1998 Pathfinder difficulty starting

[Deadpath]

In the last few days it is becoming much harder to start. It usually takes a few cranks to get going and sometimes dies right away after it does start.

Some additional info:
I am about 3/4 of a tank through a bottle of Techron fuel system cleaner.

No engine codes.

The battery is pretty new and cranks just fine.

Once started it runs great and runs fine at hiway speeds so I am thinking it is not the fuel filter.

The spark plug cables look a bit old, have not looked at the plugs yet.

Any help is appreciated.

Thanks

Ensure both ends of the battery terminals are secured well and are free of corrosion.

No issues there but I just noticed that if I park facing downhill on my driveway there are popping noises coming from my exhaust and little to no power. Once I rolled to flat ground it ran fine and I drove it 45 miles with no problems. The exhaust looks rusty throughout the entire unit.


Looks like an entire new exhaust system in my future....
