Default Running on 4 or 5...

Got to the point of firing the old gal up at last!
Little history...
Motor was used when picked up late last year.
It has taken me this long, due to work etc, to be ready to fire it up in the new home (Range Rover).
Rebuilt the motor while it was apart etc.
Seems to be running on 4 or 5 cylinders.
The leads are getting a spark to the plugs, checked with timing light.
Exhaust manifold temps are all over though. Passenger side between 150 and 160. Drivers side is @140 at the front, down to 90 at the rear.
Sound like bad injectors to anyone? Not checked with noide lights, but will in a little while.
Thoughts on these injectors, that have been sat @7 months, while I had the engine and no telling how long before that.

EDIT: 2 rear cylinders on drivers side are getting a pulse, 2 easiest to check and the coldest cylinder with the IR gun.

A good suggestion on the injs.... See that frequently with the J/Y engines I deal with.

Thank you!
With there being a pulse on the plug, and fire on the wire, it just about only leaves the injectors on those cylinders IMHO.
Just wanted a 2nd opinion...
Now, the big question....best and most reasonably place to get a full set?

Dont ask me, but it is now running on all 8!
All manifolds are roughly the same temperature now, and even drove it!
Will ask the wife to upload the video of my 10yr old breaking the camshaft in, with nothing but manifolds for an exhaust.

Injectors were probably stuck. I came here to suggest forcing them open with a direct battery connection.

I drove around for 2 weeks on open manifolds. Sounds great like that.

Only problem is, what gets melted in the mean time!
My exhaust guy said @$300 to go from the Hooker manifolds, to the rear silencer that is still on there. That includes 1 cat, o2 sensor bungs, etc Not bad IMHO.
Now I have a tranny leak, from inside the bellhousing...God I hope the seal just got dry and it will seal up (yeah, I know..). The tranny was rebuilt and has been sat since December last year.
