SOURCE: where are the fuel injectors on a 2003 2.0 ford transit diesel

The age of this transit should be a self bleeding system. But if not, you will see some metal tubes running into the cylinder head, with nuts at the end. Loosen these and crank the engine over until fuel spurts through. You will only need to do 2 or 3 to get the engine started.
I have personally used a damp start spray, in the air inlet to fire up diesel trucks before and not needed to bleed the system at all. Worth a try, just open up the air filter and squirt some into the inlet, crank it over and it should start.

i have a 96 2500 and i have found that if both batteries are not hooked up with a really good connection that the fuel shut off relay will not engage . it will just crank and crank with no start. it is located on the driver side of engine just about the center of the engine .its round and has a chrome rod coming out the bottom of it .it is mounted with the rod on the bottom .you can move it by hand but it will not lock in place unless you have the ignition switch in the start position. there is a couple of relays for it mounted on the fire wall .hope this helps someone

If your car is fitted with Manifold Air Pressure sensor (MAP) check that is operating OK. Sometimes if this is as at fault it can send the wrong signal that the engine is running lean and the engine computer (ECU) in turn compensates by injecting extra fuel. The clouds of smoke are unburnt fuel so not only does it look bad but it is wasteful/costly. The fault on a MAP can evolve slowly and therefore evades the computer diagnostics check for some while before being picked up. Also on the list of things to look at are:- 1) the mass air sensor on the air filter ducting 2) the EGR exhaust gas recirculation valve (perhaps needs a thorough clean) 3) the differential pressure feedback exhaust (DFPE) sensor - lies upstream of the EGR but if faulty can combine to lead to errors in fuel injection quantities.
