VA Electical gurus please help

I have a 87 rx7 TII. Get your laughs out cause it has not blown up yet and will not.

The problem is a series of thing.
1. I many times turn the key to start and all I here is a click which I though was the starter going bad.

2. Then after cranking it a few times it would start turning over but there is no spark and or fuel that I know of.

3. But eventually it will start which rules out something but I am not sure what.....Eventually does not work for me because I am a delivery driver and I need it to work instantly.

4. When I am on the highway and I put the car in 5th gear the car dies. All power is gone. I tested this out when I was sitting at idle with the clutch in and the car dropped idle and barely stayed on. It sometimes dies even when in idle and shifted in to 5th gear

I am not sure where to start. I need to learn more about electrical to be honest.

The guys at advanced auto just told me that it could not be my battery because the one I am using now has more CCA than the factory recommendation. =(

Dies EVERY time you put the shifter in fifth gear? Serious miswiring by someone. Like a radio installation or any other aftermarket gauge/stuff.

To many CCA? First time I've heard that one. Sorry, I'm not a true believer in that one. I can be convinced if I hear a good argument on why that would be the case. Spinning the engine over too fast? They've got to have a reason for saying that. Are they trying to say it's a hung starter because it's turning too fast. Don't bother asking them. I was just wondering.

No he was staying that CCA were more than enough to start my car so the battery would not be the problem.

I missed that *not* word. Sorry 'bout that.

A lot of things can cause the *click* but no start. It can be a bad starter solenoid, a bad ignition switch not carrying enough current to pull the solenoid in, a bad set of brushes in the starter.

If you've got the dough you could try another starter.

Or, if you've a slight amount of talent, you could try this:

LIft the TRAIL COIL ASSY up and out of the way. Only three nuts hold it in place. You don't have to disconnect any wires on it. Under the area where the coil assy was, is a BLUE elect plug with one wire jumpering from one socket to the other on it. Remove that BLUE connector.

Find the Black/White wire on the connector the Blue jumper was connected to. Now get a two/three foot piece of elect wiring bare at each end. Put one bare end in the socket where the black/white wire is. Check for the car being out of gear. Now touch the other end of that new bare wire to the positive post of the battery.

The starter should have turned over as long as the wire was held to the batt positive post. IT should turn over each and every time you touch it to the positive post. IF it does, to me, that indicates a problem b/t the connector the blue plug as on, to the ignition switch. There is a clutch interlock switch inbetween also.

So if you don't get the click, but the starter turns over each time you touch the wire to the batt positive post, it ain't the starter or the starter solenoid imho. It's also a good way to get the car started if your key won't work when going to Start. Just have to have the key to ON for the engine to actually run though.

Gotta get some glasses. Key word today: not.

The above accounts for the click and no starter action. Does not explain the engine turning over but no ignition. I'd say it's a tired starter and try a new/rebuilt one. Remember. If the starter is turning over too slow, each time it revolves it spits fuel in the rotors. Might cause a slight flooding condition aggrevated by the slow starter action. Flooding equals no starting.

I hate starter threads. It can be a number or things. I hate parts swapping to fix things. Money down the drain.

It takes a max time of a half hour to pull the plug in the jpg attached, and jumper batt voltage to the black/white wire in the connector the BLUE jumper was attached to. The black/white wire will be opposite one of the sockets the wire on the BLUE connector goes to.

The terminals are a bit beat up so I got terminals from advanced auto. I will keep you updated on the results.

It's like this. If the battery cables were the problem it's easy to find out. Turn the headlights up and on. Look at the headlights as the key is put to START. IF you hear the same click, but the headlights stay lit up, then it's not the battery/battery cables ets. It's either the start circuit or the starter solenoid or starter brushes.

Takes all of ten minutes to check that out.

First, clean your battery posts/replace terminals if they're bad.
Secondly, clicking and not turning over is a starter solenoid 99% of the time. Reason being that if it was the ignition switch bad, it wouldn't click.
How are you sure it's not getting Fuel/Ignition while turning over, have you checked that the injectors aren't toggling and spark isn't there? No fuel and no spark can be a CAS problem, or a faulty relay.
So, even at a stop, at idle, with the clutch fully in, when you shift in 5th the car dies?

Yeah. As soon as I switch it to fifth gear it dies. I don't even I have to fully engage the gear.

This thread seems to be a one way conversation.

Farm it out to someone that knows what is going on.
