Injectors not firing
 

In addition to other tread. All injectors are new.

Cylinders 1-2 not firing
 

Had the car running fine. After a winter shake down of about 15 miles car started bucking. Now cylinder 1 & 2 don't work. Plenty of compression and grounds seemed ok. Replaced plugs,checked,cleaned points, checked relay on board , (seemed Ok with a swap). I believe trigger points are for cylinder 1 and 4, so I ruled that out. Any input????
Thanks.

Re-check the grounds.

Rechecked grounds and I did find a loose wire that came off the crimping. Used alligator clips for a quick connection and seemed to work.
Thanks David.

Okay, I crimped a loose wire on the f.i. ground under the phlenum, cracked some of the brittle jacket, but seemed to be ok. still have nada on cyl.1-2. What else can I check?

I found out that the injectors on cyl.1-2 were clogged. After a good cleaning on the bench all worked out well. Thanks for your help again.
Now to cruise on Memorial day weekend.
And the obsession continues!
