Not starting

Good afternoon,

Do you have a volt meter or test light to do some tests at the starter relay?

I attached a diagram for you to view.

So I assume you have no power on the control wire but do have power on the 12 volt from the battery? If so then check the fuse, relay, and the range sensor to see if we have power coming from it.

Basically the PCM is in control of the starter so we need to find out where we are loosing voltage so we can see what the issue may be.

Basically we need to just test voltage at each of these locations when you are turning the stater to see where we have voltage. So follow it through from top to bottom on the wiring diagram to see where the voltage stops.

Let me know if you have questions and we can figure out how to answer them. Thanks

Thank you will try see what happens.We have 12 volts starter spins when jumped .We put in new starter switch.Hopefully this will work.Thank you again.

Did you check for voltage to the relay?

Roy

No. try tomorrow not near car .Just seems funny turned car off 8 hours later would not start. Thank you, will try.

Keep us updated.

Roy

Okay, will do. again thanks .Old cars easier to me .Newer with computers mess with me.

Haha. Very true. Let us know how you make out. Thanks

Have power to neutral safety switch power, to starter.Relay clicks under hood but no power on wire going to solenoid.

Check for power to pin 87 on the relay with the key in the on position.

Have power with key on, key off no power.

In fuse box second relay clicks when key turned on.

When key trend on no sound from fuel pump.

You need power to 85 with the key on. That comes from the park.neutral switch.

Roy

Fuse box is burned looking below relays in engine department..That is the ones on left side of of fuse box.These relays are yellow looking.

With key on 87 is bright on test light but dim on 30 if that helps.Pulling on straws now.

No power at all on 85 nor 86 key on or off.

Lights work dash lights work .Alarm light stays on at all times.

Okay, you said there was power through the park/neutral switch which means if there is no power to the pin 85 then you have a broken wire between the park/neutral switch and the relay.

Roy

No have power at neutral switch on one pin.

Really do not know what relay you are talking about.Seems l have 4 yellow relays and two black ones in fuse box under hood with same numbers on them.

Which pin? What is the color of the wire?

Roy

All wires are so greasy cannot tell .With key on one wire lights test light.Think it may be chip in key.She only has one key.Take to key shop see if they can let me know.No noise for fuel pump at all.Hate taking up your time.

It is no problem. That is why we are here.

You need to test for power to the switch with the key in the start position. That will be the input from the ignition switch. Then there also should be an output, usually the purple wire, that goes on down the line.

Roy

Thank you.The car is 30 miles from me. My iPad does not work too good out there.Have power to starter power in and out of 40 amp fuse.Power at 87 with key on power to neutral switch power to 15 amp fuse in and out.Have long diagram with starter relay in junction box with 85 86 no power.Now at a lost.

The power for the relay control side, 85, comes from the neutral switch.

Did you verify that power at the switch was in start position only?

Roy

No, just checked for power. will do tomorrow.

Okay, keep me updated.

Roy

Okay, let you know.Thanks again.

You are welcome.

Always glad to help.

Roy

Have 12 volts to battery 40 amp fuse good, hot to starter, hot to 87, in box in front of engine compartment.15 amp fuse under dash is good.Black yellow wire in neutral safety switch.Still no power to red white to start motor.

I need to know the voltages at the switch as I requested.

Roy

Around 90 volts between 85 and 86.

Impossible. You have a 12 volt battery.

We or you established there is no power to the control side of the relay from the switch. I want to confirm that there is power coming out of the switch. If there is no power, you have a switch issue. If you do have power, you have a wiring issue between the switch and the relay.

Roy

Must be wire problem.Thank you. told her to get rid of that Ford and buy Chevrolet. Thank you for all your time.

Sorry Roy that was ohms .

No problem at all.

You need to check voltage, not ohms.

Can you give me the reading in volts? You measure it with someone holding the key to the start position.

Roy

Sorry, not near car maybe get her to come out.My mistake. will try tomorrow. thanks

Okay, let me know.

Roy

No power to relay on 86 87 only have power to the 30 pin.
