went to my car dinner time, turned the key and no purr. man came out and says petrol pump has gone. no sound or movement when key turned on, sometimes you heard a short whirr but now nothing.tried squirting a bit of easy start through air feed to check if ignition ok and it fired. checked fuse 18 thats ok.
removed plate in boot and removed electrical plug from pump. there are 4 wires so i assume two are for the fuel gauge and two for the fuel pump, question 1 if i connect a test lamp to check power is getting there, should it come on when i turn the ignition on or does it rely on any thing elsewhere (any one know which wires are which) or question 2 is it best to remove the pump completely then connect to a power supply and last but not least question 3 how many types of pump are there as local motor factors says there are two. they gave me two numbers, x1093313 and x1093314. can any one shed any light on this please and thank you, these may be chassis numbers, one costs twice as much as the other but should be cheaper buying on the net
-
just checked, its not clear :(
they look like chassis numbers, however, I suspect the last 8 digits of your chassis number is S1xxxxxx
-
checked chassis number and is what you suggested. been researching on net and have found pump i want (vx part number 9120218, pump made by bosch) thanks. x1093314 relates to 94-99 omega, x1093313 up to 94.will take pump out and check by connecting to another battery before i order the new one....cheers michael

I had an intermittant starting problem that turned out to be the petrol pump sticking, it was the first thing I robbed off my HG failure donor car. saved me £150+ VAT on a pump
When I had mine out, I connected it up to a battery and confirmed that it was sticking as it would only work if it was given a tap. It worked really well the next day when I syphoned 60 litres out of the donor :)
Not that common a failure I believe, so you may get away with a second hand one from one that is being stripped!
Not had any problem with my replacement.
-
I assume the fuel pump relay has been ruled out......and that there is no code 19 stored in the ecu?
-
if you need a pump let me know have a spare for sale :y
-
took the pump out ,connected it up to spare batteryand away it went. no power at connector in boot so where do i find the pump relay as suggested and can i swap it with another one just to check it
-
Checked the Tech Info forum and found this...

hope this helps.
(but would also suggest changing the fuse, or circuit testing it, not simply pulling it and just giving it a visual....)
-
many thanks for the info. will treat myself to a circuit tester tomorrow.swapped the two violet relays over but still no power in boot connector so it could be the circuit which fuse 18 protects. im getting withdrawal symptoms now , some how my mates nissan micra aint just the same but at least it gets us to work.
-
Don't need a circuit tester. Get a battery out a smoke detector and a bulb out of a household torch of compatible (9 volt) value. Short the bulb over the battery terminals to ensure it works. Then guddle with the fuse, the bulb and the battery to ensure a complete circuit. If the lamp lights, fuse is OK. If not, try another fuse..... :y

Whats a "guddle" ;)
-
'Guddle' is a fine Scots word, the essence of which means to play with, fiddle around, be in a mess with or similar. In the context given, try to link all three items together into an electrical circuit by use of only two hands.........
If you do not guddle correctly, you could end up in a right guddle, as it were..... :D
-
well i had a good guddle ;D. borowed a circuit tester from work and there is no power in the circuit. daughters boyfriend burt(not his real name) suggested that it could be an emergency fuel cut off switch. are they fitted to an omega?and if so where?

And there was me thinking you made these expressions up as you go along. ;D

Don't think they are fitted mate, but I could be wrong.
-
when i turn the ignition on should the orange light with the engine symbol on it come on and then go out when it starts
-
yup
-
oh dear, mine doesnt :( any ideas on this
-
Doesn't what, come on or go out?
-
it doesnt come on
-
Duff bulb would be my guess.
-
Possibly previous owner removed it to cover a fault..... :-X
-
and i bet this is the bulb that flashes on the paperclip test.what about these code readers you can get, a tech 2 reader, are they any good (seen on ebay)
-
im sure it used to come on
-
The El cheapo tech2 only works from -97 and on, so it probably won't work on your car. Just take out the instrument panel and replace the bulb. Replace all others bulbs there while you have it off.
-
lets go back a few posts to the suggestion of code 19 stored on ecu. how does this affect the petrol pump as i cant here it when i turn on the ignition, there was once a small whirring till the pressure built up. how do i rectify code 19. trouble is i dont want to make the vauxhall garage any richer
-
any idea where i can get a proper reader? going to have a beer now :) and call it a day, will check bulbs tomorrow.
-

awsome tool
-
1) Sort the bulb....
2) Do the paper clip test to see what codes are stored.
For info, code 19 relates to crank sensor, if no crank signal is seen then you get no spark or injection operation.
And the cheap tech 2 will wpork on all the Omega cable throttle V6 power plants from 1994 onwards.
-
thanks, gonna have breakfast then gonna get on with it :y
-
To fix the bulb, pop the instrument panel out.
Its pretty easy and there is info in the maintenance section telling you how to.
-
popped the panel out and there was 5 bulbs missing and one was the engine management bulb so i popped out on the old bike and got 4 bulbs cos thats all they had. tell ya something my bike seats not as comfy as the omega seat, lol ;D,having a brew then gonna put it back together again and do the paper clip test.must remember to take the butter knives back in or my good lady not be happy :(
-
did paper clip test and not good :(
1, alarm 144
2, alarm145
3, alarm135
4, alarm69
5, alarm31
had a new key done sunday which is chipped and i bet thats naffed up the immobiliser(144 and 145). can this be sorted by myself or not, i have 4 digit security code number.
-
What do the lights do when you try to start the car. If they are flashing that is an immobiliser signal and the car won't start till that's sorted, the engine ECU will stop the ignition and injection till the immobiliser ECU is happy hence no sound of fuel pump working.
-
no flashing lights at all. i have a remote fob which has a large button in the middle and one the side which looks like its for the light .have never used it and think batterys are flat. is this for the immobiliser or the alarm.
-
Not 100% certain on the older setup which yours is. The later key has a built in fob which opens doors and disables alarm. There is a chip in the key which talks to the immobiliser sensor around the ignition barrel and if all is ok then the ECU gets the ok to start signal.
As I say I've never had one of the alarm fobs but on the two button key one button unlocks and the other locks on the first press and deadlocks on the second.
-
Aha.....infra red immobiliser setup......you have PM
-
where is the immobiliser alarm/unit situated and whats the best way of getting to it. read somewhere on my journeys around the web that it could be a soldered joint which has burnt out.a quick visual could confirm this
-
any one know if torx do a t26 star driver as 25 too small and 27 too big or is vx done this to stop us having a guddle(see previous posts for scottish translation)this is for thesrews in thre top of the glove box
-
the neighbours got one
-
how do you clear alarms stored on ecu
-
where does the crank sensor plug in so i can check the connector as not sure which type it is
-
back on the road again. had all keys reprogrammed and also had new crank sensor and other sensor wasnt fitted properly. runs a lot better, sorted now .thanks for all your advice.
