It's probably something small that I missed, but here's what I got.
The car has been sitting since mid April. It has a full tank of gas and Sta-Bil in it.
Over this period of time, I've put on new spark plugs and wires, new headers, removed the air pump & associated lines, removed the EGR and cleaned up some other small vacuum lines.
I installed the headers and reducers and do NOT have a new 02 sensor in there yet, waiting on it to show up.
I wanted to start the car, but it'll just crank and I hear it pop like it's trying to fire, but never does. I reconfirmed firing order (HEI distributor) and it looks good.
Is there anything I missed or anything I removed that could be preventing it from starting?
Thanks for the help everyone!
