Tech...this is not a hardcore question but I know the ones that can help are in this section. I have done the whole 1-ton build up with coilovers...ya know..the new average build. Well for my drivetrain...I went with a 5.7L Vortec out of a 97 truck and a built Turbo350 and Stak 3spd. My harness and ECM are from Howell. My problem now is....it wont start. As soon as I turn on the ignition..the check engine light starts flashing and never stops. I am getting fuel but no spark. I have triple checked everything and it is all correct according to Howell's instructions. Anybody ever has this issue. I really don't wanna call them tomorrow if it is something simple that my dumb ass is overlooking.
