Hard starting 24valve
Have a 2000 Dodge sport. I recently put a new vp44 last yr.had a 1yr warranty and is now over. Once i put my new vp44 on it started fine nd i was getting around 18mpg.so i was happy.now,roughly one yr later i'm back to the same spot i am now.Hard starting after the truck is warm.getting pretty bad mpg.seems like i put 1/4 tank in and it seems u can c it go down as u drive down the road.I dont c a fuel leak anywhere.i do have a chip.and a little bigger injectors.(120 bullydog injectors).i also put on a ddrp02.Put a new airfilter on.put lucas injector cleaner in my fuel.I do have one code that came up.my (tps sensor)p0121.i havent replaced it yet.i cant bring myself to spend 350.00plus for a piece of plastic.I need help guys.I need suggestions/help.If i cant get this figured out i may have to bite the bullet and take it to cummins nd spend the big money to get this fixed.if i cant figure this out i may have to put my truck out on the market,but i dont want to to that cause i love the truck to death.Any help would be greatly appreciated.thank you

What fuel pump are you running and what is your fuel pressure at idle, driving, and WOT?
Why did you replace the first VP and who did you get it from?
Does it only hard start when the engine is warm?
