fuel flowing from air intake
1990 ZR1: Started engine but after about 2 minutes it stalled. Tried to restart but no luck. Smelled gas and found large puddle at front of car. Removed air filter and found large amount of fuel coming out of the plenum. Any suggestions? Please?

Re: fuel flowing from air intake
Fuel pressure regulator might be bad or stuck injector pull the spark plugs out to purge out the raw gas so you dont bend a valve

Re: fuel flowing from air intake
When that happened to my car it was the fuel pressure regulator, leaking.

Re: fuel flowing from air intake
Thanks for the info. I'll try the pressure regulator first. Anybody else seen this happen?

Re: fuel flowing from air intake
I had a similar issue. Turned out to be the fuel pressure regulator also.

Re: fuel flowing from air intake
Hi,
I see two part numbers: 1990 to 1992 is 17112220 1993 to 1995 is 17069632 Are they interchangeable? Thanks, Bill

Re: fuel flowing from air intake
Is there any way to replace the diaphragm in the regulator?
That's pretty much the only part in them that could go bad... |
