05 Mustang Gt Mods- include Jlt series 3 cai, frpp intake manifold, jba lt headers, brenspeed Detroit rockers n/a cams, port and polished heads, comp beehive springs, jba 3" H pipe, flowmaster axle backs, dyno tuned. other mods but not engine or fuel related.

Problem car stalled then will not start. when it stalled was about to turn so clutched to down shift and rpms dropped. tried cranking it and motor just turns over. occasionally will fire.. also backfires every now and then.
only codes are 2104 and 2112 both throttle body related. have replaced both tb motor and tps. aslo have changed fuel pressure sensor. will data log tomorrow. also have battery is low. Checked 1 spark plug didn't continued cause I believed it was throttle body. also cleaned mass air flow sensor.

Hmmm. Sounds like when one one of my cam phasers failed...

Check the Altenator out put?

 

[Crabro88]

Can u check alternator output through data logging or with multi meter

 

[stkjock]

IIRC, there is a PID for voltage out put

 

[Crabro88]

As far as cam phaser did cam gear break or did it just spin freely

Also can u seen cam phaser and timing chain through oil filler?

 

[RLF9409]

The spring broke and somehow broke the alignment pin on the cam.

I always get so confused when reading peoples titles and threads. If the car turns over then it is cranking. If it wont crank that means the motor will not spin at all. I would check what others have pointed out already. Plus I would look for vacum leaks hoses any unmetered air getting in. Ive seen cold air intakes pop off and cause the same problem

Well found a broken rocker... Any way to test or check how far the damage goes.

How about some pics? Hopefully that's all that got damaged.
