The no start has got to be the starter enable relay, am I right? But the chugging and even a little backfire once, I really dont know.
The lack of smoothness in 6th gear will probably be a injector issue. But it could be something as simple as spark going away in a cylinder. But yes, the no start condition is probably the relay. It's up underneath the dash. Easy access.

And not showing a code does not mean somthing is not wrong.

They are the same flow rate. But the clips are different. You need to cut the tabs off of the primary injector

Doesn't matter the mileage. Letting them sit is worse.

Stock - Around 1,000 (good guy price)
RC's - Around 960.00
Accel 150121 - 600.00
