Problem: Explain your problem in concise language (Cranks but won’t fire anymore). __thanks for looking the truck won't start. 3 days before it stopped. (before i start about 30 days ago i had to replace the fuel pump solenoid) 3 days before the truck died. when i started the truck. first start of the day. ran normal for a minute . stall. restart. service engine light came on. other than that ran fine all day. i felt like the truck was louder. looked at the owners manual and it said emissions. did not even blink an eye all my stuff is gas. thought it was a sensor and i would be fine till i had some extra money and time. _____ service engine light stayed on from that point on. and. started the truck first start of the day. ran normal for a minute stall. restart. run fine.___the third day. started the truck first start of the day. ran normal for a minute. stall. restart. ran fine. second start about 8 hours latter it was less than 50 degrees it was louder than normal. then a two to four second tapping or rapping. ran normal for a minute then stalled. started the truck ran fine for a mile then that tapping came back. i jumped out with a long screw drive and listen on the valve covers. found the loudest noise i could find. it was from what i could tell the metal lines coming over the valve covers both sides. the noise went away within 90 seconds. when i got home put the screwdriver back on the lines and could hear a tapping. _____the day it died. had to take a dump run truck was full. not a heavy load. first start of the day. ran normal for a minute then stalled. started the truck ran fine. went to and from. took about an hour and a half. did not use the truck again that day or the next day. went to bring it to aamco the following day. codes. and it would not start. now i was very worried. did not hear a hum and no fuel to the filter. replaced the inline pump. still did not start. while under key filter pumped fuel. cracked a injector while under key and fuel came out but it was not squiring out. i don't know if i opened it up enough? also replaced the pump relay no such luck._____codes p0251,P0251 Injection Pump Cam System. p0335,P0335 Crankshaft Position (CKP) Sensor Circuit. p0370,P0370 Timing Reference High Resolution. what does this mean? were do i start? if i do need to rebuild the injector pump or turbo were can i get a full rebuild kit to do this? ___thank you____
