Smell of Gas
 

Hello and happy holidays to all

Recently(just before Christmas) I started to smell gas after driving it and parking. It goes away after a while but I am afraid that I have a leak someplace. I just read in this forum that there is a known problem with the spider injection system in the 4.3 V6. My question is. would a problem like this throw a code(CES light) be on, because there is no light on and no codes being active.

Just wondering thanks in advance

The fuel delivery system is not monitored by the OBDII system so it can't set a code or turn the light on. Checking fuel pressure and leakdown at the service port will tell if there is a leak in the pressure side of the system, not the return line.

Follow the instruction for testing at the service port and leakdown, in this link: https://blazerforum.com/forum/2nd-ge...eakdown-88305/

Post your results.

Thank you Captain Hook..good to know

Happy New Year
