I have fuel under pressure to the fuel log but the injectors arent opening.  I have put a test light to the wiring going into the injectors and there is juice going to the hot side when I turn on the key, I'm using a test light,  but the current doesn't seem to be pulsing.  The light stays on until I turn off the key.  If I squirt some fuel into the intake, it will run until the fuel runs out.  I'm out in the middle of nowhere, Mexico so What ever tests I do will have to be without any scanner or complicated test equipment.  I was doing fine and then one day in town it just quit and that's it.  The battery is fully charged, it cranks fine and has a recent tune up.  Thanks
