Hey guys,

My wife's 2000 V-6 Mustang will not start right away when it is cold. It cranks well so I am confident the start is fine, and it will start after a while. The battery is strong since I am able to crank it a few times now problem.

I am not familiar with mustangs, but I am thinking there is so sort of fuel/air problem. I would greatly appreciate any help!

Thanks guys!

well im not expert .....realy im not....but my idea(s) are....

if it wont crank/turn over/ has a hard time with starting and starting to crank but it starts after a while it can be....

like you said a fule/air problem
fuel not "reaching" the fuel injectors (just might take a second or two)
if its not reaching the fuel injectors check the fuel injectors them selves, fuel lines and fuel pump.
defective or aging or just flat out bad spark plugs.
fuel injector or engine contol system malfunction.
distributor box(as i call it, it can be called manydiff things) may be malfunctioning....at first
or again air is just taking its time reaching the the filter and going threw.
*incorrectly gapped spark plugges*

if the engine rotates but will not start...............
#1 reason ....low cylinder compression (ok mabey not #1 but its up there)
again fualty or clogged fuel injectors/ air filter/fuel pump/fuel lines
*incorrectly gapped spark plugges*
wet/damages ignition coils
damaged or disconnected (even loose) crank shaft position sensor
broken/loose/ or disconnected wires in starting circuit
timing chain/belt failure or wearing affecting the valve timing


again it could be anything and thats all i could think of may be slightly off on some of my thoughts


and again i could of missed somthing but thats a;; i could come up with

let me know how it goes...oh and even if the battery is new or you think its good make sure it holding a charge/ the altinator isnt working, or if the cables hooked up to the batter ( + , -) are hooked on all the way and correctly...

good lucky let me know if u have any more questions....if u want

Thanks, I will check those.

Do you know if this car has a extra fuel pump for starting?

If it starts when it's warm and runs OK after it is warmed up then it's probably nothing major.

Possibly a temperature sensor. There is one for the coolant and one for the intake air temperature.

A partially clogged fuel filter can cause problems like this.

Of course new spark plugs may help, but if it starts when it is warm and runs OK after
it warms up thats probably not the main problem.

does the check engine light up? If so go to autozone and have the code pulled and report back. If not no idea.

 

[Bijan77]

Yea the light has been coming on and off. Would the temperature sensors set off the check engine light if faulty?

And the car runs excellent once it is up and running.

Put a fuel psi gauge on it. Should build up psi when you turn on the key 40 to 45 psi and hold it for a while. Then start it if you can and see if the fuel psi is steady even under a load.

ya i kinda just listed some reasons i didnt real read the question completly so i juat started listing....haha...ah well ya they have a better point

my buddy was restoring an ol 1969 mustang and he had just dropped a brand new engine in it (i think...i think its was a v8 cobra engine, but anyways) he got it hooked up to everything went to start it and it wouldnt turn/attempted to start, and come to think of it after checking the hole engine over again and again. the porblem was simple..... the air filter in combination with a cracked spark plugg caused it not to start.........

My 2000 GT has the same problem...actually now it won't start at all. I have changed the fuel filter, and since I am the 3rd owner I can assume it was never changed before, it looked like liquid rust was running through my fuel lines. Can anyone that has changed one on a 2000 GT answer this part: After the connector (to the fuel pump) and the copper tube, there is a rubber hose then another copper tube; I know I pinched, pulled hard, basically kicked that rubber hose part, until I realized I needed a push connect release tool, could I have pinched an unseen copper tube inside the rubber hose?

Like I said, car still won't start...engine cranks and sounds like it just about wants to turn over, but it falls short. Had battery checked, and used a spare fully charged battery; still no start...changed spark plugs, again looks like in 71K miles they hadn't been changed, how it even got a spark before is unbelievable...still engine rotates but won't start. Changed the air filter, even though it was mildly dirty and checked to make sure there was no cracks in the hosing, and that all hoses were connected, etc.

I've tried to hear the whir from the fuel pump to see if that's it, but I hear a few clicks when the ignition is turned to on...don't know if I should be listening under the hood or at the gas tank for the fuel pump pressuring the system.

I don't know enough about the fuel injectors to know if there is something wrong with them either. So any help would be appreciated.

Thanks.

I had the same problem with my '00....Changed the fuel pump and have not had a single problem since then

 

[AZGTConv]

LOL...that's what I was worried about, I have changed one in my jeep Cherokee before and had no problem; but I didn't really want to have to drain the tank and drop it. Actually if you saw the spark plugs, changing the fuel pump will probably be easier than anything else I've done. Thanks for the advise.

Whats wrong with the spark plugs?

And the fuel pump isn't that hard to change....just siphon out some of the fuel before, drop it, and replace

Nothing now, I did a tune up at the same time to make sure that nothing else was wrong, the spark plugs were basically welded in the engine (I just bought it about 8 months ago and hadn't started doing anything to it); I had to let them soak for 2 hours after finally breaking them loose. Once out they looked like they had never been changed in 9 years, with only 71,000 miles on it I'd have thought someone would have loved the car enough to at least take it in for service once, but I'm finding out that that probably wasn't the case.

No, I know changing the fuel pump isn't hard, but I have to work this weekend and since I just started rebuilding the engine in my other car (of course my GT would die after I got the other engine out) to fix a blown head gasket, I won't have much sunlight to work on the GT until Monday and I was hoping it would be something less time consuming. So I was really just complaining, then and now...lol.

Thanks for putting me back in perspective, and reminding me that I work on my own cars because I don't have any Navy Hornets here at DM to work on. hsnap

Ah i see...damn 71k miles without a change is rough :lol


You work on F/A-18's? Thats awesome!

Not at the moment...right now I'm on my admin tour, hence ending up at an AFB with a bunch of other Navy/Marines, unfortunately alot of our admin tours are now at Reserve Centers administrating for reservists; but I'll go back to a squadron in 2011. What do you do up there at Luke?

Hey man im having the same problem with my 02 once it gets cold she just doesnt want to start

Hey man im having the same problem with my 02 once it gets cold she just doesnt want to start

Like i said above...I was having the EXACT same problem. At first it wouldn't start when the weather was cold...then eventually it got bad enough to where it wouldn't start no matter how hot/cold...It was the fuel pump going bad
