Upgrade fuel system more fuel on the fire!

Could I have more information please. What year is this MX6? What size engine is it? Are the plug leads still in place on the vehicle?
There were 2 different V6 engines Mazda used and the firing orders were not always the same so engine size will help.
The plug leads are deliberately different lengths for a few reasons. When connected to the coil in the correct firing order the length will only allow the lead to go to certain spark plugs to help get the correct firing order, shorter leads look tidy on the engine and shorter leads cost less money to make for the manufacturer.

Scroll down to the MX6 and if yours is different, then you could have a non standard ignition or it was installed improperly but adapted and runs fine, or simply wrong and not likely to run.

What is your history with this engine?

Was it running prior?

Does your distributor cap have a flat top?

Is it a Mazda/Ford ignition?

Try a squirt of starting fluid into the air intake before starting. If it then starts and runs for a few moments then can give you a good indication that fuel supply to the engine has been lost. After that is just a matter of determining if the tank is empty. Pump not working. Or injectors not supplying fuel to the combustion process. If still no start with the starting fluid then need to check and see if you have ignition spark to the plugs.

On my 93 mx6 the spark plug wire that is all to it's self in number 6 and it is on lower part of the distributor, like a clock it would be at 7 on the face of clock and the distributor as you are looking at it,I know as I was looking at mine 2 hours ago.

Without knowing the name of the part you could look at the different connector and match one up. Good luck!

If you have spark and fuel (either via the injectors or spraying fluid into the intake), and still no evidence of firing, it suggests your valvetrain may not be working. If the valves can't open, the fuel cant get into the cylinder.

Do (or have done) a compression test. You may have a broken timing belt/chain.

electric pump

the tps may affect the idle, but not really the excessive fuel. check that your coil has enough spark, remove plug watch spark. otherwise check haul senders in distributor or check injectors are not leaking.
