Hello again,
My 99 Sonata (2.5 V6) has a problem... It is taking way to long to start it....It cranks normally but it takes a good 5-10 seconds to start. Once it starts, it runs fine (no stumbling, etc...)
I checked the fuel supply at the return on the regulator (took off the return line, and cranked a little, and gas came out of the rail through the regulator... So I guess I'm getting gas.
When I bought the car, the dealer told me they had to replace some things before they sold it to me 3/05 and I think he said he replaced the plugs & wires.
I pulled the front 3 plugs to examine (By the way, I have good spark thru the wires) The plugs look as though they have 50k miles on them (Champion plugs). The plugs were black, and had carbon build-up on the ends of the plugs, also carbon/oil buildup around the threads. The wires looked ok, but not like they had only 6k miles on them (That's how much I put on since buying it in March)
The car acts like it is flooding, why isn't it firing?... If I push the gas pedal all the way down while starting, it seems to help start quicker...
What else can I check out? Air filter is clean...PCV valve may be? Also the oil cap closes, but has up, and down loose movement. Should I change the plugs and wires first?
THANKS
