seth3030 Posted December 31, 2009 Share Posted December 31, 2009 i thought i just didnt have enough gas cause it was really low, i added two gallons and it still wont start. it tries to turn over but it doesn't start. Link to comment Share on other sites More sharing options...
seth3030 Posted December 31, 2009 Author Share Posted December 31, 2009 could it be the engine temp sensor by chance? Link to comment Share on other sites More sharing options...
Log1call Posted December 31, 2009 Share Posted December 31, 2009 No it will almost certainly not be the temp. When you turn the key on can you hear the fuel pump running in the back of the car? It should come on for about two seconds when you turn the key on. Can you remember hearing that noise before and if you do remember the noise, does it sound normal? If you did run the car out of fuel they sometimes need quite a bit putting back in to get the fuel pump submerged so it will prime. You could try putting more fuel in there, then turn the key on and off about twenty times without trying to start the car. That will make the pump run for the two seconds I mentioned and fill the fuel filter and lines again. Then try starting it. Link to comment Share on other sites More sharing options...
Cougar Posted December 31, 2009 Share Posted December 31, 2009 I doubt the sensor is the trouble. Try spraying some starter fluid into the intake to see if that will help get it going. If that doesn't work then there may be a problem with a timing belt. Link to comment Share on other sites More sharing options...

Gloyale Posted December 31, 2009 Share Posted December 31, 2009 (edited) No it will almost certainly not be the temp. Why do you say this? I have seen a least 3 different First gen legacies not starting because of faulty CTS readings. (resistance so low that the ECU thinks the car is at 280+ degrees.........injects almost no fuel) ANYTIME i have a no start, first thing to try is simply unplug the CTS. Unplugged, the ECU will default to rich starting program. It is worth checking. Edited January 1, 2010 by Gloyale Link to comment Share on other sites More sharing options...
Log1call Posted January 1, 2010 Share Posted January 1, 2010 I said it because in the cranking situation there are only a couple of sensors being used and the temp sensor isn't one of them. If it fired a bit, tried to go, then flooded, I'd have said something different though. Also, his suspicion was that he had run out of fuel so I was going with what the customer says... they are often right. Feel free to make your own suggestion though.

Log1call Posted January 1, 2010 Share Posted January 1, 2010 Gloyale ... I just went a checked and you are right... the temp sensor is monitored at start-up after all. Me bad. Despite that oversight, the rest of my reasoning remains the same. I don't think it fits the circumstances. Link to comment Share on other sites More sharing options...
seth3030 Posted January 3, 2010 Author Share Posted January 3, 2010 added more gas (4 gallons total) fuel pump is working and i tried starting multiple times it turns over but wont start. so nothings wrong with the fuel pump or battery what should i try next?

markjw Posted January 3, 2010 Share Posted January 3, 2010 Did you try spraying starter fluid into the intake? If it starts and runs for just a moment,you can easily eliminate a no spark situation. Link to comment Share on other sites More sharing options...
Log1call Posted January 3, 2010 Share Posted January 3, 2010 Yes that is a good simple test for lack of spark and lack of fuel. Next step is to extract trouble codes, check for spark, fuel and compression. As has been suggested(well I think it was suggested), you could try pulling the temp sensr off and see if it makes a difference. Just what you do first depends on hw familiar you are with cars, subarus and troubleshooting really. You should check all the fuses. try the ether. If it kicks a bit it will show it has spark. If nothing happens at all I'd pull the plugs and check whether they are wet(or not), put them back on their leads/coils and check for spark anyway.

seth3030 Posted January 3, 2010 Author Share Posted January 3, 2010 so just put it in where the air filter house leads to? Link to comment Share on other sites More sharing options...
seth3030 Posted January 5, 2010 Author Share Posted January 5, 2010 my check engine light code said 13 a cam position sensor could this be the problem? Link to comment Share on other sites More sharing options...
seth3030 Posted January 6, 2010 Author Share Posted January 6, 2010 ok so i was looking around and found some wires that were chewed through, it was from a wiring harness right under the big black intake hose and the wire runs down to the drivers side of the engine to the timing belt case what is this part? and how can i buy a new connector for it?

Fairtax4me Posted January 6, 2010 Share Posted January 6, 2010 Well that would probably be the problem. Easiest thing is to just patch in some new wire. Do you know how to use a soldering iron? Link to comment Share on other sites More sharing options...
Log1call Posted January 6, 2010 Share Posted January 6, 2010 Yup that could very likely be your problem. As has been said, you could solder in new wires but they need to be coaxial wires and up to the automotive conditions, so flexinle wires, fairly thick, heat and oil proof insulation. It's probably easier to go to the wreckers and get a new/secondhand cam sensor. When you run the new wires or fit the sensor make sure it runs just where the other wire goes. The coaxial wire is to provide a shield from interference from ignition and alternator wires. Even with coaxial wires they can pick up interferance and cause problems so follow the old route carefully. Also, if they wire has actualy been "chewed" get some rat poison and stick around your car storage area... Rats can cause major damage to cars, hell, if they eat enough wires they will turn your car into a writeoff! Link to comment Share on other sites More sharing options...

twhb Posted November 29, 2010 Share Posted November 29, 2010 Why do you say this? I have seen a least 3 different First gen legacies not starting because of faulty CTS readings.

Cougar Posted November 30, 2010 Share Posted November 30, 2010 The CTS is the coolant temperature sensor an you just unplug the connector to it. It might be located on the passenge side of the engine. Link to comment Share on other sites More sharing options...
mikec03 Posted November 30, 2010 Share Posted November 30, 2010 twhb The CTS is located in a very difficult spot to reach on the coolent line exiting from the engine [and it is on the passenger side]. Search for a DIY instruction. There's a lot of hoses and wiring in the way. Link to comment Share on other sites More sharing options...
Olnick Posted November 30, 2010 Share Posted November 30, 2010 Seth, try a search for "coolant temp sensor" or "ECTS." There are some helpful threads, one with pix as I recall. Link to comment Share on other sites More sharing options...
