I have a 94 camaro that I bought for my daughter and last week while she was driving it quit.I towed it in to my garage and pulled the balancer off and -found a small piece of a razor blade blocking the crank sensor magnetic pickup the ignition fuse was also blown so I change both. It still would not start.so we took off the ignition control module and 3 coils and went and tested it at auto zone and they both tested ok. So I bought the cam position sensor and the other crank sensor that is on the side off the block and new plugs . I went home and installed the two sensors and new plugs and it still wont run it will try to start and die if you give it gas while cranking the motor cranking slows down and somtimes it kicks back.I tested the fuel pressure and had 42 lbs. on the rail and checked the spark on all 6 plugs and they all fire. I checked one with it out and with my thumb in the spark plug hole while cranking and the spark was in time with compression.I installed a new fuel pressure regulator and installed a new computer from auto zone and had it flashed .It started barely and run like crap while holding the gas down it was flooding and misfiring and had no power and died again and will not start .We used the old knock module and put it in the new computer.Could this cause all the problem I know it retards the timing from the knock sensor or can the Ignition control module and coils be bad even though they tested good. If any one has had trouble like this let me know .I will pull the timing chain and gear and check it even though it seemed to compress with the spark it acts like its about 40 degrees out of time.I have been working on cars for years but this one is tough. The motor is the 3.4 V6 and has the OBD1.5 DIAGNOSTIC on it it will not flash any codes I am thinking about using a lap top and buying a ALDL cable and downloading software to try and see if it gives a code.

for all the time you invested in the car and the $$$ sounds like you could of gotten a good running and esier to fix LT1..
I heard the V6's were just a PITA to work on when problems start. Its the old 3.4 liter right?
did you check the MAF? or any intake problems?
I wish I could help really but don't know anything about the V6's. Good luck and welcome to the site
Check you catalytic converter, your problem sounds just like the one my father had with a 91 w/ 3.1L. It drove him nuts for months, he replaced a lot of the same components you mentioned .Then he finally checked the cat, and he noticed that the "honeycomb" fell and was blocking the exhaust. Just a suggestion.
