How many fuel pumps and relays are on a '90 volvo 740 GL

You may have to bend the conections on the fuel pump relay, so they fit tightly. Try gently twisting it l/r, while turning the engine over.
Hope that's it.

You don't give any details about the vibration, you know what "strange" means but the rest of us have to make a guess.

The most likely cause is that the wheels are out of balance. This can happen if you've recently struck a kerb or pothole, if an existing balance weight has fallen off, if you have recently removed a wheel and refitted it, or if you've had a tyre repaired or replaced without having the wheel rebalanced afterwards.

There are many other potential causes, but getting the wheel balancing checked and adjusted is the cheapest and easiest thing to start with. Get the balancing checked and then report back if the problem is not resolved.

Please don't forget to rate my answer.

Chilton or Haines publishes manuals for the 740. Of the two, the Haines offers more direct parts removal and replacement info. The Chilton has too much generic filler. Get either on Ebay for less than $20.

Go to an auto supply store like PEP boys or Advance Auto, etc., and buy a Haynes Repair Manual for the 740. You may be able to consult one at your local library for free. Even if it doesn't cover your model year, the replacement instructions are pretty much the same for all years. in fact even a 240 Volvo manual would be essentially the same. Pay particular attention to the installation instructions....you have to slide the pump on, and then rotate it a few degrees clockwise to make the upper o-ring seal. Good luck!
