I am on here to help a friend out. He drives a saab 9-3 and has NO problems with it until recently he through the serpentine belt and the car stopped, of course. He replaced the belt and now it won't start. Is there a emergency fuel cut off or something.
The car will turn over fine but won't start. Any ideas what this is? He has been driving his 3rd car now for sometimes and the saab is just sitting. Help
thanks

THe belt has a bad tendency to take stuff out along with it...tell him to look arount for ripped wires/hoses

I looked for a minute but i guess we need to take another look

Roto

yeah you do....I bet the thing knocked something off...does the car crank? Do you hear the fuel pump priming? It could havedamaged the CPS wire.

I hear the fuel pump, not starting at all, just turns over with the starter

Ok, so the car is still down. We checked the fuel rail. We have gas to the fuel rail. We pulled out the coil pack banks one at a time, inserted the spark plugs in them, and angled the plugs ontop of the valve covers and turned over the engine. All 6 of the spark plugs spark when turning over. I poured fuel down into the cylinders and tried to start, it, still nothing.
We checked the timing belts, and both are there intact and moving with the motor. We also took a plug out and checked to make sure we didn't have catastrophic failure, the pistons are going up and down. We also chainged the oil to look for metal in the oil, nothing there.

So, we have fuel, we have spark, we have timing, and no outwardly signs of failures ANYWHERE.
The only other symptoms are that it seems to be turning over faster than before when it was working. The motor just seems to spin over free'er than before this trouble happened.

I have tried everything I can think of. Usually if you have fire, and fuel and air, you will start an engine.



OH, while troubleshooting I found it is a 99' 9-5 TURBO V6 Saab. You help is MUCH appreciated! Please responds as soon as you can.

Roto

can you run a compression test?

jwrape

Not at the moment but I will get the tool and check it. I am thinking somthing is up with the vavles or something because it is spinning over faster than it used to.

Roto

are you sure you put the new belt on tight? If the tensioneer isn't up to par it will spin faster.

jwrape

I think we have a bent valve issue. All signs poin to that but the timing belts are both on and do not seems to have any distortion. But my thought is that he was accellerating hard when the accessory belt let go and maybe the extra momentum made the timing jump time.
What do you guys think?
