Are the plugs actually sparking? Do you have fuel to fuel rail? If so, are the injectors pulsing? Are there any codes in the ECM? Have you scanned them? To you have power to the fuel pump? There is really no way to answer your question over the internet.

Tricky ... Was the alternator replaced with a 2nd hand one or a new one?
A defective alternator can allow the battery to discharge within a few minutes (the diodes in the rear of the alternator can burn out and cause the problem. The diode pack can be replaced). When this happens recharging the battery only replaces the power in the battery - which drains straight back to earth via the alternator, flattening the battery again - often within a couple of minutes or less.
Does the battery lose its charge when the car is standing or just when the engine is fired up?
If the battery loses its charge overnight, try disconnecting the wiring from the rear of the alternator (also look at the electrical connector that fits into the back of the alternator - look for melting/burning marks which suggest something may be amiss inside the alternator).
Let the car stand overnight with the alternator wires disconnected. Will it start up ok and drive (with the alternator wires still disconnected) the next morning?
You could also try just disconnecting the alternator wires, firing up the car and then driving it -
If the car drives ok without dying out and gets further down the street than it usually does, then it probably is the alternator at fault. The car should drive until the battery drains and has insufficient power to trigger the ignition. You certainly would get further down the street with a charged battery and disconnected alternator than you currently do.
It does sound as though you've had an alternator fault to begin with. If it has been replaced with a 2nd hand unit that unit may also be faulty. Rather than replace parts in desperation, visit an auto electrician's - within a few minutes they will be able to test the battery/alternator output and also identify where the lost current is going. It will be cheaper in the long run to have an auto electrician look at the charging system. It only takes a few minutes.

You are in the Ballpark. It will cost you several Hundred to fix. Will prob have to have the module replaced. Go to a trusted European repair placed. DO NOT TAKE TO DEALERunless you want to give them the car. They are very happy with $$$$$$$$ You can fix for alot less than dealer. Good luck.

If you have SRS and "brake failure" it should be taken to a dealer. a shadetree mechanic will screw more up than he will fix in this case. trust me on this! you will pay a price, but will save you more $ and less headache in the longrun.
SOURCE: 1998 Volvo V70 with potential transmission problems?
Yes, it's the 'pnp' switch (also known as the inhibitor switch) which is on the side of the transmission.
I own 2 Volvo 960s (3 litre automatics) which are similar in many respects ... and have that flashing arrow. It's a well known fault and you don't have much to worry about.
Rather than write it all here, you can read what I wrote as an ebay guide about it at http://reviews.ebay.co.uk/Volvo-960-Automatic_W0QQugidZ10000000003233806
I did put similar info on my website at http://www.glennsmart.btinternet.co.uk/volvo960.html with photos
Though the ebay guide is better ...
If you haven't got time to read it ... forget the flashing arrow and put a bit of black tape over it ... My wife's car has (192,000 miles) had that arrow flashing for 3 years. My car (100,000 miles) has had that flashing arrow since I bought it 1 year ago.
I did change the pnp on both cars ... but you also need to have the computer error reset by Volvo to have the light extinguished. Don't worry ... keep driving.
SOURCE: ENGINE MISFIRE AND SHAKING
check your wire harness on the top of the engine. Volvo must have bought harnesses from Mercedes. The insulation just cracks and disintegrates, then the wires short. Not good for an ignition system.Once they short It can fry the circuit for that cylinder in the computer. Does not set a code other than Misfire.
