Not leaking any fuel (no fuel smells) and the injector is seated properly.

Being that you have to take the whole intake manifold off to get to the #2 injector I'm not sure how I'd check to see if it had voltage without putting everything back together and leaving the plug in a place where I could actually get to it.

 

maybe pull the schematic for it and see if you can tap into it at the computer?

 

new symptom I now only have two cylinders the 1st and the 2nd aren't firing

 

so no fire with the spark plug grounded on the valve cover?

 

Follow the FI harness from the injectors all the way back to the computer. Sounds like the harness may be chaffed/pinched.

 

Put some either or gas in the intake tube and see if that makes it run on all four. That well tell you for certain if it is getting gas.

 

injectors 1 & 3 fire together and 2 & 4 fire together. If 4 is firing, its probably the connector or from where #2 splits from #4.
