thanks i am working on learning the d.m.m. i can measure ohms and volts. my meter does not measure current draw i just found out. from my electrician friend. o yes continuety also. so i am just a little hesitant because i just learned these things in the last two weeks. i have made notes right on the sperry d.m.m. i did spray some carb cleaner around the injector seals at the manifold but not the top of the injectors, or the manifold itself. i read about using i believe propane but that makes me nervous. i will try the manifold tomorrow.
