1988 MX-6 GT once in a while won't start, wiggle batt. cables then start, but not always solution. What are the problems? My current nickname is Mr. Puzzled. Thanx.

Try wiggling the key when it's running.(By your descripiton,it sounds like the igntion switch is possibly worn out.)

Pump or injectors may be bad .

I have a same problem. need help

Ok, if the cranking amps is like 70AMPs or 100 AMPS as measured by an inductive ammeter on the battery cable when starting, and it does NOT start, then it's a bad starter.

However, if it does start, that's normal.

On a car that old, I would check that the battery cable ends are squeaky clean, wire brushed, or even replaced if cleaning is not possible.

Usually, a battery that is tested good will be good under a load test.

Also, try to use an ammeter to find out if there is a drain on the battery above .2 A while it sits there turned off. This could lead to a solution if you investigate where a short may be.

Check the air intake tube that goes to the throttle body, Check for cracks or leaks, This can cause unmetered air to get by the mass air flow sensor

Cejck the primary and secondary resistance of your coil - you may also want to check the voltage drop of your battery when your starter soleniod is engaged as well. If the tarter soleniod is starting to go it will pull too much current.

you got a loose connection there...have the terminals cleaned and tightened properly. Watch out for a short circuits...be careful with the positive terminal as not to touch the negative or the vehicle chassis.

ok,first off make sure your battery isnt dead,,,if thats ok then id suspect the starter motor,,does it sound like a clicking noise when you start,,its either one or the other anyway,,,if it starts off the key when you use jumper cables then you need a new batt,,hope that helps

sounds like tou eather hurt the flywheel or your head gasket blew

inspect cables, they break down over time, corrode and turn green inside
