Hi, Well I got the pump sorted!! It had been running on Bio-fuel ( Fish and chip oil ) and the inners of the pump were like the bottom of a chip pan that had been using the same oil for years... It has been rebuilt and bench tested by an expert, at least I now know what I have.

I looked and yes the pump seems to have had a complete rebuild, I have left it in with a guy who is going to put it on the test bench next week, he thinks the return from the pump has to large a pin hole and therefore not building pressure up in the pump. I'll let you know the outcome..

Yea it does suck.....I wish it just pumped!!! I'll not give up yet... I walked past the pump a few times today and threatened to pull it apart........ I live in the North of Ireland. Plenty of pump re-con shops around but at a price...... I always approach problems as tho I was in the middle of...

I bought the pump on ebay, the chap I bought it from is a breaker and to his understanding it had been recently been rebuilt. It does have yellow paint on the adjusting screws and has a anti-tamper wired screw with paint, it does look as though it has had a re-con. Low housing pressure sounds...

She gives a wee puff of suit when firing up from cold and then is clean whilst idling, It's no where close to a steady flow... the odd drip! Yes, it sounds like a fuel shortage, I just don't know how to fix this one! Ie; the pump being a tad completed....... I wonder is it a common problem?

This engine is sitting on a pallet on the floor, so I have a lead from the battery direct to the shut of valve and its working fine, she ticks over beautifully and will rev a few hundred revs more, but that's it! its as tho she just isn't getting enough fuel! Strange thing is their is very...

Well I checked all of the above, the pump timing is spot on, and the firing order also, it has to be the pump! I can't see an air lock being the problem but that is next on the list to try and cancel out, along with pressure etc.

Thanks for that... The timing can't be to far out as the keyed shaft of the pump fits through a gear that is driven from the crank gear, a toothed pulley is then bolted unto the driven assembly that has a dowel pin. The cam is then driven via a timing belt from the pump. I was wondering would it...

I followed advice from a thread on a site of a chap who had done the job, his advice was extend the slotted mounting holes by 1/4" and the timing would be spot on, that's what I did and when rotating pump a few deg adv/retard, she run's rougher. so I am taking the 7# number from his blog as I...

Thanks for the reply..... Timing is good 7* ATDC, firing order is good, I put a pump on pre injector pump to pre-load/ add pressure in-case of air lock, No difference! I spoke to the guy I bought the pump of and he said the pump was good and had a full re-con pre my buying it on ebay. I'ts got...

I have just fitted a 2.8 4M40 pump on my 3ltr 1KZ engine, she started first time on the garage floor, but sadly just ticks over and reves little more! can anyone shine some light on this please? Ps; I am intending to fit the lump into my boat if I can get it sorted........ I've been driving a...
