Either your security system or no rpm signal. Engine cranking, do you have spark at the plugs? The rpm signal comes from crank sensor, but, don't replace anything unless your testing points in that direction. Just my opinion.

Yes I'm getting fire if I spray starter fluid directly into intake the vehicle starts until starter fluid runs out. Is it possible for one bad injector to keep the other 7 from injecting fuel? I'm almost positive it's not the security, and if you might ask no my key does not have a chip just a regular key with a separate factory security remote.
