I'm ***** ***** Pipkin And I have a 2003 Chevy 3500 diesel

Customer Question

Customer: I'm ***** ***** Pipkin And I have a 2003 Chevy 3500 diesel that shows dtc p0370. Won't start before the code shows, I know the circuits are complete to the engine harness connector from the sensors. Should I consider a loose timing chain?
JA: Thanks. Can you give me any more details about your issue?
Customer: good fuel pressure,
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to Chevy Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?
Customer: sure
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
