Other day car comes to abrupt stall, no warning, good crank. Checked spark, t-belt, opened fuel rail , no fuel pumping. Jumped 4 & 6 starts right up.

Crank sensor wire intact but 8 years old. I think it means relay, ECU or wiring. Swapped likely good relay

On the relay per Blue book, voltage at 87/1 (Big orange wire) nothing at 87/2 (yellow red wire). Voltage at 30. Some confusion as Blue Book says check voltage at 86, but there are 2 86's. No voltage at 86/1 but yes voltage at 86/2. both relays likely good. Any clarification?

On to ECU. Yes pink label 951 with no signs of repair, so original? I have a white label 951 from fully functioning 92 240 so I'm confident it is good.

Ready to make the swap but thought I would request input. Should I perform any tests on the pink ECU? Am I missing another possibility?
