The problem is NOT your ecu, the ECU has nothing to do with the gauge in your cluster and it gets it’s temp info from a different source (see below). Are you sure you replaced the correct “sensor”?

There is an ECT “SWITCH” which activates your cooling fans.
There is an ECT “SENSOR” which gives info to your ECU.
There is an ECT “SENDING UNIT” which tells your gauge what it should read.

ok i will get another temp (gauge) sensor and see.
and if still nothing i guess the cluster i have 2 get…

but now i got a bigger problem

the teggy wont start is floding (fuel) i disconnect the injectors and it starts for like 3sec or so.
i plug them back in and crank and no start and could smell the fuel!!!
i took the plugs and the tip where black and soak on fuel!!! got a new set and still doing the same thing!!!

thanks for all the help

I’ve encountered that problme before.

Helped a buddy do an auto to 5 speed swap on his 98 civic.

Hes was bad, the fuel literally started leaking out the intake mani.

The solution and problem was a BAD ECU.

So i would throw one from someone you know tat has a good ECU and see if the problem persist.

I dunno about the main relay, could be a possibilty.
Something worth checking out
