when the ecm detects any malfunction whithin the throttle control circuit it is put in to reduced power mode that limits throttle position. usually resets after ign. is cycled. there is a service bullitin to re-position pcv hose behind throttle plate to reduce moisture bulid-up on throttle plate. your saturn dealer can perform this service.
SOURCE: reduced power for real!!!!
I had the same thing happen to me yesterday. Sitting at a light, went to accellerate and would barely move. The same lights came on for me too. I had it towed to the Saturn dealership and they tell me it's the computer control for the transmission. It's going to cost me in excess of $950.00 to replace. I did a little research and apparently this is an ogoing problem with 2003 Vues.
