Where are the following Items? I cant Find it in my Haynes Manual
engine coolant temperature sensor
manifold air temperature sensors
coolant temperature sensor.

I had a shop install a Merzier WP into my 1994 Z. Prior to install i just installed a Delteq, Ran like a Top!! Love that thing! Anyway i took it back to the shop for the Merzier, got it back, felt like it was running "heavy" vs after installing the Delteq, it felt Light. Now in the past few days since getting it back from the shop, the engine feels heavy, once the engine is hot and turned off, you cannot immediately start it up, it acts as iff there is no fuel going into the engine. If i wait 20 minutes or so, Boom starts up. I thought it was the fuel pump but that seems to be working fine. It was suggested to me to check those sensors because they may not have been properly connected by the shop after the Merzier Install. Help any one?

 

engine coolant temperature sensor - This should be the on the waterpump housing. (and goes to the ECM)

coolant temperature sensor - This is the one in the driver side head. (Goes to the gauge on the dash)

manifold air temperature sensors- I would guess this is the IAT or inlet temp sensor which is mounted in the intake elbow.

 

Go here-- Best info on the net.

Thanks A Million!!!!

 

Might want to reorganize that sig. There is a 5 line limit...

 

DOOOOOOOOHHHHH!! I lost Count at three????

I had to take the Z into the shop, looked like all Sensors were Hooked up correctly. Still tries to start but acts as if it's flooded. Sure cant wait to find out what this was.

Thanks for everyones help, it is always greatly appreciated

 

maybe it is flooded?

 

Just because they are hooked up doesn't mean that they are working. Scan it with the car on. If the coolant sensor says -40 degress or what ever, there's your problem. Same thing happened to mine. The plug ion the sensor barely came out of the plug.

 

From an Over night sit with out any cranking? I didnt think so, might be a fuel pump problem or injectors? we'll see what the professionals think
