Question about 2003 Pontiac Grand Am

1 Answer

I have a 2003 Grand Am GT and the engine just turns over

It`s a V6 3400sfi. The engine just spins like it wants to start. Tried spraying it with starter fluid but that did nothing. Tank is on half. Was wondering if it`s the timing chain, fuel pump, or maybe the coil pack?

I would have someone turn the key to the on position and listen to see if you hear the fuel pump whinnig ( means it is building pressure). Then if that is good then i would take a spark plug wire off and see if you are getting fire from the plug!! what caused it to jus stop running for??

98 Pontiac Grand Prix load front end roaring?


Defective fan clutch, if it has one. With a cold engine only, try spinning the fan blade by hand. If it does not turn freely, the fan clutch is defective. Warning: When the engine is hot, the fan can turn on by itself with the car not running and keys are NOT in the ignition.

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.

2003 Grand Jeep Cherokee will not start.


Could be a faulty starter or bad connection between the battery and starter. You could use a meter to check for voltage at the starter but it will not show resistance in the cables.

2003 pontiac grand am gt....'track off" light is on..what does that mean?


it means that you're traction control is disabled. You are now able to spin tires/burn out. If you do not want to do that, locate the button to turn it back on... usually it just says TRAC on the button, usuallly located towards the bottom of the dash.

2003 Pontiac Grand Prix SE 6 Cyl - Cooling Fan Not Operating


the fan motor could just be bad, you can test this by removing the fan and connecting a wire to each terminal and to a battery. the wires hooked up one way will spin the fan and the other way will spin the fan backwards so you cant hook it up wrong. I hope that helps you out!
