#75 of 98 Re: 1995 Camry engine died as I was driving [steino1] by kiawah Sep 22, 2008 (11:25 am)
Replying to: steino1 (Sep 22, 2008 10:27 am) Could be a thousand things.   Does the starter crank the engine, indicating that the battery has voltage?   Have you had the timing belt replaced in the last 90K miles? Could be the timing belt broke...so check to see if your camshaft is turning.   Assuming that is okay, pull a plug and check for a spark.

Replying to: kiawah (Sep 22, 2008 11:25 am) This should be easy if it died and wont start. Like the last post check engine timing belt then check big fuses outside in the engine compartment in the black box.   The answers in the black box.
#77 of 98 Please help, car keeps stalling by hannabanana Oct 02, 2008 (11:10 am)
I have a 97 camry v6 with 160k. It will crank and start just fine, but after about 3 seconds it dies like it is out of gas. If I restart it, it will crank normally and start right up, and do the same thing. It dies every time, without fail. If you press the pedal, it will run a little longer, but the rpms keep falling until it dies. If you hold it at 3 thousand or higher, it keeps running, but roughly. I don't know too much about cars and can't afford to play the guessing game. I think it must be fuel delivery. could it be a fuel pump? fuel filter? fuel pressure pump? some kind of sensor. any ideas are appreciated. thanks

Sounds like an air induction problem or the computer getting a bad fuel/air mixture signal.   Check the duct going into the intake and big rubber hoses attached to the intake manifold and this duct. It starts at the air filter. At three thousnd it might not pick up the air leak since more air is running through the engine at that speed.

Replying to: rearwheeldrive (Oct 02, 2008 10:23 pm) I missed runs rough after starting at 3000 rpm's.   I d do your own compression check on the front bank and the one spark plug on the rear bank of cylinders. To get started, you need a spark plug socket and ratchet and extension, plus compression gage at Sears $30.00 dollars. Check My Carspace.
#80 of 98 update on stalling problem by hannabanana Oct 07, 2008 (4:02 pm)
I had my brother help me look at the car. We couldn't find any vacuum leaks. He did an old fashioned test of putting a little bit of gas in the air filter to see if the car is getting fuel. Sure enough, the car ran fine until it burned out the gas, and then it stalled. He thought that was a sure sign of a fuel pump problem. We replaced the fuel pump, and it did not fix the problem. It did not seem like there was much or any fuel pressure in the lines. Is there a way to check the pressure in the line? Is it possibly some air flow issue still, even given the fact that it keeps running with gas poured in the air ducts (which seems like fuel delivery to me)? What about EGR or iac valves or mas airflow sensor? These parts are expensive--is there any way to test them? the car is throwing a code, but I don't want to spring a hundred and fifty bucks for the reader unless it will tell me exactly what is going on.

Replying to: hannabanana (Oct 07, 2008 4:02 pm) Is the fuel pump turning on, and pumping fuel? Does it have electrical power?
#82 of 98 reply on fuel pump by hannabanana Oct 07, 2008 (6:32 pm)
yes, the fuel pump turns on (I can hear it), so it's not the fuse or electrical. Now, I don't know if the pump is actually pumping or if the fuel filter is allowing fuel to get pumped. Replies to this message: rearwheeldrive (Oct 10, 2008 1:13 pm)

Replying to: hannabanana (Oct 07, 2008 6:32 pm) If the air duct from the air filter has a crack, it screws up the mass air flow sensor readings and runs poorly.    I'd remove it and look under it for a crack along a seam on one of the ribs. A squeeze test of this duct while running, will cause it to stall out.    Dont buy a Mass Air Sensor till your sure it is bad. I bet if you disconnect the Mass Air Flow sensor it will still run. Some cars computers go into default and will still run on the default settings if it senses a malfunction in the Mass Air Flow Sensor.
#84 of 98 MPG on a 2007 V6 XLE Camry by djm2 Oct 17, 2008 (4:01 am)
Good Morning All:          I just returned from a road trip to New York State. I traveled at 70mph on the NYSTW, and the vehicle got 31mpg! ---- This was achieved on 87 off-brand fuel. ---This is OUTSTANDING for a V6 engine.          On entering the highway from a rest stop, I accelerated "hard" to see how this vehicle would perform. Within seconds it reached 80mph! ----- The shifts were smooth and positive. (The vehicle peformed like a "ROCKET"!) This vehicle could easily cruise at 100mph! (I would love to try this for about 1/2 hour somewhere if "RADAR" was not an issue !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!)--------- It is truly a road car! --- (Life was more fun years ago without road radar.)         Best regards! ------------------- Dwayne
