Question about 1979 Pontiac Firebird

Colors of wires on the starter

I have the main power cable and a purple to the (S) side on the starter. the car used to be a 4.6 ltr, but now running a small block 305. I believe there are 2 other wires joined together also SUPPOSED to be going to the positive post as well, giving the fuse box its power.. I have no power except at the battery. Need to find out what color wires give the fuse box power that would run off the starter.

They should be orange or black wires with a fusible link. They should be with or near the purple wire. They didn't get pinned between the block and the transmission?

Which wires go where on a 2003 3.4 liter Chevy

There are three posts on the starter solenoid. Two large ones, and one small one. One of the large ones has a braided wire going into the starter. leave this one alone. On the other large ones, you will connect the positive battery cable as well as the large red wire coming from the alternator. The small purple wire connects to the small post on the solenoid. Lastly, on the engine block pointing the opposite way (towards the drivers side) is another stud and you will connect the negative battery cable to it.
Make sure that none of the wires can touch the other posts coming out of the solenoid.

Starter wiring diagrams

Should be pretty obvious by the size of the terminals to the size of the connector on the wiring. The obvious is that the large cable(4 gauge or so) will go to the top large stud on the back of the starter solenoid. Any small wires (14 gauge or so) with large connectors will go under the 4 gauge cable and the one small wire (12 gauge) with small connector (I think it is purple in color) will go on the s terminal of the solenoid.

Hopes this helps.

2000 chev wont start at key

From the ignition switch there is a yellow wire that is for the starter. probe it when trying to start. If you have no voltage replace the switch. Also, I believe there is a fusible link in the wire by the starter. It will be a different color than purple. Probe on the back side of it to see if there is voltage at start up. If so, replace with the smae color link.

2000 chev wont start at key

I think the purple wire (or maybe the yellow) from the neutral safety switch goes to the coil side of the starter relay, turning it on so power is sent from there to the starter solenoid. You could check for this signal to the relay with a test light. The key must be held in start while you probe the other two terminals for the relay. If the signal is there, either a bad relay or the coil side of relay is not grounded properly. It is possible that the coil side ground is the neutral safety switch-grounding the relay's coil side only in park or neutral-in which case the nagging light on shifter (between off and run, it only works?) may be telling you the safety switch is the problem.

You may need to look at a wiring diagram, Greg. But the starter relay is the last component in the start circuit before the starter solenoid. From battery to ignition switch to "crank" fuse to neutral safety switch to starter relay to starter solenoid to starter-and back to battery through ground. That is the start circuit. Just that the wiring tying them all together makes it complicated.

Chevy Tahoe Intermittent No Crank

I will try to help, powell. Your start circuit from battery to ignition switch to starter-and back to battery. You may need to check every thing here, including the grounds, for a loose connection, or just possibly a failing part.
If only complaint is intermittent starter action, and no other problems with ignition switch, let's assume switch is good, so battery to ignition switch is good. Now from the switch, a yellow start wire goes to the instrument panel fuse block, to "crank" fuse #8 (10 amp), from there a purple wire goes to the safety switch. If manual it is a clutch pedal position switch (simple on/off switch-when clutch down switch is on). If automatic, purple wire goes to Transmission Range Switch on the transm.-in park or neutral the purple wire has continuity in and out of switch.
From that switch, the purple wire goes to the starter relay (under hood fuse-relay center). Now the relay: purple wire in start will energize the relay- wire goes to coil side of relay, and then coil side goes to ground. On relay power side, the power feed is a red wire-and it is the same red wire that initially sends power to the ignition switch. A 40 amp fuse in fuse-relay center sends power to ignition switch, and a splice goes to the starter relay as the power feed for relay. When relay is energized, contacts close, and power is sent from relay to the starter solenoid, again on a purple wire. When solenoid contacts close, starter motor is connected to the big battery cable on the starter.

There is your start circuit. try a new or different relay, try a new or test the clutch switch (or transm. range switch). Buy a $5 test light and use it to check where power is lost when starter won't operate. Hold key in start and check if fuse #8 is getting power. Check the safety switch, with key held in start, the purple wire should be hot. Check if relay has a power feed (pull relay out and check terminals) and if relay coil has a power signal in start. Check the relay's coil side ground. If that ground is intermittent, relay won't work.
When it won't start, use a test light, you should be able to find it.
Good luck.

Starter wiring

According to my wiring diagram, you should only have one small wire which is purple. That wire goes on the R or S terminal. The I terminal was used for cars with point system ignition before electronic ignition.
The purple wire should be hot when the key switch is in the start position.

I do not know how to put the wires on to a starter to a 1983 chevy Monte Carlo SS

The starter will connect like so;

Be sure that the "-" negative battery cable is dis-connected from the battery before you begin.

The "+" positive battery cable and all of the other wires with the large eyelet connectors will connect together at the large upper main or "BAT" terminal on the starter solenoid.

The "S" terminal on the starter solenoid is for the field wire from the ignition switch, and it will usually be a purple colored wire, however the wire could also be pink or brown and it will have the smaller eyelet connector.

The "I" terminal if the starter solenoid even has one will only be used if the vehicle is an early year and the distributor has a breaker point ignition, and it is not used for electronic distributors.

Here is a diagram to help assist you, and let me know if you require any further assistance.

We are replacing the starter solenoid on our 1994 Oldsmobile Cutlass Ciara. When putting the new one on the car acts like it wants to start. What do we do?

Hello! Check your wiring...If +12 volts is connected to the "S" lead the starter motor will run...Lets check the wiring...
The "M" lead connects the solenoid to the motor...The "B" lead is the main +12 volts from the battery (Black Cable)...And the "S" lead is the smaller gauge Purple wire which is controlled by the ignition switch...If the Purple wire is making contact with the Black Cable the starter will run...

I have an 87 ss monte and the previous oner had the whole msd 6al system on it and took it off befor i got it and now im left wondering why it has voltage to the alternater and starter but no power to...

Sounds as if the Alarm was Disconnected and the Original wires were NOT PROPERLY Spliced back together, and the Wires you speak of, I would NOT TRUST Unless you can Determine that they are ORIGINAL to the Vehicle, You Must Hunt DOWN ALL ORIGINAL WIRING FOR THE IGNITION. Purple, RED PINK, YELLOW, ORANGE, Are the COLORS for the IGNITION thesr are all the MAIN Wires that Supply POWER for ALL KEY ON Components, and the PURPLE is the START TRIGGER Wire to the STARTER. rejakwilson @aol.comfor IN DEPTH Info on this, and Please EXPLAIN what you DO Have, where they are located,ETC. Hope this Helps you.!!
