Thermostat Ground questions
I'm hunting issues with my thermostat ground.
p28 ecu
I believe there are 4 wires attached to t-stat ground.
What are the wires that run to the thermostat ground?
What are the ECU pin numbers (obd1) that these wires lead to?
What color wires lead to t-stat ground?
Are the fuel injectors grounded here too?
Thanks guys

Re: Thermostat Ground questions
Thermostat grounds are for the ecu and main relay. They go to the ecu a23,24,a26 and b2. The injector grounds only go from the injectors to ecu.
What problem are you having?

Re: Thermostat Ground questions
I believe the thermostat ground was relocated by previous owner, there are no wires attached at factory t-stat ground location.
Car cranks, won't start, spark plugs are dry after cranking, not getting fuel to injectors, but have fuel at the rail and maintaining adequate fuel pressure.
I want to run new ground wires from thermostat ground to ecu and was wondering to which ECU pins.
You mentioned 3 pins, but there are 4 wires?

Check to see if your getting 12 volts at the ecu a25 an b1. Before replacing the grounds.
