i did a 5.3 swap on my chevy silverado 96
the first time i tried to turn it on
it fired up
but now i have a problem “IT WON’T START”
-it has spark
-it has fuel
-it has pulsations on the injectors
i change the camshaft 212”218”
new sprigs
new pushrods
any ideas??

 

You changed the camshaft and then it wouldn't start afterwards? I would start there and check valve timing.

 

thats what i am going to do netx monday

but here its an other thing
if i remove the fuel rail with the injectors
its fired up with some start fluid
