On my 90 740gl it is right next to the ignition coil. It depends on the ignition system used. On a Regina ignition, I think everything is built in the coil (The big square one) The regular round coil is for BOSCH ignition and a separate module is use. NOT SURE, would appreciate confirmation.
In the 1989 Volvo 740 GL with a Bosch system it is located just above the steering column on the dash.
What are you looking to fix. I am a Volvo tech. 89 Volvo 740 turbo runs rich blows black smoke all plugs are black but are not oily rev it up change plugs. wires. coil. air filter.
On a Regina ignition (to identified check the ignition coil, it's a big square one) if i'ts your case, the sensor is a Air temperature sensor (locate close the air filter)

How do you replace a fuel pump for a 1998 Chrysler Sebring Lxi Coupe ?
You need to replace it. There are 2 screws that hold it on.

Yes. The 740 and 940 are very similar and share many common parts.
I don't have the pinout, however you can put your fingers on the relay, put the ignition on you must feel a click at the fuel relay coil. However, the contacts relay are maybe defects, if you have a doubt change it. It's maybe 20$. Be sure about fuses.
