I do in deed it lives I the boot of the car

So is that right for the engine light. Not on on accessory, on during run and off as soon as car starts

does the engine light come on when i put key on to acsessory and run, yes along with all the other dash lights ikons but abs goes out as it should and the engine light goes out after key goes to start when i start the car and stays out.

i seem to be contanly resetting my ecu, and cars never chucked a code even when i was driving with the tps unpluged it never even iluminated the engine light, just ran fantastic, i only relised as i went looking for the cuse of the slight hunting then sore it was not plugded back in, think ill just unplug it again
cars never ran right in the first place

hi every one, i got a question
why does my car run better with my tps unplugged?
my 3sge has a wimpy cold start and suffers from an iratic idle, fine until it comes off cold start at the point my temp needle reches just under half way.
on cold start it will start first time but just sit at idle then if left for around 20 30 seconds it jump up to 1500rpm and happly sit there untill its warm then the idle when warm will dive to just above 600 rpm and car will shake but after 10minutes worth or driving itll settle.
anyway i forgot to plug my tps back in after working on car saturday and i fired up the car and it started perfectly and drove fantastic and had super throttle respone, only down side was it hunted on idle
only about 300 to 400 rpm once warm
so whats the deal? why does car run better once tps unpluged????

Was aCvac leack, I got my hands On a ptfe tape reel and erode every thead and still no joy, I removed the top section and where the bolt holes were the edges were rasied so got drill bit and shamfered the edges, more ptfe tape as I bolted it back up and prob solved! Thanks for the help!

Basically I installed a catch can this morn on my st202 celica and car idles at 16 1700 rpm, can't adjust the idle as the computer does it, anyone got any ideas? Ca is located at place of oil air box and hoses go from pcv to intake, any ideas?

Hi every one,Got uk spec st202 celica gt with 3sge rev3 engine and got a stupid question but I can't remove my dissy!
I have a replacement dissy with new cap and rota etc and I undid the two bolts and removed themand unplugged my ht leads etc and have found before that it was stiff and didn't want to move so I could adjust the timing but I couldn't get the thing off the engine! I pulled and pulled but it didn't want go budge, I thought that it should just pull away from engine?

Hi everyone, looking to put turbo engine in my celica st202 with a 3sge motor,
Want to l
Keep it fwd, will the standard gearbox fit st185 engine; also is the loom swapable?

I give up!
Ok you win im beat,
To up date what I've done, changed the engine temp sensor the ecu one as well as the smaller one, changed the throttle body and gasget, changed the ecu! Rest timing and today fitted a hrc performance fuel pump! Still no cold start!
Looked at dissy cap and looks ok so do plugs, what is going on! Got no codes in service mode!
Why won't it just work
Going to set fire to it I swear
The last thing I'm going to try is the fuel pressure regulator, fitted a ajustble one a week or so back just need an rail adaptor to finish it, I hear if they fail it can over or under fuel so last ditch attempt unlessany one has anything to add? Don't want to sell it just want it to work!

Also don't think 3sge has cold start injector, not in manuel etc. Tryed two icv's, new temp sensor. All I can think of is that it's down to the ecu, fpr or fuel pump! Dont know if fpr vsv handles cold or hot starts?
had car vac tested when I bough it a year ago and removed all lines Saturday went I removed to intake manifold to find the fpr location

Well when I first start the car cold instead of firing up to around 1500 1600 rpm and slowly lowering it just starts and goes to around 1000 which is the idle speed, if reved it'll stall and won't restart, for a good minute or so and only if I have my foot to the floor, once warmed up though reves fall off to around 900 or 800 rpm for a few mintues and then go back up to1000 rpm and runs sweet. Even if started hot or warm it revs up to almost 2000 and settles to idle fine. I'm stuck?

