We put a noid light on the injectors and cranked it is barely lighting up. I have swapped out ecus so I know that is not the problem. Could it be a bad ground somewhere? What would cause this issue?? Oh and my security light stays on when I turn the key on and when cranking the car all the time...

that is the same issue i am having with my 89 mk3. I bought the car used 2 years ago and someone retard went through it. They cut the cat off and had the firing order messed up. I got it to run but barely ( sputters and stalls ) I have tried numerous things on here. I replaced plugs, fuel filter...

Does anyone have detailed instructions to adjusting a TPS? thx in adavanced

I am trying to get my mk3 running for a year and a half but not having any luck. It has been in multiple shops and is really becoming a money pit. I know the problem or problems the car is having is minor. I will pay someone that knows these cars to diag the problem and fix my car. or possibly...

My alarm is acting stupid. Even when I unlock the doors and trunk. It still doesnt disarm itself. Is there a detailed thread I can read or is it simple to bypass?

I bought a used 89 mk3 a while back we have been trying everything to get it running no luck so far. I think it has something to do with the cars factory alarm system. Would this thing go into some kind of safe mode and not allow the car to start? how can I bypass this because I only have the...

Could the tps stick open and cause it to act this way. or is my cps bad with the resistance that high. Also I forgot to mention this car has a factory alarm system and when u crank it the security light stays on. Now the car wont start at all. Does the security system cut out spark because i...

today i checked the car out and the only code that came up was a 51. which is the ac switch and tps. I dont even have the ac hooked up. anyway I did an ohm test on the cps and the resistance was 238 when cygnus says it should be 140-180 ohms. Could this be my problem. I also checked the timing...

Ok I will check the codes and go from there

one more question. If I get a lexus ls 400 AFM do I have to get 550cc injectors, or can I run it with the stock injectors and stock turbo? Will it cause a power lose? When I set the timing does the diag box have to be jumped?

I cannot check timing because it wont stay running long enough.

I bought an 89 mk3 turbo a year ago. It is currently at my fathers shop about 100 miles away from me. We have both been tinkering on it the past year. He is a good mechanic but doesnt know this car that well. The car doesnt have exhaust on it because the people we bought it off thought the cat...

Before I posted some issues that my 89 supra turbo was doing. I have it narrowed down to the ECU. The problem is I have an 89 and I cannot find an ECU for that year. Will the yellow connector 87-88 ECU work the same? How hard would it be to make it...

Thanks for all the posts guyz and advice. Ive purchased an adustable regulator on the net. Just for later purposes. If that doesnt fix it.I will pull the F.rail and injectors and inspect.I noticed that some of the bolts on the upper plentunm were loose. My dad seems to think its a bad injector...

A few months back I purchased a 89 supra (7mgte) for $300. The car is currently not running. It has about 2-3 lbs of pressure. I thought for sure it would be the pump and I put one in it and new filter and its still doing the same thing. The car will start if u feather the gas when u crank it...
