STiG Posted February 19, 2012 Report Share Posted February 19, 2012 After all the kerfuffle with Jess this week and getting down about the fact she wouldn't start, I had a cracking day yesterday with a ride in Nick's Evo... As such I am now haveing an Evo abuse amnesty for a few days!It turns out I missed a message on facebook from the previous owner telling me that the pump fitted was a walbro 255 so knowing that I had no problems until I fitted the RCM pump and after words of wisdom from many including Mike and Ivor, I decided to put the Walbro back in.Walking to the car with key in hand and a toolkit, my brain was saying there's no point trying her but I couldn't resist. One turn of the key and she fired first time. A bit of bluey-grey smoke at first which cleared after a run round the block gently and I was dancing a jig back up the drive!Question is Kiddlies, do I leave the RCM pump in until the re-map which hopefully will be next week and assume the problem is only down to the mapping or do I play it safe and stick the walbro back in anyway?

scatty Posted February 19, 2012 Report Share Posted February 19, 2012 id keep the walbro in till you get there and then put a new rc pump in. it looks like you have just been unlucky and got a faulty one.... Quote Link to comment Share on other sites More sharing options...
STiG Posted February 19, 2012 Author Report Share Posted February 19, 2012 (edited) id keep the walbro in till you get there and then put a new rc pump in. it looks like you have just been unlucky and got a faulty one....Thing is we don't know its faulty. It may just be the mapping. I certainly don't want to say Mikes sold me a faulty part until we know for sure... And I haven't swapped the walbro back. it fired first time with the RCM pump in so I haven't changed it Edited February 19, 2012 by STiG Quote Link to comment Share on other sites More sharing options...
scatty Posted February 19, 2012 Report Share Posted February 19, 2012 (edited) i thought you had swapped the rcm pump back to the original walbro pump????? thats what your first post said... Edited February 19, 2012 by scatty Quote Link to comment Share on other sites More sharing options...
STiG Posted February 19, 2012 Author Report Share Posted February 19, 2012 lol read it again. I think the altitude up there has blurred your vision. I said I was going to. at no point did I say I HAD...... I was about to but I thought I would try it anyway and it fired so I didn't bother...The problem only happens when I give it excessive right footage. My theory, though unproven is that the fuel pump is sucking more through and either flooding the engine or draining the tank. Question is, am I right and will a map correct it, or should I assume the pump is faulty and remove it only to find it is indeed the map.......

scatty Posted February 19, 2012 Report Share Posted February 19, 2012 (edited) in that case leave it in...let the mapper see if theres a problem with either pump or map....ive heard of dodgy walbros, but not dodgy rcm pumps.....

fildigger Posted February 19, 2012 Report Share Posted February 19, 2012 The Re-map will divulge all the info' you are currently guessing at !.....The AFR readings will tell you if the pump is up to the job.....Good luck Paul and lets hope all goes well with the mapping ps. whose doing the re-map ?

Rob5 Posted February 19, 2012 Report Share Posted February 19, 2012 If the car was fine befor u changed the pump id say there is fault with the pump, as changing the pump wont do anything to how the car has been mapped. Quote Link to comment Share on other sites More sharing options...

scatty Posted February 20, 2012 Report Share Posted February 20, 2012 i reckon half your problems are due to putting on all these mods (not the fuel pump) and not getting it mapped in the first place. it cant be the map thats the problem as you havent had it remapped. therefore im assuming its the mods that you have put on without getting it mapped...if that makes sense.im sure it will run sweet as a nut once your car is mapped for the mods you have put on....
