...heard some time ago about possible injector polarity problems for certain rare injectors, but I've never come across it personally. Have you tried reversing the connections?

no, i put them in what i thought was the "correct" way based on how the old ones were plugged in and also the notch on the plug. i was afraid to reverse them in case i screwed up the injectors. can anyone familiar with the siemens injectors address this? thanks.

Shaheed, the Siemens plug in the same way the stock ones do.

back on the crack pipe.....danno sent me some delphi injectors to replace the siemens and the car started right up with these, BUT......it wouldn't idle.
on a hunch i jumped the ISV as described on lindsey's website and now it idles, but just barely at like 200rpm. fuel pressure looks good, but you cannot rev it, it dies right away when you try to.

so i take it this means either my ISV has gone south or i connected some vacum hose incorrectly? *sigh* here goes the intake manifold again. i hate this POS
