Question about 1993 Saturn SL2

1 Answer

Electrical problem I have a Satun EFI/OHC '94, my car start very well when is cool, then I can drive for about 20mins and shutdown himself, no start again. I leave it cool for 1 hr and start again. It looks like something is heated and cut the current to the spark plugs. I already changed the spark plugs and the cables, the fuel pressure is ok. Please let me know if somebody can help me or tell me where can I find free the electrical blue prints. Regards.

Sounds like a coil or oxygen sensor! you should scan the code if engine light is on but if i were you i would start with the following! usually if the oxygen sensor is gone they get hot it will shut the car down when cooled it will do it again usually when stopped most likely coil could be stopped or in your travel? hope this helps get coil treated before changing it!!!if desired

I have a 1996 saturn 1.9 litre. Ohc. I replased water pump and still getting very warm. I found a pin hole in the underside of the radiator cap. Its on the bottom on the part above the water hole. Could...

bars treatment is for a temporary fix and like everything temporary it will fail when you want it most. Holes in the cooling system no matter how small will stop the pressure build up that raises the boiling point of water . Water under pressure takes in more heat so the engine runs cooler That is why you have a pressure rated radiator cap. I would recommend a compression test to check for head gasket problem. Have a flow test done on the radiator to check for blocked cores. make sure that there is not an air lock in the cooling system

Pressure test the radiator for leaks if it holds pressure start the engine. And check if pressure rises and keeps rising ,if it does it points to blown gasket or cracked head. A faulty thermostat can make it over heat so check it out . I would not mix the anti freeze as a lot of them don't mix well. put the anti freeze in all year as it stops corrosion of the cooling system.

Use anit-freeze anti-boil additive in the radiator at the correct percentage as it stops bubbles forming on the hot bits of the engine and allows for more efficient cooling of the block and head and stops the block freezing when the ambient temperature drops too low.. It also stops corrosion in the coolant parts. Some additives will not mix with bars or others so be careful when adding anything to the system.

95 toyota t100 starts when cool then shuts down after running about an hour. Won't restart for 2-3 hours. Runs well until shutdown. 3.4l V6.

Possibly the fuel/mixture sensor thinking that the engine is cold and needs more fuel causing the engine to flood?

94 camry has power but will not start

Try tapping and wiggling the EFI main relay. Camrys this age will sometimes develop broken contacts in the EFI main relay base, the socket it sits in. When contact is lost, the engine just dies, as no power is getting to the ECU. You will know if this is so because the check engine light does not glow when you first turn on the ignition.

Car suddenly loosin power

It sounds like your ignition source is going out. Typically when coils get older they begin to stop working when they get warmer. You drive the car, it warms up the old coil, you start getting less and less power. The car sits a while, the coil cools, and it begins to work for a while longer.

Fuse am2 problem on 94 toyota 2.2 4 cyl. blow out when trying to start car

The electrical circuit from the AM 2 fuse goes to the ignition switch, it leaves the switch out and branches off to the clutch start switch at the clutch pedal and then to the starter relay. The black and white wire coming out of the relay goes to the starter solenoid.

The circuit also includes the engine main relay, cooling fan relay, injection relay, EFI relay, and so on. You should have a wiring schematic to do this. If you don't have a repair manual with the schematics, you can get one with a subscription to the
