It's hard to start and loss of power and putting and stalls, already did fuel filter, cam censor, plugs,coils. Someone please help me
The I6 4.2 from 2002-2009 has throttle body issues, must be cleaned. Fuel smell is unfortunately common, but can be several things. First thing I'd check though is the fuel regulator located on the passengers side just below the Vortec plastic box in the middle. This is the most common one for a fuel smell. Other problem locations are at the gas filler neck or fuel tank.
What year ? Is it 4.3 V6 ? The 4.3 had injector units and regulators that were prone to leak .
SOURCE: hard to start and smell gas
have 1994 4.3 cpi and the problem I had sounds same.
It was a leaky pressure line in pletium . easy fix $45.00 part $15.00 gasket.
the leak was caused from the fuel lines rubbing together in pletium.
take the vortec cover off ,then remove air regulator in middle and look inside . I turned on power to key and gas spray came from drivers side of pletium looking in hole.fuel line side. if gas spray on passanger side then gas regulator faulty. takes 5 min to check
After fixing truck runs runs great. no more gas smell in cab.
also you can smell oil for gas
Not terribly familliar with honda cars but most systems use either a cold start injector or just richen up mixture through the normal fuel system. This is controlled by a temperature sensor, either separate from or part of dash gauge sensor. I'd begin looking for that. If its always in "cold start" if will give you symptoms like yours. If not fuel injected, check choke operation. This may not be a "cure" but it's a good place to begin looking!
Check for a good spark at the plugs ,if ok check fuel pressure and fuel flow. fuel pressure should be around 300 kpa, Flow around 500 ml, in 30 seconds.
