An old diesel guy told me to crack the injector lines. Listen for the miss. If one doesn't miss, replace it. IE: "you don need no stinkin compression test"
I'd sure like to know what my individual cylinders compression is though.

I did have an ip go out on me and the 1st sign i had was it would not start when up to temp.I used to have to wait 1-2 hours before it would re-start. What milage is on it? If no additives such as stanadyne fuel treatment was used(it adds lubricity to the pump) your lucky to get 100,000.
Good news on the compression though,at least you have some evidence to support putting on a new ip.

Does it have a hard time idling? One thing I've noticed on some bad pumps is they will stall after you snap the throttle and release.

no once it starts it runs like a top. ok 1st thing in the morning say it fires right off. i drive it about 20 miles then kill it. ok now if i try to start it right back say within a minute it will start right up. but if i wait say 30 minutes or so it will not crank off until it cools down. i need help bad its getting embarassing having to crank and crank. plus i cant think of anything else to do about it

If you want to be full sure i suggest removing the ip and take to a diesel shop for testing.Its not that hard to remove except for the 2 bottom bolts.I had to fab up a 9/16 wrench(cut off and weld on a handle).I also found it easier to remove the injector lines 1st.Remember though,dirt is your enemy,even in minute amounts,CLEAN everything before you start. Good luck.
