Question about 1987 Mitsubishi Passenger

1 Answer

Air in fuel line?

HI Guys, my Pajero starts fine first kit over every time. The primer is hard before I start, then the truck starts starving and shaking around blowing clouds of smoke. I then have to pump the primer as its soft. This is getting progressively worse and now not just once but twice or three times before it will stay running. After priming the first time I will normally get a KM down the road until it dies again. Once over the initial 2 -3 primes it runs fine until left stoped for 3-4 hours. I'm guessing its air in the feul system somewhere?I Have replaced some of the hoses. A machanic wants to charge me $2000 saying its an internal non return valve and labour intensive. This doesn't make sence to me as the primer is hard prior to start as if air is getting in prior to the primer and being dragged through???!!!! ANYONE ABLE TO HELP? please, thanks John, ps its a mitzubishi pajero 2800 deisel

Get a container with fuel(about 4 liters will do). put a hose from the Primer to the fuel container and another hose from the injection pump return line to the container. if it works fine then the air leak is between the tank and the primer.

How do you bleed the diesel fuel filter on a 1986 Toyota diesel Land Crusier?


I don't know a lot about these trucks but I can tell you that somewhere between the spin-on fuel filter and the I.P. (injection pump) is a 1.5" dia X 4" long steel primer. Just under the top of it is a spring. You will need to loosen or open the "Fuel supply line", at the I.P. (going from the filter, to the pump) and manually pump the fuel primer. Continue pumping the fuel primer until diesel flow from the opening. Quickly close off the drain-port or fuel-line, pump the primer a few more times (to increase line pressure and try to start your vehicle. After it starts, check for leaks. Let me know if I can help anymore. Good luck.

Very hard starting, also stalls intermittently. seems like starving for gas at times


Probably is starving for fuel. Replace your fuel filter. Most cars it is near the rear passenger tire. Follow the gas lines near the rear. Most of the time they are long as your hand and round, and black. Almost guarantee this is your problem.

I have 93 pajero 2.8 diesel.it starts fine in the morning,but when i drive off it gives the impression it has run out of fuel.It will then start, but not easily and it can do this a couple of times before...


Hi ..... It sounds like you're getting air into the system overnight. Diesel won't come out but air will go in. Check the fuel filter is on tight and that any soundproofing on top of the engine hasn't caused a stress fracture in/on any of the injector lines. Find where your manual primer is and before you start it in the morning give it a couple of pumps. What I have seen in the past is the positve live feed to the pump corrode (green) and after cleaning and tightening up the crimp all is fine.
Let us know the outcome.

I have a 1988 dodge ram it wont start it will start on primer then shuts off i replaced the fuel pump and filter but still wont start could it be air locked can you help me please thank-you william


Sounds like it's fuel starved. It will be TBI, there's another fuel filter bolted to the chassis, about mid way, drivers side (looks like a small metal can, with to hose fittings). Any fuel leaks anywhere, rusted out fuel or fuel return lines? Air starved? Replace your air filter. A bad coil will cause this too.
