I replaced the ignition housing,key and tumbler.it progressively got harder to start and now it wont turn over at all. do relays gradually go out and what is my next step. the starter is good as i pulled it out and tested it.where is the relay on the fuse panel for the ignition/starter?

Re: no power to the solenoid on the starter
There is no relay for the starter motor.Disconnect the plug from a tumbler and just short the positive wire with starter motor one.If O.K. the problem is into ign.switch.If your VW have automatic gearbox-check parking switch on gear lever.

Hello; what happens when you turn the ignition key to the start position? Are you getting a clicking sound? If so, it is most likely the starter solenoid that has gone on the fritz. The starter solenoid is located on the passenger side fender well inside the engine compartment. Sometimes, lightly tapping the solenoid with the handle end of a screwdriver will jostle it to work- DO NOT HIT IT HARD...you'll break the housing. Try jumping out the solenoid with the long shaft of the screw driver by turning the ignition key to the run position (where all the dash lights turn on), then jump out the solenoid; if the engine starts to turn over, you've isolated the problem. Replace the solenoid with a genuine Ford replacement part; don't use third party ones that can be purchased cheaply at an auto parts store. They don't last very long since they CANNOT handle the high current flowing to the starter, Let me know how you made out with your repair project; best wishes. BTW, if it is helpful, snap a photo of the solenoid before removing any terminals from it in case you forgot which wire goes where.
The Starter motor can keep running because of a number of things. It receives its power from the large contacts (switch) in the starter solenoid. WHen engaged, this starter sol. allows high current 12 volts to run the starter motor.
A number of things can cause the starter solenoid to stay engaged:
A) stuck starter solenoid mechanicals. probably not the cause
B) more likely a defective start position on the ignition switch in the ignition switch
C) possibly a gummed up ignition key tumbler
I would start troubleshooting with a schematic. Make your own or purchase a service manual. IF you pull off the wire from the switch (in the center console) which actuates the starter solenoid, and the starter motor continues to run, then its not the switch or the key tumbler. its the solenoid.
Troubleshooting is the logical process of elimination.
The solenoid on a starter receives voltage when you turn your ignition switch to the start position that tells it to activate the starter. When you use the screwdriver to start the car, you are basically bypassing the solenoid on the starter. Since the car won't start when you turn the key, this means that either the solenoid is bad and the starter needs to be replaced, or the solenoid is not getting the voltage from your ignition switch that tells it to engage the starter. You might be able to eliminate the ignition switch as the problem if you get somebody to hold the key in the start position while you check to see if there is voltage at the starter solenoid. If you have voltage there, the starter solenoid is most likely bad, and the starter needs to be replaced.
Hi Rick, I'm glad to help! I see you've checked all the fuses. There's one more fuses I'd like you to check in the PDC under the hood. It's a 40 amp fuse that goes gets power from the battery through the fuse and directly to the ignition switch. If that fuse is good here's step 2: Swap the starter motor relay with the same kind in the PDC and see if it will start if it doesn't. Here's step 3: have someone hold the key all the way to the start position while checking the small wire at the start motor with a test light, if it lights up, tap the starter with something, a hammer to see if it turns over, if it does replace the starter. If the wire at the starter doesn't light up then its not seeing the ignition run circuit. This could be due to the nuetral safety switch or it could be that the ignition switch housing is broken inside or the tumbler itself on the end that turns the switch is broken. Here's a quick check, take the ignition switch back off and use a screw driver to turn it over by hand, if it starts then you know the problem is in the housing or the tumbler itself. Hope this helps and have an awesome day Rick!
Two parts to this circuit, the low current: power supply to the ignition switch which then passes to the small wire on the solenoid when you turn the key to the start position, at this point there should be an audible "click" from the solenoid. Don't forget the solenoid needs an earth to operate, so check the earth path too, usually through its attachment point(s) Check that the ignition switch has power going to it. Check that the power is transferred to the start wire when the key is turned. Check the power is arriving at the solenoid, small wire. Check the solenoid has a good earth. Does the solenoid "click" when you try to start? Yes to all this? Then the low current side is good. The high current side: a permanent live (hot) to one side of the solenoid. When the key is turned to the start position and so long as the solenoid "clicks" then the power to the permanently live terminal is transferred to the other high current terminal. If it is not, then the terminals inside the solenoid are burned/dirty/high resistance. You might be able to dismantle, else change the solenoid. If the power does transfer, but the starter motor does not turn, then suspect the starter motor itself. Check there is a good earth for the starter motor, the heavy duty cable to the engine is in good condition, terminals clean and tight etc. If all good, then the starter motor is most likely U/S.
You'll need to figure out if it is an electrical problem or something hanging up in the bell housing. You can leave off the wire from the key and try it to see if something is powering the solenoid after you release the key switch. If your model has the solenoid on the fender it could be sticking.
The starter solenoid is bad or the ignition switch is bad. Check the solenoid to see if it is getting power. If the solenoid is getting power then the solenoid is bad. But if the solenoid is not getting power with the key in the start position, then the ignition switch is bad.
clean your battery terminals and all grounds to the battery cables and check if the battery has 12 volts to 14 volts if not charge the battery then load test it. if the dash red lights go dim when you turn to start position your starter is bad or your battery is too low. You can have someone hold the key in the start position while you tap the corner of the starter housing and see if it turns over. The starter bushings are worn if it turns over.(needs starter replaced)If it does not go dim then the problem may be in the electrical switch for the ignition. The switched power to the starter solenoid comes directly from the ignition switch to the starter solenoid (purple) Test if you are getting power to the starter. If not then check from the ignition switch mounted to the steering column. Make sure you pay attention to which wire goes to which post if you remove it for a bench test. If you get them backwards it wont do anything. .If oil leaking on the starter you will want to fix the oil leak so it doesnt ruin the starter probably valve cover gaskets leaking oil.
