2002 Durango won't start change fuel pump, cramnkshaft sensor,


"No Bus" means something happened between the body computer and the engine computer. They are not connected to each other.
Usually a fuse, one of the computers, or the wiring harness in between.

Truck stalled wouldn't start.


I can understand you being frustrated.
There really is no way to tell if the fuel pump was the problem at this point.
If the security system fails, you should see "security" light up on the cluster.
The key lock has a sensor that reads the chip in the key. If the sensor fails or the chip fails the computer won't let the vehicle start.
Most of the time when the security system is at fault, the vehicle won't start, but it won't cause the engine to stall.
You might want to have someone check the fuel pressure and spark at the plugs if you don't see the security light on the cluster.
Could be the fuel pump relay and a list of other things.
I would probably check the computer for trouble codes too.

97 gmc jimmy cranks but won't start, have replaced everything possible but still won't start, most of the time the brake lights won't work, or the gauges goes crazy. I have changed relays,...


There are two basic reasons for not starting - no spark or no fuel, both of which are controlled by the ECM. You need to check error codes and these items - for the spark, test it at the cylinder 1 sparkplug; for the fuel check the pressure (if too high or low, problem!).

2002 saturn sl won't start, turn over but won't start


Done cars have a kill switch if they are low on oil. Check your oil. If the oil is good, it may be the ignition switch.

I have a 2001 Olds Intrigue that won't start every once in a while. When it won't start the security light flashes so GM told me it was the passcode and I would have to change the ignition switch...


you can not bypass the security in that car, it is built into the main computer, they have problems with the ignition switch screwing up and the only way to start it while the light flashes is to turn the key to ON but don't crank engine, leave on for 10 to 15 minutes until light goes out then start car.
