Question : No SES.. or injector power at Inj...

[Fierobuffoon]

Simple question, or is it?, Car runs when fuel is added to intake area.., But No NOID light on inj,Tach works, Most probable bad ECM? all fuses check out, power is where it should be. 93 GP Auto,

did not have Chip in Key, soo can the anti theft system keep the Ecm from working, or Vote for just blown?

If i had an entire OBD-2 harness id use the Ecm from that, really Dont want to Convert it to Obd 1.5.. but should i?

Expand on what you got... Is it all stock 93 parts?

And don't you dare convert it to OBD1.5!

IF it was passkey related, the vehicle would still have the SES light on. With all fuses confirmed good I think I'd be taking a closer look at the ignition switch.

IIRC, the 93 GPs didn't use PASSKEY yet...

[86FieroSEv6]

Hmmmmmm, odd. I was pretty sure this nightmare started in '92. In either case, I'm pretty sure his problem isn't with any kind of factory VATS as he stated his SES light isn't coming on.

nope, W's didn't get the PASSKEY system until 1994, when a bunch of changes went on, and incidentally a SECURITY light was added to the dash.
