Also engine running is not stable in idle mode. Check ignition distributor Currently installed original distributor (from 4E-FTE Denso 229100-7631) Toyota /19100-11070 (SERA01 SERA02) has one connector 4-pin: 01 -> to ECU "G-" 02 -> to ECU "G" G2 03 -> to ECU "NE-" G1 04 -> to ECU "NE" and 5 connectors for high voltage resistive cords Distribution order goes: HV01 -> HV03 -> HV04 -> HV02 -> repeat cycle also may fit distributor Toyota /19100-11080 (SERA03) slightly modified by hand |

For more stable engine start on wet weather, need new high-voltage wire (ignition leads): CORD SET, COIL & SPARK, W/RESISTIVE /90919-21507 (or Blue Print ADT31668) , includes lost one /90919-13388 (missing this cord) Another high-quality cord: Magnecor KV85 HT. Replacements possible: OEK279, OEF378, OES1185, RC-TE52 NGK similar (variants) Old HV wire from coil was "6391-5200" with 12.4mm diameter rubber connector with 4.7mm diameter pin R=9 kOhm Basic update (SERA03 after 1992, needs replacement of COIL ASSY, IGNITION /90919-02197 and CAP SUB-ASSY, DISTRIBUTOR/19101-11080): /90919-21540 CORD SET, COIL & SPARK, W/RESISTIVE (or Blue Print ADT31669 or NGK RC-TE52 or Toyota 90919-21587) includes (lost one): /19590-11020 -> Used on Toyota STARLET (EP80,NP80,EP90,NP90) 4EFTE engines CORD, COIL RESISTIVE ? Other similar cord sets: Starlet /90919-22294 /90919-22373 (EL54 with 5EFHE) -> newest, but only 4PCs - because this distributor model has ignitor on itself -> Lorcen LC1433564, Avantech IL0104 5E-FE engines have /90919-22325 resistive wire 5mm^2 for spark plugs: C04 ~240mm (34cm total) C03 ~300mm (40cm total) C02 ~420mm (52cm total) C01 ~500mm (60cm total) C00 ~300mm (40cm total) * to igniter Target resistance for new cord is 0000012:0000006 kOhm

Purchased Spark (4pcs) Denso IK20 for replacement, gap 1.0mm wrench 16mm , torque 25N*m engine works more or less the same on these iridium sparks as with previous ordinary spark (platinum), it does not affect wet ignition malfunction, as expected, -> 2017 done but main high-voltage cord replacement fixed problem with wet weather /19590-11020 |

Igniter installed is COIL.W/IGNITER Toyota /19070-10020 (Denso 101311-6080) Vu - made by Toshiba COIL in this assembly is /90919-02198 Denso 029700-7100 12V with 2-pin connector and 1pin for high voltage wire 89620 IGNITER ASSY Toyota /89621-30010 (Denso 131300-1250) 125 (SERA01 SERA02) also fits /89621-12050 (SERA03, same as in EL44-DCPVH) replace 89621-12010 igniter has 5-pin connector: 01 -> to ignition coil 02 -> IG- to DIAGNOSIS port 03 -> to ignition coil and injector 04 -> to ECU "IGT" 05 -> to ECU "IGF" Need remake ignition parts, remove 5th wire (from coil to distributor) -> leave only 4 wire from distributor to sparks. A1. Solder coil directly to distributor B2. Get "direct" coils from EXZ10 (Raum) model with 5E-FE + position sensor "2-DIS" type C3. Get "internal" distributor coil model -> best for 5E-FHE from Cynos EL54-DCPVH, like /19101-11060 + /19235-11200 Near coil there is capacitor /90980-04079 2-pin 250/0.47.A. Other possible upgrade for Sera ignition (as found in original Toyota ??? Repair manual ???): this EL54 (Paseo ??? - Cynos ????) distributor+coil /19050-11011 (19050-11010) has no commuter inside, it is separate 5-pin igniter /89621-26010 on frame, but engine hat /11201-11030 and head /11101-19435 is the same as for EXY10 5E-FHE engine, but camshafts are "newer" than for EL44 (different part number) for the same model 5E-FHE engine (do not confuse with 5E-FE camshafts, which are smaller). C-55 igniter 5-pin connector (similar): ? 1. ECU ‘IGF’ (Grey-Black) output signal 2. ECU ‘IGT’ (Light Green-White) input signal 3. "IG2" ignition +12V from switch-relay (Black-Red) 4. Diagnostics Socket ‘IG-‘ (Black) 5. Pin 2 on ignition coil C-56 connector (Black-White) C-56 coil (under igniter or distributor) 1. "IG2" ignition +12V from switch-relay (Black-Red) 2. Pin 5 on igniter C-55 (Black-White) AC + high-voltage wire C-72 distributor 1. ECU ‘NE’ (White-Blue) + 2. ECU ‘G1’ (Orange-Blue) + 3. ECU ‘G2’ (Blue-Green) + 4. ECU ‘G-‘ (Blue-Yellow): NE- and G1- and G2- + high-voltage wire , separate
