another horror, no start, no fuel no spark
after 20 min of idling it will shut off. Ran scanner, no codes. Used noids on injectors. No light. No spark. Swapped in fuel pump. New icm and new coil. It did blow two fuses, open for ignition and one for one set of F.Injectors. I don't know if the fuses went when i swapped the injector rail and reg. Also new spark plugs they were fuel soaked black soot. New O2's both sides
so re-cap what i found
1. no spark
2.no fuel at injectors
3.no codes present or history
4.used noids on injector harness, nothing.
5. Two fuses perhaps related or unrelated one for ingnition and one for half the injectors
6.new fuel pump, filters and reg.
7. one side of the O2 was at 444, other side was at 4
I'm fine with doing the work, I'm fine with buying a part. I just don't know what direction to go anymore

If its blowing fuses, you have to look for shorts in the wiring, or some cause. Have you checked the other fuses like the ones that support the PCM (PCM IGN, PCM BAT)?
Your "444" mV O2 sensor reading is correct for a cold sensor. The "4" mV on the other side would probably indicate the sensing element purple wire is shorted to ground, or there is an internal short in the sensor. Soot-covered plugs would result from the low O2 sensor reading, but that would only affect one side.
Odd that the injector fuse blowing did not set DTC 18 in the PCM, since the PCM diagnostic is basically to check the voltage on the injector circuits.
Sounds like major wiring problems.

damn
checked all fuses. Only found the two. Went thru harness best I could. Nothing touching chewed or burnt. This car keeps it up, the whole thing is libal to burn to the ground and collect the fricking insurance. I hate wiring problems

This sounds similar to a problem I'm having right now. One 02 reads 003, the other won't go above 100 (although it did the day before). It's stumbling, misfiring and running poorly. I got fed up and it's at a shop, I'll let you know what they find.

something i never thought of
I've owned this car for three years coming up
since I've bought it. The security light has always been on. I only have one key. No chance the security is kicking in after running is there?
