jono Posted January 8, 2018 Share Posted January 8, 2018 (edited) 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 Edited January 8, 2018 by jono Quote Link to comment Share on other sites More sharing options...

DaveT Posted January 9, 2018 Share Posted January 9, 2018 Some of the common automotive general purpose relays have standard numbers on the terminals. Quote Link to comment Share on other sites More sharing options...

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 Quote Link to comment Share on other sites More sharing options...
jono Posted January 11, 2018 Share Posted January 11, 2018 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 Quote Link to comment Share on other sites More sharing options...

Jaysus Posted January 13, 2018 Author Share Posted January 13, 2018 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 Quote Link to comment Share on other sites More sharing options...
Jaysus Posted January 13, 2018 Author Share Posted January 13, 2018 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 .. Quote Link to comment Share on other sites More sharing options...
DaveT Posted January 13, 2018 Share Posted January 13, 2018 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. Quote Link to comment Share on other sites More sharing options...

Jaysus Posted January 14, 2018 Author Share Posted January 14, 2018 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 ..

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 Cheers Bennie Quote Link to comment Share on other sites More sharing options...

Jaysus Posted January 19, 2018 Author Share Posted January 19, 2018 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? Quote Link to comment Share on other sites More sharing options...

Jaysus Posted January 20, 2018 Author Share Posted January 20, 2018 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? Quote Link to comment Share on other sites More sharing options...
DaveT Posted January 20, 2018 Share Posted January 20, 2018 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. Quote Link to comment Share on other sites More sharing options...
Jaysus Posted January 23, 2018 Author Share Posted January 23, 2018 Redid the timing belt and it fired right up! But it dies unless I keep pumping the gas ha . Radiator has a hole in guessing cause it's running out of water fast and it's smoking and sizzling but can't really tell where from . I'm just pumped it fired up! Haha 1 Quote Link to comment Share on other sites More sharing options...
el_freddo Posted January 24, 2018 Share Posted January 24, 2018 Did you do the one crank rotation between fitting each belt? I didn't do this back when I was learning about these engines and while it ran, it wasn't much fun and didn't like to idle. If you lined up the three marks and installed both belts, you'll need to line up the three marks and the cam mark, remove one belt and rotate the crank 360 degrees and reinstall the cam belt as per alignment procedure. Then re-tune the timing I know the hotwire AFM needs 20 deg BTDC static, I'm not sure if this is correct for the flapper AFM setup as I never played with these.

DaveT Posted January 24, 2018 Share Posted January 24, 2018 Get the cooling system leaks fixed before you run it for any length of time, or you will be needing head gaskets also. Yes, double check the timing belts, especially the 1 rotation between installing the first and second belt. Quote Link to comment Share on other sites More sharing options...
Jaysus Posted January 24, 2018 Author Share Posted January 24, 2018 I did the rotation between the first and second belt . And how should I wire up the fuel pump? Cause right now it's wired from the + battery post to the + side of the pump(15amp circuit in between battery and pump on + side) and from the - battery post to the - side of the pump ha . Seems like it's drowning it or something idk Quote Link to comment Share on other sites More sharing options...
Jaysus Posted January 24, 2018 Author Share Posted January 24, 2018 I have a bosche timing light I just got . Never used one before so any pro tips on setting the timing with it? Or is there a better way? Quote Link to comment Share on other sites More sharing options...
