What's up guys? I have a 99 ranger 2.5 with about 150000 on the odometer. I was getting a p0107 code Ford a long time and truck recently began stuttering and surging. Cleaned maf, new intake gasket, new throttle body gasket, cleaned injectors cleaned and checked all other sensors. Couldn't check fuel pressure until afterwards because I didn't have a gauge. Checked pressure and it is only reading 15 psi on three key turns. Can hear pump turn on and relay click. Could this be a bad fuel pump or something in the system elsewhere. Thanks in advance!

Disconnecting battery while checking everything else reset cel if that makes a difference.

The pump is most likely bad but recheck the pressure first.

I did a voltage drop test on the fuel pump this morning and started at 12.5 volts, key turned in the voltage dropped to 1 volt. Could a bad pump cause the huge voltage drop?
