1999 Ford Ranger with low power and lean exhaust codes (P0171 and P0174) This was one of the most bizarre customer complaints I have had in my 25 years as a mechanic. The complaint was low power but only with the headlights on! To be honest, I thought the guy was on something and I totally disregarded his complaint. I thought to myself "there is no way turning your headlights on can be associated with a low power complaint", I think I even told him that. But this one humbled me for sure and the

Proper fuel pressure testing should include a volume test, a bleed down test, cranking pressures, as well as fuel pump power and ground testing. This quick video covers all of this and more. For more automotive diagnostic training visit my website www.scannerdanner.com Here is the link to this full length video on YouTube https://youtu.be/PvAcjWXJu94 BTW this truck is fixed and I was able to film the after repair data. I will have this uploaded after we complete our Mustang series. Thank you! |

Be careful of the "unplug it" test of a MAF sensor! Just because fuel trims normalize, does not always mean the MAF is the issue. This clip was pulled from a recent SD Premium video on my website. | ScannerDanner

Fuel psi is in spec at idle. Is that good enough of a test? ABSOLUTELY NOT! Weak Fuel pumps can keep up during times of low volume (idle), so psi must be tested during high volume conditions. 1. snap throttle to wide open/redline RPM and make sure psi doesn't drop during the rev 2. also check for a bleed down issues https://www.scannerdanner.com/join-scannerdanner-premium.html | ScannerDanner

Hot tub circulation pump question. Laing or Goulds E10-NSHNDNN2W-02 6050U0016 230V 50/60HZ max: 60w IP55 29 PSI (2bar) 140°F (60°C) PD 46/19 EP My question is on the LED trouble code the motor is indicating.
