You could have a problem with a vacuum line.
Does it have spark, fuel, compression?
Check engine compression Check engine timing
it could me bad fuel ..or fuel pump
If the engine is not giving spark or sending any fuel to the cylinders. Then I would seriously suggest checking out the CKP or crank position sensor located on the front of the engine.
The engine might not be getting any fuel. The engine may also have weak or no fire at the spark plugs. Check these two places to find the problem.
Check the timing for the 90 Corsica. the most likely cause for the engine not starting is it has jumped time causing the engine to fire at the wrong time.
Okay, crank it. No start...are you getting fuel? If so, check for spark. If you are getting spark and fuel, check to see if your timing is correct. After that, I'm really not sure...if you are getting gas and spark, then the thing should fire up.
you need three things for an engine to run. proper air/fuel mixture, compression and spark at the proper time.
The engine needs fuel, compression and spark to run. You are missing one of those.
engine cranks but wont start means one of these things.. Air, Fuel, Spark, or compression
carb. adjustment, fuel filter or the engine is shot.
First check for fire at any of the sparkplugs and if you have spark then check your fuel pressure and if its not within specs then replace the pump.
