#101 of 116 Avalon Starting Problem
by bigroz8000
Apr 20, 2010 (6:52 am)
Hello. I have a 2002 Toyota Avalon with 103,000 miles. Car is running fine and starts fine on a daily basis. But, if I have to start and restart the car several times in short period of time, it will sometimes have problems starting. It will always crank and turn over but, the engine will not idle very strong and then it will just die. This only occurs if I have to make a lot stops and need to restart the engine several times in a short period of time. It starts fine if the engine is cold. Any ideas what might be causing this? I appreciate any and all responses. Thanks for you help.

I'd certainly have the fuel pressure regulator looked at. Sometimes you can test this yourself by pulling off the vacuum line that regulates it---if that line has fuel in it that dribbles out, or if it dribbles out of the regulator, it's toast. What happens is that the fuel pressure in your fuel line bleeds off as the car sits, requiring the fuel pump to re-pressurize the entire fuel system every time you start.
#103 of 116 problems starting and won't stay running

Recently put a new motor in my 95 toyota avalon. The car won't start on the first try. On the second try it will start but won't stay running. Have to keep starting about six or seven times in order to stay running. Once it stays running and you put it in drive and step on the gas it just seems like it won't take its gas. The tach will go up but the speedometer doesn't. When you step on the gas the car will bog out; let off the gas and it will pick it up some. It does not do this when the car is in reverse. Any suggestions.
#104 of 116 96 Avalon starting trouble and gear shifter

Hello,
I'm writing this on behalf of my grandparents and their 1996 Avalon that has 30k miles on it. It has recently been serviced for fluids and the battery has been tested. The problem as described to me is that sometimes, not every time, Grandpa tries to start the car there is dead silence. No clicks or turning of the starter. Then after some fiddling it starts up. He tells me that when he has this problem he has to push in on the shifter (not sure if there is a button or if he is just pushing it up further in gear or something similar), and when he gets the right spot, it will crank and usually turn over. He thinks alternator/battery are both fine. Anyone have any clue what else we can look into before bringing it in to the service shop? One local mechanic already looked at it and was puzzled by the description and was unable to duplicate the problem when he was looking at it.
Thanks very much!
#105 of 116 problem starting 2000 avalon xls with 3.0 liter

Please bear with me. The water pump in my 2000 Avalon XLS (3.0 liter) DOHC went and was changed. A friend of mine is a mechanic and he has a garage and he changed it. I was in attendance whie he was putting it back together. Okay so he set the timing (new timing belt was installed too). He turned the crank manually to make sure that there wasn't any obstructio9ns with the valves and pistons cause he caims this motor is an interference motor, although I have now read otherwise. After that checked out OK we started the car to make sure timing was ok before reassembling everything. Car fired right up without any hesitation. So we started putting everything back together (hosing for motor mount tower, all covers, belts etc etc). We fired it up one more time and it fired up no problem. Then we added the water and antifreeze with a burp tank. Got everything all back together and started the car, it needed to be jumped cause the battery was weak. Car started withiout hesitation once again. There was a rubbing noise(kinda loud) so he looked down and noticed that the crank timing belt sprocket was rubbing on the cover. You could actually see the sprocket a little as it had rubbed through. So brillianly he decides he is going to just snap off the part of the cover that is rubbing rather than taking it back apart and fixing it correctly. So he breaks off pieces and gets enough off so it won't rub. To access this he had to loosen tho upper motor mount and the bolts that connect it to the motor. One of these bolts also has a ground connected to it and at this point the groung was off. He told me to start it to make sure it wasn't rubbing (I didn't realize that the ground wasn't hooked up) So the car started fine but immediately shut down within a second or two. There wasn't any sputtering or anythisg. I did notice the dash lights were real dim when it started (It had to be jump to start this time too). So we tightened everything back up and tried to start it and now it will not start. Gas was low so we added gas but still didn't start. Now I am wondering if that ground not being hooked up fried something or bvlew a fuse. But we checked the sparkplugs and the cylinder in fronmt on the passenger side is getting spark. So my question is where do I go from here. He looked at the spark plugs and there was a little gunjk on them and hes trying to say the head gasket is gone. I know enough about cars to know that is not the reasson it wont start. It started fine 4 times prior. I feel like he is trying to use that as a cop out because he knows he made a boo boo when he told me to start it without th ground hooked up. I am wondering if a piece of the cover he snapped off fell back on the crank timing sprocket and made the belt jump a few teeth when we started it. Because thats how it acted it started then just cut straight off, no sputtering just straight off like the timing slipped. I would take any advice possible please and could someone tell me if this 3.0 liter DOHC is an intererence motor in which the valves and pistons could collide if the timing was off.

1999 Avalon will not start - as in battery failure; however, when one plays with the ignition key for a while it will. Is there a common problem with the security system?
#107 of 116 cranks cranks...then starts

2001 Toyota Avalon XLS, 58,0000 miles. I'm new to this site and this is my first post so I'll start from the beginning... I went to start my car and all it will do is crank, startled by this I put the key to the on position and waited for the dinging (those dinging sounds for putting seat belt on) to stop and then the car started right up. I then just recently tried starting the car without waiting for the dinging to stop and it just cranks and cranks about the same amount of time for the dinging to stop and it will fire right up. So this is telling me it has something to do with the time lapse for something to open or happen, but what? I'm getting ready to make a 1800 mile trip by myself and worried about getting stranded. And I also don't have the $ to spend on a lot of diagnosis testing that I'm hearing from auto shops when I called yesterday. Please after reading so many helpful posts, I'm hoping someone will have an idea of what is happening. Thank you.

First wild guess: weak fuel pump. The time is the delay in building up pressure in the line to supply fuel at the right pressure to the engine. Possibly a partly blocked fuel line also.
Second wild guess: Electrical, some type of coil failure...but that's not my area, so... others will need to help here.
This is a 10 year old car, anything is possible... but something is going wrong as you cannot start the car normally. Hope this helps.....

Are you referring to cold starts? Probably the idle control valve. If this happens when the engine is warm, the idle control valve is still a possibility, but less so.
