Not sure on this one.....if it's "drive by wire" that means the accelerator pedal is connected to the intake electronically, and that may be where the A9 code comes from. Saturns are drive by wire and it's a common failure point for them. spark, compression and gas is all you need for the engine to run. you can put a fuel pressure gauge on the rail to determine fuel, assume that the compression is good, and pull a spark plug and ground it while cranking to see if gets a spark...

What code reader do I need to read a problem with the AWD on a 2000 GMC safari


The generic obd2 code reader is good for reading codes of faults relating only to faults affecting or potentially affecting exhaust gas emissions.

For driveline, braking and body faults an altogether more expensive and professional code reader or preferably a code reader/scanner (with bidirectional software if possible) and loaded with manufacturer dedicated software...

Software can be bought or obtained and loaded onto a standard laptop, though without an obd interface and connecting lead it is still useless. Proper licenced software is as expensive as some of the professional tools.

I suggest you spend a little while leafing through a professional tool catalogue...

1997 Isuzu rodeo v6 2wd 3.2l has no spark from the ignition coils. Ignition Relay changed. Crank sensor changed. What else could be wrong. The motor just turns over like it wants to start but doesn't.


have you checked for a broken timing belt /chain
what about faulty cam shaft position sensors
it would be a champion idea to run the fault codes before wasting money changing what is not faulty

check engine lights also refer to transmission problems , over heating

2000 lincoln town car eatc gone blank, does not blow air.


Could be a temperature sensor/resistor, a relay, a fuse, or the blower motor itself. Change the fuse and relay first, then the resistor, and finally the blower motor. In many vehicles, these are wired in series so if one fails, the system will not work. A Haynes manual for your vehicle is a sound investment. Wiring diagrams are in the back section and taking a careful look will see you figuring it out in about 45 minutes. Some vehicles have fault codes assigned for such faults and you need a fault code reader to extract them. Check the manual first to determine if there is a fault code associated with that function; otherwise, the code reader won't do you any good.

My 1999 BMW Z3 will crank & will not start.I used Bavarian code reader code A9 & code 44 show up.What do I need to replace?


an engine needs fuel, compression, and spark to go....check those things first. Put a fuel pressure gauge on the rail, then remove a plug and ground it to see if it sparks, lastly, run a compression check on it. make sure the cam is turning as well.

MOTOR CONTROL SYSTEM FAILURE Light has come on


First I suggest scanned the computer car in order to know what fault code is stored there; sometimes Autozone or AutoShop with OBD scanner reader tools make this job for free. Note the fault code number and send us for other details.

Light looks like a motor


That is the check engine light. Read on.

When the service engine soon light a yellow light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
