my car won't start HELP!!!!
 
my 1st time ever.

I backed the car out the garage and shut it off. About an hr. later I go to take it for a ride and it won't crank. It turns over but doesn't fire. This is what I checked:

all fuses - good
all relays - good
pulled a coil - got spark
pulled an injector wire - got power
check fuel pressure - ~45psi
looked into the oil fill hole - valve train moves
fuel pump reset button - not tripped
PATS - theft light not going crazy
tune - reflased a tune, no changes

WTF can it be??

dead battery? does it click or does the turn over seem faint?

sounds like a dead battery to me

it cranks fine, not even weak at all, just doesn't fire up. BTW I have no codes either.

I did put the battery on a charger since I was cranking on it for a while, even though it is turning over just fine.

But you do have fuel at the rail? If you have a strong crank (and spark) and it just won't fire, it sounds like fuel. Oh and normally went PATS is acting up, nothing happens when you turn the key.

45 psi at the rail and injectors have power so I don't see how it can be fuel. :scratches head:

i guess i dont understand the symptom....does it make a clunk then nothing at all? does it click click click repeatedly? does it sound like its cranking but wont actually fire? sounds like it wants to start but wont? be more descriptive.....

yes and yes

Gummed up fuel injectors?

01GT4.6 Mar 6, 2009 04:26 PM

here is why I'm confused... it has run perfect, never misfire, sputter or hesitation. It fired right up this morning, now it won't start. I'd understand if it would fire up but run like crap, then I'd say it may be an injector, spark plug or something like this. My gut tells me it's electrical... but what could it be?
