I had my spark plugs changed today and now my car won't start it will turn over but won't start

Check your PCM fuse

change the ignition pick up coil assembly normally located on the distributor under the rotor on the bottom of the distributor or just replace the distributor

pick up coil or module ?

Recheck the plug wires and ensure they are going to the correct plug.

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.

The next time it won't start ,pull a sparkplug wire and see if you're getting fire.Then we'll known whether its a ignition or fuel problem and go from there.

Are the plugs wet with fuel?
Check for spark. No spark? it may be the ignition module.

Plugs dry and spark present? No fuel?Spray a little starting fluid and see if it will run on that.
Then check pump fuses and for fuel pump noise.

Hi Paul brad hear, if you have spark plugs working i.e. sparking and fuel coming into the engine something has got to happen, many not start but it would backfire cough because when those two things come together something always happens. OK The other thing that would keep it from starting, the timing change or gear has broken and the cam is not turning. Im not sure if the Tacoma has a chance or gears. good luck

Have you tried the reset method? Turn key to the ON position and leave it there for 10 minutes, or until the security light goes off. Then turn key to off, and back to on and start-see if it starts after letting it sit for a few minutes like that with the key in the on position.

Did you mix up the wires? That will keep it from starting
