Have a 97 merc 5.7 with delco ignition system. Ran for a while fine then sputtered and stalled. Now no start. Weak spark, no injector pulse. Good fuel pressure. New coil. Any ideas?
Have you checked for water in the fuel filter?
Does the fuel pump run for 2 seconds when you turn the key to the run position?
Pressure checked the fuel pump?
Do you have spark?
