Help!! I have a 2004 trailblazer tbz i6 I changed 3 coils and everything was fine a couple days later I changed all the spark plugs and the vvt silinoid and after I put everything back together the cluster illuminates with a check engine light a battery light abs light and brake light gages dont cycle radio dosnt turn on horn dosnt work or keyless entry can't roll up my windows wont crank at all not even a click fuel pump dose prime. Battery was charged and if I bypassed the ignition relay terminal thats suppoed to ground when the pcm tells it to it cranks. The battery went dead and I left it that way for a couple days ans went out and used jumper cables and another car to jump it it cranked with the key but didn't start due to me having low battery at the time then I cycled the key and it went back to doing nothing. The blower motor is about the only thing that works other then the dash clusters. It dose have 309xxx miles on it but I need it to last just a little longer I'm without a car at the moment please give me suggestions on what to replace or try!