Right, since I'm haveing so much hassle with my cold start I need a little info, I've changed the coolant temp sensor, am tryin to find a fuel rail adapotor so I can fit a afpr, will be getting a hrc performance fuel pump, no one on any forum answers if the fpr vsv deals with cold start? but the last thing is the ecu may be at fualt! So ive found a ecu on eBay near me for good money but it's from a st202 import 3sge, my celica gt is a uk spec car, will the jap ecu fit stright in?

Come on people
The more I look in to this the more I'm confused, doing the rad water today as well the air in take and water temp sensors. Was looking at the vsv fuel pressure thing but don't know if the thing handles cold or ho starts?

Right this is getting on my nerves now, got hold Of a replacement icv and maneged to saw not he's in to my screw and swaped to valve over, but car still won't cold start properly! It's obviously not the valve ski rechecked to two terminals on the diagnostic port and I can hear a woshing sound in the pipes from the fuel pump, short of having to spend over £200 on a fpr and pump and hope dose any one have any advice?

The company ecotek do a foam called the power boost
Engine enigizer, you warm car uP, pull the Pcv pipe rev Car to 2000rpm and spray it in, cleans
The hole engine though the heat. Car will smoke like mad but it's all the crap coming out the motor, good stuff or ammate of mine rekons a drop of redex in each bore and start it but it sounds a boge to me, might stil work though

Was leaning toward the pump, so I shorted the b+ fP terminals on the dcp1 and had the key to on, had a wosshing sound but not in the know enough about the pump in the first place, I started the car and same business no cold start so I'm no closer to finding out weather or not it's the icv of the fuel pump!

Right, I've found that when I have a tank of fuel the car starts a little better and starts cOld at around 1200 rpm just about and won't stall out if it's reved, butif the fuel gets low like in to the last quarter of the tank the car just about fires up and just idles and stalls if reved! Could this issue just be not my Icv but my fuel pump going to hell? Not priming and no holding cold start psi?
Anyone??????????????

Actualy, me and a few other peps ok ow have done it, my xr3i and my crx sol both had four branch manifolds. It's suppost to keep the gasses hotter and thinner so it flows faster down the system and aids response etc, my gt has a standard four branch that I'm going to wrap, only as my standard one Is rated to 500 brake supposedly. It really depends what sort of manifold you have and will it stand up to the extra heat and won't go bang!

Ok started up the car cold last night, and It catches but only hits around 1150 1200, and if you rev it it stalls and won't restart, you have to floor it while cranking to get it to start!

my valve it self moves easyer than the replacment i bought funnerly enough but gave it a blast with some carb cleaner today anyway, all i can do is remove the air filter arm amd fill the valve and air pipe then start the car, it sucks it all though, i did run the tank right down thursday wirdly and i know it puts a strain on the pump praphes i sucked up all the from the bottom of the tank?
regardles i put the replacment mag motor back on and the car idels swweeeeet, just have to see how it fires up when i leave work tonight and im posting off the valve back to the sender for a replacment to see if thatll solve it!

Ok I refitted my originall mag motor to my idle control valve but it still won't rev up on cold start, revs up fine if started warm! Really need help wit this one ! Fuel pump, fpr? What?

my st202 gt 1994 3sge has had a crap idle but perfict cold start since i bought it last year and i finaly got round to getting a second hand icv from a brakers but found that i couldnt get my old icv off the throtle body, so i swaped the magnetic motors over and refitted it to the car, fired up the car and it runs lovely idles sweet as a nut but went to start to start it two days ago and the motor just cought and refused to start yesterday and strugled to start today! even i reset the afr! it seems ive just swaped one problem for the other,
so anyone got any advice for me?
cheers j

Well seeing as Toyota are the only place to buy the injectors new for my car in the uk I phoned them, £883 for 4 injectors! I don't think so some how, and getting them cleaned wil cost £60 each plus the vat so that'll have to wait, so it'll be Sevral bottles of injector cleaner all at one then!

ok cheers for the advice guys, i figured that with slitly bigger injectors running standard psi it would benifit it and run nicer and perhapes make a little more power and with the ecu afr relurn and a fpr i could tweak it and make it even better
