Won't start

You are most welcome. Visit us often, and tell your friends.

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

You need to see what is missing when it wont start. Check fuel pressure first.

What kind of pump did you use?

Check the positive wires going to the starter and the one going to the fuse box. If it has that much short check around the interior fuses to see if any wires get warm or hot. Also the wire that goes to the starter, may have rubbed against the exhaust or other sharp metal and shorted out.

Hey Mike,

It sounds like the battery has gone bad, here is a test to check it out.

Please let us know what you find so it will help others.

Best, Ken

Try this.
30 MINUTE LEARN PROCEDURE

TOOLS REQUIRED
None

Turn ON the ignition, with the engine OFF.
Attempt to start the engine, then release the key to ON (vehicle will not start).
Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes (the vehicle is now ready to relearn the Passlock(tm) Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).
Start the engine (the vehicle has now learned the Passlock(tm) Sensor Data Code and/or password). IMPORTANT: The vehicle learns the Passlock(tm) Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
With a scan tool, clear any DTCs if needed (history DTCs will self clear after 100 ignition cycles).

I need you to check something. Have a helper turn the key to the start position while you check for power to the smaller wire on the starter. You should get 12+ volts. Let me know what you find.

If it cranks good but won't start, have a helper crank it while you check for spark at the plugs. If you spark everywhere, use a gage and check fuel pressure. Any applicable trouble codes? What is litre size of engine?

How about checking for spark at the plugs and fuel pressure?
