86 volvo hesitates/stalls problems

Hi i have a 86 volvo sedan gle and it was doing the same thing so i started searching and the fuel relay makes a click and as soon as it does that the car idles really rough, chokes and then dies so now my question is,
1. could it be the relay?- it get kinda hot but not hot enough to melt so im not sure if thats the problem.
2. the volvo has ''2'' fuel pumps one inside the tank and the other outside, could it be that one of the pumps is out? and the other pumps is taking on the strain for the other?
3. or just simply the fuel filter? has anybody ever have this problem????

Check the fuel pressure regulator. Its a vacuum assisted device that sits on top of the engine. Pull the small vacuum hose off the regulator and see if it is wet with gasoline. If so replace the regulator - AutoZone $60. Let me know.

I have a 1987 Volvo GLE that stalls (more and more frequently) and then starts (used to start immediately, but now it takes a while before it starts again). I am led to believe the relay for the fuel...

The light out warning if the lights are all lit means that you have mismatched bulbs in one of the circuits.
The problem with stalling could be a lot of things, including the fuel relay, as those are a common failure point. It would help if you could determine whether the problem was lack of spark or lack of fuel when the car fails to restart.
When the car is not restarting immediately, can you hear the fuel pump beneath the car spin up for a second when you turn the key to the on position? If not, take a paperclip and short between the two fuel pump fuses in the fuse box by your left foot. I think it was #4 and #6 but the fuse box cover will tell you. If that makes the pump spin up and the car start, replace the fuel pump relay which is under the dash above your passenger's right foot. If the relay does not make the pump spin up, then the ECU may be failing to provide a ground to the fuel pump relay, The ECU is behind the kick panel to the right of your passenger's right foot.

the firsrst thing to check is a FUEL-VAPOR LOCK and evap system esp[ecially the fuel cap and running the A/C can cause relays to get hot and check fuel pump relay and filther and last fuel pressure
