backfire then no power

the car absolutely will not turn on, no dash, no capacitor no nothing, all fuses in dash panal and engine bay boxes are still good, is there a fusable link between the dash and harness, or any other fuses that aren't in the two listed places, i've been told to check the starter but i'm not sure if that will yeild any results. the battery is very strong, it tests at 14 volts. it did this after a backfire

Did you check for voltage in the PDC/interior fuse box?
The backfire may be a result of losing voltage to the PCM via a bad connection, then breifly gaining it back, and losing it again. The fusible link at the starter will not keep the fuse box/PDC from getting voltage. It will let the battery not be charged, but the voltage is good, so that's not the issue. Check each fuse for voltage at the little spot on the top of each one, both sides. A test light works great for this. There may be a feed wire that has failed underneath.

backfire may have hurt a sensor, esp the map. You need to check them. other than that i dunno, had to blow up some electrical component.

I'll keep these things in mind when I get a chance to look at it this weekend

but yea soon is I solve this mistery those cams are coming out and going up for sale, not worth the head ache, but i'm still going to be getting at least some of the power back, through other means of course. what might that be you ask? just have to wait and see

Does your car have an ASD (auto shutdown) relay? If it does, it might have gone bad. It would be in the engine-bay fusebox.

how can I test that?

Hopefully you have another relay of the same type being used for something else, like the horn relay or A/C compressor clutch relay. If they're the same, just swap them and see if you get power.

i think I do have a spare, I still have the AC relay but I have no AC

Or just pull out the fuse and check it for voltage.

ASD relay is the same.

Nutmeg,
The fuse would only tell him that the relay is getting power, (still important) but won't tell him if it is switching the power on.

i've narrowed it down to the terminal as we put jumper cables on it and it started right up, thanks for the input though guys

Good to hear. Now get yourself some real cams
