Evening all,
Took the car out yesterday evening, mainly to fill with fuel as light was on a week ago on way home from work. Been stood for the week.
Started fine, drove fine to petrol station (only £20 as only 97 at local garage) then driving home car spluttered then stopped. Did turn over fast enough and a slow ticking sound from drivers rear. Wouldn't start though.
Towed home.
I put battery on charge overnight as hazards and lights on for an hour. Today the engine turns over quickly and almost fires a couple of times. Still clicks, just under once a second.
I'm thinking Fuel pump/relay/DME or CPS?

Any thoughts?

Cheers
Ed

Im going to have to start with the stupid obvious questions .. sorry ..

You did put petrol and not deisel in the car ?

Bad batch of fuel .. but normally many other cars would be at the side of the road and yes ive seen it before .. cost the petrol station a fair bit .

Ok moveing on from that to an unrelated fault .. car trying to start and you have CPS ok .. you have a poor fuel delivery or a poor spark .. individual coils almost rules out spark so fuel pressure ..

pump being the main one .. pump relay and you would have NO fuel .

If i was going for the horror story .. Ims bearing has let go .. this normally causes a large oil leak and noises when cranking so a little unlikely from the description .

Thanks DeMort,
Definitely put petrol in.
No oil leak.
If I turn ignition on from cold, I can't hear the pump pressurising the system, so I'm thinking fuel pump. Any DIY way of checking?
The clicking sound is regular when turning over, IMS would be irregular?
Thanks fella

IMS is an outside chance but one i have to mention .. you would have plenty of strange noises as the chain timing would have slipped so i think this is unlikely .

Because its trying to start then things like CPS , Cam sensor etc can pretty much be ruled out .. if it Didnt try and start then ok .

Fuel pressure is the most obvious atm but bridging the pump relay wont really tell you anything .. you need a pressure gauge on it as a Low pressure ie a knackered pump would do this sort of thing .

You wont hear the pump running .

To be fair there are a few things that could also cause it and really to procede you would at least need a fault code read out ... if you have a tester then do this please as even the lack of a code helps .. (its fuel pump btw if no codes )

Only diy atm i can think of .. just check the fuses .. look at the handbook and check things like engine sensors , dme etc .

I dont like coincidences though .. you filled it up with fuel then this happens Question

Stupid thought .. unplug the maf sensor and try to start it .. clutching at straws a bit but its worth a check .

Ed /911 AU, if you haven`t got a code reader or access to one, then buy a £3 ELM 327 bluetooth OBD dongle from fleabay and download the free "Torque" app on Android or iphone and you will have a very good ECU code reader, EML reset tool for next to nothing Thumb
