temp gauge issue porsche 924

[baggabones]

Sorry if this is a bit long winded.....been having hot start issues recently with my '81 924, even with the "hot start switch set up".a
Anyway, decided to replace the cold start injector and sort bodged PO wirning to it. No difference


Anyway since doing this my temp gauge is showing past the the top of the red mark....fan working as it should and engine doesn't appear to be hot. Am I correct in thinking this may be an earth issue? Could it be connected to what I've done (guessing it must be, or one hell of a coincidence?) Thoughts and advice please? Thanks

If you have a wiring diagram would check to see if they both run off the same earth point first

Will check the haynes later, seems weird that all did was put new spades on and connected up the new injector?.......unless I wired it up backwards???....mmm....there's a thought.

This simple rewiring is becoming a complete bloody nightmare now ....been back on it, now my fuel pump wont run ....going to recheck all my fuses later.

Really feel for you 924 electrics can be a little tricky
This is what i had to face after my loom melted due to the PO bodgery!!! ,luckly all sorted now.
Wish i could help you but without seeing it its hard to sort ,but sort out those grounds and add more.

Quick update, rewired the fuel pump relay, put new connectors on the temp sender on the top of the radiator.....all is is now good! however I still need to rectify the hot start switch issue but at least we're up and running again all be it with an embarrassing half a dozen cranks on the starter when hot
