Have you checked this yet?

Does this look right?

And no ken, I haven't checked that yet. I have been tied up the last few days.
I will be trying to check all of these things today as I am off work.

Unfortunately the battery is dead now and I gotta wait for someone to come by to jump it.

Thanks Guys!

the above diagram is how mine is wired.
I have looked everywhere for a diagram, including the haynes manual, and can't find one. If any of you guys no where I can find one that would be great.

The plug wiring looks okay, but normally the wires do not cross between the coils and the distributor cap..that is to say: trailing coil is normally towards the front of the car and leading is the rear. HOWEVER, this depends on how the rest of the system is wired. This is especially true since this is not the stock setup, so it could have been wired a number of ways.

Wiring diagrams and lots of other good stuff can be found here:

If you can tell me the wire colors at the ignitors and at the coils, I can tell you if it is right or not. The other option would be to post a couple pics clearly showing the wiring at the coils and at the ignitors.

Umm... on your diagram - the Trailing Coil is actually the one at the FRONT of the engine bay. The Lead Coil is the one more aft to that.

Somebody here correct me if I'm wrong, but I actually scratched 'T' and 'L' into the mount bracket to help me remember that.

Have a look at the FSM, or somebody here will know.

Heres some pics.
They are prolly not good enough but they are what they are.
I can try to get some better ones later if these aren't good enough.

Thanks again guys!

Looks like it might be okay. You rear coil looks to be setup as trailing. The YG wires (yellow w/ green stripe) are connecting to the trailing ignitor (one closest to alternator). The YG wire should also run to the tach. On the '80, the YG wire and tach wire were on leading, but it doesn't matter in your case.

The polarity on your trailing coil looks to be okay as well.

For leading (your front coil), I can't seem to make out the polarity markings. Check to see if your red wire is connected to the (+) end.

For the leading ignitor (the wires that you are holding in the pic), can you pull back the boot and let us know when wire color goes to which terminal. The plug will look like this:

Just tell us the top and bottom colors. The top is the trigger and should eventually connect to your leading coil (-) [forward coil in your case].

Few things: You have a wire (looks like black with yellow stripe) is not connected to anything. Maybe befor a coil (+). Also there is a yellow wire with a clip down there too. Looks like it might be a coil (-) wire.

Once the wiring is figured out, you might want to swap the coils around so that trailing is towards the front. It will be easier to keep track of the wiring that way. Would also help to get the coil harness of an '81-'85 car so that you won't have splices and changes in wiring color. I may have a spare harness for ya.

The red wire is connected to the + terminal on the coil. Along with another red wire the jumps over to the + terminal on the other coil. It goes to the l (vertical) part of the plug.


As far as the wires that weren't attached to anything....... Well, I guess they could have been left off when we changed the coil but I really don't think so. As you can probably see from some of the photos, There is a lot of stuff unplugged or missing from this car. However, It ran great before. Then it had the fuel problem and sat up for awhile now all of this. Other than the things I have mentioned nothing has been changed.

Thanks.

looks like a rats nest removal job, If you did not do the removal yourself, please reference the rats nest removal thread. Compare your rig to the tutorial, and fix the missing peices. This particular write up has a lot of pictures, https://www.rx7club.com/showthread.p...s+nest+removal , but their are a few of them in the 1st gen section, between reading a few different ones, about every gremlin is examined and eliminated!

Hate to jack this thread again but I can't see the point in making a new one for a similar problem..

If I wanted to test the coils, I'd hook up a test light with one side on the battery negative and then check each side connection on the coil.. correct? I get a working light when I hook it up to the hot(positive) side and no light when I hook it up to the negative. That means no power is going through the coil and its bad, right? If I'm wrong please correct me, and let me know how I can check! Thanks guys. (I also have a new rotor, cap, and wires)

I stuck a screw driver in each plug wire and got a spark this weekend.
So I guess that means all plugs are firing since they are brand new plugs.
So maybe its the timing or maybe its flooding out like someone has mentioned.
I don't have a timing light or a fuel pressure gauge so I don't know what my next move should be.


Thanks again guys!

txhellion

Also, I can't really see in my sight windows....... I'm gonna work on that.

This is the Tech section..not the classifieds. Let's keep it to technical trouble shooting, OK?

txhellion

Aye Aye Captain...........


How long does it take for my classified to show up.
I am kind of in a bind here and need to get this gone ASAP.

Can I check timing and fuel pressure without the tools I mentioned?

txhellion

I keep getting email messages saying that there has been a response but when I check there is nothing...........

You guys abandon me?

capitalcrew

I just got my problem fixed.. Kind of.

If you've got spark start checking everything else out. Pour a soda cap full of gas into your carb and see if it'll fire. Easiest next step..

My problem was I believe the previous owner that there was no spark and never checked for myself. Decided to check today.. and I have it. Car idles on gas in the carb but won't stay running. Somethings messed up in the carb.

Good luck man

txhellion

My car will start without pouring gas into the carb. I just have to lean on the gas pedal and it runs like crap and it smokes when I run it like that.

txhellion

I feel so abandoned.

In the distrubutor the diaphrams, you have to seperate the hoses and T them off into the 2nd nipple in the lowest part of the carb from left to right. and get actual plugs, not screws. if you need anything else ill try and help.
