Well to start with the truck had issues with Misfiring and Backfiring through the Carburetor, Replaced the Distributor Cap & Rotor, Ignition Control Module, Spark Plugs & Wires and set the Distributor Timing to specs at 4 degrees BTDC and test drove and the vehicle drove really good for the most part but was still Backfiring through the Carburetor Occassionally at 3/4 Throttle! Do you have any idea what could be causing the problem? Also have a Hard starting concern (Cold or Hot), I noticed the Fuel Injector wires were melted and touching and I replaced the wiring to the Injectors and retested and still a hard start! Fuel won't start spraying through the Injectors until about 30 seconds to One Minute of crank time and the Injectors will start spraying and the truck will start! So I was thinking that it could possibly be a defective Fuel Injector/ECM Module or whatever controls it! Or it could possibly be a Fuel Pump concern. What do u think it is or could be causing the problems I'm having? Any ideas, diagnosing or repairs to fix this problem?
have the same problem?
