I bought car two months ago. Car turns on but only bank 1 is working. Bank 2 does not, have spark. I have checked fuel pump voltage pressure and relays I checked cam sensor replaced new. Checked cam sensors four replaced new. Checked ignition coils eight replaced new. I replaced all this sensors cause voltmeter was reading bad I thought this might be the problem realized I had a bad voltmeter. I got a Matco Max ME scanner and checked for codes no codes. So while researching I found a site. That said to check wiring issues. So I did got a voltmeter and checked wires all are good I checked the IVM that supplies power to the coils and injectors and all is good. I checked the DME. But found out that I do not have pulse on cylinders five to eight, I have twelve volts on every thing. Just no spark. On those four coils. I guess my question would be; can I assume my DME to be bad or what else can I check for not having spark on four coils?
