2G 6bolt swap, no spark

[that_gst]

Recently did a 6bolt swap in my friends 99 gst. Its a 6bolt/2g head. The engine turns over but doesnt start. Its getting fuel , but has no spark.

We checked the ecu and replaced it and still no spark. We then replaced the coil with one of mine and still doesnt fire up. We pull one spark plus wire to see if there was any spark. There isnt any spark at all.

We've checked fuses , relays, harness to coil and cas etc . everything is fine.
It does not have a crank angle sensor since its a 6bolt oil pump. Has anyone beeen through this before ? We would really appreciate any thoughts or ideas on the the issue could be . Thanks .

What CAS are you using?

2G cas. I believe thats the issue, am i right ? I will wire it up and swap it out tomorrow if thats the issue . I have a black top one.

Yes you have to use a 1g CAS it has both cam and crank signals. The 2g CAS only has the cam signal.
