We'll this is my first post and I really hope its in the correct spot. Over the past 2 years I have been building my 53 GMC. I have put it on a 2000 Sonoma frame and am using a crate 5.0l gm TBI engine out of a 92 GMC. I have used the factory harness with the ECM # 1227747. I have it wired but cannot get the throttle body solinoids to allow the gas to feed the engine. I have been stumped for weeks and have been constantly reading to try and get this figured out. Any help would be greatly appreciated.
