I installed a 960 engine from a 1993 volvo into my 1995 960 volvo, I used the wireing horness that was already installed in the 1995 volvo since the connection on the 1993 engine was different. I have yet to be able to get the 1993 engine to start.I seem not to get any fire at my ignition coils. I've checked my cam position and crank shaft sensors as well made all ground wires are properly connected. What else might I look for to resolve this problem
what would cause no fire to ignition coils other than improper grounding on 1995 Volvo 960

There is a ground wire by the left motor mount, this can be quite hard to tighten, and if it is loose t won't start. Also, check the ECT sensor, they often fail and cause a no-start problem. Are you getting and fault codes?

I may be able to help you and it can be very simple. My 1993 960 had starting problems, that is, the starter worked but no ignition and probably the fuel pump didn't work either. The ESW transmission light flashed so I thought I had the PHP? switch problem that is mentioned on the Web. But sometimes it fired off as if nothing was wrong. Two Volvo dealers had no idea. I checked the usual like the groung wire connected to the left (driver side) motor mount. While checking from above I moved a black cable and I heard a whinning noise that is the injectors or something (the start key was on.) The noise is normal because I jumped into the car and it started! I followed the cable and it connects to a relay. The connection was loose, that is, the connection is under the relay and gravity pulled against the connection. Let me describe where the relay is located. Stand in front of the car with the hood up. On the drivers side lean over and touch the black terminal box that sits on the side of the wheel well. Just to the right (as you stand) are two gray relays. They are just in front of the shock/strut tower. Make sure the connections are not loose. Also remember that 75% of all faults you can see or hear. William.
