    Dimensions of fuel pump motor

    If the amps were lower than published expected value, I would suspect a restriction in the line between the pump and the access point on the fuel rail. Remember that a centrifugal pump does the most work when pumping full flow and the amps should be high. When the volume being pumped decreases...

    Fuel Pump assembly collar

    Did the new o ring appear to be the same cross section as the old one and about the same diameter? Maybe try installing the lock ring with out the pump in place and identify any fit problems. This style of ring has been use for many years. Maybe this one has a tab that will prevent the ring...

    I would be tempted to put the occillisope on the pump leads and see what the volts and amps are doing during operation.

    Plastic Engine Cover

    I believe the tower is glued in place and not considered replaceable and not available. the metal insert can be removed with a puller, but finding a replacement may be another problem. The bore of the tower is already damaged by the insert rotating, as the cap screw is turned to remove and...

    The larger the bore, the more foot power needed. Vacuum applications may not provide adequate stopping power.

    Ran out of gas now wont start

    Do you know if the tank is empty or if the fuel pump stopped working? What does the gauge indicate? Can you hear the fuel pump running after the ignition switch is placed in run or start? Did you see the "low fuel" light before the engine stopped running? Not sure if o2 models have the time...

    04 Yukon XL SLT Can't find AC leak after collision with Deer

    Just add a small amount of refrigerant, 1/2 can or so may be enough to find a small leak. Have a spray bottle of soapy water to spray on every thing. The bubbles will show the leak.

    Aftermarket Intake trouble shooting MPG

    You probably already checked the injectors. I was thinking about pulsing each injector and recording system pressure drop for each one. If that test did not reveal any differences between injectors, I probably remove them and measure the amount of gas each one puts out. There is probably...

    I want to replace my ignition coil, which one do you recommend Tahoe 5.3 2007

    What was serviced 3 days ago? Did you add oil and refrigerant to the system? The AC compressor wants to pump vapor not liquid. The correct amount of refrigerant and correct oil for the refrigerant are critical to correct operation. Did you add oil thru the suction line?

    Normal AC clutch function?

    Yep, having the correct charge of R and air flow across the evaperator help keep pressures in operating range.

    I want to replace my ignition coil, which one do you recommend Tahoe 5.3 2007

    Check the refridigerant pressures and determine compressor function. The high pressure may be low if the compressor is not pumping sufficient flow and presenting a high load. When the clutch is engaged, the compressor and clutch rotate as one unit.

    I want to replace my ignition coil, which one do you recommend Tahoe 5.3 2007

    Do you still have the orginal air intake housing, filter system installed? Does the front o2sensors on both side react the same to WFO throttle action? (WFO is wide open.) Can you do a leak down test on cylinder number 2? Have the volm cover been removed? Does the engine have the DOD...

    Lifter Failure Root Cause Same as HEMI?

    Good photograph of the lifter. I find it interesting that the almost never shown component related to the failures is the little oring that seals between the block tower for each cylinder, and the volm assembly. If this oring is damaged or re-used, a leak of oil occurs and the lifter cannot...
