Injectors not firing

[sam_bo3]

I have been working on my project for awhile (got the engine in August). It did run once for about 5 minutes. Came back the next day and it would try to fire but not quite get started (didn't worry because had to use loads of starter fliud the first time.) 2 days later it wouldn't fire at all. I am thinking about scapping out the engine and trans to swap in a 327 chevy. I saw one on ebay and the chevy fit nicely. The small displacement shouldn't create too much low end torque for the rear end too handle would it? I plan on fabbing up a cage and reinforcing the frame for safety's sake. I don't plan on making much over 300hp. But american horses tend to feel a little bigger than japanesse.BTW The wiring is fine to the injectors. The ecu isn't grouding them. Any idea what sensor could be loosing connection or failing?
