2011 Sonata fuel issues
Greetings All,
Anyone know how to check the pressures on the high and low pressure fuel pumps. Trying to figure out which one in bad.

Need a capable scan tool.
If, however, the engine barely runs, there is a good chance the Hi press pump is defective. If it has no fuel pressure at all chances are low press pump.
Most engines will manage to run , barely, with just the low press pump.
