troubleshooting your vehicle without ever looking at it (Impossible)You can tell some one how to troubleshoot but your not really doing it are you???
A: Using the socratic method, I will allow you to help yourself. Since you have concluded that it is impossible to troubleshoot a vehicle without actually seeing, hearing, touching, tasting and smelling it.. Q: what do you think you are getting when you ask the parts guy for help… (Hint: two words, first starts with “B” and the second starts with “S”)
When did fuel filters get knocked off the simple/routine maintenance list?
A: when they are in-line, hard to get to, and require the use of special tools to remove them.
Wrench everything Ford is saying is right…
Fuel filters can cause issues with out registering on a fuel pressure tester.
A: Very good. you are correct. and you are at least the 3rd person to have mentioned this. Therefore, it is important to measure fuel flow as well as static and dynamic fuel pressure in efforts to determine if the fuel pump is failing even though it can deliver proper psi. Other testing such as injector balance and current ramping could also be performed as necessary. Check my previous posts on how to measure volumetric fuel flow. So, in summary we can state that we can all agree that it is possible for a fuel pump to deliver proper psi but not at the proper rate.
I dont feel this is the place to insalt some one
Q: would you like some inpepper with your insalt.
I never said the fuel filter should not be replaced. I simply stated that if there is proper fuel flow, then the fuel filter can be eliminated as a possible restriction. If you are in elbow deep into a fuel system issue, it may or may not be worth your time to change the filter. This will depend on several variables and is up to the owner’s discretion; however, in this scenario one cannot conclude that the fuel filter is the source of the problem given fuel flow was tested and was found to be within spec. Yes, it is probably a good idea to change the filter solely as an act of preventative maintenance. How much time and money you wish to throw away is your business. Will it fix your starting problem? No.
Why waste time on something, when something else is the problem.
We work for flat-rate people.. work smarter, not harder.
Time = $$$.
Btw, This is me current ramping a 2004 dodge ram 1500 5.7L Hemi fuel pump using a very expensive Bosch scan tool; 10 commutator segment fuel pump. Thought you might be interested.
oh, and I apologize in advance for “telling it like it is.”
