So rulled out fuel cut out switch? Out of interest have you wired up the old pump externally to see if it works ok? So after an ECU reset it starts for a few seconds then dies and won't start again until another ECU reset. Could it be it's primeing, starting and using the primed fuel in the rail, then stopping once it's used the fuel in the rail? So for some reason the pump primes but doesn't continue to run when started? What tells the pump to start running when engine is running, ECU? Scangauge not connecting could point to failing ECU? I'm pretty sure there's no "pressure sensor" for the fuel, pump just runs when engine is started and excess fuel comes back into the tank. Hopfeully the Oracle that is Vocky will come and confirm/deny/add to what I've said.

I tested old pump before discarding. Scan Gauge worked once I got the car started. So I just checked with Scan Gauge and got code P1612 loss of IPM serial Data. Searching here seems to indicate an immobiliser problem - so I guess I am going to follow these tests first before I go replacing immobiliser.

Hi All I'm having a similar situation, just pulled the VXT out after 6months of hibernation and she won't start. Turns over fine but won't fire. Im suspecting the fuel pump as it doesn't sound like its priming when I turn the ignition on. To confirm its a fuelling problem I've tried a dribble of fuel on each plug and it fires ok (just for a split second or so). Whats the best route to start testing things? Should the relays be the first port of call before 'presuming' its the fuel pump, they are in the boot somewhere I believe? Anything else I can look out for/test? Thanks in advance!! Mike

Just another thing to check, I was having similar problems and it turned out to be the plug that plugs into the top of the fuel pump/sender/tank. The pins inside the plug had spread and were not making good contact. It would prime, start then cut out. Pushed the 4 pins back in so they made a good connection using the tiniest screwdriver every and the problems went away. Good luck :) Deano

It's either T45 or T50. Pretty sure it's T50.

Hi Guys,

 

I bought a 255l/h pump from Courtenay and am fitting it following this guide.  It's very difficult to get the convulated pipe on it, had to order some spare ones that will arrive in a few days.

 

Do i just have to slide the pump in the housing or do I have to cut something away or secure the pump, the original pump stays in its place with the fuel filter (so it doesn't drop).  But the walbro pump has a filter with 

 

a spring inside and can slide down since it isn't attached to the housing.  Should i just let it rest on it's spring?  Hope you understand what I mean.

 

Thanks in advance for any responses.

 

Fre

yes, the fuel pump just slides into the housing.

 

You should use the original hose and trim it from the old pump, retaining as much of the original hose as possible, then use a fuel clip to secure the original hose to the new fuel pump. Bin the new hose, it really doesn't fit.

Has anyone else struggled with the big blue seal to get the assembly back into the fuel tank? It went in really easy but it turned out the seal had just dropped into the tank. It seems to be a little too large to fit properly.

Give it a good twist It shouldn't fall of but if it was twisted it tends to fall down, What I'm trying to say is make sure it's not twisted 🙈

Gave up and bought a new one. Fitted in really easily. Now I've had the pump out AGAIN and this one has swollen too! No amount of twisting and shoving is getting it in.

you need a new blue seal everytime (with the PA tank, easier with the std one) and i put it in the freezer over night first which helps a lot.
