noticed usually right when i start my car i get a strong smell of fuel . cant tell where to pin point bt smell from engine and under car? anybody know what can cause this?
98 accord v6

 

Is it only when you turn the key to II(ON)?
If so, there may be a fuel leak. When you turn the car 'ON' the fuel system pressurizes.
Might also be a faulty EVAP valve that is incorrectly venting fuel vapor to atmosphere, or a vacuum leak in the EVAP system, which may be part of your revv issue.

 

not sure just noticed when i start my car. havent really tried any troubleshooting didnt know where to start. how should i go about trying to pinpoint the issue? okay to drive?

 

no check engine light

 

Pop the hood, look at all the fuel related hoses, have someone turn the car to ON and look for any wetness around the injectors/fuel lines/filter/FPR/ etc.

Try and pin point the smells origin.
If it does it at every start it may be fairly easy to find.

 

okay thanks ill give that a try

 

Can you tell if it coming from the front or back of car?

 

front of car. to me smeell more from under car but still linda smells around engine

 

look closely at the fuel rail and fuel filter after priming the fuel pump would be where i would start

 

smelled around injectors rail lines regulator and couldnt smell or see and fuel leaks.. the smell is positively coming from the exhaust. smells pretty strong

 

u might have a dead cylinder ..check your wires

also check your plugs see if one is extra black or all black

 

how can you check if you have a dead cylinder?
yeah iwas planning on changing out the spark plugs anyways cause ijust boight car and doubt theyve been changed out. along with wires and dizzy cap and rotor. what happens if i hve a dead cylinder?

well normally it means there is no compression but it could just one spark plug is bad or a wire is bad or the cap is bad or even an injector isn't firing

I would check all that out but only after i looked at my spark plugs. They should all be tan.

I actually used to smell fuel when my egr system on my camry needed cleaning but it would run rough on start up which is what pointed me in that direction.

 

fasure well hopefully a good tune will take care of it dont really wnt to mess with the fuel system buut will if i have to. ill probably try doing it this weekend.
any advice on all that should be done on a tune up

 

standard ignition tuneup is cap, rotor, plugs ... if oxygen sensor hasnt been replaced in over 75k then its due too but this sounds ignition related

 

if oxygen sensor was faulty i would get a light tho wouldnt i?
if needed changing would both be changed?

 

oxygen sensors rarely throw a code when they go bad .. unless the heating element goes bad

 

i get ya. ill start with the ignition tune up anf go from there. thanks

 

check for stored codes too

 

my back tube seal were fucked and had oil in spark plug tubes.
got em cleaned out and put new ones on. the plugs disnt look too bad just relly white
