This started as a sputtering/popping at 3lbs of boost. Drove about 45 miles just fine, hitting 8-10lbs of boost a few times, then all of a sudden at 3lbs it would sputter. Drove another 20 miles or so back on home just fine, just not getting into boost.
Immediately thought coil or ign mod, they tested ok with a Caspers tester, but I swapped both out...same issue...then trying another test, it started then died immediately...now it won't start at all.
Fuel Pressure is around 40 lbs after pump priming when key turned on.
Got out the spark tester, not getting any spark.
Cam sensor is tight, plugged in the cam sensor setting tool...cranked motor, its blinking so cam signal good.
Next probed the cam sensor wire at the ignition module...its getting a signal.
Then probed the crank sensor signal wire at the ign mod, blue wire, 10th wire from firewall, its getting the signal fine.
Swapped out the ECM tonight, no change.....
Stumped....what else could I look for???
Thanks
