Intermittent Starting...

Hi

Had to swerve sharply to avoid some clown that pulled out in front of me Monday.

Since then Landy (Defender 90 300 Tdi) has 'almost' not started 3 times

Engine turns over fine, fires and then immediately dies - bit like when starting a 2 stroke petrol strimmer on full choke!). Therefore presuming a fuel starvation issue?

First time was after it had sat overnight. Other times were after it had just been stopped a short while.

No loss of power once started which made me discount my first thought which was lift pump.

Have also checked stop solonoid wire but looks OK - gave it a good wriggle!

Am thinking:

- Sediment disturbed by swerving (either in tank or fuel filter)
- Fuel hose stretched by swerving now allowing air in
- Stop solonoid on way out
- Lift pump on way out


Would welcome thoughts on the most likely suspect/most sensible order to investigate

Any other potential causes?

Many thanks guys

Did you undo the priming bolt and operate the pump?

I did Dave - pump worked (although lever was very stiff), but the problem was getting worse when the Landy was left, and seemed to be proportionately harder to start the longer it was left - after a week it had to turn over several times before it would catch.

Couldn't see any fuel line leaks and fuel filter was good and tight, so suspicion was pump was on the way out and steadily getting worse.
