Thread: Series Diesel no go

I had the same problem with my fender,it would run fine then stop.Like you I changed everything a few times but at some point I knocked the wire to the cut-off switch on the injector pump.I pulled it off cleaned the connection and made sure it clicked when it went back on and it hasn't stopped since. Pat

AFAIK, there is no cut-off switch on the Series Diesels - all had an "Engine Stop" cable... which may be something to look at if the spring returning it is not broken and is moving freely (... I know I know... it was one of THOSE moments). Other than that the pickup pipe may be clogged up in the tank or fuel pump.

Nice idea PAT - unfortunately no wires here...

Alastair - what do you mean by "inline ryco filter" - you don't have a petrol fuel filter on a diesel do you?

Have you checked the ring of screws on the fuel (lift) pump are tight? Is the diaphragm OK? Could there be any crap in the tank blocking the pickup?

Are you bleeding both chambers of the pump? Where is the air when it cuts out?

OK only tdi owners look at the cut-off wire. Pat

G'day All, I had a similar problem about 20 years ago with my 2.25 diesel, the problem was in the lift pump, a faulty valve was allowing fuel to run back to the tank, it happened whilst driving and when parked up for any length of time, 2 new valves in the pump end of problem, that was my fix 20 years ago hope that's of some help cheers Dennis

I think Dennis is on the money - sounds like classic lift pump symptoms. I'd also be concerned about a ryco plastic in-line filter on a diesel (if thats what you're describing) - give that the flick before it gives you trouble.

Cheers.

Im with Dinty and IR on this one, if the diaphram screws are loose, it can suck air and not leak, and I have had the check valves fail on mechanical pumps before which can make the pump pump nothing or as Dinty said at rest allows it to flow back to the tank providing a void in the system.

Have a go at the pump and see what happens then.

By the way IR, I run a standard Z14 on all my machines at work and have never had any problems, why would that be a problem? They make my expensive fuel filters last a hell of a lot longer and a $3.00 a shot, I dont mind changing them every service.

the ring of screws around the lift pump (the bit I pump up and down to prime it) are all very tight...

now it won't start at all...

If I had diesel bug in the bottom of my CAV filter, (which I cleaned out), does that mean I have globs of diesel bug sitting in my tank (even though I put biocide in)??

maybe that's the culprit. Although...the inline ryco filter only has clean diesel in it. I can see it swishing around inside...
