I have an 1989 buick that after it runs for a while and gets hot and i shut it off it wont start it just cranks.After it cools down it starts right up. I changed the ignition module and now it wont start at all its just cranking. Its like its not getting fuel but it is.

Cranks but no start condition-do below:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
