SOURCE: spark plugs on 2002 Saturn vue
just completed a plug removal and install on my '02 awd v6. if you have the time and patience it's straight forward; common sense was most helpful. to gain access to the plugs, both fore and aft, you must remove, in short, everything near to, associated with, the air intake system. common tools plus a 1/4 socket, with 8 inch extension to hold a #10 star bit. these star bolts are under the rectangular plastic plate atop the intake. once you have those out, disconnect all the wiring, carefully. lift the intake out, look for plug covers, fore and aft, ignition assembly lays atop each row of three plugs. with the hands of a surgeon, remove the ignition assembly, and by golly ye shall see your reward. easy from then on.
replaced my plugs with the iridium 'honeys'; marked improvement in starting, acceleration, smoothnes, noise, and gas mileage to the value of + 3.0%. changed out the oil with mobile1 extended performance, changed transmission fluid. took a shower. time involved, 7.0 hrs. dealer be damned,,priceless!

SOURCE: 2002 Saturn Vue won't start
Non-start situations basically boil down to two things: No Fuel, or no spark.
I you are looking to throw a part at it, start with the crank sensor. They are cheap and not too hard to replace.
A full diagnostic approach would be to determine if it was a fuel or a spark problem. Check fuel pressures with a fuel pressure test guage: Low fuel pressure indicates a bad fuel pump or a bad fuel presssure regulator. Lastly on the fuel side, check t see if the injectors are getting a signal to fire, usually done with something called a noid light, I believe.
Spark diagnosis begins with first determining the condition, then finding the cause. Bad coil, loose wires, even the crank sensor are all suspect. A good repair manual with a flow chart is probably the best procedure to follow.
In my case, my manual only had a passing reference to the crank sensor and no diagnostic procedure to test it or even lead me to it. I found the solution through extensive web searches. Once I replaced it, all was well.

Yup. The throttle body connectors have a history of failing on these cars. Replace the throttle body and the wire connectors that go to it, and you're back in business. Not terribly difficult and you can get the parts from any dealer. Saturn actually has a bulletin out on this problem but they won't cover it unless you're under warranty - no recall for this.

I think you bought the dreaded Opel v6 in your Saturn. If it has six rubber hoses on the intake tubes, thats the Opel. A couple of years later, Saturn started using Honda v6's. A royal pain to replace the plugs, suggest a repair shop because the intake has to come off.

Under the intake manifold, it will need to be removed. Not too hard to do for the average diy but recommend buying a repair manual as a guide. you will need a 1/4" drive T30 torx socket with a long extension one of the bolts is hidden but the others are under the black cover on the top of the intake. you will also need to remove the coil pack held on with torx bolts. 8 or 10 inverted torx socket needed for that.
