I have intake backfire and issues starting, the backfire

Customer Question

I have intake backfire and issues starting
JA: Where exactly do you think the noise is coming from? And how long has this been going on?
Customer: the backfire comes from where the air filter would be hooked up (took it off to inspect what was going on) and it has gotten worse since I unplugged the battery to fix my AC compressor.
JA: What is the make/model/year of your car?
Customer: 1997 Jeep Wrangler Sahara 4.0 6 cylinder
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: yes and what I have done so far... I have replaced all the fuel injectors and did a full tune up on the engine
JA: Anything else you think the mechanic should know?
Customer: when I start my car it will almost never start the first time... Always the second time
