2005 Ford Fiesta 1.4 TDCi not starting Sign In

Hi all,

i have a 2005 fiesta 1.4 tdci.

last thursday i wanted to change the glow plugs, disconnected the fuel hoses at the top of the engine.

The second glow plug broke in, so i thought i leave it. Connected the fuel hoses back, pumped it up, and everything was fine, i went 3-4 miles with the car.

Friday i wanted to go, but didn't started. I tried to crank many times, pumped up the fuel, it started twice, but after 5 seconds, it died again. Then the battery died, so i went to recharge it.

On saturday i tried to start again, but nothing. Disconnected again the hoses if there might be some air, connected back, but nothing has changed.

When i started the car, i got 3 faliure codes:

P0191 - Fuel rail pressure sensor

P0336 - Crankshaft position sensor

P0380 - Glow plug(but this is old).

While starting the car i watched the fuel rail pressure:

It went up to 200+bar(3000+psi), then suddenly back to 20-30bar(300-450psi). Sometimes it was constant 200+bar, and that time i didn't get the P0191 message, but the car didn't started.

Next day i tried to start the car, rail pressure was 200+bar, did not started, but no fault code.

Later i tried again, same.

Then later again, 3rd time, and it started immediately, everithing was the same as before, and i let it run for 5-10 minutes, it was ok.

I stopped the engine, and a few seconds later tried again, no problem, everything was ok, no fault codes, no weird noises, so i stopped the engine.

About a half an hour later tried again, but it did not start, the rail pressure went down to 20-25 bar. First no fault code, but then i got the P0191 - Fuel rail pressure sensor code.

I deleted the fault code, the i got back P0336 - Crankshaft position sensor.

Yesterday i have changed the crankshaft position sensor, everyone said that is the problem. No difference. Still not starting. Tried about 3-4 times. Rail pressure was always about 24bar.

Why the rail pressure goes down? What can i do about it? Is it normal, that it's changes so much? I think this is the reason of the problem, but how to solve it?

We don't really have anyone here that specializes is diesel. It's not that common here in the US.
