My 98 volvo s70 won't start right away when it's colder than 50 degrees outside. It takes a few tries and I have to wait a couple of minutes between tries.

Check to make sure the car is in time. I have found with my 98 Volvo V70 that if the timing is off just a couple of teeth the car will crank but not come to a full start.
I am working on this RIGHT NOW. Remove panel (see Utube) remove white cover (Torx 25) from interior of exterior handle. You will see that lifting the handle pushes a rod down The rod is attached to the bottom half of the mechanism via a cheapo plastic connection, that can work loose. It is like a screw shaft (top) that squeezes (sideways) into a blue plastic channel which merely pinches the "screw shaft" to hold it. The connection has come loose. Squeeze upper shaft into (lower) blue channel. Added tiny bit of epoxy to bond "screw shaft" onto blue plastic gripper. Done. Saved $500.
Turn off the car and turn it back on, then check for any alarm buttons. Press those a few times, and try it. Also try to manually unlock the doors with the key.
YOU REPLACED BATTERY.BUT CHECK TO MAKE SURE YOU HAVE RIGHT COLD CRANKING AMPS.AND CHECK BATTERY CABLES.MAKE SURE THEY ARE CLEAN AND TIGHT.IF BATTERY CABLES OVER 10 YEARS OLD REPLACE THEM.MAKE SURE YOU ARE USING RIGHT VISCOSITY MOTOR OIL.YOU SHOULD BE USING 5W - 30 ENGINE OIL IN COLDER CLIMATES.IF YOUR OIL TOO THICK IT WILL CAUSE ENGINE DRAG WHEN CRANKING IN COLD WEATHER.
There have been a lot of problems with the compressor cutting out when it gets hot. When the A/C begins to blow warm, check the power supply wire to the compressor. If there is power in the wire, you will most likely have to replace the compressor. If there is no power, you will have to trace it back to see what the problem is (a wiring diagram will help greatly).
Look in the manual for the code - usually someone has written it in there. If not, call the nearest Volvo dealership and give them the VIN - they can tell you what your code is. Then, with the engine off, turn the key to the "I" position (Roman numeral one) and leave it for at least 4 hours. The radio should then read "Code. and you can enter the 4 digit number! Good Luck!
Check the B+ cable. If you remove the fuse box cover in the engine compartment (on the drivers side), and you'll see a post with a nut on it, securing a group of red wires. The connector should be a clean copper color. If you take it to a shop, have them perform a voltage drop test on the cable. If it is corroded or burnt, replace that cable!
