Re: Ur-q fuel pump and wrong Duty with new Ox sensor.

[Martin Pajak <quattro@rogerswave.ca>]

Phil,
Thanks a lot.
It's a D.

They gave me the correct relay allright.  I was worried cause it was only
$15, little too cheap for an Ur-q  : )
Wire from MAC is good and ground for the relay is there too.

So why won't it run with the correct relay.
The pump will run with a regular '85 Coupe Relay that does not use the
MAC's output.
This is the relay that the car came with BTW.

Ichecked the voltage at the MAC for fuel pump output (pin 16) and it's fine
when the ignition is on.
Once you start cranking it goes to 0.

BTW I replaced the Oxygen sensor (with brand new) and no difference on Duty
cycle (still at 96%).
Coolant sensor is O.K. (1 kOhm at room temp) and wire is fine too.
