back in the summer it was idling low when it got hot,,pour water over it and it would idle up......but now it will fire straight up but it started acting like the fuel filter was out changed it and the lift pump but its getting worse now after it gets to about 1200 rpm it starts bogging out and hazing.....

More that one time when I worked at a fuel Inj shop. A consumer would come in and tell us it was ilding and I was pressure washing the motor and it quit and won't restart or now runs rough. Don't pour water or pressure Inj pumps unless the engine is stone cold. Fuel Inj pumps run at such tight clearances that cooling the outside of an inj pump can cause things on the inside to seize up like the head and rotor a big $$$ item. Ken

This is one of the first things I learned working at John Deere that your never taught in school. DO NOT ever put water on an injection pump. You can not do this unless it has not been running and is ambient temperature. I was getting ready to pull the head off a JD 4430 and was pressure washing it after it had been running. One of the salesmen that use to work in the shop saw what I was doing and ran over to explain to me why not to put water on the injection pump with the pressure washer.
I have said this numerous times before but some just do not beleive that simply pooring water on a warm or running injection pump can cause damage.

Pouring water on a VE pump when it's running poorly is a very common diagnostic test. If the truck runs ok cold, then runs like crap hot, you pour water on the IP to cool it down. If it goes back to running smooth with the water, the pump is done worn out.
A 4430 has a pee pump.

Wanna find me an injection pump that doesn't use pistons? 
I presume you meant inline pumps. In which case, yes, 4430's use inline pumps. Just because it is a Bosch inline pump does NOT mean it is a P-Pump. The 44 and 46 Iron Horse John Deere's use Bosch A-Pumps. 48's (first introduced in the 40 series) use P-Pumps.
4030, 4230, 4040, and 4240's use rotary Roosa Master pumps.
I may not know much about Dodges and Cumminses, but when it comes to the 30, 40, 50, 55, and 60 series Deere's, I am not the person you want to start an argument with.

I use the term "pee pump" loosely in place of "piston pump" or in your case "inline pump." Mainly because I like saying pee. I'm not arguing with you. I was pointing out the difference in pressure washing an INLINE pump vs pouring water over a ROTARY pump for diagnostic purposes.
While I'm sure you're much more knowledgeable on the mechanics of the deeres, we've had a 4430 on the farm since I can remember. Stole many a summer day from my childhood, haha.

The main point here is it doesn't matter what style or brand injection pump it is, it's not ok to apply water to it when running or even luke warm. I don't care if it's a common diagnostic process for some.
How would you ever know the difference if the pump had failed or failed simply beacause you poured water on top of it. Chances are you had a perfectly good pump until the point in which you just placed water on top of it while it was warm. Now you have a pump that is not any good, not beacause it was worn out but simply beacause you decided to troubshoot it with a bucket of water.
But that's ok troublshooting things in that manner are what keep things in my shop so keep on keepin on, water and all.
As a side note redneck is spot on with the 4430 having an A pump not a pee pump, just an fyi.
