2005 lly crank no start after sitting a month
Well I’m guessing it is my cp3, have done all the testing and while the truck is cranking over it only has 300psi rail pressure and they need atleast 1500psi. With the truck having a reman 10mm cp3 I think it may have been weak and that once it dried out it failed the cp3. Bought a new 10mm cp3... -

When I unplugged the fpr it called for 100% but rail pressure was still only 300 psi at cranking. If I unplugged the fuel rail erasure sensor... -

2005 lly crank no start after sitting a month
Wonder why It wouldn’t post the attachment. Still showing code p0090 and a lot of BCM codes and also the u1301 codes for the Data link. Are you talking about the supply line or cracking the high pressure line feeding the rail? -
