Diagnosis & Repair

  1. Turn ignition off. Access ECM behind glove box. Using DVOM, measure voltage between ground and terminal No. 2 (White/Red wire) at ECM E6 connector. See Figure. If voltage is 9-14 volts, replace ECM and retest. If voltage is not 9-14 volts, go to next step.
  2. Remove and inspect EFI fuse. EFI fuse is located in engine compartment fuse box. Replace as necessary. If fuse is okay, inspect circuit between EFI fuse and ECM. See appropriate wiring diagram in WIRING DIAGRAMS article. Repair as necessary.
