200tdi fuel line help

I tried to start the engine today, no go. Fuel is just not getting to the injectors.

A couple of questions.

Which side of the lift pump is intake? which side is out?

Does the line-in from the fuel tank go to the rear(closer to the bulkhead) of the lift pump or the fitting on the front(closer to the Rad)?

I'm going with the assumption that of the 2 fitting on my 1985 style side fuel tank, the out to lift pump is in the center of the sender, and the return is the other. But we all know about assumptions.

Engine ran great out of the truck about a month ago.

Thanks

fuel goes in on the front fitting and up to the filter from the rear one. Slowly turn the engine over untill the lift pump is on the cam lobe @ that point you should be able to use the little primer lever on the underside of the lift pump to pull fuel up from the tank and up through the filterhead where the bleed screw is. I had a hell of a time with this on my 110 and I had removed a diesel engine (lines were already full of diesel).


Your assumptions on the return and feed lines is correct.

That the bleed screw on the fuel filter itself?

that looks like the universal replacement pump George is selling- works on both 200's and 300's. The finger lever has no resistance when the pumps actuator rod isn't on the cam lobe- if you have someone slowly turn the engine over with a socket you will feel what I am talking about.


The bleed screw is a banjo bolt on top of the Tdi fuel filter housing -not the water drain @ the bottom of the filter itself.

Crack the injector lines.

Turn over until they leak.

Tighten one, crank, then the next.

You should not need to bleed as the system is designed to be self bleeding.

Wouldn't cracking the injectors be bleeding them?
After cracking them, which do I tighten first?

The pump does not need to be bled. Sometimes, though, when the injectors are dry, the pump has problems pumping the air out of them.

It does not matter which, you are just getting the air out of the injector lines. Once one is tightened, it will probably run. It faster to do all of this than the time it takes to type this message.

We might want to back up first. Is there power to the fuel solenoid? Can you hear it click on and off?

Just what i was going to say.... turn the ignition "on" and pull the spade terminal off of the pump, see if you can hear it click.
