A few months ago my car was stolen and stripped. I got it back but whoever stole it cut the wires from my safc and blew a ****load of sensors. One of the sensors is the ignition signal primary( code 21). What the hell is that??... If anyone one knows I would really appreciate a heads up. I want to finally get my coupe back together. Its been so long and I NEED to drive it again!!! Please help!

In regards to me searching, I did. Searched code 21 and search various sequences of ignition signal primary, ignition signal, primary ignition, so on... Im not a noob, nothing came up. Thanks for the reply though, I realy do appreciate it. Hopefully I'll get it figured out pretty soon. I have a friend with an extra dist. so I'll try that out. Thanks again!

<dood thinks not zerothread?id=262051 if the harness and wiring is good then check out the power transistor(cheaper of the two possible), then try the dizzy. I bought a dizzy thinking how could my p/t go out and thats what it was 5 bux from the junk yard is way better than 300ish for a dizzy...

I felt like a jackass for the whole search thing, went to search again to see if i somehow missed something yesterday... I would have found alot more if I had clicked on "archived" instead of just looking through rercent content. So I got schooled. Sorry. Anyway, My computer says i need a tps, knock sensor, cam angle sensor, (I think) power transister, and a new maf, so the hunt will be on this weekend. Picknpull here I come. Also have a friend with an extra single cam in the garage, I'll see if any sensors from it are interchangable, but not holding my breath. Thanks a ton for the help.

nothing personal at all, we just get a few too many people claiming to have searched when they clearly have not..... always check the archives too, as well as the how to section, I have a couple of write ups in there.... did you reset the codes to clear them? then try starting and check /clear again maybe you will not need all those pieces. but if power was still going to everything and they cut pos/neg at the same time your screwed.lol sorry about your car but doesnt the 240 seem like the civic 5 years ago?....
