There are a number of possible reasons your 85 Chevy Celebrity has no spark.
A few possibilities include:
Defective Distributor Cap
Defective Rotor
Failed ignition module
Failed coil
Failed reluctor
Worn out distributor
Bad spark plug wires
Defective engine control module (computer)
Wiring problems including broken wires or connectors unpluged also dirty or fouled connections
are you getting spark?
You are missing fuel or spark.
I would replace the ignetion module that is in the distributor.
For an engine to start it needs spark to the plugs and fuel. Without both it will not start.
do you mean it cranks, but will not start?
Two common reasons why an engine will crank over, but not start: There is no spark. There is no gasoline.
An engine which cranks but will not start is not receiving enough fuel or has no spark. A clogged fuel filter or bad spark plugs often cause this problem.
It takes 3 things for the engine to run. Fuel, spark, & air. You have air, and the truck turns over so you are missing either spark or fuel. You have to find out which of those you are missing.
Cranks is the motor turning over, But cranks and won't start means either you no fuel or no spark or both.
If it cranks, first confirm spark present
crank sensor
Look for spark and fuel 1st then comeback
