Need to do a fuel pressure test to see what you have.

Check your fuel pressure it should be 60-66 psi with the key on and engine off.Sound like you might have a weak fuel pump.

Changed the grow plugs and top gasket. My diesel ford bantam 1.8 diesel endura engine has failed to start so wat should i mind need yo help. Thnaks

fuel pump ?

Many possible causes....Too little info to make an intelligent suggestion. Try charging the problem vehicle's battery with jumper cables for 2 minutes with the supply vehicle running at fast idle (or about 1500-2000 RPM, if it is tachometer equipped) before you try to crank the problem vehicle on a cold morning. If it starts right up, you likely have a weak battery that needs replacing.

Sounds like the alternator is going out the slow way.
Youre kinda lucky because almoat all alternators go out without warning.
Most Autozone shops or places like it will run a test for free.
Good luck,Gary

hi there
without physically looking at this it is hard to say but best thing i can suggest is that the fuel relay is bad this is a fuse located usually under the hood and will be marked on diagram
hope this helps have a great day

These trucks are known for fuelpump problems. the first thing to check is to see if its got fuel pressure, try sparying starting fluid into throtlbody and see if it starts and runs for a few seconds, if it starts then you will know its a fuel problem, it will die out once the starting fluid is burnt up but at least it will tell you its a fuel problem and if it does start i would bet its the pump. good day.

my experiance has been to find a cracked ignition coil, to check this you need a hande triggered spray bottle with water, open the hood and locate the coil start the engine and spray the coil down with a mist look and listen for an electrical arch or if the truck simply shuts off replace the coil and be carefull(its never happened to me) you dont get shocked

When it wont start one day poor gas or starter fluid into injectors if it starts up it could mean you need to replace fuel injectors.
