Car Cranks Won’t Start after (during) O2 repair
 

1) A couple days ago parked 99 Box to replace pre-cat O2 sensors (for snog, running fine)

2) With O2’s out I fired it up briefly to hear it loud

3) Car sputtered out after a few secs., not surprising with no O2 (I thought)

4) Installed new O2’s

5) Cranks but won’t start, smell plenty of fuel out the tail pipe, obviously no spark at all

6) No obvious flame damage to anything above O2 sensor ports (flame damage)

It basically quit not to be started again when I ran it briefly ran with nothing in the O2 holes…coincidence? Ideas any one?

go back over your work...you knocked something off

Maybe the computer got confused, unplug battery and let it reset?
Just a thought.

That was my thought but:

- Nothing around O2's (where I knocked around busting my knuckles to loosen them)

- I' d had OBS II on and attached all week end (disconnected now)
- Battery went dead Put it on charger (but started and ran briefly after recharge

Looked allover for something loose. I'll try disconnecting battery...nothing to loose,

Thanks PK
