Start with your battery.
Take the terminals off and have it tested.
If it is low on charge, have it charged first.
Make sure the lead posts are clean and "shiny bright".
Then got to the terminals.
Make sure they are clean and "shiny bright".
Now check the wires, be certain they are not corroded inside the plastic covers.
If all that is "spiffy", have the solenoid and the starter tested.
God bless your efforts.

DTC P0732 sets when 2nd clutch still slips after the PCM has commanded high main line pressure
DTC P0734 sets when 4th clutch still slips after the PCM has commanded high main line pressure.
DTC P0733 sets when 3rd clutch still slips after the PCM has commanded high main line pressure.
The powertrain control module (PCM) uses the crankshaft position (CKP) sensor, input speed sensor (ISS) and output speed sensor (OSS) to determine engine speed, input shaft speed and output shaft speed. These sensor readings are used to determine the current gear ratio and RPM slip across the torque converter. The PCM uses this information from the sensors to determine if the commanded gear matches the actual gear. During normal driving conditions, the PCM will adapt main line pressure via the pressure control (PC) solenoid to prevent slipping and harsh shifts. Shift solenoid 2 is used to apply or release second gear clutch. The PCM controls 2nd gear by controlling the ground for shift solenoid 2. The PCM will turn the solenoid Off (open the driver circuit) when second gear is commanded On to apply 2nd clutch. Shift solenoid 2 is supplied ignition voltage from the fuel pump relay whenever the PCM commands the fuel pump relay On.
Do you know how to test main line pressure ? Also , with the valve body off air check clutch packs . Do you know how to do that ? How many miles on the trany ?

p0410 is an emission problem, Check the fuse for the air pump. Listen to see if it comes on when the engine is started, colder start. Make sure that the vacuum lines is still on, both ends. Common Problems That Trigger the P0410 Code.
  • Defective Air Pump Check Valve(s)
  • Faulty Air Pump or Air Pump Relay
  • Faulty air control solenoids or vacuum lines
  • System may be restricted or plugged with carbon.

The dealer is right a faulty crankshaft position sensor indeed causes the exact symptoms you have, replace that 1st.

There could be a few reasons for that happening....It is most likely a FEUL problem. Is it feul injection or carburettor?? If it is a carburretor, then there could be dirt in the jets. You could also have an inline filter that is blocked & not enough feul is getting through to the carb. Another thing that could be causing the car not to start after being running awhile is if the feul line is too close to the engine and is getting too much heat, causing the feul to "bubble" and faporise in the line, untill it cools down. Another cause could be that the float level in the carb is set too low or you have a faulty needle & seat.

Hope this helps.

You will have to drop the fuel tank down far enough to access the top of the fuel tank. You will probably have to remove the exhaust system and all hoses and electrical connections. Disconnect the connector from the sensor, pry it out of the top of the fuel pump module. Be careful not to break the top of the fuel pump module. When installing the n

Have the battery checked,and the battery connections checked to make sure they are not corroded,then check neutral safety switch,and starter.

Correct. The one upstream, closest to the engine.

I believe those are electric pick up from the drive shaft or the rear end...Look for the wires that may have come loose/disconnected..good luck.

You Mean the fuel pressure regulator Or fuel tank pressure sensor?? There is a fuel tank pressure sensor on top of fuel tank 98+.

It is an air intake silencer. It quiets down the motor when you are throttling up.

noise is caused by lack of oil to lifters, or worn timeing chain. if noise is from lifters it should go away wit proper oil level, if still there needs timeing chain.

if you have high resistance in secondary ign. system (plug wires, ign.coil) this will cause this code to set. make sure you are using a high quality spark plug wire set. not from autozone!!! and denso non platinum tipped spark plugs. also use a diaelectric grease on plug wires to keep moisture out.

if you are refering to a inertia switch like on a ford that kills the fuel pump in a crash, the saturn does not have one
