motor swap help
i don't want to write a book to ill try to keep it short
i bought a 2003 c5 z06 and not even a month of owning it i dropped a valve and blew the motor
6 months later i bought a ls1 from a 1999 trans am with ls6 cam and heads
i swapped the oil pan replaced all the gaskets put arp head studs and ati crank pully.... i just put the motor in the car
when i started it the motor will start but shut right off .. i checked the codes and it was for cam position sensor a
i also broke the oil temp and pressure sensor while installing the motor so when i replaced the oil temp/pressure sensor and cam sensor i unbolted a ground next to the cam and oil pressure sensor and forgot to bolt it back down ...when i tried to start it again i had no spark and then i got 14 codes one of them being p0343
after realizing i forgot that ground i went back and bolted it back down .. car still starts and shuts off and the code p0343 won't go away i also tried another ecm so i know i didn't fry the computer.... i read the forums and people said if its not the sensor then maybe the cam bolts backed out ... i didn't get the crank pully off yet but i pulled back the timing chain cover enough to notice a lot of play in the chain ... does anybody have any idea what could of happened ?
i don't check the forums a lot so if you could txt me with any ideas i would really appreciate it thanks (203)859-0309
