Re: Introduction Volvo 850T no spark no injector pulse

I was able to get my wifi obd2 to record the voltage drop while cranking. It looks like it’s going well below 10V

Re: Introduction Volvo 850T no spark no injector pulse

Thanks abscate,
What would be too low for voltage when cranking? With the old battery I was getting about 10.4V while cranking. I haven't had a chance to measure the new one yet.

Re: Introduction Volvo 850T no spark no injector pulse

New Battery, no luck. I do have one other clue, I had someone hook up a fancy scan tool to the obd2 port and was able to communicate with the ECU, but as soon as I turned the key to engage the starter, the scan tool would lose connection and get booted out every time the starter was enaged. I wonder...

Re: Introduction Volvo 850T no spark no injector pulse

I just had the battery checked out, and it is bad. It holds enough voltage to crank the engine a few times but then the battery dies and I need to charge it. Would a bad battery cause a no spark even though it still cranks strong? I don't to waste money on a battery if it won't help the problem.

Re: Introduction Volvo 850T no spark no injector pulse

Thanks for the replies. I’m curious about the immobilizer, would it still allow the engine to crank but no spark/pulse? Update, I found the intake cam was off one tooth (advanced). The PO replaced the timing belt before the engine install. Obviously I need to get the timing right but I can’t imagine...

Introduction Volvo 850T no spark no injector pulse

Hi All, I recently acquired a 1995 850 Turbo sedan. I think it's a pretty cool car and I would like to get her running. The guy I got it from had just put a good used engine with low miles in it. The problem is that there is no spark and no injector pulse. I have gone down the rabbit hole of the int...
