Are the injectors being told to fire? In other words, did you check for power and ground pulse to the injectors?

Got power to all injectors one is shorted will one bad injector still cause it not start?

When cranking don't hear any of the ticking ? Fuel was 2 years old and tank all clean with new fuel

Yes it will cause a no start. The shorted injector will not allow the ECM to pulse the injectors. Unplug the shorted injector and see what happens. You should probably get new injectors as the originals are probably all dirty anyway. Check the classifieds here at TGO or get a set of refurbished injectors from SouthBay, I read nothing but great praise of SouthBay from members who have dealt with them. GL!

Probably got bad injectors. Same thing happened to me. Fuel sat for awhile. Replaced everything fuel related except for the injectors and couldn't get it to start. They ohmed out properly as well. But were clogged up. They were the stock multecs. Put in some Bosch 3s and fired right up.
