Engine/Transmission (1998.5 - 2002) Fuel pressure change

[Rockcrusher]

Fuel pressure has been running 12-14 psi, today its up to 22-24.

I hope its just the cold weather that set in. Havent drove far enough to get it really warmed up.

If you have an electrical gauge the sender may have failed.

my pressure shows low until truck warms up, i agree with illflem that it may be the sender, if it is electric.



ALso check all your electical connections for the gauage. My boost/egt gauage will sometimes act funny if one of the connection is loose.



hope this helps
