Did you properly align the cam sensor stalk when you installed the cam sensor drive? Balancer is keyed to the crank so it can't move. The sensor vane is bolted to the back of the balancer. This fixes ignition timing so there isn't much to check with a timing light.

did you set the gap for the crank sensor properly? Too far away and you could get issues with misfires.

Grounds: If you paint your block you must be careful to leave a bare spot for the grounds. Most paint will insulate any ground wires leading to possible unexpected issues related to poor quality grounds.

The cam sensor stalk must be installed in a very specific orientation. To check if your issue is a cam sensor or it's alignment you can disconnect the sensor. The motor may take several tries to start, but when it starts it should run as well as ever. This thread has good tips on getting the sensor oriented properly. note the crankshaft position is critical. Incorrect positioning of the stalk can lead to issues with engine operation. http://www.sccoa.com/forums/showthread.php?t=83849&highlight=stab+sensor

If you find you need to fix wiring, or re-align the cam sensor, swap out the plugs as well. More than likely from your attempts to start they are now fuel fouled and will make diagnosis difficult.

p.s. Since you have the BHJ, it is likely you don't have a mark on the balancer for 26degrees After Top Dead Center. You'll need to make one as it the motor must be at 26 ATDC for you to align the cam sensor stalk. This web page shows how to install the BHJ along with how to get your 26ADTC marks. http://www.tccoa.com/articles/mn12how-to/BHJ/BHJ-install.html

ok, have spark and obviously getting fuel as i can smell it strongly at the exaughst. Still will not start.. acts like timing issue still... Not sure what to do other that put the motor back in the crate it came in and tell them we are too stupid to start it!!! Any ideas? Thanks in advance and yes I have searched the threads...

Is the firing order correct? Many manuals for our cars has it listed incorrectly.
