Progress Report on Fixing Paddy - Update Test 15 AGAIN!!

Guys,

Paddy stalled really badly this morning, so I bit the "pride" bullet and called The Diesel Specialist again to have a chat. We both had a laugh, I did indeed have it the correct way round the first time (Still don't fully understand the reasons, but correct never the less). I took Paddy round to his place this morning to have a look at the Fuel Primer Pump as I told to him that it appears to be now leaking fuel more noticeably and wanted him to have a look and confirm the replace part.

The Primer Pump was indeed leaking, he confirmed that it was the 60mm bolt on housing version and not the 100mm, and has ordered one which should arrive tomorrow for $80-$100. If this ends up being the problem, then I'm going to be a little pissed at the previous Diesel Specialist who I had taken the primer pump to at the very start of my tests to check to see if it was leaking. They said they had tested it and it was fine and they did not charge me for the test Hmmmmmmmm...... Maybe with all the priming I've had to do I've just put it though it paces and wore it out ?????? or am I being a bit paranoid, and have the right to think they did not actually test it see Test 8 ????

At the end of the day I don't care, If this works I'll just be one happy camper and glad that its fixed.

Regards
Mark

Progress Report on Fixing Paddy - Update Test 15

Hmmmm Well I think I stuffed up!

Actually I'm hoping I stuffed up and misheard the diesel specialist's instructions. Basically Paddy started fine this morning as per usually after its been primed / bled. But this afternoon after work it stalled.

In my defense I thought it was strange the way I was installing it, between the Injector Pump and Fuel Filter. After all the specialist was indicating that fuel primer / hand pump was faulty (The little metal flappy thing that is part of the primer) and allowing the fuel to run back to the fuel tank so I did have a little alarm bell ringing, in that the value should be between the fuel primer / pump and the tank.

So I think when I heard him say "pump", I've assumed the fuel injector pump but what he probably had said between the Fuel "Hand" pump and the Fuel Tank, it was a noisy environment I was in when trying to talk to this guy.

This afternoon I put the 1 way value between the Fuel Primer / Filter and the Fuel Tank, so lets see if this configuration works :)

Progress Report on Fixing Paddy - Tests 14 & 15

Guys,

Well before moving onto tests 14 and 15, I doubly checked all fuel hoses and clamps, and all where good. Paddy was also due an service so I put on new Oil and Fuel Filters this time went with the more expensive option "Ryco" instead of the slightly cheaper brand REPCO. First morning after service it worked fine, but the next day and each morning after the engine would eventually run rough / lumpy and stall if I did not prime. On the bright side it did not take much priming if I primed early (ie before stall). But at the end of the day, no joy.

So I moved onto Test 14:

Test 14 - Inspecting the Fuel Pickup Line and Gauze Filter

Via the inspection hole in the back of the Pajero I was able to access the fuel inspection cover. After removing 8 x 8mm nuts and pulling the 8mm and 6mm fuel lines off the top, the fuel pickup was easier removed for inspection (Being careful not to damage or break the rubber gasket).

From the following 3 photos you can easily see my tank is clean and the fuel gauze filter was clean and the fuel pickup lines not rusted or have any obvious holes in them to allow air in. I put it back in and bolted down and hooked up the fuel lines and bleed the system. Next Morning the as expected since nothing was really done, the engine ran lumpy and eventually stalled.

Image 1 - Gauze Filter / Mesh looks clean





Image 2 - Gauze Filter / Mesh looks clean




Image 3 - Fuel Pickup and return lines look free of rust and holes.





Test 15 - Trying a 1 way Value between Fuel Filter and Fuel Injector Pump

After have a chat to a Diesel Specialist, he recommended trying a 1 way value between the Injector Pump and the Fuel Filter. He seemed fairly confident that it would address my issue and if I remember correctly on both UK Pajero Forum, a few thread had mentioned using a 1 way value.


Image 4 - 1 way Fuel Value




So for $25 I picked up the following 1 way value and installed it and bleed the air out of the fuel lines. Fingers cross, lets see how it goes tomorrow morning.

Cheers

Farking Hell - The Cold Start is Back!!

Guys,

1 day after posting my "Its Looking Good!" post the car had a hiccup rough idle gave it a rev and all was good, and so I shrugged it off. The next day and almost every odd day since the Engine is back to stalling unless I prime it. So time to continue with the tests:

  1. Firstly I'm going to go back over all the hoses and doubly / triply make sure that they are tight after settling.

  2. Fuel Pickup pipes and Gauze mess Give that a clean.

  3. Blow out the fuel lines make sure nothing is obstructing the flow of fuel

  4. Maybe look at replacing the fuel filter in case I'm unlucky and an obstruction has formed in there.

  5. Reassess my thoughts on having to do the Fuel Pump Seals.



On the bright side, it will keep me entertained a little while longer :) As usual I'll keep you all posted on my tests and results doing one thing at a time till I sort it.

But as I sit here and think, (pray more like it) and shaking my head, I'm still positive its not the seals. I just had 3 weeks of no issues during plenty of -5 degree C cold frosty mornings. Hopefully one of the new pipes clamps just needs a little tightening or the fuel filter has got clogged (please god not with oil ??????)
