Hi eeryone i put a j-spec engine in my 87 tII and i have a problem the injectors wll not open when i crank the car with the top part of the intake manifold taken off. I have started my buddies car with my computer, and my afm, i know the injectors are good caue they open when given a + and a - charge. i have been messing around with this for ever and i am getting pissed.somone i talked to said to check the month of my car cause in the middl of the year in 87 they switched fromlow to high ohm injectors and the computer wont run the opposite and i don't knwo how to see what month my car is so there it is. any help would be great thanx alot Ryan

 

The cars that require a low impedence injector, are those that have a solenoid resistor. Whats a solenoid resistor, I just heard you say. It is about six inches long, an inch and a half wide. Its aluminium in color. Its attached to the fender, just below your afm/air filter. Has one large plug on it. YOU usually can spy it by looking under the afm/air filter from the front of the car. Shiney aluminium.

If your car has no solenoid resistor, then you have to have the 12ohm injectors.

I think the TED site has some info on the year. If I see it I'll post back. But a sure sign of the need for low impedence injectors is the aluminium covered solenoid resistor.

Another fairly sure way to tell is look at the electrical jack on the injectors. Stare at it and you'll notice a *tab* on the injectors jack. If the tab is centered on the injector, then its low impedence. If its offset from center, its high impedence. The connector that goes on the injector should have a notch for the tab on the injector. They should match the injecotor.

I'd check the solenoid resistor or the lack of .

 

hey, thanks a lot that is exactly what i needed to here about the high low injectors,only one thig iknow what the selinoid resister i so thats good i am just letting you know. Now my question is if i bypass the resistor and get 12 volts t the injectors will the comp send the ground signal or what? do i have to get the low ohm injectors or what? thanx again for all your help.

hey cool another wisconsinite with a 7, and hes got a jspec, sexxy!
BTW if u do have to get the other injectors let me know, id be interested in buying an extra set to have them blueprinted/cleand by RC
