Hard start and a bit lean

I have an issue kind of similar but not quite the same. My '87 has the 4 cylinder engine and will have the up and down idle but that usually occurs after it has warmed up. I've had people suggest checking the idle air control passage and fuel pump pickup as possible sources for this issue. I haven't gotten around to fixing it though. My engine also usually runs rich rather than lean at startup. My guess would be fuel related. Might be the fuel pickup needs replacing as they can wear away over time. Also would be worth checking your injector spray. Make sure it's a nice even cone and that it's not clogging some or spraying more to one side. I would also check the fuel filter.

The fuel pump should run for 2 seconds when you turn the key on (you should hear it run as it is controlled by the computer for 2 seconds at this time). After the engine starts the oil pump switch closes the circuit and the fuel pump operates. Check the fuel pump computer operation by using a test light at the ALDL connector, connecting terminal A at top right and terminal G at bottom left. If the test light does not stay on for 2 seconds, it is the computer.
