Spending time and money on a problem when it wasn't what you thought! - 306Puggy - 25-11-2012 I am going to share this tale of trying to fault diagnose a problem and completely wasting their money on it! Basically, I rebuilt my fuel pump and then the engine started playing up. The story goes like this (the abridged version): April 2012 My car was fine, boost pressure 22psi, generally healthy, just gone for the MOT. Comes back, fails due to weak handbrake, split CV gaiters and fuel leak. Fixed the handbrake and gaitors. Fixed the fuel pump with new seals, chuck it on, starts playing up. Won't idle at normal speed, keeps cutting out, smokes a lot. It was a coincidence that it started playing up after I'd rebuilt the pump (as I would later find out). April-August Working on diagnosing the problem. The following work was undertaken: retension timing belt twice adjust throttle arm about a dozen times or more adjust max fuel screw rebuilt pump several times adjusting governor shaft (the one with the jam nut) bleed the fuel system running the stop solenoid without the spring so it is always open adjusted idle screw replaced inlet/outlet banjos checked timing (multiple times) tried pump at full advance and full retard pulled pump injection ports, cleaned and replaced replaced fuel pump new timing belt checked valve clearences replaced fuel lines with clear jobbies replaced pump pulley stripped and cleaned injectors replaced manifolds gasket posted problem on numerous forums There were large gaps between these jobs and a lot of jobs I did many times over to make sure I'd done them, due to being at uni most of the time. As you can see from the list, a lot of the jobs where just speculative fixes; i.e. I was clutching at straws for what would cure the problems. This was because I had rebuilt the pump several times and was certain it was right so I started looking into other things. Every obscure possibility was looked into that I could think of. October 2012 Post on this amazing website, several posters suggest it could be a blocked fuel filter (including the man who would later fix it). I am skeptical because of two main things 1. How would the fuel filter being blocked cause a missfire? and 2. I had run it off a bottle of veg and it was still playing up. Here is a video of how it was running: You could see why I thought it was something to do with the pump, not something as simple as a fuel filter. November 2012 Finally manage to get it to KrisB, he looks at it for a minute and diagnoses the fuel filter right there and on the spot. After a new fuel filter and some injection timing adjustment, it is back and as good as new. And, being the legend that he is, only charged a few quid for it! So, let's sum up how much I spent, from the top (not including hours of labour and fuel drenched hands): Pump Seal Kit £15 pounds Cambelt £16 pounds Fuel (for test running engine) I estimate about £20 pounds Several new tools £20 pounds New Bosch pump £50 pounds Valve feeler gauges £6 pounds Clear fuel lines £5 pounds New injector washers £5 pounds Manifold gasket £8 pounds So, all together that is £145 pounds for the sake of a fuel filter which costs about a fiver. Sometimes it is better to take the car to the mechanic, eh?I would have taken it to KrisB's earlier but I didn't think it would drive with the way it was running. God knows I've left some stuff out because I've forgotten about it, but what I have listed is the bulk of the work done/money spent.

But yes I know what you mean, I also often spend lots of money to find out its something simple broken.... RE: Spending time and money on a problem when it wasn't what you thought! - Mattcheese31 - 25-11-2012 should've just changed the fuel filter . .it's a no brainer when you've had these engines for a while . . RE: Spending time and money on a problem when it wasn't what you thought! - Dave - 25-11-2012 The fuel filter was suggested many times in other thread RE: Spending time and money on a problem when it wasn't what you thought! - Dum-Dum - 25-11-2012 And this is why you should keep your 306 well serviced with new filters every 6k on an XUD. RE: Spending time and money on a problem when it wasn't what you thought! - 306Puggy - 25-11-2012 Heh, the funny thing is I hadn't done that many miles so I didn't think it was the fuel filter. Plus it was reasonable to suspect the pump since I had recently rebuilt it. I've only had the new filter in for a few hundred miles and it's already showing signs of playing up again! RE: Spending time and money on a problem when it wasn't what you thought! - Dave - 25-11-2012 You should listen to good advice given to you on here by many people.

RE: Spending time and money on a problem when it wasn't what you thought! - Dum-Dum - 25-11-2012 If your running on veg and a tuned car youll clog them pretty quickly. Do them as often as you need till it stops clogging RE: Spending time and money on a problem when it wasn't what you thought! - procta - 25-11-2012 thats what you call sods law, the most easiest thing can raise hell!

If you regularly run it low then you will pick up the sediment from the bottom of the tank and clog the filter up RE: Spending time and money on a problem when it wasn't what you thought! - 306Puggy - 27-11-2012 Yeah you are right Swampy I only ever fill up five or ten litres at a time which is why it scoops the crap up I guess. |
