What type of electrical current and # pulses per seconnd fire a L98 injector? I want to build a harness for an off car fuel injector testor that fires all injectors at same time at same rate.
any suggestions?

 

Bought mine at NAPA for 70 Bucks. Not really worth it as measuring the pressure drop is allmost impossible with the small graduations on most pressure gages. That makes it impossible to tell just what it is. Also, firing all at once is meaningless and will flood the engine. In the past, a few enterprising souls removed the rail from the manifold and then, with a graduated beaker underneath an injector, seen how much fuel each flowed. But once you know that, what do you do? Go buy another set of course - there's really no way to clean/rebuild them at home.
