92 Nissan Stanza stalling

1992 NISSAN

I have a '92 Nissan Stanza with 277000 Km and a 2.4L 5 speed. I have been having a problem where it will start and run fine then for no apparent reason it stalls. It may or may not start right away, but will eventually stall on it's own again. I have replaced plugs, cap, rotor, plug wires, fuel fillter, air fillter, coil and resister. The fuel pump was replaced by the last owner (within 2 years), all the fuses and relays are OK. The ignition switch is OK. The Nissan dealer is saying that it is a wiring harnes issue, but when I check over it I can't find any problems with the harness. I have seen many questions on other sites that say the same thing, yet there is no clear answer. Any help will be greatly appriciated.

When it stalls, disconnect a plug wire and ground it while cranking it over look for spark-do you have spark? No spark check the ignition relays at the fuse/relay box left side of dash-looking at it they'll be 4 of them-its the 2nd and last one-2 ign relays.

Got spark check for fuel.

Thanks I will check the relays. Sometimes I get a spark sometimes I don't. I've been checking for spark right at the coil. It seems to be intermitent. When it won't start there is no spark, when I get a spark it fires right up. When the car sits with the key 'on' the fuel pump kicks in and I can hear the fuel pump relay, then as it sits the relay starts clicking randomly sometimes producing a spark at the coil (which I can also hear in the dist. Cap) all while the car's not running. I was told to check the fuel pump as it may be grounding out and sending a feedback singnal which may shut everything down but so far I see no problems there. For now I will go check the ignition relays at the fuse/relay box. Thank you again.
