I have a 1989 mercury grand marquis and when I turn the key on the fuel pump kicks on (but keeps running) and the car won't start. Any suggestions?


Is car flooding? Leaking injectors. Is car not flooding? Bad fuel pressure regulator, bad fuel pump pressure, leak in system.

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

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.

2000 gtp starts runs good for a min or 2 then dies when i try and start it again it seems flooded with gas


Pull off the vacuum hose to the fuel [pressure regulator (if it's on the fuel rail, and not in the gas tank), and see if any evidence of gas being sucked into the hose (and on into the engine) from a ruptured diaphragm in the regulator. If that's alright, have the fuel system checked for proper pressure. Should be around 40-50 psi. Your car will have a specified pressure to run right.

My 2004 pontiac grand prix will not start on the first or second try.


Would you describe it as it cranks over normally but takes longer to start than normal especially if the engine is hot and sits for about 15 to 20 minutes before trying to start?

The first thing I would check is the fuel pressure regulator. It will be located on the fuel rail on the drivers front of the engine. It will be a round looking part held into the rail with a snap ring. It will have a small vacuum hose attached to it. Remove the vacuum hose and see if gas comes out of the nipple. If it does than the regulator is bad and will need to be replaced.

Two things happen when the regulators leak like this. the first is that fuel pressure drops. Low fuel pressure makes the fuel easier to boil in a hot engine. Fuel injector need liquid fuel to work properly. the other is that unmetered fuel ends up in the intake essentially flooding the engine. In both cases the engine eill need to be cranked over long enough to clear the flooded condition and for the fuel pump to run long enough to push liquid fuel back into the fuuel rail and restore fuel pressure.

Here's a trick to try next time. Turn the key to the run position (do not turn it all the way to the crank position). Wait 5 seconds and turn the key off then imediately turn the key back to the run position and wait another 5 seconds. Repeat this 3 or 4 times then crank the engine over. If it starts right up every time than you definitely have an issue with fuel pressure bleeding off.

The most common cause is a leaking pressure regulator but it can also be the fuel pump.

1992 F150 5.0 flooded


Hi, wow!

sounds bad, I would drain the oil and leave it over night to drip out so it is completely dry, leave all oil caps an anything that will allow air in off the truck.

Do you have a compressor or air line you could use to blast air through the engine. if this is diesel fuel then it will take much longer to evaporate if this is gas/petrol then over night should do it.

Hope this helps

Wont start 1996 jeep grand cherokee laredo inline six4.0 fuel inj


The first thing I would do since you think it was flooded is to replace the sparkplugs, sometimes if a spark plug has been washed out with gas you cannot get it completely dried out. After you replace sparkplugs try to start the engine. If the engine starts I would still recommend that you change your oil because of fuel saturation. If your engine fails to start I would suspect that you have a bad crankshaft position sensor as it is known to give problems. The crankshaft position sensor is located on the top of the transmission bell housing on the drivers side.

Car will not start


If this is a six cylinder, there were problems with the fuel pressure regulator leaking gas into the vacuum line creating a flooded condition. You might want to check map sensor,crank sensor.
