Okay so my stang won't stay on thought It would of been the alt. so I swapped it out last night car cranks on just 2 min later it fights to stay on an just dies and if I put it into gear it quickly dies an jerks it's an auto by the way not sure what else it could be

Can you read any CEL codes?

 

[rangerbert]

Maybe fuel filter needs changed.

No CEL codes given I changed the fuel filter along with plugs last summer and use nothing but Chevron gas so idk if it might be something else

Charge the battery and see what's up

I changed my alternator after similar issues and found it to be the battery after the fact. The battery just sucked even though it tested 'good' according to the load tester.

 

[Terminator]

Charge the battery and see what's up

Took battery out had it checked was at 30% now it's fully charged will plug her back in tonight hopefully that was the issue

Hope that was the problem bro

So it wasn't the battery it turns on just fine but than 4 secs later turns off I feel like it could be a sensor

IT's strange that you don't get any CEL light or codes. Maybe the battery has a bad cell. Can you start it and have someone pull the battery cable immediately?

Have you recently done a tune up in which the spark plugs weren't calibrated?

Well didn't know the Spark plugs needed calibration

 

[05MUSTANG4.0L]

Yupp this is for a 05 v6, I didn't know either

Yea before I didn't know the v6 had spark plug wires where as the v8 has coil packs

 

[05MUSTANG4.0L]

Me neither I don't know anyone around me with a gt so i've never seen one up close

 

[maldog]

It sounds like the fuel pump to me? Have you had the fuel pressure checked coming into the fuel rail?

 

[primer2tone]

Ill try that but I had the battery tested they said its fine

You need to test the charging system as a whole. You might not be getting a charge back to the battery. Or maybe a crank shaft position sensor. Just a guess.

I was thinking the same thing I just had it towed again to my shop the mechanics there are gonna look at it
