If the plugs are dry that sounds like the injectors arent firing.

The 2.9 is batch fire. Meaning it fires 3 at a time. The ECM grounds the injectors to fire them. If the injectors are getting 12v power, either the wires from the ECM to injectors are bad...or the ECM is bad. Since its all 6 id bet on the ECM

I’ve heard they go out all the time on these, is it really just plug in play or will need to program it. Any way to diagnose it’s the problem?
Thanks

I dont know how to test it. But yes they are plug and play....just get an 88 ECM. Only difference is manual or auto trans.

I manual swapped, stick with original auto or get the manual? I’m thinking just stay with it.

Manual. I went through that with my 4.0 swap, I had a manual and the only computer I could lay my hands on was an auto, so I ran with it for years. Finally decided to buy a manual computer and found two things… my auto computer was always a little funny and it also had bad capacitors at the end. The manual computer fixed a lot of things and made it run a lot better.
