Hey guys, I have been working on my LT1 swap into the '71 for quite some time now and finally I tried to fire it up but is cranks and will not start. I am suspicious of the computer and the harness as the guy who modified it, Jeff Roberts, was far from the best. Horrible customer service. I have 42 pounds of fuel pressure at the rail but there is no spark and there is no signal at the injector harness plugs. The optispark, coil and ICM are all new. The engine was rebuilt also. I am out of ideas, please help.
