I was firing intermittently the other day on my rear cylinder, header tubes on 9 cylinders were running at ~300f with the rear Dr. side running at 150f (12K miles, 2000 gts)
Then on Sunday it got to where it was obvious I lost the cylinder completely, that dead thumping sound in the exhaust.
What I've done is:
-Replaced spark plug
-Used HEI spark tester to make sure I ahve a good wire/coil, lot of spark
-took the valve cover off, rockers are in place and are torqued
-cranked engine, valves appear to be moving same amount as the rest so assume cam still has a lobe
-appears to be mechanically sound
Next to Fuel?....
-Doesn't viper fire half of injectors on one of two circuits? So injector should be getting a trigger signal to fire otherwise I would have lost other cyl's?
-Can I use a dvom to check for injector pulse? gotta figure out how connector comes off
-Has anyone had an injector fail at 12,000 miles?
-Any ideas on what next?
-I was going to pull injector and have it replaced under warranty, thoughts?
Kind of stuck here in the garage until I can get a v-10 back, thanks
