Question about 1990 Daihatsu Rocky

Open Question

My 1990 daihatsu rocky runs ok when cold. As soon as it warms up a little,it starts to miss. If i try to rev it up, it bogs out and dies

I already cleaned out fuel filter. As engine starts to warm up, you can actually hear it make a clicking noise and the sound of motor instantly changes for the worse

Errors codes would be the logical thing to look at first. You may need to ask Toyota for the procedure in retrieving them.

Check that there aren't any obvious cracks in vacuum hoses.

Try pinching the PCV valve hose. If it stabilises you need to clean with some carby cleaner or replace.

The H series engines are prone to this and can generally be tracked to a vapour lock in the coolant hoses on the throttle body air valve (idle circuit).

There is a small cone shaped fuel filter located just before the fuel pump. It is inside the rubber hose that attaches to the pump. This is an often overlooked/unknown filter as there is another large one located on the firewall. Most folks change that one without cleaning the cone shaped one. Good luck!

SOURCE: Daihatsu Rocky will not start.

Take the fuel line off the tank side of primer and connect a plastic jar full of diesel there and see if it starts. If not disconnect fuel line from primer side of fuel pump and see if fuel gets through to injectors. If not problem is in pump. If you have fuel and still wont start it will likely be glow plugs. You can short them out with a wire from positive battery terminal to plate joining all glow plugs. (make sure you disconnect it after 30 seconds or so or they will burn out) The engine will probably not start at all if the glow plugs dont work. (all this advice is from experience)

Good luck

Engine keeps cutting out , like its a fuel problem , but then it will start back up after a few turns of the key , but then stall again ..... engine will run all day on tic over , soon u drive it , it will...


It's most likely drawing air around the fuel filter housing. To check it take the two off the top of the filter housing and joint them together giving it a direct feed from the tank to the pump. Start it up it should run fine. If you have been working at the fuel filter before you had the problem then you may have put the pipes back wrong way round this will cause it to idle and not rev. up as well.

Cold starts ok warms up shakes and stalls


check engine coolant temperature when it gets warmer, or at operating temperature, and verify that the temperature gauge is showing warmed up to operating temperature. If the coolant temperature sensor tells the computer the engine is cold it will over fuel and miss and the engine will die. When cooled down it will run fine until it warms up. Also could be coil if it starts missing after warmed up.
