Question about Saturn L300

1 Answer

2002 saturn L300 jst died while parked just after I started it! It would not start at all & not sure why! If fuel pump quit would that cause it to not start? I checked pressure on fuel rail & gas came out for a sec but then nev did again after trying to start! Makes a weird buzzing noise by the opening to throttle body where some sensor or module is attatched to side of throttle body where air tube goes on! There is no po or anything! Very worried!

When you turn the key to start what happens ? Does the starter engage an spin the engine ? This would be a crank - no - start condition . Or when you turn the key nothing happens ! This is a no - crank - no start condition . If the engine does spin when turning the key to start and it doesn't start an run you need to see whats missing - spark , fuel or compression . Videos on youtube showing how to test . You need to hook up a fuel pressure gauge to check for fuel . Just pushing the valve on the fuel rail isn't good enough .

SOURCE: 1999 chevy blazer fuel problem

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

I'm sure you have installed a fuel pressure gauge and monitored the fuel pressure while the problem is occurring?Another diagnostic tool which is easy to do,is while the problem is occurring,unplug one sensor at a time beginning with the Mass Air Flow first,.if it uses one.Many times,not always,depending on the sensor,if the sensor is taken out of the picture as far as what the PCM is seeing,like unplugging the MAF,the PCM will substitute the missing sensor output with a generic value that will allow the engine to at least run,and if unplugging for example the MAF,the engine idle speed returns to normal,you know you're onto the problem.You didn't mention if the engine ran ok other than the idle problem.As far as checking for vacuum leaks,i use something like brake cleaner or WD 40,more of a liquid,and it does sound like a vacuum leak.Plastic intake manifolds do develop nearly invisible cracks that open up more with heat.Revsisit the possibility.And as for the PCM,it is possible,but more likely a mechanical problem.Lastly,remove an O2 sensor or two before the catalytic convertor,run the engine and see if anything changes.Cheap way to verify the catalytic convertor is flowing and not restricting engine airflow,as i have seen bad cats cause misfire codes and strange problems.Good luck.

SOURCE: I have a Saturn L200.

You should try re-learning the pass-lock system first. Turn the key to the on position and leave it on for 10 min, or until the security light goes out. Turn the key off for at least 30 sec. Turn the key back on, very important not to turn too far and bump the starter, for another 10 minute cycle. Do this 3 times for a total of 30 min. After the 3rd cycle it should start.

SOURCE: throttle body injectors not fiering but there is fuel pressure

the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up

There is no close to start ,something is missing spark or fuel pressure . If it died on the freeway the fuel pump quit working or something in the ignition system did . The engine spins when you turn the key to the start position ? Crank - no start No Start Diagnostic Basics EricTheCarGuy

Car stalls while driving. Will start after about five minutes. Is not flooded. Doesn't usually do this until after it has been driven a bit. Does it more in warm weather. Check engine light sometimes...


I'd have fuel pressure tested. I had a 95' did same thing. Cold winter day, worked fine, as soon as it got warmer, or hot out, it would quit, and re-start 20 minutes later and go for a distance then die again. If I parked in the shade on a hot day, I'd get further before it quit for the first time. I started carrying a fuel pressure gauge with me. Cool in the morning my fuel pressure was up to spec @ 49-50psi. Once it got warm/hot out and it died, Hooked up gauge and it was at 2-5psi. Let it sit and cool off 20-30 minutes, pressure would jump back up and run good until fuel pump got hot again and then pressure dropped off and car quit. It sure sounds like the fuel pump, but the hard part will be getting the car to the shop at the right time, or they will need to let it run on the lot until it quits to confirm the pressure drop. One thing you can try is when car quits, have a can of WD-40 or quick start with you and a screwdriver. Loosen the clamp on the air intake hose where it connects to the front of the throttle body and pull it off. With vehicle off, turn throttle linkage so the plate opens up enough to spray WD-40 a second or 2 in the throttle body. Then try to start it. If it starts and runs momentarily, then you can be pretty sure it's fuel related and my guess is the pump needs replacement.

Saturn 2003 L300 quits running and takes about 30 minutes to restart


Start with the simple by replacing your fuel filter, but most likely it's going to be your fuel pump that will need to be replaced soon. It's common for the fuel pump on the Saturn's to go weak after a few years, the piston and the cylinder sleeves after a few years wear and the clearance is much grater when the pump heats up.
The extra clearance will cause the fuel pressure to drop just enough to keep the fuel injectors from working. Once the pump has cooled down enough for the piston and cylinder sleeves to create enough fuel pressure, your engine can run again.
You may get luck as mentioned to start with the simple and replace your fuel filter first, then the fuel pump if that did not help.
Thank you for using fixya and good luck

i know this is an old post but im having the same problem,the crank position sensor wasn't the problem or the fuel pump,i replaced the cps with a new one and problem never quit and im putting out 48psi on fuel pressure,these are common problems but before replacing them check into it further

2002 Saturn SC1 - Starts fine and runs well until the engine gets warm. Then I will step on the gas peddle and the engine will die. Sometimes it won't die it will just have no power to move. Fuel Pump?...


Most Likely Coolant temp sensor & connector.Located in cyclinder head under upper radiatior hose.Two wires to connector yellow & black.Replacement sensor is brass (from saturn) Original is ceramic & cracks cause poor performance,stalling,idle issues.Also check plugs & wires for carbon tracking.Replace plugs & wires as a set all at once.Hope this helps
