Hi guys,
my dad had a bit of a 'barn find' last weekend. He bought a highly spec'd Uk 1994 1.8 Mk1 with only 36k on the clock. The owner had a bit of an accident in it about 10 years ago and parked it up in his garage and never went back to it.
Anyway we collected it last weekend and my dad went about getting it up and running. When we get it back to his we tried a fresh battery in it, it would turn over but wouldn't start - turns out it had an immobiliser fitted and the guy we bought it off had gone and lost the fob to disarm it. We traced it all back an un-wired it so now it's up and running.
The only problem we now have is the temperature gauge isn't working. It gets upto temp and the fan comes in and out like it should be no gauge.
I down loaded a manual via here and it seem's it's only for the early 1.6 model as that show's the temp sender mounted in the thermostat housing on the front of the engine. This engine has a totally different housing on it and there is no evidence of a sender ever being there.
We've found the sender that is on the back on the engine under the coilpacks & CAS unit. That has a green plug and 2 wires going to it but I think that ones is for the ECU. Is it possible that the later mk1 1.8 just has the one sender? Could we have disturbed the wiring when we were stripping the immobiliser out going from the ECU to the gauge??
Any help would be greatly appriciated as i'm reluctant to start putting the car back together until we've got this issue sorted.
