Low imp question
I'm building a fuel injector cleaner from a fuel rail with regulator a pump and some old beatup but useable injector clips.
Thats the easy part. what I need to know is what size resisters I need to buy to fire the low imp injectors. maybe a diagram would help. thanks for any help. I've read a few differant things. I need them to fire at 6 ohms right? |
First off what color are the injectors? Wow, so interestingly annoying. Search here to see which injectors you are running in the first place, whether hi or low.

there low, thats why I'm asking the question. I've been around long enough to know what injectors are what. But I'm running stock 550 (early 87) primarys and gslse 720's as secoundarys.

It’s the computer that needs the impedance to be right not the injector. In the ECU/computer are injector drivers that needs a certain resistance or they will burn up. The fuel injector could care less.
For your purpose just supply 12v and the cleaning fluid. I have doing this for years with no problems. |

I need them to fire at 6 ohms right? I've done this in the past. Made a harness with a injector plug with a six ohm resistor in the wiring going to the batt positive post and then put the other wire to the batt neg post. Injector opens when you touch the wire to the neg batt terminal and fuel should flow thru the injector on whatever kind of rig you made for fuel flow. Personally I just use a old secondary fuel rail and zip tied two inectors on that rail with fuel coming in the rail and the other end blocked off. Injector being tested pointd in a measured container (mearsuring container?). I've done this in the past without the resistor and held it open for up to a minute.........not a recommendation. I later added the resistor off a old stk resistor package. On another of my goober headed rigs I just got a long piece of fuel injector hose and tee'd it into the fuel pressure line just after the fuel filter (now have FPR pressure). The other end of the hose clamped to the inlet of the fuel injector. Same elect rig as mentioned earlier and the fuel injector pointed into a measuring cup. You could actually run the engine at idle doing this to keep the batt power up. Nice fire extinguisher I have. How 'bout you. |
thanks hailers2, thats the info I was looking for.
My plan is basiclaly the same secondary fuel rail, over a bucket. |
