That battery may well be damaged beyond repair by bouncing around. The 1999- cars need a solid good battery or they wont run well. Test the fuel delivery system by measuring fuel pressure at the rail - you can 'rent and return' a fuel pressure gauge at Autozone or the like. A pencil type tire pressu...

+1 with Abscate on this. Check battery not only gives 12.6+V but also that the cranking amps are good. I have had batteries that show a good charge but have a bad cell that does not deliver the current needed. The battery is held in by a simple plastic clip when the correct type with the lower exten...

I think that you need a good scanner or vida dice and some time to work through those issues. Question if the spike in current or disconnected terminal created short circuit somewhere in electronic system. Incorporating some advice from above: 1. Move car to the area where you can work on it. 2. Rem...

Another possibility: I think volvo still offers free towing for up to 25 miles to the dealer. In case that helps with bottom line and you want dealer to look at it. In my neck of the woods people sometimes posted on craigslist asking for help with vida dice and I always was a willing person to help ...

13.8-14.2V with the engine not running? That is what I hope for with no load with engine running. 12.6V should be fine for starting assuming the battery does not have a bad cell. I would expect the pump to prime if it has been standing for some time. It only runs for a short time as it prime the pre...

I disagree on the testing method and also on the fact that current battery is not enough and you need to to buy a new one asap. First of all testing with multimeter will not give you true information if wires are able to carry current. You need to test it with 5amp test light. Take old headlight bul...

I think you might be right about that voltage Neil. I'll have to check mine when I go out today and see if that voltage is when I start the car or just before.

13.8-14.2v is at idle when engine is running.
12.6-12.7v is 100% charged battery,on rest,at least 2 hours after engine is turned off.

Use high quality fuel hose rated for fuel injection. Check pressure rating on the side should be at least 5-6bar. Avoid using worm gear style clamps and rather use specific for fuel system. You can always buy proparts unit from fcp or amd from ipd and if failed remove the assembly(you are a pro at t...

The AWD drive fuel pump design relies on a pressure fit between the pump and receiving nozzle on the pump housing. I didn’t feel good about it, but my new pump held and now has 25k on it. I did add a zip tie on the mount to help keep it together.
