Very unusual situation!!

[aca152]

Ok, ill try to make this quick and to the point, i can't figure this out!

-Bought a stealth turbo (stock) a few years ago.

-always had idle problems when warmed up

-seller told me it was because of a bad engine temperature sensor

-did research, found it could be ISC or Boost leak

-Made boost leak tester and fixed major leaks

-With lack of knowlage of this car I stumble but fixed the following: timing belt, transmission, serpontine belt, ac display, ac compressor, cruise control unit and stuck throttle cable, oil cooler. and a few misc things because it need this.

-I changed the coolant GAUGE sensor thinking it was the Engine temperature sensor. (later realized this they were 2 different things)

When I did this the car will not start. Very confused thinking this does not affect the starting of a car, just the temp gauge right?

anyways, with everything togeather i reach in there and unplug it. crank it over a few times and IT STARTS!! While its running I plug it back in, the car stays running. As soon as I shut it off and try to start it again it wont fire!

**I HAVE NOTICED WHEN UNPLUGGING GAUGE SENSOR WHILE OFF I HEAR A CLICKING NOISE LIKE SOMETHING IS MOVING LIKE AN A SMALL MOTOR FOR A VALVE OR SOMETHING??**

I hope this is something simple that im overlooking and not a bad ECU, ISC

Thanks for your help anyone

Check your ECU caps, almost all of our ECUs seem to blow caps.
If so contact Rymer (+numbers plz correct) on here he's the best and cheapest ECU man.
Also, check your ECU codes, computer will tell you what it is unhappy about.
Have a great day and I hope this helps.

The sensor you got is wrong. Put the old one back in. READ THE MANUAL and test it to make sure it works properly.

Parts stores VERY often mess up part number of sensors. Many of them look alike, but function differently.

Since you fixed your leaks the next thing to fix your idle is the IAC.
