Checking my Hummer H3 fuel pressure with a fuel pressure test kit from my local auto parts store. The H3 shop manual states normal fuel pressure is 57 PSI and a drop of 5 PSI or more within one minute (key on, engine off) is out of specification. Normal pressure with engine on is 57 PSI maintained (bouncing of gauge needle is normal with engine on).

If fuel pressure drops more than 5 PSI in one minute, possible culprits may be faulty wiring, a failing fuel pump assembly, a fuel line leak, or leaking injectors. Each of these issues can be tested simply, so avoid buying parts without knowing if they are needing replacement!
