1. It sounds like you may have a Flat Battery
2. Dead Crankshaft Sensor
3. Blown Starter Fuse or Relay
4. Dead Immobiliser
5. Factory ground cable???
Using a test light, clip check for ground at coil (-). If ground is present with the key in the "on" position but goes away when cranking, it is most likely that the anti-theft system (imobilzer) is taking ground away from the coil to prevent the car from being started. If this is the case, go to the alarm module (below the dash to the left of the steering wheel) and locate the large connector for it (leave it plugged in). If you jump wire the upper and lower far right wires, the car should start. If the car now starts, you have a fault in the anti-theft circuit.
(Factory Ground Cable)
I had my 1982 BMW 320i for 17 years and the last few years intermittently I would turn the key and nothing at all , Just would not start,. It could be the very first thing in the morning or after coming out of an hours shopping at the market. Wouldn't make any sound at all when I would try to start it. And of course It would never happen when it sat at the mechanics. I was so fed up I had some time and drove to my long time friends shop, and low and be hold with gods help I'm sure...It happened! After testing a few things under the hood he asked me to step out of my car and raised it on the rack, he walked under the rear wheel and said yep here's the problem...The Factory Ground Cable was lose and full of dirt and grease and was not grounding. He cleaned all the dirt and grime off and tightened the bolt and it never happened again. Mystery solved.
Possible crank/cam sensor problem
check spark check spark
Since no spark, start with the coil!
maybe an ECU problem
is the Battery any good? If it is then you might have a wireing problem
check your battery connections (maybe loose wires)
Either you have no fuel or no spark. Once you determine which you are missing, you will know where to look for the problem.
get a new spark plug
Will it turn over? if yes then check for spark and fuel
Check for fuel and spark
has it goty spark
scanners work for 96 vechicles or newer
Depends on the motor, 4cyl or V6, but it could be the ignition module, or the crank sensor
You could have a fuel pressure problem, lack of spark, malfunctioning computer, or internal engine damage.
If it has spark & fuel and will not start then the timing may be off.
Assuming there is not a major internal problem you need fuel, spark and air to get an engine started. So, from what you described I'd be looking at a problem with getting spark, probably from the ignition coil.
Purchase a spark plug spark checker at your local auto parts store, unplug each plug and check for fire to the plug while turning over.
Could be broken timing belt. Do the spark plugs have spark?
appears no fire going to spark plugs
its need 3 things to start fuel spark compression and they have to be all at the right time
I do not have a answer for it, do you an answer for this problem?
Have you checked for fuel and spark? Fuel pumps ad burnt ignition rotors are very commen on these vehicles
Fuel pump is bad!
You are missing fuel or spark.
