Timing issue
If it's not real a crank relearn may take care of it.
However if the previous CKP was bad it might have knocked out a plug or two. I would probably slap a new set of plugs in first.

Rained all day today but found a few minutes to do a compression test on 1 and 2 cylinders. Compression was cyl. 1 165psi cyl. 2 160psi cold plug one looked like it just came out the box and 2 looked like it was gas fouled black and sooty. It has injector pulse and spark. Checking the the mail order tuner to see if theres so.ething off with it. Any idea. I did also check wire colors on Injector harness looks ok will ohm out tom. If nice out.

One way to verify timing is to put the cylinders you are concerned with at tdc on compression stroke and mark the balancer then use a timing light to see if the spark is hitting on your mark or anywhere close to it. Mark 1 cyl at a time or put the number of the cyl on the balancer as your mark so you know which cyl your looking at when the timing light flashes.
Be hard to tell if it's hitting exactly on time but will for sure tell you if it's way off which would indicate cylinders are swapped somehow.
Had that happen when someone installed the crank tone wheel wrong on a VW. I had fuel, spark, and compression but would not fire, it was firing 90 degrees off time. The tone wheel (reluctor) on that car was the flywheel itself, somehow a genius figured out how to install it wrong when the bolt pattern on it is offset drilled to make it "impossible" to put on wrong lol. They ran the bolts in crooked to make it fit on wrong..

did you ever verify that the 2 harness connections for the coil pack banks were plugged in on the correct sides?
this sounds very much like you have an issue with some crossed connections. if those cylinders have compression, spark, and fuel, and aren't firing, then they aren't getting spark and fuel at the right time.

It does. I had that exact thing happen when a friend helped me with his car one time and he pulled the coil harnesses off the coil packs and off of the brackets and then wired them to the coils all out of order. Had 4 dead cylinders after that.

Ok so tested #1 & #2 cyl. Today 1 is one of the dead cylinders. 2 is a good cylinder well running one anyway. Ohm out inj. And coil on those two cylinders. Both injectors are on the right pin. And coils are o. The right pin. Gonna have to dig deeper my wiring is correct. I'm gonna try to flood it. Disconnect the coils and crank it. Pull a plug and see how wet it is. Maybe run it off carb cleaner and see if it smooths out.

Trying to read how wet plugs are wont tell you if you're firing the cylinder at the right time

Ok so I swapped my home made harness out for a 2002 camaro harness. Now it wont start at all wont even fire off ether pulled #1 plug wire and it has spark. Wtf is going on with this car. Before the harness swap it ran off of 4 cylinders now not at all. Please read thread before telling me to do thing already have been done. Please help.
