1999 Lincoln Continental Repair Question
Gas ordor/hard starting 99 Cont
inspect fuel rail crossover hose
the odor is under the car in the rear. Isn't this part in the engine compartment? I see it was a recall item.
any codes related to the evap system
canister vent solenoid ?
no codes. had fuel line pressure tested yesterday. it does lose pressure when sitting. technician said probably bad fuel pump but if so , why do I get the odor? seems like it should be in one of the lines but I never get any visible fuel under the car.
With out codes its must more difficult
If have a good fuel pressure I would not suspect a fuel pump is its not the cause of a fuel smell
Have to try and pin point the area of the leak or the area where the smell is strongest
Separate the fittings.
Inspect for damage.
Clean the fittings
The evaporative emission system job is to:
Prevents hydrocarbon emissions from reaching the atmosphere.
Stores fuel vapors in the evaporative emissions (EVAP) canister that are generated during vehicle operation or hot soak, or vehicle refueling, until they can be consumed by the engine during normal engine operation.
Routes the stored fuel vapors to the engine during engine operation.
1 9F980 Evaporative emission (EVAP) test port
2 9C915 EVAP canister purge valve
3 9C052 Inline fuel tank pressure (FTP) sensor (part of fuel vapor control valve tube assembly)
4 9C047 Fuel vapor control valve tube assembly
5 9F945 Canister vent solenoid
6 9E857 Evaporative emission canister with bracket assembly
THANKS, THE LEAK MUST BE ON THE PRESSURE SIDE OF THE LINE SINCE IT IS HARD TO START AFTER IT HAS BEEN SITTING. I SUSPECT THAT IT MUST BE THE TUBE COMING OUT OF THE GAS TANK AND TO THE FUEL FILTER. THAT WAS REPLACED A MONTH AGO AND "FIXED" THE PROBLEM FOR 2 WEEKS. I THINK IT MUST HAVE NOT BEEN A GOOD INSTALLATION. THAT AREA IS WHERE THE SMELL IS AND THERE IS NO OTHER EVIDENCE OF LEAK ANYWHERE ELSE. SINCE THE TUBE IS ON TOP OF THE TANK, IF THERE IS A LEAK IT MIGHT NOT BE VISIBLE. GOING TO THIRD MECHANIC NEXT WEEK SINCE THE DEALER WHO FIXED IT ORIGINALLY WANTS TO FOCUS ON BAD TANK/FUEL PUMP.
Leak may not be large to be visible and fuel is vaporizing and not leaking down to be noticed under the car
A bad or unsealed line very possible
Dropping the fuel tank I think should reveal the leak
thanks for your help. FYI finally a mechanic found the problem. it is a crack in the plastic elbow coming out of the fuel pump. since it on top of the tank there are fumes but no visible gas. most people thought that if the leak were on the pressure side gas would squirt out but I guess since this elbow is on the very top of the line only a little liquid comes out and evaporates. the original fix which was replacing the line going to this elbow may have temporarily covered the crack. hope this is helpful in the future
Thank you for your follow up information. It really does help when you provide the solution so others can benefit as well. Have a great day.
