We don't have the answer to that problem.

Your fuel filter is likely clogged.

run and earth from the battery to the chassis or engine block and see what happens

disconnect bottom hose on radiator

Hi John, You will need to disconnect the push rod from the brake pedal but do not adjust it at all. Take a flash light and shine it up at the top of the pedal to see if there are securing nuts holding the unit from inside. (I'm pretty sure they're there). Loosen the brake master cylinder securing bolts which will allow the whole unit to be carefully moved away from the servo (booster) unit without disconnecting the brake pipes. Remove the securing bolts from the fire wall inside the cabin and remove the booster. Assembly is opposite to disassembly. regards John

The fuel injection has an engine temperature sensor that is supposed to make the mixture very rich when cold, but then leaner as it warms up. If the thermal resistor is burned out, then it will have too much resistance all the time, and the engine will be flooded out. Use an ohmmeter to measure the temperature sensor resistance. I don't remember the exact values, but bad ones often times go 0 or infinite. And you should see it vary with temperature.

The clutch is controlled hydraulically. There is a master cylinder behind the pedal that pumps fluid into the slave cylinder over the transmission. When it is hard to push down, then it could be frozen hydraulics or a clutch pressure plate problem, but the fact it is also slow coming up means it is only the hydraulics. It could be master or slave. But since the slave is out in the engine compartment where is can rust, I would guess the slave is more likely. I was able to take the rubber piston seals into a clutch specialty shop and they found BMW parts that were a perfect fit, for only a few dollars. To take the slave cylinder apart for cleaning, I would suggest using the fluid pressure to pop the piston out by removing the cylinder but keeping the line attached. If there is any rust, it must be removed with fine emery or steel wool, but all grit must then be washed out. Then use brake lubricant to aid assembly and prevent future rust. If the slave does not do it, then do the master cylinder next. It very rusty and if unable to find a new one, the old one can be chrome plated back to spec.
