When it won't start....will it crank over or does it do nothing?

unhook battery 15 min hook back on lower driver window put key on ignition just bump the engine and wait until security lit stop flashing turn key off do it again 3 times once lit goes off crank engine an should start if lit wont go away or flash while cranking you have a security issue at switch or bcm now need a scanner capable to look at the security data

check the starter gear, maybe it didnt actuate.

check fuel pressure should be 41-47 with key on engine off.Sounds like weak pump.

actually a pretty easy fix. The pass key computer lost its programming. Put the key in and leave it on with the security light flashing. Just turn off all your accessories and make sure battery is pretty good charge. Anyway after you leave the key on for ten minutes the security light will come on steady so turn key off and right back on and start car. If security light still starts blinking and car stalls then do it again. It will usually work the first time but can take a few times to get it right.

I am having the same problem. did you figure out what was wrong with yours. I have tested all of the wires in the harness under the dash, they r fine. I pulled off the starter and had it tested; O'rilies said it was fine. It is a 5 speed, and I can push start the car just fine any time. Like yours, some days my car starts, some days it doesn't. The days it starts, it runs fine with no problems starting or running. the problem is the days that it wont start.

Try a crank sensor. Next time it stops pour or spray water on it and see if it will start. If it does you will know what you need.

after job is done turn key on for ten minutes until security light stops flashing turn key off then start the car

in the dist. the is an ingnition module check that if it is bad it is cheaper to buy new dist. than replacing the module
