I am guessing a D24 engine? Who put the injectors on? Did you get the programmed? Because it is the Delphi System, you most likely need a new pump and Rail too.
Did you test the battery? Because if the voltage drops during cracking to lower then 10.5 Volts, the ECU will not "fire"!
Also did you replaced the Fuel Filter?

 

[Tarrantequityllc]

Yes d24
Injectors are from man and are programmed also factory fuel pump installed
I will check battery it is week from turning and Messing with it so much.
Yes filter changed

 

[fortworth-cowboy]

Ok, who diagnosed that it was the injectors? Was the Rail and the Tube Lines also replaced?
And when they programmed them, did they run any after Tests? MDP learning?

Field mechanic I called, rail not replaced, everything else done according, once he installed and programmed injector ran rough and we couldn't get running again, I now have changed fuel pump and still nothing, today I sprayed starting fluid and she started right up and died once fluid went dry….

Don't do starting fluid, Common Rail Engines do NOT like that!
How did he determine that the Injectors were bad?
These Doosan D24 Engines with the Delphi System on usually don't fail just the injectors, the HP Pump goes bad and sends metal through the system, that's why you have to replace the whole system.
Was the Field Tech from Bobcat? Because if not, he can not have the correct software and hardware.
Most likely you have replace the 4 Injectors again, the HP Pump again and this time the Rail too, because he for sure did not clean the rail out.

Water had got in system a while back…

Ok, so you most likely have water in the fuel tank too.
And you need a whole new system, lines, rail , HP pump and all injectors

Had a guy field tech, from bobcat show up, so far we have put new injectors, he verified they were programmed correctly, new injector pump,
New fuel rail with sensor, and he could not get it started either, said compression was good, recommended take it to the shop to have them go through it….

Does it start with the Drive Belt off?

No start, we tried that the other day, I think we have pretty much run out things to do at this point, thanks for your help.

Did he do a compression test manually or on the computer??

 

[Tarrantequityllc]

Computer

 

[fortworth-cowboy]

Computer

Then this Field Tech is dumb, sorry. The computer compression test never fails and is not even checking the compression. You have to do a manual compression test through the glow plugs or even better through the injector opening.
Are these field techs from Bobcat of North Texas?

 

[Tarrantequityllc]

Yes that's correct here in N Fort Worth, He suggested fuel rail sensor since the reading of psi was not to where it should be according to the tech

Did he do an Injector Static Test? With Tube lines to see if one or more injector are bypassing the fuel?

 

[Tarrantequityllc]

No he did not.

Do you know a mechanic I could call to check
My machine out. Here in Fort Worth

Not really and I am fare from Fort Worth--45 min-50 min

 

[Tarrantequityllc]

Gotcha. Thanks for the help though!
