Cold start trouble
'88 IROC L98/700R4
When the engine is cold it wont start on it's own. It will with a squirt of ether. When warm it starts but takes a second. There is 12v at the cold start switch connector when cranking. There is no voltage at the cold start injector when cranking. I would think the switch is the cause but I cannot source one. What are other options? Non cold start ECM?
Also, what controls the priming of the fuel pump? When I turn the key to "run" I don't hear the pump prime. Turn to "start", then to "run" and I can hear the pump.
