I think my FPR is pushing too much fuel into the car under cold start-up. This makes a strong fuel smell that goes away in a few minutes when the car warms up. It seems to also happen under repeated heavy acceleration. Where is it located in the engine area?

Anyone else have the same issue?

Thanks.

Paul

PS the car is a 2003 STR with 90k miles

 

Hi Paul, and welcome. The STR doesn't use a fuel pressure regulator. Check for problem codes.

 

You might like to read the fuel trims.

I doubt it's anything remotely like what you've guessed.

Is it definitely a fuel smell or exhaust smell? Also, where do you smell it? If in the cabin, how (where) is it coming in? You may need a passenger to sniff as you boot it and get them to sit in front and back.

edit: if you like, you could read the actual fuel pressure and compare with the car's fuel pressure sensor. I'd pursue the leak instead

A possible suggestion is to start on the passengers side of the engine. Gently pull up the portion of the wiring loom that sits over the rocker box and next to the S/C cooler tank. This will give you much better line of sight to the fuel rail.

With the engine ticking over look at the mushroom headed protrusion that hangs down from the fuel rail. There is a high probability that this is leaking and running back down the engine and dripping out onto the bell-housing before evaporating.

As this is close to the intake for the HVAC system the smell of raw fuel is more prominent and your symptoms indicate a leak in this area to me. If this is a recent event there may not be any codes set but worth checking for any in pending.

As always with any fuel leak take safety seriously and be cautious searching to resolve it quickly

I hope this is possibly of some assistance.

 

Thank you everyone for the help. I will check on those items. We did plug it into a machine and there were no codes.

 

Don't know if this would help:
