1996 Ford Escort 1.8 TD Fuel Pump Adjustment?

I don't think you want to mess with the fuel pump unless it's failing. It's job is to deliver fuel under pressure. Supposedly, the mixture is controlled by the computer, so, you may have a bad sensor or two or just a simple case of a wire off.

First thing you could do is a tune up or at least replace the air filter. You may need to put it on a scanner to allow the computer to tell you of any problems that it has.

The fuel pump is a fixed displacement type and cannot be adjusted. There is a pressure regulator in the fuel system that regulated the fuel pressure, again this in not adjustable but can be replaced if suspected.

If the car is running lean then there may be a requirement for the injectors to be cleaned as over time they get blocked up. Take the car down to a diesel specialist and let them have a look at it.

Black smoke - is an indication of a fuel problem.

Blue smoke - is an indication of burning oil.

White smoke - is an indication of water - possible head gasket failing.

It is possible to "tinker" with the injection pump settings but is a rather foolish thing to do. You are likely to do more harm than good.

Take it to a diesel specialist and get it done right.

First thing i need to know is it a bosch or roto diesel injector pump(easy way to find out bosch has what looks like a large turut ontop and roto diesel is flat on top with throttle arm the higest point.

the mondeo's with that engine used to suffer with the timing advance solenoid that lives on top of the pump, speak to local diesel specialist they will find the problem quicker as they deal with diesels all the time.

Might take special tools let Ford Dealer do it.
