I have a 2003 4x4 blazer 4.3l with a crank no start, no spark or fule condition I was driving it just died. troubleshooting I replaced

• ignition control module
• Ignition coil
• Distributor cap and rotor
• Ignition switch in the steering column
• The brain I think its called the (ecm)
• Crank and cam sensor
• Fule pump

I'm thinking there was some sort of surge in electricity because I checked the cam, crank sensor and the ignition coil with a multimeter and they all were shot, but after more troubleshooting and messing around with stuff I checked the old coil and the new I got a good reading from the old coil and nothing from the new. I get more frustrated and confused everytime I start trying to wrap my mind around what the problem could be


if anyone has any tips or suggestions or if your dealing with a similar problem I'd appreciate the help I also have a diagnostic tool also but I haven't gotten to pulling the codes

Please and thank you for your help

I also want to reiterate to examine that I see M connector because the white and black wire runs right next to the black and white ground wire so make sure there’s no damage there as a source of this partial short before we start cutting wires
