Fel pressure regulator is bad, I'm sure. When you Turn off the car, pressure remains in the injector rail. The diaphram in the regulator allows that pressure to enter the engine through the vacuum line that controls it, and floods the engine. I am 99.9% sure this is your problem

SOURCE: 1998 Saturn Engine won't start, after multiple tries, it floods

to unflood your engine you can just leave it alone overnight or take out the spark plugs and dry them off yourself but be sure to label your wires. if it is fuel injected you dont need to push the gas pedal to start it. as far as it not starting it could be its either not getting a spark or not getting any fuel you can check for a spark with a spark tester found at auto parts stores and to check for fuel they have a tester for that as well which if faulty will lead to fuel filter and or pump replacement if no spark then it could be the coil or plugs

SOURCE: '98 SL2 Saturn Traction Control

Traction control helps limit tire slip in acceleration on slippery surfaces. In the past you had to feather the gas pedal to prevent the drive wheels from spinning wildly on slippery pavement. Many of today's vehicles employ electronic controls to limit power delivery for the driver, eliminating wheel slip and helping the driver accelerate under control. Don't turn it off.

SOURCE: 98 Saturn SL2 - Stalling issues

DTC P1635

The 5 volt reference circuit provides a signal voltage to the linear EGR, MAP sensor, and TP sensor. The return line is grounded through the PCM. DTC P1635 detects a short to ground in any of the 3, 5 volt reference circuits or inside the PCM.

Conditions for Setting the DTC

The 5 volt reference is monitored whenever the ignition is ON.

DTC P1635 will set if the 5 volt reference signal is below 3.5 volts or above 5.5 volts. This voltage is monitored internally by the PCM.

Diagnostic Aids
If DTCs P0563, P0108, P1106, P0452, P0453, P1122, or P0122 are set, a short to B+ on the 5 volt reference circuit is probable. If the short exists while attempting to diagnose, PDT communications will be lost and driveability conditions will exist.

Driving car just shutoff want start again

Check to see if it is flooded, When you attempt to start the car put your foot on the accelerator and put it to the floor, keep it to the floor whilst trying to start the car yet dont pump the accelerator just keep it flat to the floor.

If it turns over the starter motor is fine,

Fuel Filter and pump is fine,

You got a spark so the electrics will be fine,

Just need to limit the problem down to whats happening under the head.

2002 Saturn SL2 was working fine an hour previous to the 'lock out'. I went to run another errand and it wouldn't start. Battery good, all lights, etc coming on. Wouldn't turn over. Anti-theft feature...

Your owners manual will tell you that the anti-theft can be turned off, but doesn't tell you how (dealer only?). If it is turning over but wont start, (trying to hit and outside temp is below 32) check the coolant temp sensor. Saturns notorious for cracked sensor sending false info to computer thus flooding engine.

Have you tried replacing the O2 sensor and having your fuel injectors cleaned and checked? It sounds like it could be a fuel problem / emissionsproblem.

97 Saturn sl2. Won't start after it gets warm. If you drive it for 15-20 minutes and try to restart it will not engage the starter. Wait a couple hours and it will start fine

It is your engine coolant temp sensor (ECTS). 99.9%. the saturn made them with a plastic tip, so they crack over time. A replacement should be about 15 bucks and not too hard to replace. You'll notice your engine temp gauge not working (always cold).

I don't know much about cars, but here's what happens. When your car is cold, the fuel runs rich. Your broken sensor is always reading that the engine is cold, but when it is warm, it runs too rich and floods your engine, not allowing it to start. When your engine is actually cold, everything is fine.

1999 Saturn SL1 trouble starting when warm

It was the coolant temperature sensor. It was telling the car that the coolant was always cold, therefore when starting a warm engine it was being flooded. $$$

Sounds like you have a bad motor mount, how to check is open the hood and push the car back while watching to see if the motor moves, if it does, then you have bad motor mounts.....
