Nov 1, 2008
London, UK, Europe
So I picked it up this morning yay. drive back was ok but nervous as an older car and not knowing the full history! but I made it back all ok and well.

there are some problems with it but im currently helping my 91 Talon friend here restore him so I have to get his done first before i can start mine.

current known problems are listed below!!

* Cold start issue! possible ecu temp sensor or fiav issue. intake temp sensor was replaced i was told but to rule it out i might do this again myself with a good known brand i trust so its up to my spec and detail

* suspension needs addressing! its soft and its old so thats pretty simple for me to tackle.

* tires are old and soft / deflating so i got 2 option here! replace the tires and refurb the oem wheels or....... put my rare 17" bridgestone wheels on and new tires? if i did this then i would need to lower it a bit but that might be part of the suspension refresh plans?

* the trans is stuck in third gear so its not nice on a highway nor pulling away! so for this i plan to drop the pan and clean the entire valve body out and install a new filter. I dont know whether to install a shift kit while im here to make it a better system overall? OD does not work so It may need a good clean and dismantle anyway.

* the timing is an unknown so thats one of my vital parts to get done and out the way also. all fluids will be refreshed inc any sensors and stat along the way! might as well.

other then those issues its a really nice car! I got all the oem parts with it so things like the air intake will go back to oem and also the steering wheel might go back to oem also as i dont like the one thats on it.

for a 67k mile car it shows its very clean and really rust free!

other small bits i need to address are passenger window sticks and seatbelt does not work so never owned a 1G before I now have some new learning to do.

the other long question is............. do i put my old turbo kit on it from my 2G?? this maybe something I do later on if I do decide to upgrade it.
Actually decided and had time to work on this talon! Shocking...

So over the last 2 weeks i have started to work on the main things and a clean up of parts.

AT, the valve body came out as i wanted to install a shiftkit and change the fluids and filter anyway. Part of new ownership is going through it all. The fluid was dirty snd filter was some weird double sided filter mesh so i got a NOS oem unit and plenty of spares LOL. Shift kit went in ok as normal and done a few of these now so getting quicker at them. The seperator plate was in good condition thankfully so did not need a spare but with little miles its no wonder its not damaged. This is now back in currently and just awaiting the atf fluid to turn up then i can finish this all up.

The TCU i read was an issue so i took this out to confirm the capacitor had leaked and its not that bad, i got new ones on order in the exact same as oem so once out will clean around it snd protect it once all back together.

Working on some of the corroded parts im blasting to remove rust, flaked paint and painting these to look nicer and fresh again. And it makes a huge difference. The valve cover is next and i will be re painting it in oem colors just so its as original as possible. It needed a clean so its being unltransolic cleaned as under the cover was a bit of oil staining which is not nice so will clean that off and inside the baffles also due to the age.

I have everything for the new timing belt and pullys and stat to go on so this will be 100% new also.

Once all this is done im hoping i got all gears again and its now possible to get the yearly i spection done. I would love to use this during the summer months this year. Me and another local 1G (gsx) i am restoring shortly will roll around together, he will be faster but having TWO oem cars is something of a great thing. He trust me to do his restoration and work on his chassis as no one else likes to for somereason LOL so I am happy to help him and get stuck in for him on the chassis as he is the original owner also! Together our chassis will be amazing to drive about as a pair.

Semi productive weekend on the 1G.

Got rained out and was cold so only could do so much but did what I was able to do as I got stuck on 2 things but all being sorted.

This car was an unknown to me I want to go through everything, so I removed the timing belt and pullys to find the oem belt had been replaced with a gates belt BUT the pullys were old and shot! Even the balance belt was changed but seems as if they did not bother with bearings at all!!! Pump was very old! This is why doing maintenance on a car you got is key as you DONT know the history and best to do it while you own it now so it's peace of mind.

I then cleaned a few things up along the way started on the oil service and plugs, did fuel filter also which came of nice and easy for the banjo bolts.

Timing cover looks brand new apart from the rubber being dried up but im trying out some new degreaser lemon cleaner and its doing an amazing job this far of making things really really clean.

Since sunday has been a washout i decided to clean up the TCU! I read some tips on clean up and preventive maintenance once done so that's good to know and learn more on PCB boards. the damage and leak was not as wide spread as i have seen online but still messy. Clean up was slow but fine brushes helped in the small gaps and looks a whole lot better than before! Then i got to de-solder the capacitor then clean under there which also makes life easier. Removal was harder then the install of the new one only because you needed to heat, hold and pry the old one out but it all released ok and the new one looks right at home once again but just smaller due to modern technology and sizes. So with that done, I HOPE this has solved the 3rd gear only limp mode! Time will tell when i can get it all timed up and started and hope when i select 1st i get movement..... Will be amazing if it does!

