2002 s60 volvo starts and stalls whithin about 2 seconds,no messages,,dealer wants to replace ecm but will not guantee this will work although i have to pay,they already reprogramed and replaced other module total cost of parts so far 2300.oo

Volvo security systems will cut off power to the starter motor if triggered. Sounds more like you have a bad crankshaft sensor or camshaft sensor. They are what triggers the ECU to turn the coils on and off. Alarm is NOT your problem.

Lock / unlock your door with the key . Then try.

Vacuum leak is cause

Check and/or replace the gas gap and try again.

I had this problem on my 02 s60 after messing with the battery. The problem is that the computer is stupid and "forgets" how to manage the car if it completely loses power.

To retrain it you basically just drive the car. I've seen several sets of instructions but here's what works for me:

1. Start the car and let it idle until warmed up.
2. Using moderate throttle (don't floor it) get the car up to highway speeds.
3. Slow down to a complete stop.
4. Repeat 2-3 a few times if you're so inclined.
5. Done!

Skipping the highway part will work too, however, I've heard it can take much longer to retrain the computer (weeks to months depending on driving habits.)

It will not work. The speedometer cluster would have to have the software downloaded to it be a dealer.

not sure but i have a mercedes c180 and every time i take off the battery for whatever reason mine always stalls for about 50 to 100 miles as far as i can see it wipes the program on the cars ecu and afetr driving for a few miles it reprograms its self and rung great how long has it been doing this for and how many miles has it done since battery removed hope this helps ivan

you will have to have the SRS system reset at volvo dealer. should be around $85 for reset

you can only get it at the dealer because of the chip that is implanted in it,new key has to be programmed only by the dealer cost about 150.00

passenger side under car ,10mm socket ,remove bracket ,press in plastic retainer and pull filter or fuel line on both side,install new filter with arrow facing forward inside bracket, crank about 2 times and it should start
