1999 chev Blazer 4.3 litre automatic will not start, I have Fuel (presssure 60 psi) and Fire. This vehicle has recently had new Plugs wires and Cap to solve a rough idle Problem. This took care of the problem for awhile but the vehicle began acting poorly the other day and I had a rough time getting home. The blazer would not go the next day. I dertemined I had no spark and traced the problem to the Crank sensor. I replaced the crank sensor and my spark returned But still it will not start. I have fuel pressure for sure. The vehicle is equiped with a remote started, I have this disconnected for now. The Fuel injectors are working, I checked them with a noid Light. Does anyone have any ideas where I should check next ?????
