TedEP91 Posted January 13, 2014 Posted January 13, 2014 Guys I'm a bit lost, have a glanza 96 with large front mount, decat with straight through all the way, ct9 hybrid turbo afpr set to 2 and half, relocated air k and n air filter and a baileys blow off valve and boost bypassed so always on high.. When I put my foot to half throttle it boosts to 0.5 but if I try any more is starts like jumping and restricts itself any ideas?? Teddy Quote
Zeldoz Posted January 13, 2014 Posted January 13, 2014 It may be creeping to 0.85? Or is bang on 0.5 from your gauge and spluttering? Quote
Ollieh17 Posted January 13, 2014 Posted January 13, 2014 (edited) doesn't sound like fuel cut if its jumping? My experience of fuel cut is like hitting a brick wall and stopping. Does it appear to misfire when you reach 0.5bar? Edited January 13, 2014 by Ollieh17 Quote
TedEP91 Posted January 13, 2014 Author Posted January 13, 2014 Yeah it's like misfiring,before it started it was boasting to 0.8/0.9 ish fine Quote
Azz Posted January 13, 2014 Posted January 13, 2014 Sounds like not enough fuel, I'm sure the standard furl pressure is 3-3.5bar.Try turning your fpr up a bit Quote

mikey4410 Posted January 13, 2014 Posted January 13, 2014 fueling varies with different cars because fuel pumps and rrfprs .you can give a rough guestimate but to put it to a said pressure andthink ure gonna be fine is hazardous to say the least without checking ure fueling on an a/f guage.madness.

Ollieh17 Posted January 13, 2014 Posted January 13, 2014 I had a similar problem. How long ago were the plugs changed? I changed plugs and ht leads and it turned out to be a bare wire from the ecu earthing itself. Check for any splits in the wiring up by the ignition coil on the bulk head where the king lead plugs into Quote
TedEP91 Posted January 13, 2014 Author Posted January 13, 2014 2 of my friends said new rotar and dizzy and it should be alright and I had new blue magnicor and plugs 1 month ago And I checked all leads there all fine, what about shall I take dizzy cap of and clean all the points with wd40?? Quote
Ollieh17 Posted January 13, 2014 Posted January 13, 2014 When you reach 0.5 bar what happens? Does the car stop like you've slammed on the breaks or just seems to misfire and splutter a bit? Would help rule put fuel cut, the way you described it doesnt sound like it to me Quote
TedEP91 Posted January 13, 2014 Author Posted January 13, 2014 Misfire and splutter, it's definitely not fuel cut I hot that about 0.9 ish gave me whiplash lol Quote
Ollieh17 Posted January 13, 2014 Posted January 13, 2014 sounds like an ignition fault, similar to mine too. Does the check engine light come on? Quote
TedEP91 Posted January 13, 2014 Author Posted January 13, 2014 Yeah if I full throttle for long enough mate ... Quote
Ollieh17 Posted January 13, 2014 Posted January 13, 2014 have you done a diagnostics on it? Try this mate and see what the error code is http://www.toyotagtturbo.com/forums/showwiki.php?title=EFI+self-diagnosis+system Quote
TedEP91 Posted January 13, 2014 Author Posted January 13, 2014 Bust when I start it the light goes out? Quote

Ollieh17 Posted January 13, 2014 Posted January 13, 2014 the fault code will be stored unless the ecu or battery has been unplugged. I would do that before worrying about fueliing Quote

TurboTobz Posted January 13, 2014 Posted January 13, 2014 Standard fuel pressure is around 2.4 bar. Quote
fremyjay Posted January 16, 2014 Posted January 16, 2014 (edited) Sure you didn't get faulty plugs or leads, sounds like mine when a plug was playing up Edited January 16, 2014 by fremyjay Quote
pick1 Posted January 16, 2014 Posted January 16, 2014 Process off elimination I.e rotar dizzy , plugs , leads , earths etc always best to get it checked on the rollers though if u gotta adjust fuel pressure etc though mate just go steady with it and get it checked is my opinion not worth your engine going bang it could be something simple Quote
