LS engine swap info

I've cleaned the rails a couple of times...we were wondering the same thing....after tryin to start it, there is fuel on both rails and pressure at the shrader valve turns over, runs with starter fluid, but not on its own...no throttle hooked up but shouldnt need that yet anyway

Do you mean the throttle body or cable? The MAF MUST be connected and piping ran from it to the TB. Just having it plugged in and hanging there won't cut it if that's how I'm understanding you have it. And id try pluggin in the O2's as well. Did you have your computer's VATS tuned out? That will hinder the injectors from operating.

also, you can test your injectors using an OHMS meter (multimeter). just unplug them and touch the prods to the 2 in the injector. i think the LS1's are 14-16ohms.
