was wondering if any one has had a simular exeperience and or answer a question for me. I have a 1988 Ford with a 7.3L Navistar. When I bought in last july I had to do some minor work on it to get it going like changing some of the glow plugs but a problem that I had was that after sitting for about 4 hours it would not start without prolonged cranking. I know I should have done something before but as used it infrequently I just sprayed a little starter fluid in the intake and waited untill the glow plug relay stopped cliking then started right up. Then I threw another monkey wrench in by starting using biodiesel in it(B20). After the second fillup comming home one night it started making a rattling noise and was overheating a bit. stopped and checked oil level and antifreeze levels. both were a little low so topped off. Continued down the road about 9 miles to my exit off the freeway and the rattling noise continued to get worse. I then parked it at a resturant a had it towed home the next day. I then changed the fuel filter thinking that the biodiesel had clogged it up. but to no avail the truck will not run. Could the injection pump have been going out and I just put the final nail in it's coffin when I went to b20? [img]/ubbthreads/images/graemlins/shrug.gif[/img] any Ideas? thanks for your help.
