hello, new member, my scenario is that i have an 01 blazer, fuel pump is fairly new, pcv clean, checked fuses, fuel filter new, i did indeed changed the plug wires a few days ago, the vechile ran perfectly but this morning decided not to, theirs a spark going from the coil to the distributor but from there on to the plugs their is nothing. any suggestions or ideas would be deeply appreciated.

 

I would suggest you have the Ignition Control Module (ICM) tested. Many auto parts stores can do this. On my 98 it's attached to the same bracket that holds the coil.
