    remove the large metal canister diesel filter. fill it with diesel fuel or if diesel fuel is not available fill it with transmission fluid and reinstall it. the mechanical fuel pump is non positive so it cannot suc out fuel from the fuel tank if it is empty. u need to prime it first. also pump a battery charger on the car and keep cranking it after u prime the filter with diesel or trans fluid.

Toyota soarer twin turbo 1991 model running rough any ideas as to what may be causing my car to play up like this?

Hi Chris:
I'd start with standard maintenance procedures:
- Air Filter
- Spark plugs
- Fuel delivery system clean.

Depending on milage and maintenance history, a 1991 engine will be starting to display signs of age. Valves, timing linkages, rings, etc. age creeps up on them. "Rough" is usually associated with mis-firing. That leads it spark and fuel as the primary check, and then compression as the secondary diagnostic that I would be looking at.

Hope this helps.

My '84 Mercedes 300D Turbo diesel has become incredibly sluggish since i changed

that sounds like the fuel return hose on one of your fuel injectors. You should get about 2 ft of hose and replace all of them including the one in back that is capped and the one to the injector pump. Im guessing when this happens there is fuel everywhere?

Can you tell me the oil capacity of the 5 cylinder inline engine.

I presume you have the 300D diesel. If this is the case, you will need 6 quarts for non-turbo, and 8 quarts for the turbo 300DT. Both include a filter change.

1997 300D sometimes cuts out when brake or indicator is touched.

Next time when it cuts out,check the primary fuel filter.
It should be 1/2 to 3/4 full.
If it's below half then the intank 80 micron filter screen filter can be clogged.
Are you using bio-diesel or bio-diesel blend?
In general, change the in-tank,primary and secondary filters will fix the problem.
