Thanks for this wonderful site, very good reads. and alot of them!

I have no injector pulse on my 95 riviera 3.8 sc, The injector fuse is good and has power. I do have 12v at injectors when key is on. And injectors all read 14.2 ohms across injector terminals. Noid lights do nothing when cranking. Car has 35psi fuel pressure at the rail. Good spark (5.69 -5.73 ohms across each coil pack) and good compression also.
Any help troubleshooting this problem would be appreciated.

Take a look at the wiring diagrams at autozone.com, repair guides to trace the source of the problem.

I have the same problem, no injector pulse on my 95 riviera 3.8 sc, The injector fuse is good and has power. I do have 12v at injectors when key is on. And injectors all read 14.2 ohms across injector terminals. Noid lights do nothing when cranking. Car has 40psi fuel pressure at the rail. Good spark (5.69 -5.73 ohms across each coil pack) and good compression also.
The one and only reply was of no help to me. Does anyone have any specific things I might check?

Thanks

What is the security light doing when you attempt to start, blinking or on steady?

When I get in car the security light is flashing, When I turn key to on I get a steady light, then about 5 sec. afterward the light goes out. I have read posts about how to bypass the VATS system and I have made a splice that has the matching resistance of my key. However I can not find the two wire I need to cut and add the resistor wire to. Does anyone have the exact color and location for the wires on a 95? Also if I could find the theft deterrent module I may be able to trace from that. Just tuff to find anything under the dash when you are upside down with very limited hand movement. Any photos would also help.

Thanks for any help

That is how it should work, so evidently security is not the problem. This could be the PCM!

Thanks and I know how it should work. :screwy: I think when I go to start position maybe I lose contact on the security wires and that is why I need the infomation on which wire to splice--Like to remove all doubt!
