Thanks again Chris!

I'll see if there's any fuel getting through tomorrow-I'll take a pipe off in the engine bay. If there is, I'll assume a problem with the ECU block firing the injectors.

Regards

Yeah .sorry i misread your post. You said you had power to the pump. Yes if you remove return hose to tank you should get fuel when pump is powered up. When cranking or try in cranking position but with small starter spade pulled off.( allows you to test pump with aid of an assistant but not unnesesary flattening of battery / unnesseary cranking. ) then once you have confirmed fuel ,confirm spark again. Confirm live to one terminal of any injector plug.injectors will only fire when ecu gets a signal from distributor neg side so check green wires are all sound.also if yours is an early type there is a resistor block in series with all the injectors .make sure relay is ok and connected properly. Haynes book shows this and any associated wire colours.

Thanks Chris.
That's a good idea removing the trigger to the starter!

Weather permitting I'll have a go tomorrow.
Senator and Royale totally different.

Senator smooth, quiet and comfortable.

Royale very quick (even by modern standards)-but noisier and less comfortable.

Had a quick fiddle after work-took a fuel pipe off in the engine bay and no fuel when cranking-so sounds like the pump (new one on 18months ago and filter).

Will investigate further when I get a little more time and it's not raining.

Will see if there's any petrol at the tank outlet as well.

Cheapy pattern pumps don't last too long... also, check the pipe hasn't dropped of the cover plate if an internal pump

[BazaJT]

I can't remember if the pump is in tank or external on these[it's been many years since I was last under one]but if it's an external pump have you tried giving it a tap with a hammer while someone cranks the starter to see if this "jolts"it into life?

[cam.in.head]

external pump. just sits on a bracket underneath the car above rear axle. the pump type is common to most injected vauxhalls of that era.carltons,manta,cavalier mk2 and 3 so should be plenty available.     steve.have you tried powering the pump directly to eliminate the pump or a live or neg fault.?

Thanks all,
Grifter that would be great-but I'm a little way from you! What colour was yours?


Steve

Hi Steve

Sure if you want them just give me a shout. Mine's was the same colour as yours. Not sure of the exact name of the colour though.

Blue.

Smartarse.

Lol fell into the trap!

[Steve Brookman]

Thanks all!
Did put a new one on about 12  Months ago-will check for power at the pump-there is power on the main feed when cranking. I'll jack it up and put on axle stands and get under Friday night or the weekend-I can get under-but y belly gets in the way! I've got a spare pump I bought a while back-it's a "generic" one-slightly smaller but same pressure-I'll also order another Delphi.

Will also have a look to see if there is petrol actually coming out of the tank.

Will also give it a bang!

Thanks again

Steve

yes report back after weekend with your findings. the pumps on these are easy to hear running so if yours appears not to then idealy it will be a loose wire on the pump or a corroded earth. especially if you have confirmed a live from the relay end. to be honest the original bosch pumps on these are generally reliable but obviously anything can fail. nothing lasts forever.from looking at pictures the delphi and other aftermarket pumps do look very very similar to the bosch originals. not compared any side to side or internally though just to see what differences if any ?

[Steve Brookman]

Thanks Chris,

Update, Had a bit of time last night and dropped the pump and filter.

Pump is not working.

Should have a new (Delphi)  one in on Monday  so will whip it back on and see.

One thing I did notice was the orientation of the pump and filter and fuel flow.

On this car the pump is first followed by the filter-wouldn't it make more sense filter then pump.

I think that's the correct way

Tank pick up should have a coarse filter on it, and the pump pushes the relatively clean fuel through the filter...

[Steve Brookman]

Yes it is strange-had a look under my Senator and that's the same.

A full-on fuel filter will be too restrictive for the pump to suck through, so it's normal to locate it after the pump. There should be a gauze either in the tank or in the pump inlet. Since you've had a pump fail relatively quickly, it might be worth double checking that it's getting a clean fuel supply.

Can also post-mortem the old one and see if the internals are badly scored.

[Steve Brookman]

will  do!
