Just to update those who assisted me with my intermittent start problem. I pulled the fuel relay and got the cover off in no time. I almost asked the group where I was to find this relay, but its difficult to miss! It all looked great in there at first glance. A little closer looking did show up some minor cracking around one of the relay connection solder joints to the PCB. The clincher I think tho (hopefully) belonged to the rivetted connection of the conductor plate to the back of the pin labled terminal 15 (live at ign on). It showed some signs of duress and copper verdigree. I wondered what lurked under the rivet head and the blade of the connection, so I decided to clean up what I could see of the part and solder that too. All the other rivetted plates to a man looked perfect, so I left them alone. I WD40'd the relay base before re-inserting it. To date I have had no further re-ocurrence. Fingers crossed. BTW, there is a PIC microcontroller IC in there. Pretty advanced for
1989. Must have cost a fortune then.Cheers... Rob.
