GrayZee Posted March 29, 2005 Share Posted March 29, 2005 Simply just running out and buying new parts isn't the answer. First of all how do you know that "the injectors aren't firing" Did you test them? They could be firing with no fuel pressure, or there may be no electical signal from the ecu to the injectors, or... the injectors could be toast. Here are some things you should look at: 1. fuel pressure test 2. injector/ecu electrical test (using a injector test light) 3. if it passes the first two tests, supspect the injectors themselves. (not all that likely, especially if the engine ran recently) Quote Link to comment Share on other sites More sharing options...
