My 1999 SC2 died on the way home from work a couple weeks ago, and I just
got around to replacing the fuel pump today (like everyone told me it was).
Well, it wasn't the pump. I still don't hear the pump run when I first turn
the key to 'on'. I switched the contactor with the one for the HVAC
(they're both the same model number) and still no juice. Does anyone have
an idea for me? My wife needs her car back, so I need to get this fixed.
Thanks in advance,
Justin

Did you get the fuel filter as well?

Start over, what is it doing, give us symptoms. Does it give out hot or
cold? Does it start to stumble before it dies? Will it not start hot?

You need these 3 things for that engine to run, Air-Fuel-Spark. What of
those 3 is it not getting?

There is a fuel pump priming wire near the battery. For future reference
try it, you dont need to swap relays to prime the pump.
 
Ok, here it is from the beginning:
My car has 136000 miles on it and it has been perfect running from the day I
got it with just 32 miles on it. I'm on my way home one day and all of a
sudden the car dies for no apparent reason. I pull off the road and check
for obvious things and see nothing. I then try to start the car and it does
just fine and I complete my little journey home with no other problems.
The next morning on the way to work the car dies again (coincidentally at
almost the exact same place as the day before) but this time it will NOT
start back up and has not since.
I checked the car for spark, and there is definitely spark. The air filter
is fine, practically brand new. I have not replaced the fuel filter,, but
it wasn't my first point of attack since the fuel pump wasn't running. I
checked the fuel lines for pressure and there was none. Everyone I spoke
with said "that's easy, it's your fuel pump". Sooo....... I get a fuel
pump and replaced it the other day. I was all excited when I put gas back
in the tank and turned the engine over, and over, and over.... you get
the idea.
Where do I go from here? Any and all ideas are much appreciated.

So are you or are you not currently getting fuel pressure? If not there
"should" be (not sure with saturn) a red wire not hooked to anything
near the battery. You can jumper that to the positive post and that
should supply power straight to your fuel pump. You can even try
spraying some starting fluid into the intake to see if you get the motor
to hit that way. Just dont spray to much.
 
I am not getting fuel pressure. I don't see a red wire that I could hook up
to the battery, so Saturn must not have done that. I checked the fuse, and
the contactor, and still no luck. Anything else? I plan on working on this
in the morniing. Thanks!
 
Well I wish my copy of GM eSI covered Saturns... You could really use a
schematic for this. You're probably not getting power to your fuel pump.
You will need to start tracing down why that is. You can always go back
to the pigtail coming from your fuel tank and hook a 12v source directly
up to the fuel pump to see if it runs. (incase of fire be ready to get
the heck out from under there.)

Good luck.
 
I got it figured out. I opened the trunk this morning to hand-over-hand the
wires and I saw a 'lake' in the drivers side of the trunk. The seal on the
trunk is leaking allowing water to accumulate in the recessed area behind
the wheel well. I drained the water out and saw a badly corroded connector
that just happened to go to my fuel pump. I cut tthe wires and put in butt
splices in its place and the pump runs fine. Thanks for your help!

is there more then 1 fuel filter maybe? I have heard of more then 3 on
some cars. One at tank, inline, and one by the motor in some cars.
Just so you know.

There is a pickup screen at the pump, seldom ever gets clogged. Then the
fuel filter, then some small screens pressed into the injectors. Thats
all that I know of.
