while you are on the topic of the little male connector. Old Japanese cars often need a little modern pick me up here to take load off iginition switch

 

So, a 30 or 40A relay with a built in fuse in its front joey pocket be good.

Run nice fat wire from battery POS to 30 on relay

The female wire black/white trace goes to 86, instead of to starter solenoid from now on in

Wire 85 to a reliable earth

Nice fat wire, black with a white trace if you score one from a wreck from terminal 87 to the male spde on the starter solenoid

 

This set up means power from ignition is not loaded up with starter solenoid power, just light load to switch across 86 to earth 85 holding coil to bridge the heavier wire from battery to starter solenoid

 

This may fix your problem or prevent from occuring at a later stage

Some of the common automotive general purpose relays have standard numbers on the terminals.

Joey pocket what? 30 relay and What's 85 or 86?? Sorry man but your instructions are confusing as hell ha. I have no idea what any of that means . I'm still wet behind the ears when it comes to cars so can you please try and explain that one more time . I appologize for my ignorance when it comes to these things but I am extremely grateful to all who have put any time and effort into trying to help me out on here

I think the numbers may be a Bosch thing copied by many that make aftermarket auto "horn relays"

So each time you hook one up you look for the tiny numbers cast in the underside easily seen by youthful eyes

A useful website is www.the12v.com has lots of auto electrical tips n threads. Whenever a relay is involved they use these numbers

Get any relay attach 12 pos to 86 terminal 12 neg to 85 terminal and you will hear and feel a click inside.

There is a coil of clear insulated wire inside. When you give each end of the coils leads or terminals pos and neg power you created an electro magnet. This attracted part of a switch on a bendy piece of spring metal that then switched a circuit capable of carrying a heavier electrical load..

The joey pocket is as in kangaroo joey pouch pocket

Some relays have a socket in their front to take a blade fuse. Cist more but you can find its fuse easy and quick. No extra wires and connections for an inline fuse

Where do I find the 85 and 86 terminal?

Cranking but won't start . Haven't tried the rewiring trick yet. The oil pressure gauge is either not working or it has no oil pressure . I can't hear the fuel pump go on either and the gas gauge says I'm empty but I just put like half a tank in . Idk if they're related or whatever

Oh and the male spade thing on the starter .. What's that supposed to be reading ? Cause while the keys in it or in the on position it isn't reading any voltage at all ..

The small connection on the starter is the solenoid coil. The ignition switch applies 12v to it when the key is in the start position. Otherwise, it is open cicuit.

If it's cranking reliably, you don't need the relay mod yet.

Well the solenoid coil is reading zero.. With the - side to battery - and the + side probing the little spade it doesn't read a single thing .. No matter what position the key is in

The voltage comes from the wire from the igntion barrel when in the start position only. The solenoid does not give voltage.

You need to test the wire from the ignition. But if you've already got it cranking this test is redundant.

You now need to look at spark - coil, dizzy module if it's got one (being an '85 it won't have the optical gear in it). Check the coil and replace if needed before going and replacing the module ;)

Ok so I rewired the fuel pump and it works now . on a kill switch but it works . Pulled the dizzy cap off and the rotor isn't spinning while I'm cranking the engine . Whaaaat now?

I think I recall someonbe saying there is a list of things YOU need to check do replace ...before expecting reliability out of these great old dinosaurs

I don't recall . And not for lack of paying attention . I believe Miles Fox has videos on the timing belt procedure up on YouTube. Is that my next move?

remove the outer black plastic cover on the distributor side.  see if the belt is broken.

 

There are lots of threads on here, and videos on youtube of how to replace them.
