Here's the story: The car sat for a good 1 1/2 with gas in the tank, we siphon'd out as much as we could (which wasn't all of it) so there's some pretty gnarly gas in the fuel system.

Right now the car's running off of #1 and #4, #2 & #3 have air and spark (check that already), but I don't know how to test for fuel...I use a multimode meter right? lol

measure voltage between the two wires at the injector and compare to the working injectors. the computer pulses ground to the injector when it wants fuel.

injectors should be 11 ohms.
