Mazda b2500 non starter
 

Brief outline, its a 2000yr mazda B2500 2.5 diesel , bought it had a few problem including non operational temp gauge, three days latter after purchase cooling system pressurized , rad balloned, head gasket gone and head warped, seller didnt want to know. Managed to purchase a rotten ford ranger complete running car, same year but wlt turbo engine, did engine swap, new rad, starter,fuel filter ,new glowplugs and battery.
Would not run so swapped over ignition, ecu as nit sure if paired to pump. Still wont start, checked timing all good so put new timing belt on. It turns freely and seems to have good compression, have fuel fuel filter ,have fuel in and out of pump and at injectors if i break the lines. It wont even fire up on easy start.WHAT AM I MISSING Live in france, tried to find a mobile mechanic who dont turn up or have less of an idea than i do. Truck does not have after market immo or alarm, have bypassed fuel shut off solenoid so its open . HELP,
