Buick Century: 1993 Buick Century 3.3 L stopped running on

Customer Question

1993 Buick Century 3.3 L stopped running on owner. Hauled to my shop. It tries to start, but with no success. I uplugged MAP sensor tried to start, but wouldn't. I checked resistance on coil packs. All read o.k. Replaced ICM, same symptons. Was going to check resistance & voltage next on crank sensor. Also found dry rotted rubber hose on fuel regulator & replaced - still no start. Fuel pump is working, sprayed starter fluid in intake, just acts like firing, really tries to start but won't. I also scanned with my OBD 1, no codes at all. Any other advice here?

If you remove the plug wires from one of the coils and crank the engine, do you get good spark from the coil while cranking?
