you got a multimeter? you can test the resistance of the injectors, dont know wether these are high or low impedance but sure the net would yield the results but they both should be the same so theres a start...
last year i had a misfire on an rx8 engine that led me on a merry dance i tested my own injectors and cleaned then myself....
1. i wired up the injector to a 12 v power supply and using a syring and bit of airline i forced the syring plunger in and enabled me a clean the injector with cataclean and also 2. verify spray pattern and 3 verify actually open when 12 v on.
bit heath robinson but proved injectors where not at fault.

Ok, finally sorted it.

Firstly, sorted the leak out on the secondary rail by installing in the original rubber o rings into the intake manifold.
Lastly, found out the standard primary injectors were stuck closed (some that I purchased to take out my ID ones)....changed them over for a spare set and fired right up.

Cheers for the help guys.
