Thread: No start 200TDI (Injector pump)?

could be as simple as a bad earth,

could be the lift pump not priming

could be a blocked filter. and the extra RPM gives it enough to go.

you could also have an elec issue that stopping the power to the fuel solenoid.

Yep, oxidation/corrosion on the male spade is common on 300Tdi's so I don't know why it wouldn't happen with the 200 either.
Buff it up with Scotchbrite and away you go again.

With ign on and replacing and removing the solenoid wire I can hear it click as it pulls it in.I replaced it with a spare and no difference.
With the bleed on the filter open and turn it over plenty of fuel pumps out.
Same with the fuel in banjo to the IP . Undo that and fuel spurts out in time with the lift pump.
Took off the return pipe from the IP. Fuel comes out there when turning over as well, yet nothing from the injector pipes.
Still waiting for a mate to come and help me tow start it to see if that still works.

just because the solenoid is clicking doesnt mean that its pulling in.
and just because it clicks when you are statically applying power doesnt mean its getting power while cranking.

next step is to manually wire in a bypass from the battery to the IP solenoid and try to start it, if that works you are having ignition circuit issues.

if the bypass doesnt work remove the solenoid, remove the plunger and replace the solenoid. Slack off all the injector unions set max throttle and try for a start. If that doesnt get you fuel at the injectors then yes, most likely you have a problem in the IP.

I believe that one of the banjo bolts on the injector pump has a fine filter that can block - I think this applies to the 300Dti. Is it possible that the diesel is getting to the pump but not getting into the pump?

thats a 4bd1 thing. specifically its a strainer on the inlet banjo for the lift pump.

the equivelent for the (x)00tdi is the sedimentor and tank to sedimentor line filling with clad.

in this instance lift pump and line blockage/leaks have been ruled out with the lift pump shifting sufficient fuel to allow flow at the inlet of the IP and the IP returning fuel out of the return line union when cranking.

The issue should be related to the IP fuel solenoid by means of an electrical issue when cranking on the starter motor or because the nozzle is not retracting correctly when the pump is only making limited pressure at starter motor cranking speeds.

OK. Sounds logical. I will give that a go tomorrow.

Thats a relief. Put a wire direct to the solenoid and it started first kick
Sounds better than our daily drive.
Its a rats nest of wiring under the bonnet with alarm sirens and redundant spotties so I am pulling all that out. I guess there is a short or something in there. Might be the alarm controller but there are bare ends everywhere.

I get a bit irritated when people start a thread asking for advice, then dont finish the thread by telling the helpfull people the results.
In this case thanks to all and hopefully that info will be of use to someone else.
