My 2003 chevy cavelier with 2.2 econo engine cranking the engine all pullies are moving i smell fuel but there is no kick over? start it when key is set back i hear a buzzing clicking electric noise

cranks ok, but will not start
well he low voltage (non told) is from cranking the battery flat/low.
so charge the battery ;.
P0303 codes right? and no others?
power to the fuel pump happens only 3 ways
1: the priming action to pump key on for 1 to 2 seconds, as you can see that is a 2 person job. lacking huge long meter test leadss
2 cranking the pump runs only cranked.
3: engine running.,fully and sustained.
No engine told 3.4L or 3.8L. automatic I resume.
VIN derivative (1) for 3100 LG8 and 3400 LA1
Learn first that injectors are disabled if the pCM sees gross errors with spark, dead cmp , dead ckp or spark feed back dead.
to see that on a scan tool (real)
we use charged battery first.
then scan tool connected we crank for 10 full seconds , no longer.
release the key , not tuned off and see all DTC P03xx not just one.
see them all, and they all matter.
Lacking those events test all spark plugs for spark not just 1.
and test fuel pressure CRANKED a dead engine.
spec is, 3.4L (52-59?psi)

HAVE YOU CHECKED FOR SPARK?

Does it have spark at the spark plug's ?

Check if you are getting spark .

if it is a 2,4 dual over cam enginge it is the coil pack shorting out and it needs replaced

I believe it has a PassKey type of module that requires the correct key inserted in the ignition key cylinder before it will start. It is extremely difficult to disable it, but you may be able to figure out a way with the wiring diagram for the truck (check a service manual or try Alldatadiy.com).

check to make sure the belt is on the crank pully as its the crank pully that turns the belt, the crank pully is the pully at the bottom of the engine normaly the biggest

there are two bolts located behind the pully on the mounting bracket arm, (you have to use a 1/2 inch drive bar in the idler pully to move it so you can see the bolts) That will help you with locating the bolts, while you are moving the pully you might as well take the belt off to save time, After you remove the old idler pully install the new one, use your 1/2 drive bar on the pully to put your belt back on. Pretty simple job, good luck!

where is the fuel pump located on a 2003 chevy malibu ls?
