Hello,
I'm turning to the pros here for help.

Here's the deal.
I have a well maintained 1990 Volo 740 GL - Only 80,000 miles on her.

Three weeks ago (cold day <10 degrees) I went out and started my car and moved it ten feet and shut it off. I started absolutely fine.
A Half hour later, I went to start it again and it was cranking fine and acting like it was going to catch but never did. I also immediately smelled gas. Figuring the car was flooded. I held the gas pedal to the floor and continued to try to start it to no avail.

Had it towed to a local shop and they said it was simply flooded and they changed the oil, cleaned the plugs and said it started fine.
I picked it up and took it home. The next morning (very cold again) It wouldn't start...again, immediately smelled gas...try to clear it by holding down the gas pedal and again...no start. (cost with tow - $180)

Had it towed again to another local shop...this guy also changed the oil cleaned the plugs and he disconnected the cold start injector thinking that it was spraying in too much fuel. Figuring it was a cold start flooding problem. (cost with tow - $260)

I picked it up the next morning and it started fine and ran great as it always has.

Fast forward 3 weeks and I went out again on a cold morning. Started the car up just fine...moved it about 10 feet and shut it off and went out a half hour later to start it and SAME THING - Immediate smell of gas and NO Start.

This time I had it towed all the way to a Volvo Dealer who started that the connection to the Radio Suppresion Relay was bad and had to be rewired. So at the cost of $485...I had that done. The Service Advisor said that this should totally take car of the problem.
I picked up the car and it started right up. Drove it to the store a block away...ran in for just a second...came out and it wouldn't start!
I again...immediatelt smelled gas. I held the gas pedal down and luckily it did catch and fire right up...Drove perfect...no smoke...no loss of power. Nice Purring sound.
Drove it around for about ten miles and took it back to the dealership to have them look it over and they were closed.
I had shut the car off...I went to start it and it fired right up.

So...it seems that for some reason that if the car is ran for just a very short time and then shut off and tried to restart...
it immediately floods itself.

Does anyone have ANY IDEA why that might be happening? - I've got close to $1,000 spent on repairs and no closer to fixing the problem.
Any help is greatly appreciated!
