Day 3 of 4 (originally 7) – heading to the South East (ish) with some stops along the way and our last away trip of the year…
We left our fab digs in Little Thetford and headed down to Royston, where it was lovely to meet Jonathan who asked if we could come and investigate an issue he’d been experiencing with his 2001 MGF mpi 120 (in paint code JBH).
On idle the car was massively hunting flicking between 500 and 1500 rpm. Part of the problem was a faulty Lambda sensor, the other part of the problem was that someone had been adjusting the throttle body stop, this usually has a small cap on it and should not really be messed with.
We replaced the Lambda sensor and as he had a new aluminum 48 mm throttle body we fitted this too, and problem happily resolved for Jonathan, and no other error codes coming up.
From there we headed over to Biggleswade to take a look at what was occurring with Barry’s 2004 TF 135 (in paint code HFF).
Some time ago he had experienced a loss of power with the car, and after that it wouldn’t start at all. He’d had two new fuel pumps fitted, fuel filter, plugs etc etc all to no avail.
Unfortunately, we hadn’t been able to get down to see him before today. So we set about with our usual investigations, such as checking the ECU for codes, nothing really relevant found, the crank sensor and cam sensors were fine, so after testing the fuel pressure and finding that there was absolutely none, we set about trying to remote power the fuel pump, while we could hear it working there was no actual output from the fuel pump. We decided to remove this from the fuel tank to see if a pipe had come off, as it was though to be reasonably new, however once we removed the cap off the top the sender-unit it was found that the seal that was meant to be around the lip had dropped into the tank when it had been fitted, when trying to remove the complete
sender-unit it was actually in pieces and with some of the parts missing!
As it was so badly damaged we had to dismantle the rest of it while it was in the tank as it wouldn’t come away in the usual fashion.
Once all the bits were finally removed from the tank the fuel was direct wired and found to be faulty yet again.
The whole sender unit and pump housing will have to be replaced, as well as the pump. Once this is all done we will get on with the other main issue of finding the reason for the pump wiring not being powered.
Poor Barry, not only is he very poorly, having just come out of hospital he also has a very poorly car. Pump duly ordered, we have a couple of sender units on stock so a date to be arranged to get this sorted for him. Hoping Barry makes a full and speedy recovery and that we get the car fixed soon too, feeling a bit sad for Barry right now. It was great to meet him and Lucy though and have a chat before we headed off on our way. We look forward to seeing them again soon!
Now wending our way round the M25, through the Dartford tunnel and on to our next destination for the night.
Good to have such decent weather again, too. – https://ift.tt/365IZ9x
