1985 Toyota Corolla 4 cyl Two Wheel Drive Manual

Have a 1985 Toyota corolla 4age. Car starts for 4 seconds bit then shuts off. I have checked timing, spark, replaced fuel pump, checked for vacuum leaks also replaced the air flow sensor. Don't know what else to check.

Check the Auxiliary Air Valve (Idle Speed), EGR and PCV valves and recheck the fuel pressure.

Also check the choke opening and fast idle cam adjustment- A/F mix and curb idle speed adjustment

Just noticed the idling stabilizer amplifier is missing, would that affect the ecu.
