Hi all,

Just trying to figure out which relay is which around the fuse box. In particular, looking for the fuel pump relay.

Despite driving out an old tank of gas (with added dry gas, and cleaner), refilling, and some more driving, my car seems to cut off totally (exactly as though it ran out of gas), somewhat randomly 'when warm' and in particular, when trying to start the engine warm.

Has happened at a stoplight or two, and once at highway speed. Has not happened when car is started first time for the day or after a few hours of shutoff. Have verified good spark when the warm 'no start' occurred, and no 'vaccuum' in the gas tank.

When running, seems to not miss a beat otherwise (kinda indicating that I'm getting decent fuel pressure when I get it).

tapping (all) of the relays has resulted in the car starting immediately (once I'm back in the car of course). done that 4 times now, car starts immediately.

thanks again for any info!
andy
p.s. what's a good recommended manual for the car. Seems I'm getting to know a lot more about it lately:-)