Thats about all for now. I have some cool pics shortly as i have gone over some parts to really help make it refreshed and clean once again!

Another weekend and another eventful time on the 1G trying to bring it back!

Was a great weekend (mostly)

I have blasted and painted alot of parts! Pullys, intake, random covers and brackets that had surface corrosion that was right in your eye sight so those were taken care of. Then i had the VC cleaned up and it took a bath in the ultrasonic tank as it has never been cleaned! The old paint was flaking from alloy corrosion, the amount of carbon that was inside the baffles was shocking! Its all 100% clean now and i opted to paint it a slightly lighter metalic silver. I like the darker silver but switched it up some so the sun hits it then you see some nice speckles for a modern touch! Also the VC bolts were replaced with noce new shiney ones. Old rusty bolts here would not look nice so is the ONLY big change really from oem.

I used my very new still red Toda belts. All new components though. This is hidden so no worries on it but i know its a strong belt.

Engine was put back together and re timed and managed to fire it up! Woop woop. I still have a cold starting issue even though a few sensors are new so i have to go and test a few like the TPS, CAS and see why its not picking up straight away. I have fuel/pressure and spark! Its just not igniting it straight away!

When it ran for a bit the cel came back on so im borrowing an odb scanner and using the obd2-1 adaptor going to see what that shows me as the problem! But i do believe it is a sensor of somekind! Just got to figure out what sensor??? I have a new cas on hold incase its that which is the later 93/94 dome cas as its better,

Transmission was all filled and works but... Stuck in 3rd gear still! (Damn it) So the TCU capacitor was not a solve so i dont know what now on that so i have printed off alot of the manual for testing circuits and eed to make one of those test rigs with lights or switches i have seen. @1990TSIAWDTALON did i read you made one to test trannys on? I believe it was you but no idea where i saw this or what you used?

Other then that the car does move and driver forwards and such. So thats a good result and knowing all pullys are new and not old and corroded as they were very bad! Like bad bad. I have peace of mind now on that part.

Next parts are as follows.

* Replace the vac hoses to all black and confirm the route of them also. (FSM manual printed off for this).
* Start looking more into the trans issues again.
* Do more yesting for the cold start problem.

So not much more but a noying ones to do and time consuming of everything.

Not had much time on the 1G recently, today was all I can do and even that was to fault find my current issues it has and see what i can find out.

baseline on problems as maybe someone knows the best way to resolve it vs what I am trying.

*1 Hard cold starts
*2 once started tapping the throttle kills the engine
*3 once hot and moved and back into part idle shoots up to 1600 rpm
*4 still stuck in limp mode 3rd gear on TCU!

So TODAY was to concentrate on the ENGINE SIDE ONLY! So *4 is out for this one.

decided to try a different CAS to see if that was a problem with the cold starting - FAILED!!! makes no difference and works with it still
Once I did that I then went to pull codes and I got 4 which are
13 IAT
14 TPS
21 ECT
25 Baro temp

from here I go into checking mode for things.

* TPS - Checked 2 of these and both come back fine with resistance in spec of about 5 ohms, REALLY not sure as to why this is coming up then. does the 1g throttle stop sensor/clip throw a CEL if not plugged in or corrosion as inside its a bit corroded? I don't know otherwise why the TPS code came up and all I can think of is replace it or is it the ECU problem causing this to throw up?

* ECT - THIS is brand new! out the box and non OEM but doubtful it's bad. I guess testing in hot water and resistance is required for this one?

* IAT & Baro temp - This shows me it's possibly the MAF sensor but I plugged in a new one (OEM) as the car ran the same, once you unplug the sensor it tries to die. unsure of the test procedure here as nothing is really listed for the DSM. just a temp test but forget where I even saw that now

I also checked the ISC as for some reason the BISS is all the way in!!! like fully in! Turns out the ISC coil 3 is dead and does not move or respond. So I got a spare tan one so can test that and see if it helps part of the issues along the way of something working again. i might just get a black one to be safe and new.

once all those were checked I pulled the ECU as people say they are a problem in the 1G like the TCU's are. bloody things LOL
once home I opened it up to find it had been worked on before, it's not a NEAT job by any means, there is surface corrosion still but not green and the covering is all white so possibly bad covering PVA glue or it's overheated causing this.

IC105 and 107 look good so they have not blown from the ISC so that's good to find. but I'm concerned the caps have not been replaced greatly with the covering over the corrosion still and now flaking off! So I am considering either redoing it or sending it to ECMlink to get the ECU fully tested and replace and recoat the thing since I have zero way to test the entire ECU working

OH and to finish off the VC looks great in the sun with the metallic sparkle.
