Car wont start

This sound like you have a positive battery cable that is internally corroded and not allowing the current to flow. Please use a test light and check to see if the have 12 volts at the PDC or the large starter lug.

Here is a guide to help you do some testing.

My friends car, which has the 4.0L V6, was running okay as he drove down the highway and it suddenly just stopped running. Now it won't start. Things I checked: 1) Used code reader and it shows no codes. 2) Disconnected fuel line at filter and checked for fuel delivery to that point and it was good. 3) Installed new fuel filter. 4) Checked for spark on at least two spark plug wires and got good spark. 5) Can see thru oil filler cap that drivers side o/h cam is turning and removed valve cover on passenger side and it is turning. 6) Power pack was replaced by a mechanic friend. The engine cranks well and their is a subtle sound of coughing internally.

See if it will start for a couple seconds using starting fluid.

Let me know what you find.

Sprayed start fluid into throttle body. Did not try to run at all. Did you review all the things I've already tried?

If you are certain that it has spark (2 checked) starting fluid should have started it for a couple seconds. Since it didn't, check to make sure all plugs are getting spark, a good hot blue snapping spark. If they all are, suspect a jumped timing belt. I say jumped because you say you can see the cam turning.

Sorry, I meant to say that you can see one cam turning. The chain may have broken or jumped time on the opposite side.

I assume you just made a mistake when you said it might be a "jumped timing belt" as this vehicle has timing chains instead of belt. With that said, one of the things I too suspect is that the car has somehow jumped timing. The coughing internally when I try to start it seems to be a sign that possibly the timing is off. I was able to confirm that both left and right cams are still turning. One by viewing the chain/sprocket through the oil filler hole (driver side) and the other (passenger side) by actually removing the valve cover. So, if it has jumped timing, what test can I perform to confirm?

About 2 weeks ago my car began to not start the first time or two but would afterwards. A few days ago, however it wouldn't start at all! Or crank! The battery is only a few months old so I doubt that's the problem. Any ideas of what it might be and how to fix it?

Yes, I realized I said belt and fixed it on the next post. The only thing you can do is check to see if timing marks line up.

try resetting security system if no manual look online.

I tried it and still no luck. Do you think it might be the starter or somewhere along those lines because when it does choose to start its when I have my foot pressed hard on the clutch?

check see if switch for clutch is sending power through it if it does it may be a fuse box problem where starter relay either has corrosion on the prongs or not making good contact. with out seeing I have no other answer.

car studders when trying to start and it wont start

Is your check engine light on? If so, have computer scanned.

Sounds like a fuel problem, but always start with spark at plug. If no spark, check coils, wires/connectors, related sensors.

Next check fuel pressure from pump (static and operating). Then check filter, pressure regulator, injectors (firing and spray pattern) and related sensors.

finally, check compression (valve timing).

I've got a Ford Mustang GT 2007 that I disconnected the battery from. This was a horrible mistake, because now it won't start.

I've checked both the battery and tried a new battery with no luck, the engine doesn't crank at all. There is no sign of life and a slight "clicking" or "tapping" noise coming from under the dashboard almost at all times.

Radio, lights, heating, door chime.. Everything works. The lights doesn't dim when I try to start the car, but the car is completely silent, not a single sign of life from the engine.

It's an automatic.

I spent yesterday crawling under it and confirmed that the starter doesn't get any power.

The SecuriLock icon is slowly flashing on the instrument cluster.

I've got the feeling that it's something with the SecuriLock or some aftermarket alarm system that shut it down thinking it was a theft attempt - but I am not certain.

Is there anyone who's got any suggestions how to fix this?

It would be greatly appreciated.

The lights doesnt dim when I turn the key.

My apologies for possible spelling errors, english is not my first language.

Thanks a lot!

because you disconnected the battery you have to reset the anit theft unit otherwise it won't start. call a ford dealer or look online on how to doit.

Hi. My car has a hard time starting after sitting for any length of time over half an hour. I have had a new fuel pump, new fuel filter, and new spark plugs installed. I have also cleaned the MAS with the cleaner. The car runs perfectly fine after it is started, but it can take several minutes to actually start. It cranks, but does not start. It Idles at just under 1000 RPM. No knocks, no backfire, no rough idle. The fuel relay switch has been switched with the horn relay (both the same) and horn works with both, so I assume both are fine. I am at a loss on what to check next. Any help would be greatly appreciated. Thank you.

Check the fuel pressure if its within specs and also clean out the throttle body-could be coked-up

I tried cleaning the throttle body. didn't help. Also had battery and amps for starter checked and they are good. At a total loss.

Did you attempt to check the fuel pressure? I need the fuel pressure before we can continue

Also when it refuses to start look for spark-don't wait for nothing-let me know

Hi i have a 2007 Ford mustang and it was working perfectly fine yesterday then today it wont even turn or anything the power cuts on when i turn the key but thats it

**No crank at all/nothing/nada when key is engage to starting position

Could be the starter, starter relay, park and neutral switch/transmission position switch and ignition switch assuming the battery condition and connections are good. Note:If it doesn't apply disregard.

Recently installed 91 Octane tune with sct tuner car ran fine for a day was very pleased with the extra power. On the next day car started ran fine most of the day until I was driving home car started idleing funny and started bucking and backfire. Got wrench light on dash not check engine light. Parked over night started next day it had trouble holding steady idle tried driving it but wouldn't go more then 5mph kept stalling and kept bucking when it was driving. I returned car back to stock tune but the car won't start now. It's kicks over and immediately stalls.

try resetting security sytem first if no manual look online. then scan for codes to see if there is a problem . if this is a keep plugged in tuner to aldl then remove it as they will cause problems while plugged in and driven.

NOT THE SAME RIG---BUT THE SAME SITUATION

RETURN TO THIS POST AND LEMME KNOW WHAT YOUR BATTLE PLAN IS

scan for codes and check fuel pressure first
