before I swap out the fuel pump...

[legendgamesmaster]

Right then,

Before I go ahead and shell out on a new fuel pump (nifty nev, your aussie site has proved worth its weight in gold...) are there any easy options I should look at? Are there any electrical reasons why a pump might not work well, that can be addressed easily? since I dont know how they work apart from, er, pumping, I dont really know what I am looking for...

Obviously I will check all electrical connections are A-OK first, but then its crunch time.

Been quoted £180 plus vat for the pump Nevs lot suggest buying, and I am going to supply my VIN numbers to see if the 'correct' pump is any more expensive.

Toying with the idea of replacing the injectors too.... Ah feck, in fer a penny, in fer a pound....!

I read somewhere that at mitsubishi or isuzu fuel pump could be used with a couple of mods and will give the 2.4 a S$%t load more power

DOH! J4MIE......! do NOT provide that kind of enticement without any backup info.....

another power mod... want one.... you are EVIL!!!!

go and find out more details and report back, pronto.

Whats wrong?

is it as smokey as a smokey thing that has just been made professor of smokey things at smokeyfield university

The missus 2.4 is "a tad" smokey when setting off and at high revs, but passed the last mot (just), swopping the injectors made no differance & all the pipes and valves are in the right place.

I got a 2nd hand pump off flea bay, but my truck didn't like it, wouldn't rev and loads and loads of 1/2 burnt diesel fumes! put the old pump back on and it was perfect

Whats wrong?... WHATS WRONG????

MY TRUCK IS BROKE, THATS WHATS WRONG!!

and it seems to be the fuel pump.

my other threads explain the issue, but briefly:

ran fine.
stop engine.
won't re-start - just turns over and over - no smoke no catch.
wait 20 mins, restarts perfectly.

then a couple of days ago, just cut out while running.
now cuts out after warming up.

took to garage, they looked and suggest a 'fuel issue'.

Its not the filter (replaced with new) although I suspect the primer may need replacing. they tried it bypassing the primer/filter. still no good.

checked for fuel at injectors and the output was very low pressure dribble rather than the higher pressure I was expecting.

(its just like Razorhoofs problem too by the sound of it)

new pump is 200 squid or there abouts. 150k on the clock, part KM part miles, so dunno the exact amount of work the engine has done.

running on biofuel, so it could be the seals on the pump rather than the pump, so I am going to take the pump out and overhaul it. If I fcuk it up, I will buy a new one.

how did you find the job or replacing hte pump? Guess you are a dab hand having done it twice now! Any advice??

[BUSHWHACKER]

Have you tried running the engine without the fuel filler cap on? Could be a vacuum in the tank caused by a blocked breather tube, preventing proper fuel delivery.
Cheaper fix than a pump repair/replacement.

[legendgamesmaster]

ok, that was the first thought as it happened years ago to an old ford i had. there was a vacuum, but i have drilled a small breather hole in the cap now.
all the symptoms are of fuel not getting into the cylinders when the engine / pump is hot.
the possibility is bio fuel has degraded the seals on the pump and when hot / expanded the pump is sucking air / not pressurising.

thanks for your advice, though, its appreciated

[plumb bob]

If the seals were degraded, then it would leak like a sieve.

If the seals were degraded, then it would leak like a sieve.

thats what I thought, but the mechanic said to try it in case it was sucking air in. As it happens, my mate had that problem with a bosch pump in his escort van, so I didnt really think about it.

HOWEVER...

see my last post:

for a more likely cause...

[plumb bob]

That'll be the fuel cut-off solenoid, it's possible that's the problem, but I think it's a pump out job to replace it.

Check your previous posts for Nes comments on timing etc.

Calm down dear!

Yes i found it a complete b@stard!

strip off the front of the engine as if doing a timing belt, time the engine up and then remove the nut holding the pump, on mine it was very, very tight and took some serious persuasion with an air gun to get it to come off.

then remove the timing belt and the pump pulley. Remove the two water hoses to the inlet manifold for access, remove the air filter box (makes it easier to get in, remove the wires to the 2 water sensors on the thermostat housing and the 4 wires to the pump, remove both pipes and plug the ends & the leak off pipe, remove no 1 & 2 injector pipes completely, no's 3 & 4 will just disconnect and move out of the way, then you can get to the pump nuts, 2 are on the flange that mounts the pump to the engine, the back one will need a 3/8 ratchet and extension (I used a 12" one). then there are 2 more bolts at the back, you can just access them from the back of the pump, by the outlet pipes.

Once all that is done you can wiggle the pump out (and it takes some jiggling!!)

when refitting the pump don't make the same mistake as me and short the glowplug under the inlet manifold on the no 1 fuel pipe!!

nifty nev's site has some decent stuff on it http://www.toyotasurf.asn.au/techsite/

there is good instruction on how to remove the timing belt and pump.



...... good luck!!

This chap is breaking three 2.4s in Ledbury. Andy, might be worth giving him a shout for a cheap fuel pump.
