Car wont start hot
 

Carfanatic89,

I know you are frustrated over the problems you have had. It seems like you are close to solving the problem.

I would like know about the info you have on getting ECU's rebuilt/ refurbished in case I have that problem I will no where top go to get help?

Thank you and I wish the best.

As far as parts go the 4 best places to buy parts from are: Rockauto.com, Horsepowerfreaks.com, partstrain.com and ebay.com (in that order) . Yeah maybe when I get alittle farther in life I might be able to work on the supra. Im only 19 and I have plenty of time to get another supra or fix this one. But at the moment I need a ride that can take me back and forth to work relaibly. My supra is the reason I got fired and had to come back home to live with my parents. Im ready to get the hell out of the house again. lol

But still it eats me up to not know whats wrong with this car. I love my car and I dont wanna quit, but I have to do whats best for my situation.

Find someone else with a supra and ask if you could borrow their ecu for like 10 minuets, just swap it and see if it solves the problem, if it does there you go, if not move on from there

Your a funny guy, lol im the only and I mean only person with a supra. Im known as the guy who has a supra. there aren't to many people in the country that own a supra. I try to explain the parts and what they do and ppl give me a srange look thats the main reason why if I take it to a local shop. It turns out them asking me questions. lol

Have you tried SupraMania yet? They have a lot more activity and people that know the car inside and out.

I copy pasted everything from these post over there and their telling me that they dont know either.

I missed the thread where you gave me the parts info. Thank you very much. I understand your situation. I wish you the best. One of the days I hope to see a thread telling us you got your supra running great.

If you think it may sit for a long time you may want to lubricate the the cam, valves and pistons with Marvel Mystery Oil or some similar lubrrcant. Turnig the engine over manually by using the the harmonic balancer bolt would be helpful too. The lubricant will help prevent problems like I have currently, two stuck valves in the number one cylinder. I lubed everything but I was busy and let it set too long withyout lubing the cam followers.

I wish the best.

Quoted on Dan:Thanks that was more helpful, I just took off the timing car covers to make sure the cam gears haven't jumped a tooth. everthing checked out and I started it and ran ok. The fuel pressure is to high right now to crack the line, ima let it bleed off some pressure. Then ill put the guage back on to check and get a fuel curve of all conditions and see what I find. As far as a wide band goes, do they make a wideband sensor that will bolt inplace of the old sensor to run a guage and send feedback to the ecm. If so can you tell me where I could buy one. I have ngk wires on right now. I have to wait till next paycheck to get ngk plugs. Im also going to put on a new intake. I think the old ones fine, but it is old and has some stress cracks in it and might be letting un-metered air in the engine. Thanks again, I know im really close to find out whats wrong with her.

Having a very high fuel pressure is quite normal according to your situation. Where are you planning to buy your plugs?

Spark Plug
 

I have the same problem with my Cavalier Z24. Starts no problem when cold, but the minute a drive somewhere and it gets warm, my RPM meter either bounces till it dies, or it just wont start.
If the spark plug wires are turning white, they probably need to be replaced. Check them for thinning. Also, if you popped out your spark plug and found oil, you might be having that problem again. Check it one more time to make sure. You might not have fixed the initial problem.
Someone once told me that as the car gets warm the spark plug wires expand. This might be why you are having problems, if they are old and thinning.
