Diagnostic Procedure 12 — Engine stalls when cold
1
Check fuel pressure. CONSULT method: Start engine. With "WORK SUPPORT" showing on display, eliminate fuel pressure using "Fuel Pressure Removal." After stalling engine, crank engine two or three times. Install fuel pressure gauge and check fuel pressure. Fuel pressure during idle: Approx. 245 kPa (2.45 bar, 2.5 kg/cm², 36 psi). No-tool method: Start engine. Remove fuel pump fuse to release fuel pressure. Install fuel pressure gauge and check fuel pressure. Fuel pressure during idle: Approx. 245 kPa (2.45 bar, 2.5 kg/cm², 36 psi)
N.G.
Check fuel pump and circuit. Refer to "Fuel Pump". (See page EF&EC-155).

Check injectors. Stop engine. Remove distributor. (Do not remove crank angle sensor harness connector.) Remove power transistor connector. Turn ignition switch to "ON". Check to ensure each injector emits hissing sound when crankshaft is hand-rotated. Display shows an erratic indication during self-diagnosis and does not show abnormalities.
