CAR SOMETIMES WONT START

By drive belt do you mean the accessory drive belt ? Or are you referring to the timing belt ? A broken accy belt should not cause the car to not start unless the belt slapped around and broke something in the engine area. Check all around and under the front of the engine for damaged wires or wire connections to engine sensors that may have been damaged by the slapping belt. If its the timing belt your talking about then you need a mechanic .

The top tips for making your car more fuel efficient are Set your cruise control to 55 mph, change your air filter, check for proper tire pressure, and don't allow your car to idle for long periods of time.

GM Tech2 GM Diagnostic Scanner

you have to check you engine starter (dispositive that is made to turn on your car)

if the fuse is good i could be the switch itself take out one of the switch and check wires with volt meter

I am a volvo tech and your problem is fuel pressure ralated and i had same problem in 1995 850 turbo and the fuel pump was the problem and a used one is around 35.00

1st thing, check the relays, behind the ashtray, give 'em a gentle twist, while turning the engine.
Bon chance.

Had you had the car scanned? It could be something else? Fuel pump, relay, fuse...
Is there any spark at the plugs? Is there fuel coming to the injectors?
There are a few things that can cause a car not to start, Is the engine light on?
Best way is to get the car scannd, if not you'll end up replacing unneccesary parts by trial and error.
Cheers

no, its on the bottom, big 1" brass plug very bottom of engine, easiest to get to from the front, I own the same car....

Sounds as if you have set the immobiliser, does your car have the volvo guard alarm system fitted, (is the red light on the window frame?) I found that when reconnecting the battery if you just tap the connector on the terminal 4-5 times before connecting it it would reset the immobiliser and the car will start
