Electrical Problem??? Help Needed!!!
Going nuts trying to figure out what went wrong... The engine has been running perfect. All of the sudden a few days ago The engine started to cut out as I was driving. It would cut out for just a second and then be fine after that. I didn't think much of it at the time. The car was fine the rest of the day. Then the next day I took the car out to test a new front stabilizer bar. The engine started normal and ran fine for the first few minutes then started to cut out again, worse this time. The car would start to cut out and stall, then it would come back to life. Luckily I was close to home because this time the condition did not go away. I figured maybe I have a loose conection or maybe a bad batch of gas.
Over the next two days I have been pulling what's left of my hair out trying to determine the problem. Here is what I have checked so far. Starting from the basics: The car is getting plenty of fuel and a generous spark. I checked the timing and that is dead on. I checked the compression, that is perfect as well. I got a fresh gallon of gas and ran off of that to see if it was bad fuel. Thinking that possibly the coil was going bad, I replaced it along with a new resistor.
The engine cranks fine and attempts to start and sometimes will run for a few seconds, but will shut right down. It definetly seems to me that I have some type of electrical issue. (maybe the ignition switch?)
What could cause a perfectly running engine to all of the sudden cease to function out of the blue. Especially when all the basics seem to be in place. Air, Fuel, Ignition...
Sounds simple right?
Any Ideas?
My setup is simple, nothing special: Stock 1973, 302 ford. Mallory Dual Point distibutor. Blaster 2 coil. Edelbrock aluminum intake and Edelbrock 1406, 600cfm carb.
