Are the injectors opening? Do you have spark at the plugs?
We have spark, but aren't sure if the injectors are opening.
You can get a tool called a "noid light" to check the ground signal to the injector, you can use a voltmeter or regular test light to check for 12 volts at the injector. Try a search and you should be able to find the tool for your vehicle.
