Someone Help Me Please?!!

Hi, I have a 99 olds alero 2.4 with about 150,000 miles on it. It wont start! I tried everything I could think of. I replaced the fuel filter, spark plugs, ignition coil, air filter, and even had a mechanic check my o2 sensors and cat! I even tried spraying starter fluid in the throttle body! and still it wont start! the only time it starts is if I unplug the electrical connector from the fuel pump and open the gas cap n still it only runs really rough for 2secs and shuts off. then wont start again! any ideas?!

The three basic for today's nternal combustion engines- fuel, spark, and air

So do a fuel pressure check- beg or borrow the gage-

do a spark test- again find a spark tester- then that splits the analysis in half-- any other advice is guessing- and you might as well flip a coin without testing- as to what to fix...

Hi Cally412,

As someone stated already it's a guess thing without the gauges and
such but, a trick i was told by a reputable mechanic has come in handy
for me and perhaps you may benefit from it.... RE: FUEL PRESSURE

If you can get it started??? and it will at least run a few minutes???
then you can try this.

Start car
let it run a few minutes
turn car off
pull the vaccum line off of the pressure regulator
look for any gasoline in the line

If there is gasoline in that line then the fuel pressure
regulator is NO GOOD!

NOTE: In case you don't know where the F.P.R. is located
it's at the end of the fuel rail towards the end of the
engine that has the serpentine belt and is 2 inches or
so around and should have an ''L'' shaped rubber
connector that is on the end of like a 1/4 inch plastic
tube (line)


Problem with this method is your car has to run at least
for a short time. So if nothing else you can keep it in mind
for future reference.:disappoin

It just sounds like a fuel pressure problem. I found out a
long time ago on my Alero that just because fuel gets from
the tank to the engine don't mean the pressure is okay!
For CERTAIN you don't want to hap-hazzardly just replace
parts unless you got LOTS-O-CASH to throw away. Example
being that little fuel pressure regulator (at least around here)
is like $95.00 argh!!! gulp!!!:runaround:

Luck to ya on yer project!:grinyes:
