Replying to: sbaker75 (May 06, 2009 12:37 pm) The injectors power come from the 30A AM2 fuse, then thru the Ign switch to the injectors, and then from the injectors grounded and controled thru the ECM. Since your engine will run on starter fluid, I would assume that all of this power is working okay. If you do determine that the computer isn't turning on the fuel pump circuit relay, then I guess the next logical approach would be to try and determine whether some input to the computer is bad which is telling it to keep the pump off....or whether the computer itself is bad.

Replying to: sbaker75 (May 06, 2009 3:38 pm) "so if I can run on starter fluid does this mean the injectors are working?" - No, that means your injectors don't appear to be working and delivering fuel. Could be don't have enough pressure on the rail, the computer isn't telling them to fire, or some number of them are defective. If you are able to run on starter fluid, then the compression and spark appear okay and your problem is in fuel delivery. |

Replying to: kiawah (May 06, 2009 5:20 pm) Check the inj fuse or put a simple test light on one of the connectors to the injectors and watch it light up when you turn it over.It should be in the engine compartment fuse box. You can hear them clicking when you crank it over if you place a hose or long srewdriver on the injector and other end is in your ear. You also have a cold start injector, and need the air duct connected, and cold temp sensor working properly to get a cold engine started easier. |

what is the purpose of alternator in the car? I am asking this because my 1995 Toyota Camry stopped at the traffic light- after I had stopped at the red traffic light. And some one told me it could be the alternator. what do you think. Here: I was driving the car and when I had stopped at the red light the camry just stopped and would not start. Now one guy is telling me it could be the alternator. I have not yet taken the car to repair shop or dealer as it is stormy weather here. That is why I am asking this. Thank you. I don't want to get ripped off by dealer or car repairmen so I am trying to find out this as much as I can. thank you

Replying to: chilon (May 06, 2009 3:29 pm) So your headlights, radio, starter, fans, electric windows, all use power from the battery. The alternator puts the power back into the battery to keep it charged. And to answer your question, YES, this 'could' be your problem. But as previously said, so could hundreds of other things be your problem. Just take your vehicle to a reputable shop, you're worrying about this way too much. They'll have one of the technicians look over your vehicle to figure out what appears to be working and what appears to not be working, and zero in on the problem area. It's not hard to do with someone who is knowledgeable.

Replying to: kiawah (May 06, 2009 3:36 pm) Did you do the Battery test? The alternator keeps the battery charged if the battery is charged the Alternator works. I can't believe people tell you it might be this or might be that. If you desribe the problem correctly, then they should be asking you more question narrowing down the problem, not the other way around. How can you find out what is wrong if you can't answer the troubleshooters question. You shouldn't be asking what this does or that. They should know what it does and be sure it is this or that not it might be. I can tell you what is going on if you do the test I asked you to do. This is basic troubleshooting 101. I saw a 95 Camry at the junkyard today the fuses are right next to the battery did you see them?

Replying to: rearwheeldrive (May 06, 2009 11:33 pm) The poster (he/she) is not technically proficient, and any even basic problem isolation techniques are difficult to do, particularly hard if there is no underlying understanding of why things work the way they do. He/she could spend hours and thousands of dollars chasing 'it could be this', or 'it could be that'. The absolute best direction in my opinion, is to get the vehicle to one of many competent shops who very quickly can isolate the problem down just by observing the vehicle with some very basic testing. And by the way, there are a number of fuse boxes in that vehicle, and the main one is by the drivers left knee, behind the ash tray.
