actually i have just ohmed one injector ( the one whose harness connecter not covered by the ) it is about 12 ohms . . . this is the injector that i NOIDed . . dim light . . maybe a flicker . . the lights intensity varies as throttle is modulated . . . ( the only way to make the car run longer than 8 secs is using starting fluid) . . .Do you want me to ohm all the injectors . . ? ? it would require me to remove the pleum thingie . . .

Answer

the most reliable way is to pull the intake plenum.
sometimes you can get to 1 by the oil fill cap and another on back corner by alternator.
if 1 injector shorted bad enough computer will shut down driver .
12 ohms is around normal. 12-13.
normaly if one is less than 5 car start and die or wont start.

Answer

All of the injectors should ohm about the same. have a high failure rate if 1 is bad i would replace all.

injector 2, 4 and 6 are 9.5 , 12.1 and 12.5 respectively

And answering your question from post# 2 . . evrything got replaced after a no start condition . . . actually the car had issues with starting when hot . . . it would only start when it got cold . . . idle was rough and the only way to drive away hot . . .was to use starting fluid . . ( huge quantities of it) to initially make the engine run for 10-15 secs . . .. after this the car would run fine . . .

#2 is bad and#5 is bad
I would replace all
