Had injector problem now no start hp oil leak ... HELP

ok i got some injectors and ive been having problem with them i had a misfire on cyl #1 did compression check it was good, checked harness, it was good took the injector out and sent it back and they said it tested perfect and worked great... when i got it back i put it back in and still missfire on #1 so i took it out and switched with #3 (replaced seals and crush washers every time i take it out) put it together with valve cover off to see if the misfire would move... now it will not run ... i can crank it and it will fire after awhile of cranking but only for 1-4sec then dies when it fires up i seen oil coming from between the oil rail and the injector, i replaced the oil rail and the o rings with c-clips in spool valves and it still will only start for a second or two and i still notice oil leaking from the top of all 4 injectors .... could the spool valves be cracked or damaged and leaking oil..... need to fix asap please help

Since no one has replied yet, I'll throw this out... Have you checked the FCIM? I know it is a long shot, but might as well while you're in there.

sounds like the o rings in the top of the injectors are deteriorated or were cut when you put the oil log on. Take a close look at the o rings in the top that the oil log sits in if they look cut or worn they need to be replaced. The only repair I know of for that is to replace the injectors that are leaking.

We have recently learned that the nipples themselves are replaceable and have a small thin o=ring that can leak. Requires a special socket.

I FINALLY FIXED MY TRUCK THE PROBLEM WAS THE BATTERIES AND THE STARTER .... THE BATTERIES WOULD CRANK BUT WOULD NOT CRANK LONG AND DID NOT HAVE ENOUGH JUICE TO KEEP THE TRUCK RUNNING WHEN IT DID FINALLY FIRE.....I CHANGED THE BATTERIES AND THE STARTER NOW IT IS RUNNING LIKE NEW AGAIN...... FOR EVERYONE WHO SAID THAT THE OIL RAIL SHOULD LOT LEAK OIL IS WRONG IT IS COMPLETELY NORMAL FOR ALL THE THE INJECTORS TO PULSE OIL OUT OF THE TOP OF THEM... THAT IS HOW IT PURGES THE OIL OUT OF THE INJECTOR....COMPLETELY NORMAL.... GOOD LUCK TO ANYONE WHO HAS A SIMILAR PROBLEM..... FYI IF YOU GET YOU BATTERIES TESTED MAKE SURE THEY D A LOAD TEST ON THEM ADVANCE SAID THAT THE BATTERIES WERE GOOD OVER 1000 CCA EACH BUT COULD NOT CARY A LOAD FOR MORE THAN 30-40 SECONDS.....

This is the problem with internet advice. The OP needs to be able to convey any issues that surrounds the problem. Had voltage after the fact and cranking irregularities been mentioned, it is quite possible the advice would have been to look to the batteries first. There are a number of posts where batteries, attachment points, and starters killing the batteries have lead to FICM failutes and rough running injectors.

I am glad you found your problem.
