im just going to chime in here as i have about 50 or so diff pieces of equipment and vehicles all runiing b 100 i have yet to have any failure of any kind (im sure i just doomed myself) injection pump related in any of my vehicles or equipment ranging from late seventies to 2007 duramax have you taken the vehicle to someone who could check the onboard comp with a code reader to see if you have any fault codes stored??? i f so it might narrow down your problem area,,, because of the price to replace injection pump i think i would at least have a code reader hooked up to see if you have any injector pump related fault codes > Date: Wed, 29 Jul 2009 12:16:02 +0000 > From: [EMAIL PROTECTED] > To: sustainablelorgbiofuel@sustainablelists.org > Subject: Re: [Biofuel] Causes of fuel injection pump failures > > > Thank you for such a good information.
