Sorry, if I what I said was originally uncear guys, it was like 1:30 in the morning, and I was running on fumes. 3p141592654 seems to have gotten the gist of what I was asking though, which was basically, since I had just cleared all of the codes, and let the car idle for about 10 or 15...

Yeah, I understand that. Perhaps I worded this poorly, but my concern was more or less is it possible that those were the codes being throw when the CEL came on? Perhaps the sensor or wiring was loose and at WOT, it shorted out? These seems like codes that would cause a constant CEL, so why...

Hey guys, I just got my 89 Supra (Auto) up and running again recently. Everything had been working fine on it until Sunday when it threw a CEL about 30 miles from home. I was able to find a bobby pin and check the code, which was 21. I ordered a new O2, and replaced it this evening, then...

Really? No one has any more information? Can we start with the simplest question, which is, should code 14 cause a no start? Because based on what I have read, the answer is no, and that the car should still start, but the ignition timing might get funny and misfire since the ECU can't tell...

Alright, I have run through the entire TSRM ignition system, and everything has checked out. The only thing I can think of yet is to check the continuity of the IGF wire from the igniter to the ECU to make sure there are no breaks. Is there any way to test that the IGF signal is being sent...

Alright, I know it's been a few days, but i finally got around to finishing testing the igniter per the instructions. Everything checked out according to what the page says I should see, although it does not give any indication of what an acceptable resistance to see would be, so I have no idea...

Alright, so I started trying to test the igniter following the procedure outlined below, but I have some questions. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=IG&P=15 Step 1 checks out OK (Aside from only seeing 9 volts, which is due to the battery being low and only putting...

Alright, the CEL is back on now. One of the fuses was blown, but not on top, more to the side, which made it very difficult to see. The diagnostics returned codes 14 and 51. Both of these codes list the ECU as a problem area. Should I even bother trying to test the ignitor, or just go ahead...

Wow, no I did not. I pulled the cover off and took a look at it, but our garage is rather narrow (too narrow for my fat ass to be able to manipulate my way under the dash to see in there), and it's been raining for the last several days, so I have not been able to push it out and work on it...

Alright, well, as expected, it cranks but won't start. I have a couple of questions here. 1.) If this turns out to be the fuel pump, does an aftermarket fuel pump like a Walbro require an AFPR, or is the stock FPR capable of handling it? I search around, but didn't see any mention of an...

You just saved me hours. I had already replaced all the fuses under the hood, but I forgot about the link because I didn't have one anywhere in the garage. Made a run to autozone to pick one up, and everything seems to up and running now, and it at least tried to crank over, but the spare...

Hey guys, So I made a pretty dumb mistake the other day. We have an 89 that has been sitting for a couple of months. We currently have 5 cars, and I was too deep in other projects to get to this one. Well, I finished my other project enough to get it out of the garage. The other night, I...
