hi jon
story so far
1) Ensure ignition is OFF.
2) Remove rear of ecu plug cover and insert plug back into ecu.
3) Turn ignition back on (do not start engine)
4) MAIN POWER CHECK: Check for DC voltage of at least 11.5V between ecu pins 19 and 20. = 13.17VOLT DC
5) REFERENCE CHECK: Check for DC voltage of around 4.8 to 5.2V between pins 11 and 30. = 4.95VOLT DC
6) MAP SENSOR CHECK: Check for DC voltage of approx 1.8 to 2.5V between pins 11 and 15. = 2.14VOLT DC
7) THROTTLE CLOSED:
2WD: Check for DC voltage greater than 4.5V between pins 11 and 17. = 4.78VOLT DC
8) THROTTLE FULLY OPEN:
2WD: check for DC voltage less than 0.5V between pins 11 and 17. = 0.6 VOLT DC
9) Turn ignition off, unplug ecu, and turn ignition back on (don’t forget immobilizer if fitted)
10) CRANK SENSOR: Check resistance between pins 3 and 4 between 300 and 1200 ohms. = 667 OHM S
11) CRANK SENSOR: Check AC voltage on pins 3 and 4 while cranking engine - should be at
least 2V. = 0.02 VOLT AC (MAY HAVE A PROBLEM HERE?)
11) PHASE SENSOR: Check resistance between pins 5 and 23 between 300 and 1200 ohms. = 778 OHM S
12) PHASE SENSOR: Check AC voltage on pins 5 and 23 while cranking engine - should be at
least 1.5 - 2V. = 0.4 VOLT AC ( COULD HAVE PROBLEM HERE ?)
12) INJECTOR: Check resistance from pins 18 to 20 should be 2 to 5 ohms. = 3.2 OHM
13) INJECTOR: Check resistance from pins 35 to 20 should be 2 to 5 ohms. = 3.2 OHM
14) INJECTOR: Check resistance from pins 33 to 20 should be 2 to 5 ohms. = 3.2 OHM
15) INJECTOR: Check resistance from pins 32 to 20 should be 2 to 5 ohms. = 3.2 OHM
NOTE: INJECTOR TESTS MAY NEED MAIN RELAY ENERGISED ON L1 and L6 ecus (link pins 1 and 10 first)
16) IGNITION TRIGGER: Read voltage between pins 24 and 25, should be at least 4.5V. = 0.2 VOLTS DC ( PROBLEM ??) unless you mean measure when i try and start the car ? this is measured when ignition is turned on?
18) Place a temporary wire link from pin 1 to pin 10 (energises ecu power relay) - you should hear a click. (NO CLICK HEARD)
19) Quickly link pins 19 to 28 to test fuel pump runs. (TESTED OK)
20) COOLANT TEMP: Check resistance pins 29 and 11 for 800 ohms to 5000 ohms (depends on temp) = 880 OHM S
21) CHARGE TEMP: Check resistance pins 31 and 11 for 800 ohms to 5000 ohms (depends on temp) = 886 OHMS
looks like all is not as it should be with number 11 , 12 , 16 ,and 18 ??
tdc gap and phase gap , and test 17 will be tested tommorrow plus comp test as long as it turns up . so ill get these done
cheers ant
