in jan i installed a new fass lift pump because my factory one went out, the truck had 204k on it so i went ahead and replaced the injector pump also. every thing was going good intill a couple of weeks ago. my tack went crazy and i lost power in the truck going down the road, then in a couple of miles every thing was alright. the check engine light came on and the code was for the cam shaft postining sensor. before i replaced the sensor the truck was hard to start. and after i replaced it, it has gotten worse. now when i have to start it , it takes a couple of times of the lift pump going on for 25 sec to start it. the truck has power when it starts and runs and idles fine. If anyone can help it would be appreciated

it is harder to start after I run the truck, it will take a couple of times cycling the lift pump and then after that still have to crake it for at least 10+ sec , it doesnt matter if i run it for 1 hour or all day, and as sone as i turn it off and try to start it back again it will do the same thing. but in the morning it only takes one time cycling the pump and it fires up quick.
