1995 Volvo 850 Two Wheel Drive Automatic

The pastor of our church owns this car. He's had occasional hard starting after driving, whereby all the electronics work, but it can take up to 1/2 hour to get the car to start. It doesn't seem to require a battery boost, it just plain won't start until it cools down.

What's a good thing to start looking at for this model car? I'm not particularly familiar with the 1995 volvo 850 Turbo Station Wagon. Usually focus on GM/Fords.

WHEN YOU SAY THE ENGINE DOES NOT START, DOES THE ENGINE CRANK?

Nope, it just sits there. Doesn't even make the ruh-ruh-ruh sound. No starter spin either. You apparently have to wait 1/2 hour or so after you come out of the grocery store, for it to reset or something.

I did put together a vacuum hose that was found near the front of the car behind the right horn, that was not connected. It was a small line with a rotted rubber connector. No clue if that had anything to do with it, as I have yet to get the book on this vehicle. Since it's only in the first 30 days of purchase, the owner is considering returning the vehicle.

I KNOW THERE IS AN IGNITION CONTACT SWITCH INSIDE THE IGNITION SLOT. IT MAY BE MALFUNCTIONING. TRY TO WIGGLE THE KEY WHILE INSIDE IGNITION AND SEE WHAT HAPPENS. LET ME KNOW.

Will do.
When the problem occurs again, I will have him replicate your advise. If that is the case, then we have our answer.

The Key Jiggling thing didn't work.

However what apparently has worked twice so far, is to press on the Brake pedal.

Now I've had other issues where you can't shift out of park because of a bad sensor or broken wire to the Brake Switch, in several Ford models, but I've never heard of the brake pedal being pushed allowing a car to start.

WHEN THE ENGINE DOESNT START, SHIFT INTO NEUTRAL AND TRY RESTARTING. ALSO, IF THE ENGINE STILL DOESN'T START AFTER SHIFTING INTO NEUTRAL, SHIFT IT BACK AND FORTH BETWEEN PARK AND NEUTRAL; WHAT I HAVE SEEN IN SOME CASES IS, THE GEAR POSITION SENSOR MAY MALFUNCTION. IF THE SENSOR THINKS THE TRANSMISSION IS IN GEAR, THE ENGINE WILL NOT START. ITS SET UP TO ALLOW START UP IN EITHER PARK OR IN NEUTRAL.

I will pass that information along. We shall see if that is the case. I should really just throw it on the code reader and see what's what. Cause honestly if it's the Gear Position Sensor than chances are good it would throw a code out to the computer.
