This is my first post. Be gentle.
I have a 1990 245 that died at the end of my street. It had done this sudden death thing twice before, but eventually would start again.
Now it will crank but not start. This is what I have done:
Checked for fuel - yes fuel is getting to the rail, relay is working
replaced CPS- no change, but i have some new scars on my hands
Test coil across terminals 1-15= 1.2 ohms terminal 1 and centre= 7.2kohms
replaced ignition switch
tried several ignition amplifiers
got a bentley manual and:
check for power to the control unit: check for battery voltage on ECU connector terminal 6 with ignition on = 0.13v
I'm assuming when checking for battery voltage I am looking for 12v?
If any faults are found, check the wiring. Where?
check for ground between the ECU connector terminal 14 and ground (ok), and 20 and ground (nope). checked 2 ground connections on intake manifold as instructed (cleanest thing on the car)
check load signal from the LH control unit- should be 0.1v between terminal 8 and ground (0.13v for my reading)
check power to amplifier and coil for battery voltage: 12.5v
check engine speed speed sensor signal to the control unit: check for resistance between terminal 10 and 20. THERE IS NO WIRE AT TERMINAL 10! Read about the possibility of a wire at terminal 23...
At this point I gave up and have referred the hive mind of volvo experts here.
I have lurked around but am unable to find an answer.
I have had many 240's but none with the LH 2.4 and problems like this.
What should my next step be?
Thanks in advance.
If I can get it working I will tell you the true story of Toronto mayor Rob Ford and his brother Doug having a low-speed, OJ style car chase with a Rob Ford impersonator who was driving this car.
Also, is there any Volvo groups or clubs in the Ottawa area?
