Having problems with your 2007 Chevrolet TrailBlazer SS ?
My neighbor has a 2007 Trailblazer SS. It will crank but no start.
Checked fuel pressure good at 58 no bleed down.Replaced ignition box, same problem. Hooked it up to a Snap-on scanner tested check engine light, it will turn on and off we can also activate relays with it so we think the PCM is good. With the scanner hooked up we cycle the ignition and we get an RPM reading upon cranking but no start so we think the crank sensor is good because of RPM reading.Have not checked the cam sensor yet
I have the same exact issue. Did you ever fix? If so, what was it?
