Volvo 740, Electrical, Wagon

I have a 1991 volvo 740. I have owned it for 3 years and it has run great until now. Its not starting. I have had this problem for a while and would happen about once every six months but after 10 minutes or so it would start, but now its not starting at all. I have changed the spark plugs and wires, replaced the fuel pump. about a month ago its been doin it a lot lately but have got it to start using starting fluid but now it just wont start. Once it does start it stays running and doesnt die or have any problems. Any ideas? I have done a little research and could it possibly be the crankshaft position sensor? if so where is that located?

I went thru all that too. Ended up that the problem was the little spot right where the injectors spark. Got that cleaned and it's been fine ever since.

Hello, I'm having the same sort of issues with my 1990 740GLE wagon. I have just had both fuel pumps replaced but still seem to be having the same issue. Did you ever get a response or find a resolution to this issue? I'd appreciate any help you can give me!
#34 of 34 1990 740GLE wagon stalling.

I'm hoping someone out there might be able to offer some help. I have a 1990 740 GLE wagon which I bought with about 91K miles on it a few years ago. It has intermittently had acceleration issues which have now worsened. I noticed that when I let the gas tank run down to about 1/4 I could hear the fuel pump under the drivers seat working erratically. As I result I always tried to keep the tank at least half full.
While driving to get gas one night at about 30-40 MPH the car suddenly had no power...someone else in a post here stated the same problem by saying it was as if the accelerator had been suddenly disconnected. I rolled to the side of the road when it finally stalled. However, it immediately started up again and I was able to get to the gas station, fill up, and get home without further problem.
This same thing has now happened a few times even with a 3/4 to full tank. My mechanic replaced both fuel pumps but I am still having the problem.
The car will also sometimes not start. Usually when I turn the key to "on" I can hear the fuel pump activate. However, I have noticed that on the occasions that it doesn't start, I cannot hear the pump come on. I turn the key on and off a few times until I hear the pump activate and then it turns over just fine.
So, my question is, what might it be that is not telling the fuel pump to come on when the car is started and could this same thing also be telling the pump to quit while the car is moving?
I would greatly appreciate any guidance that anyone might be able to give to me!
