If it's a stick shift, try push starting the car, it may be a bad ignition switch not working in the start position and working in the on position, related to the fuel pump circuit.

SOURCE: 95 saturn won't start when hot

Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.

SOURCE: gas not getting to engine

sounds like your fuel pump, normally fuel pumps die gradually not just like that, so best check fule pump fuses first, also i can not remeber if these have a fuel cut off switch, this is normally located arround the fire wall it looks like a red or black rubber button, if you have one you can press that and see if that sorts it, if not then it more than likley is the fuel pump and will possibly need replacing, but check the other things first, better a new fuse than a new pump...hope that helps a bit

Check fuel pressure. Bad pumps will work, just not enough pressure. If the engine light is on, check codes. Your's has a fuel pressure sensor and module that could go bad.

2006 tahoe is parked on step incline backed in and now wont start

Back to basics, as things fail while just sitting still sometimes. Getting spark to plugs? Correct fuel pressure? Will small spray of starter fluid make it start for a few seconds?

05 Altima cranks but wont start, new cam and crank sensor, new battery, fuel line is ok???

If the car sat, would bet all the money in my pockets that it's bad gas. Adding fresh gas won't solve the problem. You need to add a fuel stabilizer ( purchased for under $10 at Autozone) that you just add directly to the tank.
It could also be the case that the coil wires are dry and cracked from sitting, cause sparks to ground out.

Whenever your car won't start it is always one of three things-- fuel, spark or air. I hear you saying fuel is coming in, but to be sure you could try spraying a quick spray of carb cleaner or better yet starter fluid into the air intake and see if it briefly starts. If it does, then shuts down immediately, it's a fuel issue.

If not, then it is likely spark (air is usually not restricted but you may as well check the air filter and throttle body and make sure they aren't clogged. )

Check the spark in each cylinder. The problem could be a bad coil or fouled plugs.

If fuel, air and spark all check out, then the problem could be timing but this is highly unlikely.

I have a 2005 Maxima and my BF ran it out of gas and sine then my car starts but wont stay unningeven after adding fuel. We have changed the MAF sensor also all 6 spark plugs. It still doesnt want to

Change the fuel filter then see if it will start.If it doesn't the you will need to check the fuel pressure if its not within the specs (CHILTON AUTO MANUAL) then replace the fuel pump.

2001 GMC Safari does not start unless starting fluid is added to once it starts I must apply my foot on the gas peddle it boggles down a little then will stay on once I release the gas pedal the van stalls...

Better have the fuel pressure checked for starters. Even though the pump comes on, your fuel pressure might be too low. Lots of GM vehicles are finicky about proper fuel pressure, especially at start up. It could be a weak pump or failed fuel pressure regulator-a pressure test will sort it all out.

How can i diagnose whether my cts or tbs or pcm is bad on my 2000 saturn sl2

Fuel pump testing should be done before assuming anything . An disconnecting O2 sensor is not going to do anything . Is there a security light lit on the instrument cluster ? Anti- theft system problem . Your best bet would be to have it towed to a qualified repair shop instead of guessing what's wrong a just replacing parts .

I own that same car

If you never moved it in ten months,
you will have to take all 4 brakes apart
and clean off all rust and lube pad slippers etc

The (P) is the Electronic Parking Brake
Is wouldn't worry about that until I cleaned
up the brakes and screwed the rear caliper
piston in and out a few times and ratcheted
up the park brake.

When you say started,you mean what?
Ready to drive again?

You Flushed the Brake Fluid? That gets done every 2 years
The Coolant (GO 5 Yellow) every 3 years?
Trans Fluid and Power Steering,every 30,000 miles
not over 3 years?
Clean MAF Sensor
Change Front 2, O2 Sensors at 100,000 miles
Spark Plugs every 70,000 miles?
Check Fuel Pressure at rail --- 42#

I ran out of gas in my 99 chevy tahoe. will not start after gas was pumped. changed fuel filter and additional ignition parts & sensors. More likely the fuel pump or fuel injectors?

If you add a few tablespoons of gas directly to the throttle body after removing the air filter, or use starting fluid (ether), then if the car starts and runs after cranking, then it is a bad fuel pump.

Check the fuel pressure of the fuel pump rail to verify if gas is coming through the system.

If not, it's definitely a fuel pump.

If it were an injector, then it would still try to start on some cylinders assuming it's getting spark.

The fact that the problem started after gas was pumped, points to a fuel pump, as well.

So, I would go for the fuel pump if the fuel pressure is 0 psi or near that, or if one discovers that there isn't any gas coming through the piping when cranking.

Also, check fuses for the fuel pump and injectors.

Car will not start

you getting sparks; check the basic from fuse and relay. Its seems like you not getting any fuel by having to give it fuel, check the fuel pump see if it working, you can remove it and connect straight to 12v and do a jump. If the fuel pump is good then it will be the crank sensor, crank sensor turn on the fuel pump as long the engine continue turning over. what crank sensor does it sense the crank/flywheel turning and it send single to the computer than computer send power to the fuel pump. sensor tend to go bad over time and heat exposure; the sensor it fairly cheap to replace.
