Experience is generally a good thing when troubleshooting; it can lead one to the issue sometimes immediately. But! If guessing at the solution proves not to be the case (fix), it"s back to the basics time!



FUEL PRESSURE (static) = ?

Current draw on the pump diagnostic test point (red wire about 5cm long w/ a black terminal sticking out of the large wire loom near the W/S wiper motor) when ignition key is in the OFF position [8-10 amperes is normal for both pumps running nornally].



Let us know what U find...

Hi Paul . So the amp draw is only 7 amps and the fuel pressure reading was at 47 psi [emoji849][emoji3525][emoji853]
