The ing switch is the first place I look. Then the wiring.......
Make sure the wiring connector on the s'colume is not damaged.

Ok so I thought my problem was fixed but its not. Turns out I am not get fuel to carb I guess. I just pour a few drops directly into the carb and it started right up. Then it ran fine until I turned it off. What would you all recommend to do first. I just replaced the fuel filter and lines from the electric fuel pump to the carb.

Does your FP, pump?
Could you have pinched a line?
Hope your ele FP is near the gas tank as ele FP's are 'pushers' and not 'suckers like the OEM mech. FP is.

When I unplug the fuel line into the fuel filter fuel leaks out. I would guess that means my fuel pump is good??? Or would that always be the case??

Crank the eng with the line off, and it should SQUIRT, big time.

Does your fuel filter have a return line to the tank?

When I bought mine in march my return line off the fuel filter was plugged. I, with the honest intention of fixing all the PO screw ups, was gonna fix that and put back in my return line. So I did. My car wouldn't start. Long story short, I had to plug that line back to make it run. I replaced my fuel pump because I wasn't getting fuel to the carb, I replaced my rubber fuel lines on both sides of the vehicle and I replaced my fuel filter. None of those helped until I plugged the return line back.

A) if you are gonna keep that return line make sure that line is on top of the line going to the carb or you cause vapor lock

B) if you are like me and your 600cfm Edelbrock is too thirsty, you might consider plugging up that return line

So I pulled the fuel line off the carb and put it in a water bottle. Turn the electric fuel pump on and fuel pumps into the bottle. I went back to the spark plugs and checked 4 (this was the first thing I changed out all 6 brand new). The 4 had a light orange small spark, definitely not blue. They were also already black. Could this possible be the problem.

I have not tried to plug the fuel return yet. I am rookie at this and trying to learn as much as possible. So that was going to be my last step.

Autolite Double Platinum Spark Plug
Just replaced them too. Right after it would not start, that was the first thing I did. What should I check/replace next?
