i have a 2002 dodge caravan 2.4 engine, it floods every time i start it when its cold. Just replaced the timing belt, spark plugs, wires , water pump. any help ?
Check your vacuum lines and make sure they are all good. You may have low voltage in your battery. There's a decent chance that the engine is just flooded due to the low battery voltage. Fuel is dispensed according to intake manifold vacuum and if you have little to no vacuum from low cranking speeds, the engine may become overfueled and flooded. Try charging battery over night. With good cranking speed restored, plant the throttle to the floor and crank it for at least ten seconds continuously or until it fires. Wide open throttle during engine cranking will employ the clear-flood feature of your fuel system, which turns the injectors off and allows the engine to clear any excess fuel. The wide open throttle blade speeds the process by flushing the engine with fresh air. Once it starts and runs... you're done! But if it won't go, try the code- read feature it's something that lets you read codes without a scan tool. Roll the key from off to on three times (leave ON) and watch the odometer window for code display. The last thing shown will be "done" once completed whether codes were present or not.
