thanks Chris,

i did not dig that far as i realised that i was running on 3 cylinders; so i stepped back and put my diagnose hat on instead of throwing more parts & money at it:

1. i tested each wire down to the spark plug for spark, i found an intermittent spark on #2, so i replaced wire, i start and still running on 3 cyls
inders
2. pulling distro lead off, i crank a few times to prime cylinders, i pull plugs, 1, 3, 4 anre wet, 2 is dry

3. i pull injectors and rail and crank, gas shoots from 1 3 & 3, not 2

4. check & clean electrical connection to #2, still nothing

5. pull out #2 injector & bench test, it does not click, i test my hooptey 3v tester on VP garbage injector, it clicks

6. connect vp injector to rail and crank, i have gas now - CPU & electerical connector & trigger points are good!

so i was tempted to put back together like this, 1 vp and 3 orig injectors, BUT then i remebers that the VP inj only work at 18 lbs, i m currently set at 31 lbs so this will result in gas dumping into the crank case - this issue i had before

results - I need rebuilt inj - if anyone has any leads i woud appreciate it,

thanks R!
