i disconnected my battery today to reset the ecu, then after re-connecting it, i seem to have power to everything, but the starter motor isn't doing anything, not even a click from the solenoid.

there is 12V going to the starter motor, and i even swapped it for another RB25 starter motor with no luck.

i have a feeling its the smaller wire that attaches to the blade terminal that is giving me problems...

what does this wire connect to at the other end? i chucked a multimeter on it, and i assumed it was an earth but i got no reading for it whilst trying to start the car...

this is an RB25 in a HR31 if it matters too..

get someone to tap the starter with a hammer as you turn the key (read here: TAP the starter motor, not slam the FK out of it), if it suddenly starts turning over and starts, you have a dicky solenoid in your starter motor, time to go and get a new one.

I had similar in my previous car, ended up having to rig an under the bonnet trigger wire for the starter so I could start the car when I was on my own (until I could source a starter motor and have it rebuilt).

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
