Want this question answered?
Hi, I want to fit new injectors to my eldorado 1976 and have now found some from a company who believe it or not have 50 of these at $35.00 each..anyway in answer to your question if you have the old ones (which should be green and not blue) get your ohm meter and measure across the two terminals this way it will give you the ohms...the full presure if you are interested should be between 36 and 39 psi...ThanksChas
The difference in between Ohms and Ohms CT is that in Ohms CT it has CT at the end.
ohms law.
In series like so ---6 ohms ---- 12 ohms --- , the total resistance is just 6 ohms + 12 ohms.assuming you mean in parallel like this:_|---6 ohms-----|-|~|-_|---12 ohms---|then the resistance of this can be calculated like so:1/6 ohms + 1/12 ohms = 1/R (where R is the resistance of the circuit as a whole)2/12 ohms + 1/12 ohms = 1/R3/12 ohms = 1/R1/4 ohms = 1/Rso R = 4 ohmsA few notes, if the resistors are in parallel the total resistance will always be less than or equal to the lowest resistance in parallel (i.e 6 ohms in parallel with 12 ohms will have resistance less than 6 ohms).Also if two resistances in parallel are the same, then the resistance is half of the resistance of both resistors (i.e. 1/2 ohms + 1/2 ohms = 1/R; 1 = 1/R, R=1 ohm which is half of 2 ohms).This process can be extended to 2 or more resistors in parallel.i.e if we had a 6 ohm, 6 ohm and 12 ohm resistor in parallel we could go1/6 ohms + 1/6 ohms + 1/12 ohms = 1/R(1/6 ohms + 1/6 ohms) + 1/12 ohms = 1/R1/3 ohms + 1/12 ohms = 1/R4/12ohms + 1/12 ohms = 1/R5/12 ohms = 1/Rso R = 12/5 ohms or 2.4 ohms
yes.
2.9 ohms is nominal. To check the resistance remove the IDM module and probe the connector with an ohm meter. Do not pierce the wires. The injectors are activated with around 100 volt pulses. Cut or pierced wires will leak current and cause injector drop out, or IDM failure.
Found the answers myself: TJ19 (green) and TJ20 (blue): low impedance, 2.0 to 2.7 ohms TJ23 (white): low impedance, 1.0 to 2.0 ohms
U really dont need to know the volts to your injectors just the resistance they put out use a multimeter to test the ohms of the injectors to make shure they are functioning proplerly
135 ohms new, and will function properly down to 114 ohms. The chart in the '86-'87 book shows: Empty=110 ohms +/- 7 ohms Full=3 ohms +/- 2 ohms 1/2 full= 32.5 ohms +/- 4 ohms
That's an excelent question. I have asked on a forum the similar question, and the replys i received were one of two 1) there are two types of injectors one is high reading ohms and the other is low reading ohms. as long as you stay within either the high or low range (high 14.8 to 12.0) then everything will be just fine, and therefore you can use it. 2)if the ohms are not a match (14.6 plus or minus 0.4 ohms) then you can not use them and it will fry your computer. So which is correct? I'll have to watch to see what other people say.

yes!! throw in trash go to local gm dealer and order new injectors
CSV or Parts Incorporated
Just take new ones:)

3000 ohms are 3 kiloohms.
Ohms are smaller than k-ohms, so number of ohms must be a bigger number. Multiply k-ohms by 1,000 to get the same resistance in ohms.
