Measure the resistance of each fuel injector.
Is the resistance within the value specified (the resistance
will increase slightly at higher temperatures)?
Replace any of the fuel injectors with a resistance out of
specification.
Is the repair complete?
Check for open or short in the wire between fuel injector
harness connector terminal 1 from all of the fuel
injectors and OVPR connector terminal 6 and repair as
necessary.
Is the repair complete?
1. Check for an open between the fuel injector 1

harness connector terminal 2 and the ECM
connector terminal 63.

2. Check for an open between the fuel injector 2

harness connector terminal 2 and the ECM
connector terminal 64.

3. Check for an open between the fuel injector 3

harness connector terminal 2 and the ECM
connector terminal 65.

4. Check for an open between the fuel injector 4

harness connector terminal 2 and the ECM
connector terminal 66.

Is the problem found?
Repair the open fuel injector harness wire(s)
Is the repair complete?

Test Description

The number(s) below refer to specific step(s) on diag-
nostictable.

3. By performing a compression test, it can be deter-

mined if the engine has the mechanical ability to
run.

9. It is important to check for the presence of spark

from all of the ignition wires. If spark is presence
from one to three of the ignition coil terminals, the
Crankshaft Position (CKP) sensor is OK.

37. The replacement ECM must be reprogrammed. Re-

fer to the latest Techline information for reprogram-
ming procedure.

39. This step checks for proper operation of the Engine

Control Model’s (ECM’s) control of the fuel pump
cir-cuit.

58. This step checks for a ground signal being

suppliedby the ECM to operate the fuel injectors. If
there isno ground present during the cranking of the
engine, and the fuel injector wiring is OK, the ECM
is at fault.

Caution: Caution: Use only electrically insulated pliers when handling ignition wires with the engine running
to prevent an electrical shock.

Caution: Do not pinch or restrict nylon fuel lines. Damage to the lines could cause a fuel leak, resulting in
possible fire or personal injury.

Perform an Euro On-Board Diagnostic (EOBD) System
Check.
Is the system check complete?

Crank the engine.
Does the engine start and continue to run?
Perform a cylinder compression test.
Is the cylinder compression for all of the cylinders at or
above the value specified?
Inspect the timing belt alignment.
Is the timing belt in alignment?
Align or replace the timing belt as needed.
Is the repair complete?
Repair the internal engine damage as needed.
Is the repair complete?
Inspect the fuel pump fuse.
Is the problem found?
Replace the fuse.
Is the repair complete?
Check for the presence of spark from all of the ignition
wires while cranking the engine.
Is spark present from all of the ignition wires?
1. Measure the resistance of the ignition wires.
2. Replace any of the ignition wire(s) with a resistance

above the value specified.

3. Check for the presence of spark from all of the

ignition wires.

Is spark present from all of the ignition wires?
