1991 oldsmobile no fire Sign In

I have a 91 oldsmoble cutlass ceria that wont start, it is getting gas, and the starter is good however there is no fire going to the engine. it was running just fine maybe a little on the rough side but I turned it off for a second and when i went to start it, my thumb slipped off of the key and it did not complete the start and when i attempted to start it again it would not start. I pulled a plug to see if there was fire and nothing...i have had this happen before and i would disconnect the battery and wait a few minuets and it would start, now nothing i had the crankcase sensor replaced a few week ago...could someone help

I'm assuming you meant crank sensor.

It's best to test spark with a spark tester and fuel with a gauge and noid light. Once your sure it's spark, you want to make sure the crank sensor is sending a out a good signal and the Ign module is recieving it, that module had power and ground.

A quick check would be to see it the engine is showing an rpm reading while cranking, if not you may have got a bad sensor....

You also want to check all the fuses as well......
