Customer Question
I have a volvo...

I have a volvo vnl with cummin motor

Mechanic's Assistant: What's the make/model/year of your truck? Engine type?

2007,, it doesnt want to start

Mechanic's Assistant: Are you fixing your truck yourself? What have you tried so far?

I changed all filters

Mechanic's Assistant: Anything else you want the truck mechanic to know before I connect you?

I put the computer to the truck but couldnt connect to truck computer

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Truck Mechanic I'm going to connect you with knows all the tricks and shortcuts.

the engine light is off
Technician: Daniel Wilson,
 replied 3 months ago
Thanks for the update. The engine light should come on at key on and then shortly after cycle off. If it is not coming on that means the ECM is not communicating or by Volvo's terminology it would be the ECU which is still the engine computer module. Check for any blown fuses between your battery box and the engine ECM for any inline fuse holders that may have bad fuses or corrosion or damage in the wiring. Also test all your fuses in the truck for power on both sides with a tester. If the computer does not have power or ground it will not start. Check for that and let me know the results. Please remember to take a moment to rate my answers as that is how the site credits my time helping on the site. Five-star ratings and bonuses are greatly appreciated.
