Replying to: guyk (Oct 18, 2007 2:37 pm) Just got mine back from the Dealer and he told me that it was the lift pump and injector pump. Which they can replace for $3500.00.... Yikes!!!!!! Unfortunately, they cannot tell me how they came to that conclusion. The truck is running so I am going to replace the lift pump first and install a set of pressure gauges to monitor the fuel pressure. If the problem persist then I know to replace the injector pump. Email me at jcobarruviassatx.rr.com and I will let you know how I made out. Replies to this message: 0patience (Oct 19, 2007 3:42 pm)

Replying to: orchiddj (Oct 15, 2007 9:06 am) If I knew a good honest mechanic I would take it to get looked at but am afraid I will get ripped off. Ouch, that smarted. Ok, how did you test the glowplugs again? Are both batteries in good condition? Yes, they will have an affect on the glowplugs. Next thing, check that the return hoses aren't falling apart and collapsing. They are the rubber hoses that go across to each injector. Any leaks at the injectors? When it finally starts, how bad does it smoke? How many miles are on this engine? Ok, now that I asked a bunch of questions, a WAG would be that you have an injector or 2 that are leaking down. When that happens, it has a flooding affect and can cause similar symptoms.

Replying to: jcob (Oct 19, 2007 5:25 am) I've run into several where the lift pumps were failing and several where the owners had allowed the fuel filters to stay in too long and caused power loss problems. But, without knowing what they did and what they checked, it is hard to tell.
#81 of 146 Injector problems? by pstory Oct 25, 2007 (7:23 pm)
I have a diesel vanagon and think I have an injector problem.When I go to start it,the rubber fuel return line and or the rubber plug fly off due to excessive pressure and fuel flys everywhere. the vehicle starts and will still run roughly but it appears as though the pressure is dumping large amounts of fuel through that injector and consecuently blowing off the return line.Is my injector in need of repair?Please help!!

Replying to: pstory (Oct 25, 2007 7:23 pm) No, more than likely, you have a blockage in the return. Which would cause pressure on the return line and blow the hose off. I would suspect one of the rubber return hoses has collapsed. I seriously doubt you have an injector problem. Fuel runs through the injectors all the time. The injectors don't regulate preussure, so you are on the wrong path.

Replying to: 0patience (Oct 19, 2007 3:39 pm) I have a '92 7.3L IH diesel, 141,000k miles. I can't answer your question, but my truck does have a harder time staring in colder weather (I'm positive it is time for glow plugs as they have 90k+ on them, but lonts of long distance driving). It is currently in the shop because the the fuel filter/water separator developed some really bad leaks at the point where the wires enter at the top to heat the fuel, and the drain tube off the bottom busted off. Simultaneously, the braided fuel line developed a pin hole and sprayed fuel all over. It took them a week to find the correct parts (fuel filter and wires, etc). I just got off the phone with my mechanic (who hasn't done me wrong yet) and he mentioned that the rubber hoses to each glow plug (or did he say injector) are OEM, look bad and need to be replaced. Which sounds like the same thing the mechanic above mentions.

#84 of 146 Jelly gunk in fuel tanks - lady needs advice by cayadopi Nov 24, 2007 (8:16 am)
'92 Ford 7.3L diesel, 2 tanks, ~ 140k miles, almost always in S. FL. Both tanks about 1/4 tank full of some kind of junk that clogs the fuel lines and starts to cut off the motor if I let the fuel tanks get too low. 1) I see ads for additives for anti-gel and anti-fungus. I've tried the anti-gel but it doesn't seem to work. Should I try anti-fungus additive? 2) Is there some way to suck out this gel with a vacuum hose or pump? 3) I plan on keeping the truck at least another 100k miles baring any complications. Should I not worry about this as long as it doesn't get higher than 1/4 tank? 4) I am pulling a 12k pound Fifth Wheeler. Is there any possibility of some amounts of gunk getting sucked up thru the fuel lines and causing other problems? (i.e. I just had to replace the fuel filter/heater/water seperator & wiring to that), and rubber fuel line just popped a leak same time. Is it possible that some "gunk" is causing some kind of back pressure? 5) Should I pull the tank and get it cleaned out? The truck is still at the mechanic. I don't mind spending the money. Have had this old truck since day one. Replies to this message: Mr_Shiftright (Nov 24, 2007 10:00 am) cayadopi (Dec 10, 2007 1:08 am) Mr_Shiftright (Dec 10, 2007 9:08 am)

Replying to: cayadopi (Nov 24, 2007 8:16 am) You don't have gel, that's a cold weather issue. You probably have of all things---algae! You need what they call a bio-cide. If the grunge is too thick you probably need to drain the tanks and replace the filters. Otherwise, if you don't drop the tanks and have them cleaned, you'll be hassled in the future. Your filters can't trap THAT much junk, if you have a great deal of it. Replies to this message: cayadopi (Dec 10, 2007 1:08 am) Mr_Shiftright (Dec 10, 2007 9:08 am)

Replying to: cayadopi (Nov 24, 2007 7:32 am) Your glow plugs are WAY overdue. Diesels by nature have a hard time starting in cold weather. They need optimum glow heat and optimum additive protection in cold weather. So new glow plugs, fuel conditioner (anti-gel) and new hoses if they are leaking or cracked.
