I am picking up a complete setup from a 1988 Iroc and want to make sure I get all of the sensors. If you could tell me what the connector looks like that goes with the sensor that would help also

Thanks

 

Ok... off the top of my head.. here we go

MAF or MAP
TPS
Crank Position
Air Temp
Coolant Temp Fan
Coolant Temp Computer
Oil Pressure
Oil Sending unit (may be both in one)
Knock Sensor
O2 Sensor
VS Sensor
EGR Sensor? (forund this one when I took the Plenum off)

Input Devices

IAC Valve
Injectors of course
Two Ignition Coil Connectors and Two Distributor Connectors
Fuel Pump

Any I missed guys?

Do the tpi's actually have a crank position sensor, I did not think that they did. Where is it if they do. Thanks.

 

i doubt that they have a crank postion sensor. i thought only v6's had that sensor...

Good point.... Then there must be a sensor in the distributor that tells the computer where the engine sits (timing)

I couldnt say for sure but I believe that it is used on mpfi cars so that it knows when to fire which injector and whatnot.

TPI has batch fire injectors
No crank sensor...

 

I knew it was batch fire and was pretty sure it didnt have a crank sensor, but I wasnt sure what it was used for but like I said that is what I would have guessed.
