1988 Oldsmobile Ciera car died suddenly and wont start back

To determine if its fuel or spark problem do below and comeback with some results this is where we start the diagnosis

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

Hello

If I understand you correctly, the car died just sitting there idling. When you say you tried to start it, the starter was turning over but it wasn't starting? Or you turned the key on, the dash light came on but nothing happens?

I am going with it was turning over (correct me if I am wrong) - you noticed the white smoke out of the intake.

Have you been loosing any anti-freeze? How much is in there now?

If the engine is turning over, then remove the oil filler cap. You need to be able to see inside the valve covers to see the lifters. Have someone try and start the car - the belts should be spinning... While they are spinning look inside the valve cover and see if the lifters are moving up and down.

If you are able to pull codes that would be great. You could go to Auto Zone or O'Reilly's and for free they can pull the codes to the car. Most important. Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for free also they can bring their tester out and check your battery, alternator and starter.

If not - let me know what you find out with the above. Also, please be specific on your car... There are several to choose from. Is your just a Ciera, or is it a Ciera Cruiser? It is a V6 but is it a 2.8L or 3.8L... Please be specific here.

Thanks and let me know

Are you sure you are getting spark to the plugs?

Can you remove a plug wire and have someone start it and have something in the plug end near something metal and see if the spark jumps from the plug wire to the metal.

Did you have a chance to check in the valve cover when cranking?

Hello

Here is the info on the Crank Sensor

Disconnect battery ground cable, then remove sensor 3-way connector.
Raise and support vehicle.
Rotate harmonic balancer so slot in disc is aligned with sensor, Figs. 30 and 31.
Loosen sensor attaching bolt, then slide sensor outboard and remove through notch in sensor housing.
Reverse procedure to install. Adjust sensor so that an equal clearance exists on both sides of disc (approximately .030 inch), then tighten attaching bolt and re-check clearance. Readjust as necessary.
