We've had several times when one of our older Volvo 240's stalled or wouldn't start because one of the fuses in the inside fuse holder wasn't making good contact. It doesn't happen anymore because I have cleaned them, tightened the fuse holders and coated the fuses and holder clips with a thin layer of silicone grease. These were older than your 240 but maybe an '87 could have this problem too.

2 things you can check in 30 seconds are the inline 25A fuse near the battery, look for corrosion etc... and, remove the oil filler cap and crank the engine, does the cam move?? If not then broken timing belt.

Some other things... can you hear the fuel pumps whir when you turn the key? The fuel pump relay will not 'pull in' unless the you are getting spark. So, what looks like a fuel problem could actually be a spark problem. A common no spark problem is the crank position sensor. I have also had to replace a power stage in an '87 740. Good luck....post your results.

I would check the inline fuse on the drivers side, near the firewall. The fuse melts under the cap and cuts off fuel. Sometimes it will make contact, sometimes not.

Good Luck
