Replying to: chevymalibu (May 16, 2006 2:46 am) No, the Camry cannot use this fuel, including the newest models. It says in the 2004-05 manuals that gasoline containing up to 10% ethanol can be used.
#45 of 98 fuel pump prime by penizzle Jul 08, 2006 (8:20 am)
Is my 04' camry supposed to have a fuel pump prime, because on all of my other cars it primes but not this one, but it does run good. If you turn the Ignition to the ON position, do you hear a small whiring from the back of the car for a few seconds. Im confused becasue according to my manual, to check fuel pressure you have to have the prime. ANYBODY CHECk for your prime, regarless of year. Although i have a 93 but it isnt suposed to.

Replying to: penizzle (Jul 08, 2006 8:20 am) Yes,the noise is the fuel pump. Fuel injected cars will prime when the key is turned on.Why are you concerned with fuel pump pressure if there is nothing wrong with the way the car is running?

Replying to: typesix (Jul 09, 2006 12:23 pm) Perhaps you dont understant. My camry doesnt have the prime. Every year, my manual suggests checking fuel pressure and to do that, i need the prime according to the manual. I know enough about cars to the point where i know what is going on.

Replying to: penizzle (Jul 10, 2006 7:33 am) At the risk of alienating you (and no one is implying you're not knowledgeable), if your fuel pump wasn't able to achieve prime when the ignition switch is turned on, your engine wouldn't run at all. There has to be a minimally nominal 32-35 psi for the injectors to work. Whether you can actually hear the brief groan in the cabin as the fuel pressure spools up may be related to your own hearing abilities depending on age, prior illness, etc. You might try removing the fuel filler cap and remaining close by the open fill tube while someone else turns on the ignition switch from the driver's seat. (ONLY attempt this procedure in open air!) By having more immediate access to the noise the fuel pump makes in operation, you may be able to verify the fuel pump priming up to nominal pressure. Regardless, if you can start and drive the car, the fuel pump has achieved prime. Replies to this message: penizzle (Jul 10, 2006 4:15 pm)

Replying to: ray_h1 (Jul 10, 2006 3:53 pm) I guaruntee that my hearing isn't bad. I'm only 15. The system only pressurizes when the pump recieves cranking signals from the engine to the PCM, so depending on the set of of your PCM, it may prime or it may not, but if there is no prime, it can still start because MPFI vehicles dont lose all fuel pressure when not running. Yes this is weird to hear from a 15 year old, but i am a car nut. But now i realize, who cares?? THe car runs and that is all that matters.
#50 of 98 Slow Fill up by jpclan Aug 20, 2006 (2:24 pm)
I have a '98 Toyota Camry and we can't figure this one out. Filling up the car takes forever because the pump keeps cutting off. No matter where we fill up this happens. Always thought the cut off was a function of back pressure from the tank, but this happens all the time no matter how we manipulate the pump. Any ideas?

Replying to: jpclan (Aug 20, 2006 2:24 pm) Check for a damaged fill pipe as it could be kinked allowing slow fuel fillup. The fill pipe is the large blck pipe that goes from the place ou put gas in to the side of the fuel tank Easy replacement if that is the problem.

Replying to: jpclan (Aug 20, 2006 2:24 pm) or there is a vent valve and reclaimation filter assembly. it could be the vent valve is not working properly, or the vent line is kinked.   as penizzle is describing, anything which prevents displacement of the air in the tank when the fuel is going in will build a back pressure as you said causing it to be sensed in the pump nozzle and cause the pump to stop.   the place to start is the filler tube as was mentioned. if it isn't that, then i've provided what i think is the other most likely possibility.   on some cars, i think they have an internal bladder in the fuel tank. possibly if you run them too low, it's a problem to get them to open/expand back out. not sure about that, but i don't think you're vehicle has that sort of thing.
#53 of 98 Help!!!!! by bigman07 Aug 24, 2006 (3:21 pm)
Replying to: grant2 (Aug 20, 2005 9:03 pm) I have a big problem and I want either of you to either email me the problem back or post it in the room...ok   I was driving my car down the street to a friend's Home and all of a sudden it stopped in front of the road,so one of my buddy's mechanic friend checked it out for me,to see what was wrong and he didnt know the problem.this is what happened... I started to crank it up just to see will it start but no results, my mechanic looked inside the engine into one of the spark plugs to our surprise.. gas drowned out the spark plugs leaving it black ... the question is, if you crank your ride and gas shoots inside your spark plugs and drowns them everytime what could be the problem.. i need a answer ASAP.. Please!!! Replies to this message: penizzle (Aug 31, 2006 2:50 am)
