I Really Need Help I Have A .1989 Volvo Wagon 750 With Turbo

It Start And Run Good No Problem There

But When I Step On The Gas Pedal And The Turbo Engages The Engine Will Cut Out And Die And It Can Drive Around A Little Bit But When That Turbo Engage It Will Shut It Down

I'm Trying To Fix It For My Brother He Got A Baby On The Way And The Car Is In Really Good Shape No Dents Everything But That Issue With That Turbo

Thank For Any Help

 

did u ever fix this problem?

 

If the boost gets too high (maybe waste gate hose is broken) on some Volvos the fuel pump power is cut, making the car loose power - OR

Any air leak between the air mass meter and the throttle plate can cause a power loss, such as a hole in one of the inter-cooler hoses, on the exhaust side from the turbo to the inter-cooler, Air mass meter to turbo, and the 2 short ones at the top on the drivers side - all get holes in them - OR

Look in the air filter box - there's a foam pad that comes off and blocks the flow of air into the air mass meter (i imagine that's been gone a while though) - OR

The fuel pump is failing, under high boost/high fuel demand the fuel pump can't deliver enough fuel and the system goes very lean - OR

Many other possibilities -
