I have a 98 camaro that I have swapped a 4.8 truck motor in and still running ls1 5.7 wiring harness and intake and injectors and all of that... Its getting spark and its getting fuel and still wont start. Can somebody help me please

 

The 4.8 could be a gen 4 with the different crank sensor. If so you'll need a converter box to get it running. That's my first guess based on the info you gave
