Cranks good but not starting 200 1991

Hi,

Do you have spark from the coil wire?
Pull that wire from the distributor and lay it next to a strut tower stud but not touching it. About 1/4 " away is usually good.
Crank the engine and you should see a white & red to bluish spark jump to the stud.

If no spark suspect the Crank Position Sensor (CPS) to be bad. This is located behind the engine head. Check for a frayed cable or corroded connector.
You have to have spark after that.

You should have heard the fuel pumps stop running right after you stop cranking the engine around.
When you first turn the key on they will run for a moment. This is from the ECU only. Not the following relay as they are separate.
If you are not hearing them then this leads to the System relay being bad. It is located under the glove box on the back wall. It controls running the pumps and turning on the injectors for fuel to cylinders.

If you hear the pumps and have spark it still may not run if one half of the relay is not working or the injectors are not getting grounded by the ECU for some reason or another.
This is getting you down to the far end of the troubleshooting trail.
At this point you need to spray starting fluid into the intake vacuum ports.
If it sputters to run and stops then it's a fuel supply issue to the injectors or they are not opening.

From here you need to post back for more information.
I will hope you will tell us, in bold letters of the subject line, "FOUND IT!"

Both the CPS and that relay are the number one "no start" candidates.
