Thread: Fueling Problems

I've just got back from my holidays on three airbags and a fueling problem!

No issue on replacing the rear airbags, I've been needing an excuse to splurge out on Arnott Gen 3s and this is that moment.

The new issue is with the car's performance. Recently I re-built the fuel pump replacing it with a Holden equivalent and I also replaced the Crank Positioning Sensor. The car has been performing well over the last month until I got close to my holiday destination; some 200 Kms at a steady 100km/h, the car returned a good 12.3l/100km. Now the car is very slow to accelerate, has no power and misfires if pushed too hard. When the revs increase beyond 2500 rpm, suddenly the car clears and all is well. I've cleaned the MAF sensor, I'm not sure if there's a fuel filter, but I'm going to have a good hunt around for one.

The easy option would be to plug into a faultmate, but I don't have one (yet)! is there anyone close to Newport that I can borrow a faultmate to rent/trade/beer up?

(On the plus side the aircon is back working, the radio works, the fan relays have been changed and are blowing well, the O rings are in, secure and no more wet carpet, two blend motors are fixed and one more to go......)

Does this latest fueling issue sound a familiar misfire note to anyone?

Fuel filter is under the RR, inside rail of the chassis under the drivers door.
Silver can.
Use a drip tray/bucket under it and put something between you and the fitting when you undo it (rag plastic bag).
There is a lot of pressure in there.
Probably do it when the exhaust is cold as well.

I pulled the fuel pump and found crud on the filter, must be from when I refitted the pump after repairing it a couple of weeks back - 15 years of crud. I had a good look in the tank and it now seems clear.
I also changed the fuel filter (thanks Hoges). I took the old filter and blew my airline through it, what came out was black, gritty and lots of it! Obviously very dirty.
Went out for a drive and so far so good. I need to test her over the next week to make sure - wish me luck.
FWIW the Mercedes got the same treatment "ve hav ways of making you verk"
