hey guys. I got a problem with my soarer TT stalling. Most of the time it's fine but every now and then (atleast a couple of times a week) when i start up my baby she sounds like she's struggling to idle. she'll keep doing it until eventually it stalls, but if i rev it a little to try get the revs up she stalls straight away. When i go to start it up again i hold the revs at about 2500rpm and it just dies and cuts out. It's as if the accelerator stops working and the revs just drop from 2500 to nothing even while i'm accelerating. This happens 3 or 4 times and then eventually it starts normally. Has anyone got any ideas because it's driving me absolutely insane. Especially when i'm trying to leave a car park, start reversing, and she stalls, then it takes me 3 or 4 times to get it going again. I swear some people would think i'm an absolute retard stalling an auto. I've taken it to a mechanic, he fixed up the tuning and checked it out. He said it sounds like a fuel pump problem but he had a look at it and said that the fuel pump seems to be fine. Also, it used to have a kill switch installed. i removed it because i though this was why it was stalling. could that have had anything to do with it? Please help. I cant' stand it. I love everything about my soarer, EXCEPT FOR THIS

Sounds like it could possibly be your fuel pump ecu? Theres a bypass you can do but im not sure how, there is a few posts on how to do it but you might have to search them out.

i pulled out the main ecu as it said in the new soarer owner section and that did nothing. You wouldn't have any clue what section i'd find out about resetting the fuel pump ecu

I searched for ages but unfortunately this was best I could find http://www.planetsoarer.com/IAC/iac.htm hope that helps. Your not looking to reset the fuel pump ecu, you actually want to bypass it completely. If this fixes the problem then you know the ecu is faulty and you can replace it. apparently running without the fuel pump ecu damages your main ecu eventually.

problem seems to be solved Luke. Hasn't stalled for a couple of days now which is a good sign. I guess i'll give it a week or so to make sure that was definitely the problem before i replace the ecu. Thanks again for your help. It's a big relief. Fingers crossed it stays that way. Cheers

Excellent mate glad you got a good result fingers crossed it stays fixed. Got any advice for fixing a melted piston for $7.50 and half a pack of chewing gum? hahahaha

Fuel pump ecu. I just bridged the Fp and B slots in the diagnostics port in the engine bay with a paper clip. Works a charm. I haven't had a problem since i did it in december last year. I got a new ecu but am yet to install it. Good Luck with it

as far as i know what luke has said is correct. i spoke to my mechanic about it aswell and he said that for obvious reasons it's better to replace the ecu and have the fuel pump running between a hi/low setting, as that is what it's supposed to do in a soarer, but most cars, pretty much all as old as a soarer don't have ecu's to control voltage, they just run at 12v

If it runs at 12v it wont make sweet all difference.. However Bypassing and bridging it means the Fuel pump will be on, and in the case of an accident it would still be running and cause a dangerous situation .
