lraffe1 Posted January 25, 2008 Share Posted January 25, 2008 I had a 350 dump towed in died on road just after different dealer had put 1,5, and 7 in twice within 2000 miles. I got running and found cylinders dropping one at a time till engine stalled. I then preformed balloon test and ballon on left bank blow up while cranking. I replaced left bank inj and fuel pressure regulator. Truck started and ran fine I then took on test drive and found fuel pressured dropped to 15 psi on hard accel. I replaced pump and ran fine. Which leads me wonder how many techs don't realise the importance of fuel pressure and just keep slamming inj. I personal replace the fuel pressure regulator on ever inj job unless I can find records of it being replaced before. After starting to do this I found the amount of inj I replaced dropped by fifty percent. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted January 25, 2008 Share Posted January 25, 2008 This is something we have touched upon many times in that proper diagnostics makes all the difference. A fuel pressure test is not only the smart thing to do but if you follow the diagnostic routine a fuel pressure test is only step #10 on the performance diagnostic sheet. Since it only takes a couple of minutes to set up, why wouldn't you check fuel pressure??? Quote Link to comment Share on other sites More sharing options...
lraffe1 Posted January 25, 2008 Author Share Posted January 25, 2008 I know its on the sheet but how many techs just fill it out to get paid and don't perform the tests. Then they will turn around a month or two later and bitch about it coming back for the same concern. Just maybe Fords atempt to constantly throw there sscs or ccss hell I don't even remenber what it is finaly sunk in on finding the causal part.

Keith Browning Posted January 25, 2008 Share Posted January 25, 2008 Shit, who FILLS out the sheets? For years I did and for what? Nobody has ever asked to see them, have them submitted or refer to them officially. For the most part, I followed them for years and the routine is burned into my brain. I still refer to them for specs and to make sure I am not over looking anything because there are differences among the model years... but, but, but... are you guys ashamed of me? /forums/images/%%GRAEMLIN_URL%%/blush.gif Quote Link to comment Share on other sites More sharing options...
lraffe1 Posted January 25, 2008 Author Share Posted January 25, 2008 I had a manger that had to have one with every truck I worked on. I guess it just became habit and in all the years I worked with him the just got filled with the hard copy to collect dust for 30 yrs. Since then new dealer new manger no sheets. Heck my old manger even went to the trouble to print of enough copies to last yrs for each modela nf put them on my box to collect dust and soak up oil.

Jim Warman Posted January 25, 2008 Share Posted January 25, 2008 I do a diag sheet on almost every repair.... they get stapled to the hard copy. I am not about to have an auditor be the only person to ask to see it.... Quote Link to comment Share on other sites More sharing options...

Brad Clayton Posted January 25, 2008 Share Posted January 25, 2008 Last year we were on shaky ground with Ford and had to mail copies of the R.O. hard card and diag sheets on quite a few repairs. I did a fuel injector recall on the 6.4l and they wanted the valve cover gasket back! /forums/images/%%GRAEMLIN_URL%%/rolleyes.gif Quote Link to comment Share on other sites More sharing options...
