I checked the spark, the fuel pump at the gas tank and I heard it click on for a few seconds. I pulled the valve cover and the timing chain seemed to have the correct amount of slack. What else should I check?

Re: 99` saturn won`t start.
You have spark and fuel pump primes when u turn the key / the timing chain has proper deflect but did it slip .sounds like the timing is off it may have spark but if timing has gone out it wont start either make sure it's in time next..

How long since a tune-up? Check applicable trouble codes? What led you to the fuel pump as being your problem?
Usually if it cranks good but won't start, have a helper crank it, while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
Only crank the starter motor for a few seconds at a time, let it cool off, a little.
I do realize, sometimes visually checking for spark, can be a pain. Also, checking fuel pressure can be a pain if no Schrader valve, but, not impossible.
I'm not saying the pump can't be your problem, it could be, just check the other issues, also. The fuel pump is in the gas tank.
best thing to do is check for fuel and spark.your vechicle type has fuel filter in gas tank.remove fuel pump by removing rear seat cushion by pulling the seat stopprr near the floor and lift the cushion up.remove the pump inspection cover on the right side of the vechicle.then remove pump harness connector and fuel lines then remove fuel pump with fuel filter.
If you haven't replaced the fuel filter in the last year or so, do it now-basic maintenance.
Check if the pump is working by turning key to ON (not crank), and listen for the pump in the tank to come on for a couple of seconds. Should hear a short hum or buzz verifying tank is working. If you don't hear it come on, either the pump is bad, or power is not reaching it. May have to pull the pump connector off at tank, and check for 12 volts on pump wire when someone cranks the car. If power there, the pump must be bad. If no power there at pump, check fuses for pump and fuel pump relay.
Without knowing if there are more things happening, noises, clicks, whirr sounds, or even how hard you drive it...
It typically sounds like a bad or clogged fuel filter... Although I've had some cars do this in the past, once they were heated up and had to wait an hour ow two to start again... that generally meant the fuel pump needed to be replaced.
This is called a Vapor Lock... and try as you might, they will not start
So, before you start going through quite a few external sensors, idle air control motors and egr valves and etc, etc at 85 dollars a pop...
Considering changing the FUEL filter and pour a bottle of gas drier in your fuel tank. You could have some condensation in your fuel and it may be as simple as that.
However if this dont help or the problem starts happening again, I would replace the fuel pump.
Check for gas and spark. To check gas, turn on the key and listen for a wirring sound coming from the fuel tank for a few seconds indicating pressure is building up. To check spark, pull off a plug wire and place the end near the engine. Turning over the engine should produce a spark.
Hello , If you run a fuel injected vehical out of fuel , then you may need to purge the system of air. Locate the schrader vale( looks like a bicycle tire valve ) on your fuel rail. Remove the plastic cap by un-threading it. Push the center of the valve down , watch your face and eyes! Wipe up any fuel , the cycle the key on and off a few times and make sure you hear the fuel pump. Re-press down the schrader valve and check for pressure. It should really shoot out not dribble. Make sure the car has fuel , cycle the key again( cycle means on off on off not turning to start) car should start if there is no air in lines. Thank you , Quinn
what needs to be checked is spark and fuel. spark is easy, pull a plug and see if it arcs while cranking. if that doesnt happen i would start at the plug and work backwards.
as far as fuel goes first i would check to see if the pump turns on when turning the key in the on position (not cranking) and listen for a humming. if that is heard i would move to the fuel rail and check for fuel pressure by pressing in the valve on the driver side of fuel rail (usually covered by a cap, looks like a large tire valve)
Your fuel pump is in the gas tank, You should be able to hear it begin to pump with the key in the on posiiton (not start) You should hear it pump for 5 seconds. Also replacing the fuel filter is a good idea as well. The valve you are talking about should be tested with fuel pressure tester. It should be about 75psi.
