Wont start spark plugs are good oil was just changed it worked yesturday went to start it up and nothing nothing was left on over nite what could it b?

It may have knocked the wires off the sensor behind the front harmonic balancer,check.

the engine (there are more than one engine)
has a distributor.
"have spark at coil down to dizzy but no spark at plugs"
this can mean only 2 things.
1: spark wires are dead. all 4, kinda hard to believe huh?
2: the dizzy is way off time. so time the dizzy and now spark
lands on each wire term.
if not a dizzy engine, post exact version of engine and country.

Changing the plugs probably had nothing to do with it.
White smoke is usually a sign the engine is burning coolant or trans fluid. You might want to check those fluid levels.
If the coolant is low, you may have a leaking head gasket or intake gasket.

-Not the spark plug that you just replaced.
-It could be bad crank, Cam., broken timing belt, bad ignition module or blown fuses.
-Check it out.

Good luck

Make sure battery has a full charge. Have a helper crank it, while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse.

most likely suspect is the carb

However, I'd start with your basic tune-up first...

• replace spark plugs
• replace spark plug wires
• replace Dist cap and rotor
• replace fuel filter
• replace air filter
• change oil
  
• adjust timing and base idle speed
• adjust fuel mixture (if available)

Cheers

could be distributor. remove cap and rotor and slotted wheel. look for brown dust covering optical sensor from bad bearing. If yes, replace distributor. It triggers spark and fuel injection.

Did you change the spark plugs one wire at a time or did you pull all the wires off an then changed the plugs? If you put the spark plug wires back on wrong this will cause some of the problems you are facing. Get a $20 manual from you parts store and it will give you the diagram and steps to put the wires on correctly. good luck and get some help from a neighbor who understands car repair.

Needs Crank sensor, that's why you have no spark,this sensor controls reference for spark to plugs. Good
luck

did you overheat the vehicle?..if oil is on one plug severely you may have mechanical issue (rings/valve stems) leaking into cylinder...get diagnostic compression test and leak down and scope electrical secondary system and advise me results
