hengti 2 Posted October 15, 2006 Hello Well, I think my long suffering engine may finally have had it I had the HG done at vast expense at about this kind of time last year and have noticed recently that it has been losing water. Yesterday, it started misfiring ever so slightly and developed into a serious lack of go - as if it were a cylinder down. I haven't had a look at it yet, but suspect the HG again (likely the end for the car if it is ...) Question is about compression testing. I've just changed the oil and want to try and avoid contaminating it with fuel if at all possible (still hoping it's something simple!). Is there a fuel pump relay or something that i can remove that'll prevent overfuelling as i crank the engine? if so, where is it? it's a phase 2 1.9. thanks Henry Share this post Link to post Share on other sites
Guest rick03054 Posted October 15, 2006 Take out the far right fuse from the fuse box. Share this post Link to post Share on other sites
sonofsam 5 Posted October 15, 2006 It may be fused in two places on the fuseboard, mine was. Share this post Link to post Share on other sites
hengti 2 Posted October 15, 2006 hmm - thanks i think i'll just take them all out in that case. the starter won't be fused - presume this won't cause any other problems - ?! Share this post Link to post Share on other sites
jackherer 543 Posted October 15, 2006 the only problem I can see with taking all the fuses out is remembering which ones go where when you put them back All 205s I've worked on have just one fuse for the fuel pump, the far right one. Take it out with the engine running and it will falter then cut out, leaving you sure you've got the right fuse.... Share this post Link to post Share on other sites
sonofsam 5 Posted October 15, 2006 If it is fused twice you should have a connector like below.Yellow wire 76a i beleive. Share this post Link to post Share on other sites
brianthemagical 1 Posted October 15, 2006 would removing the tachy relay have the same effect? Share this post Link to post Share on other sites
hengti 2 Posted October 15, 2006 cheers guys now can't get either of my two compression testers to work ... one's got a split rubber seal and t'other is one of these threaded ones which (obviously!! ) has the wrong thread size a trip to whoever's left open is in order fingers crossed! also picking up a copy of Autotrader ... lol Share this post Link to post Share on other sites
hengti 2 Posted October 15, 2006 i should be too embarassed to admit to the following ... compression tested at 175-170-170-180. that'll do for a 207k engine. then decided to fit a spare set of leads; ripped them all out and got to the dizzy cap ... where i spotted that one of the leads was already off... what. a. d*ck even after i'd thought it felt like it was running on three cylinders, i automatically assumed the worst (what with the HG thing and coolant loss) and went out and bought a copy of Autotrader ... damn this car! it refuses to die!! i'm putting all of this high melodrama down to the fact that i am in serious need of a holiday ... i'll probably have to be changing the oil and filter anyway, as i did about 20 miles in it yesterday on three cylinders ... feel free to laugh at me Share this post Link to post Share on other sites
