Question about 1998 Volvo S70
I have a 1998 Volvo S70. It starts fine when it is warm outside, however, when it drops below 40 degrees, the engine just won't seem to turn over. When the temperature is between 20 and 35, it usually takes two cranks. When it is from about 5 to 20 degrees I have to crank it numerous times until finally it turns over and once it is started it wants to shut off so I have to sit there for a couple minutes reving the engine till it's 'warmed up'. Then if it drops below 5 I can crank it all I wants until the battery finally dies out. This is the third winter now that it has done it. The first summer we had 'the computer updated'. Then last year we replaced the battery. This year, we replaced the ETC (I think that's what it is) and it at first seemed to help, but now it has gone back to the same old routine.
Also, I don't know if it is related, but when it is really warm or really cold, it seems to have problems accelerating. It will be going along just fine and then like 'pause' and then kick back in?
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!
