What would cause plugs to be wet with gas after sitting over night?


Asked by Mar 14, 2016 at 11:31 AM about the 1996 Honda Accord EX

Question type: Maintenance & Repair

1996 Honda accord  plugs are wet with gas after sitting over night. I replaced injectors and didn't help. Replaced the fuel pressure regulator with one from a junk yard and it ran great for about a month then had same issue. I replaced it again with another used one and it ran great for a few weeks. I replaced it again with a new one and it ran great for two weeks. It has spark. If I clean the plugs and replace them it will start. Any suggestions?

Better test the fuel pump, if it making too much pressure it can blow regulators, injectors, high pressure hoses, etc.


Fuel pump tested fine. New injectors, new fuel filter, plugs and wires


Then check the regulator for fuel leaking back through the vacuum hose.


The car will run great all day but after sitting for a few hours it starts rough then smooth's out. I'll pull the plugs and they are wet with gas but only after sitting for a while


And your sure it is gas and not coolant. If it is fuel I would start by disconnecting vacuum hoses that could possibly have fuel in them when your ready to shut it down, like the regulator hose, vapor canister hose etc. if that becomes a dead end then try electrically disconnecting the injectors and let it sit there has to be a leak somewhere.


Vacuum lines are dry. New fuel pressure regulator. I was fine when I first replaced it then it started again. Is there something to cause the FPR to malfunction?


The only thing I can think of is if the engine pops back through the intake, if there was enough force it could rupture the diaphragm but then there would be fuel in the vacuum line if that happened. Did you try electrical disconnecting the injectors yet?
