940 turbo won't start, lots of troubleshooting already done. I'm stumped.
I am having a problem with our '94 Volvo 940 turbo. It had no problems with it Friday, and it was running fine when my wife parked it at about 9:00 PM. Saturday morning, the battery was dead. Not completely flat, but only had about 6 volts. I couldn't even get the car to crank on the heavy duty charger. I left it to charge for about 3 hours, and it took no charge. She mentioned a couple days before that she smelled sulfur, which I attributed to a cat going bad. When I pulled the battery out, it had no water in it at all.
So, I put in a new battery, and now the car was cranking fine, but wouldn't start. IT wouldn't even sputter. Thinking it was possibly flooded, I pulled all the plugs which were totally soaked with gas. I cleaned the plugs & dried the cylinders by lighting a grill lighter by the plug holes (I know, bad idea, but I learned it from an old school mechanic & it was all I had the patience for at the time...). Still nothing.
I checked that it was getting spark by plugging a boot from each wire onto a plug and laying it across the intake manifold and cranking the engine. All were getting good spark. Still nothing.
I replaced the obviously worn cap & rotor, still the problem persists.
Our gas door broke off a while ago, and once my wife forgot the gas cap when it was raining, and we got a bunch of water down in the gas tank. I thought that maybe since these have a little area that tends to hold water that may have held enough water to seep in under the gas cap (we got a LOT of rain Friday...). So, I drained all the fuel and refilled the tank, still to no avail.
I have also checked the fuel pressure & all the temp sensors, all are fine.
So, after all this, I still can't get this thing running again. Any thoughts?
