Simply put these engines use an injection system called HEUI or Hydraulically-actuated, Electronically-controlled Unit Injectors. These injectors require a high pressure oil pump to supply the injectors oil pressure to actuate the internal injector piston to push fuel into the system. No oil pressure, no fuel.
if you have engine oil in your fuel injectors then you have bigger problems then your car not starting..
Check for adequate fuel supply to injection pump check for clogged fuel filters kinked ro collapsed fuel and supply lines also return lines from injectors for blockage. And now for the biggy. Its possible that over time the injection pump has worn out. the engine must be timed to remove the pump correctly. while the pump is off have the injectors checked for opening pressure and spray pattern. I am telling you all of this under the assumption that the engine is mechanically sound ie compression and valve adjustment all could play a part. Good Luck!
The original fuel injectors on that model were recalled - did you ever have them replaced?
The 3 series BMW uses a common rail diesel injection system. This means a high pressure pump provides diesel to a common rail feeding all 4 injectors. If one injector goes down there can be insufficient pressure to start the car. The 3 series BMW uses a common rail diesel injection system.

It depends on the cam size, heads, and other factors. 60 to 80 pound injectors will be a good starting point.
Check the MAP sensor, possible culprit.
You can prevent fuel injection flooding by not pumping the gas pedal when trying to start the engine. Fuel injection systems do not need any additional fuel when starting the engine.
Starting with the 1988 model it did
um if it will not idel but start but you have to keep giving it gas... unplug the injectors and try starting it while pumping the gas if it starts you have a leaking injector... if this does not work it could be a bad egr ... or Idel Air Control Valve.. IAC ? hope this helps
No. With electronic fuel injection on today's cars, the fuel system gets fully charged when you turn the ignition key to the on position. This is true whether you are starting a car parked overnight or one that has been run recently.
HI, The best thing to do is check the basic issues that could affect starting. You have already changed the plugs, wires and fuel filter. Have you cleaned the fuel injectors with a pint or two of commercial fuel injection cleaner? Dirty, clogged fuel injectors do not give a fine spray of fuel, preventing the engine from starting easily. When the engine is cold it will missfire and stumble. When it is warm it will run better with dirty injectors, but your fuel mileage will be poor. Also, consider a new air filter. Other, more expensive issues are replacements of fuel injectors, mass air flow sensor, and other sensors that measure and regulate the air/fuel mixture, etc. hope this helpsH
does the engine turn over? if it does, do you have fuel delivery at injectors? has the non starting happened only since the very cold weather? if so, possible glow plug circuit fault or lack of compression!

the electronic geometry gives the rough starting shape of the molecule but once the electron configuration is added it changes the shape of the molecule from the original el.ectronic geometry to the more complex molecular geometry which is a sub-division of the starting electronic geometry
Check fuel injectors & or fuel pump.
Fuel injectors eventually wear out or get clogged. In these case, you need to?æreplace the fuel injector. Failure to change it can lead to bigger problems like poor fuel economy, hard starting, rough idle, and sometimes, having a fuel smell inside the vehicle.?æ
In injection blow molding starting parison is injection molded rather than extruded. In extrusion " " extrusion of parison occurs. There is three steps in injection blow molding: injection, parison and ejection. Tooling cost is higher in injection blow molding. one more, hot knife cut off the resins coming from heating zones before these goes to mold.
Here are a few things I would check. Air filter. Does it need changing. Fuel lift pump and filter. working correctly and clean Carburettor. Are the jets clear and unclogged Spark plugs. Is there a strong spark. Clean and gap set correctly. If it has fuel injection as opposed to a carburettor check the injection pump, fuel lines and injectors. Injection timing. Ignition timing
No. They used Multi- Port fuel injection starting back in 1985 on the 302. Some MPI's are also sequential, but not on the 1993 Bronco.
One of the toys that I can think of is electronic games.

Electronic ignition was starting to be used on enduro bikes by early 1980's.
Ford Mustang - 1983 to 1995 - fuel injection available starting in 1984
