2003 Dodge grand caravan won't start gas coming from the spark plugs


If spark plugs are fuel fouled, the engine is flooded. It can be flooded for several reasons. No spark to the spark plugs is the most likely cause. However, a stuck injector or defective fuel pressure regulator can also contribute to this situation. Check and make sure there is spark to the spark plugs

Spark plugs flooding


lets back up here fellas. a lot of crazy rabbit holes we have gone down. spark plugs dont get "flooded" with fuel, they do however show signs of being wet due to an oil leak up the threads. is this what is the problem, do you smell fuel and oil when you remove them?

I have a 1993 ford econoline E150 tht won't stay running


id do the 60k mile tune up first.
then if still bad.
find out if the problem is spark (test spark)
or bad fueling, check for flooding at any spark plug.
if not flooding (spark tips , read) then try test fuel.

if flooded try super secret unflood mode,
that is crank with wide open throttle.
if ISC is stuck closed, try cranking with 10% throttle (adds the missing air)

95 trooper flooding cylinders when cranking, runs great when starts,but setting all day or night, floods again, will run then if spark plugs removed & cleaned!!, all sensors changed!! WHAT TO DO NEXT??...


Connect a fuel pressure gauge to the fuel line and check the fuel pressure. If it exceeds manufacturers specifications; replace the fuel pressure regulator.
Spark plug cables which have aged, and now have more han 1,000 ohms resistance per inch of length, also can lead to cylinder flooding; and should be replaced.

2003 Suzuki Grand Vitara won't start engine


what engine, state engine size and country.
there can only be 3 ways, to fail.
bad engine (low compresssion, us the $20 tool at WOT and see over 170psi.
Bad spark
bad fueling.
just because spark coils (COPS?) work on other car , dont mean much.
what counts is your car , its a system.
the cops, have fast 5mS pulse when firing, you using a scope to see that?
Im so curious, why not to the time old test, use a real spark plug
attached to the COP end, spark plug shell grounded to engine metal
and crank, is spark good x4? or x6 if V6 (engine NOT STATED)
is it? then spark is good, leaving fueling.
do not touch the spark plug cranking, it can hit 100,000 volts.
I use a ground strap on the spark plug casing, hands free, or you can be hurt bad, by the spark or when you jump and cut arm backing off
on cars that flood, is it flooding?
I found my engine compression good, then found all 4 sparks fire good.
so i pull the fuel pump relay. killing fueling.
i then use "test fuel" to start engine (again, text book tests)
I use the new CRC brand of test fuel with top end oiling.
i spray it in the plenum, and it starts.
if the spark plugs are bad, (part oftune it up)
it may not start if flooded,
use WOT at the throttle (cuts fuel) and start any flooded engine.
if the spark tips are black and stink of raw fuel (wet with fuel)
that means flooding.
pull the fuel pump relay ,test fuel runs for 3 seconds. each time.
3 second spray max. each time.
if that works out, then find reason for flooding if flooding.
if not flooding, you find dry sparks.
then trouble shoot no fuel.
fuel pressure not near 30 PS?
fuel pressure too high say, 60, it will flood for ever.
there are only 3 tests.
and 4 counting wet /dry sparks.
the tests done, will put you on the correct path every time.
no guessing, no swapping parts to other cars.

As mentioned by you the fuel discharge is too much which seems to FLOOD the cylinders and so makes the firing difficult. So the fuel tuning must be done to ensure the correct pressure.
Also check if the spark intensity is good as if there is no spark there will be fuel flooding.
Have the fuel pump calibrated and the injectors checked, if not replace.

If I read it right then you have flood of Fuel. Have you check all the spark plugs to see all the same wetness. You have not mentioned spark plugs replacement, so I assumed that you have strong spark. Therefore I conclude your problem is the Fuel distributor. Hope it can help?

Verify you have good strong spark at the plugs. Also you want to check the fuel pressure with a gauge. If it's within specs and you have good spark, it could be flooded. Once in a while these trucks will flood the plugs if the secondary ignition has not been replaced in a while. Try starting the truck with the throttle wide open (clear flood mode) and see if it fires. If not, look at the plugs and replace as needed.
