06 gt mustang. She ran perfect after motha thumpa install w new phaser timing chains. Let it sit running. Shut off and started again no problem. Well little while later we went for test drive. Didn’t make it out the subdivision went to give it gas she fell on her face. Now she cranks but dies shortly after. I got gas, spark, battery, compression is good. She will not run. Switched out new fuel pump,oil pump ,water pump. And new vvt sensors. Now some people say get a tune but old school guys say I don’t need a tune for it to run. Sooo idk u. Any ideas

 

Did You Have a Check Engine Light After Cam Install?
Any Trouble Codes?
Have You Tried a 20 Minute Battery Disconnect To Reset PCM?
Is Vehicle Stock Except For Cams?
Have You Checked Actual Fuel Pressure?

Check the documentation on the cams -- pretty sure they do require a tune modification to run right
