the starter still turns after I let off the key!! HELP????

My starter keeps sticking about 1 out of every 5 times I go to start my car the starter just keeps going so I have to shut my key off, then lift the hood and hit the solenoid and it stops now you would think it is the soleniod but I have put 6 diffrent ones on it even diffrent styles. I cant figure out what is making my starter stay on after I turn the key off still. ? Can someone help me out.? I even took the starter off it and took the nose cone off and every thing and cleaned the brushes and everything in there.

The solenoid would have been my first guess too. : Check all your grounds and cables. If your not making a solid connection it could cause the contacts in the solenoid to arc and basically weld together causing the starter to keep turning.

True. If you have a test light you can put it on the hot wire (the one that activates the solenoid when you turn the key) And have someone turn the key to the start position then to the off position. If the light stays on in the off position, the problem most likely lies in the ignition switch as Darrell suggested.

Mustang Still Running...

I have a 90 LX 5.0 with a few bolt ons...I just had this running after the key is turned off...I replaced the Ignition switch, which seemed to work for a couple of days...Then a friend said change the solenoid. The problem is back I can't put the Neg. cable to the battery without an ARC! Help!

If you got spark at the negative cable, it sounds like you have a hot wire rubbed thru on something. More than likely check your hot wire to your starter to see if it rubbed thru on a header or something.

What kind of ignition do you have? Plug heat range?

Plugs that are way to hot can cause a car to diesel after the ignition is shut off. Also ignitions with huge coils can sometimes pickup feedback and keep running after they are powered off. For the former, colder plugs would fix the problem, for the latter, a ballast resistor on the coil will solve the problem. Also you could have a faulty ignition switch.

If your timing is not set right, you could also produce enough heat in the combustion chamber to cause dieseling...

88 GT CHI headed 351w 10.8 @ 125 - still figuring it out.
03 Cobra 2.3 whipple 10.7 @ 129 - sold it
04 Mach 1 12.7 @ 109 mostly stock - sold it
89 LX procharged 302 515 hp 497 ftlbs 10.7 @130 mph - sold it

I believe you said you have a fairly new 347, so that would dismiss the idea behind carbon buildup on the pistons hopefully. It could be the wrong heat range plugs like Ryan said. It could be you are running rich or the timing or a combination. I think you said in another thread you had a heat problem which could contribute. Also, when engine work is done and sharp edges are left they tend to get hot and cause this problem, that would be a last guess though. Wow this didn't help at all huh?

Have you already tried running codes? The 02 sensors use information from other sensors such as coolant temp sensor to decide a/f mixture. Your fuel shuts off the second you turn the key off, so my guess has to be excess fuel burning off probably caused by heat from the plugs. By the way did you ever get the fuel thing from last time fixed? The one that happened more when wet.

I had a 5.0 F-150 that had that same problem. I started it and the starter just kept spinning.

The problem with mine turned out to be the starter relays, not the solenoid. They look like two square fuses that should be grouped together under the hood, maybe one brown and one green. Try checking those as well. They're not water proof and a little bit of moisture inside does alot of damage. Also, they're cheap to replace.

Gonna go out on a limb here and say that the solenoid is the relay on a mustang.

I believe in the F150 the solenoid is on the starter itself, requiring a separate relay. As where the Fox Body's solenoid is on the fender.

I think you're side stepping the issue. You need to find out why you're dieseling.
