Hello,
I have got a Peugeot 406 2.1TD with the EPIC pump. It's recently started cutting out when up to temperature, particularly when returning to idle (e.g. at junctions). I'm suspecting it is something to do with the pump or pump electronics, but I was wondering if there is anything else to rule out.
I recently replaced the fuel pipe all the way from the tank to the filter as I had noticed a few small air bubbles in the pipe from filter to pump. I know these pumps are sensitive to air. There is no longer air in the clear pipe from filter to pump. This didn't help solve the cutting out.
Symptoms:
- Runs fine cold and warming up, it's just when it gets up to temperature that it cuts out. Starts fine when cold too.
- The first time it cut out it restarted normally but I was pretty much home by this point so it was only driven for less than a minute after restarting
- The next day it cut out and when restarting it would run for only a couple of seconds before cutting out, but would rev a lot by itself in those couple of seconds. However, the rev counter stays at zero and other lights stay on on the dash, so it's like the car hasn't recognised it is running in those couple of seconds. It sounds awfully clattery in those couple of seconds, like the pump is going way too advanced.
- The only way I could get it to stay running after restarting several times was to have my foot slightly on the accelerator to hold the revs. After a short while of sounding awful, it would then run normally, but then when getting to the next junction and returning to idle it cut out again. If I keep my foot slightly on the accelerator at a junction then I can keep it running.
- For a few years now, when turning off the key, the engine carries on running for a few seconds, which I haven't addressed as it didn't really bother me.
Do these symptoms point to something in particular, or is there anything else I should do to rule anything out?
Thank you.
