Hi Peter, If the vehicle turns on the starter all the time, and sometimes starts and other times fails, check the fuel filter for leakage. Sometimes air gets into the fuel system. When it gives problems, open the bonnet (hood) and have someone pump the pump on top of the filter housing. If it feels soft when beginning to pump, I would suspect either a leakage on the fuel line or the filter housing. If you need to replace the housing and filter, remember to fill the replacement filter with clean diesel fuel first. the glow plugs can also cause problems if one or more have burned out. Regards John
Here is what my Haynes Diesel Engine Repair Manual says for a noticeable lack of power, which is what you are describing.
1. Blocked air intake
2.Incorrectly adjusted timing
3.Blocked or damaged exhaust system
4.Obstruction in fuel filter
5.Blocked fuel tank vacuum vent in fuel cap
6.Insufficient fuel supply from tank to injector pump
7.Obstruction in fuel tank filter
8. Pinched or restricted fuel return line
9. Incorrect or contaminated fuel
10.External compression leaks ( glow plugs or injectors)
11. Obstruction in injector nozzles
This book has an excellent diagnosis and repair section for your engine. It's Haynes part #10330 and costs about $20. Hope this helps.
I would suggest that you have a blown head-gasket. The Z24s have a tendency to blow the head-gasket between #3 & #4 cylinders. I would do a compression check. You will probably find low or no compression on those 2 cylinders.
Yes, the fuel is bad after 5 years. The only way to do this properly is to drop the tank to get sludge and sediment out, as well as flushing out the fuel lines, replacing the fuel filter. If you don't do this, you will have nothing but trouble until you do. Check the brakes also. Sitting this long, the calipers/brake cylinders probably have frozen. It would be a good idea to flush out the brake lines (bleed all wheels until 'new' fluid flows through. This might save the brake system from overhaul, and it will have to be done it you do overhaul the brake system anyway. Good luck, it is a good sign that it cranks and runs on starter fluid, but you have quite a bit of work to do.
If it's been sitting for that long, yes the gas goes bad. Drain the tank, fuel lines and even the spark plugs becuase the old gas will foul them too. Check air filter for free air flow and possible critters living in the intake... two years is quite a while for a car to sit... Also after it's running have your oil and filter changed as well.
I would definately check around the intake gaskets with any spray lubricant or cleaner.Do this while the engine is running. If it starts to stumble then concentrate the spray until you pinpoint the area of fault. This is all I have to offer without being there. Good luck,Dana
if the car is fule injected thear will be valve that looks like an air valve on top of the engen on the fule line you can use this to bleed out the air in the line. do this with key on DO NOT RUN OR START the engen untill finished bleeding system and spiled fule is clend up and dry
Hi, The carb is gummed up from sitting. The best solution is to take it apart and clean it. The starter fluid indicates that it has clogged jets or stuck floats. The good news is that if it cranks with the starter fluid everything else is probably OK. Good Luck!
