Started with slight misfire quickly becoming intermittent throttle response.

Then no throttle response and idling very rough. Then cut out. Turns over and fires but cuts out after 10 seconds or so $:-\$

Half tank of fuel, just put £30 to be sure, as felt like running out even though gauge was just under a quarter. Waiting for AA, but pedal trick shows a bucket load of misfire codes and a couple of cat codes.

Car is due service/cambelt, but taking some comfort in the fact that it turns over, been quite tappetty the last few days though $:-\$

Plug wells, duff coil pack?

05omegav6 · « **Reply #2 on:** 31 March 2013, 22:53:50 »

All bone dry, nothing to indicate a dodgy coil pack, went from running perfectly to broken in about ten minutes $:-\$

Jimbob · « **Reply #3 on:** 31 March 2013, 22:55:23 »

what were the codes? for one bank or 2? Anything MAF related? does unplugging the MAF make any difference?

Crank shaft sensor? $:-\$ $:-\$

symes · « **Reply #5 on:** 31 March 2013, 22:56:39 »

maf/dbw throttle body

or crank sensor

tunnie · « **Reply #6 on:** 31 March 2013, 22:56:47 »

Checked plugs? I blew the electrode on one once, ran fine and in an instant changed to bag of spanners

Just read youve washed it....Is the air filter dry?

05omegav6 · « **Reply #8 on:** 31 March 2013, 23:05:29 »

Maf unplugged no difference, filter dry, pipe from air filter dry and no different if removed. Codes 0420,0430, several 0300, 1 0305? And 0115. Car starts so not convinced about crank sensor $:-\$

Have you peered at the cambelt yet? guess not? hoping youve not jumped teeth

Jimbob · « **Reply #10 on:** 31 March 2013, 23:09:27 »

So code wise, ignoring the old precat codes, we have a cylinder 5 miss, and a coolant temp code...

Wonder if it thinks your too hot / cold and is fueling to match?

Jimbob · « **Reply #11 on:** 31 March 2013, 23:09:54 »

have you a 'live data' capable code reader?

i do, well, someone elses.

Fuel pump perhaps? $:-\$

0115 is an odd one though.

05omegav6 · « **Reply #15 on:** 01 April 2013, 00:13:08 »

Supersized onion bhaji goes to Mr Wood

Coolant temp not big surprise given thermostat stuck open, but culprit is the fuel pump... 120k from a pattern one $:-\$

05omegav6 · « **Reply #16 on:** 01 April 2013, 00:18:20 »

Thanks for the input

Shall whip the pump out of the other one for now, but that's definitely the last time I wash my car during a bank holiday weekend

Remove fuel pump fuse and (or) relay. Wait 1 hour. Instead of waiting you can release fuel pressure by pushing valve stem.
Try to start engine. Listen if it turns evenly. If some cylinder is "missing", belt is possibly broken, valves are bent.

Whilst cranking car, whack base of tank with a heavy object, fires instantly and runs fine, nice and smooth, pulls as expected

dbug · « **Reply #19 on:** 01 April 2013, 00:52:34 »

Yep its knowing where to hit it

About eighteen inches to the right of the towbar and as far under as you can get your foot whilst standing

Not too bad then.

Bahji bill paid on weds.

05omegav6 · « **Reply #22 on:** 01 April 2013, 14:08:15 »

Dats dat done

A couple of points worth noting...

1. the pump filter was in two pieces.
2. evidence of tiny metal particles in the filter and the tank itself. So guessing the pump had lunched itself trying to draw fuel past the lower half of the filter $:-\$ a bit like trying to drink through a straw with an ice cube stuck to it...

Any mileage in fitting an uprated pump? And any ideas where one might find one $:-\$ presumably need a higher pressure valve on the fuel rail to match it $:-\$

Given that Omega fuel pumps are bulletproof with reported failures on here not exceeeding the number of fingers on one hand, standard is fine and second hand is low risk (and clearly lower than pattern!

)

Hmmm $:-\$ must be a plod thing... two out of two having had new pumps fitted at some point.

Still even a VX pump is still significantly cheaper than a VW diesel injector
