    What year, make and model vehicle? Same as above? Do you know what happens when you turn the key to the start position or push the start button, which ever your vehicle has. There are complex electronics involved here. Plus, whatever fixed the other persons vehicle probably it's what's wrong with yours.

    Circuit Description
    When the ignition switch is turned to the Start position, the body control module (BCM) receives battery voltage on the ignition 1 voltage circuit, and less than 5 volts on the off/run/crank voltage circuit. The BCM supplies voltage to energize the RUN/CRANK Relay 32. The BCM sends a high speed GMLAN serial data message to the engine control module (ECM) that the key is in the start position. The ECM receives the message from the BCM, and also receives a serial data message from the transmission control module (TCM) containing the shift lever position. If the shift lever is in Park or Neutral when ignition switch is turned to Start, the ECM supplies voltage to the START Relay 31. The START relay supplies voltage to the S terminal of the starter solenoid, through the 30 A STRTR Fuse 26, in order to crank the engine.

    Do you know what high speed GMLAN serial data messaging is?

    A High Speed GMLAN Bus is used where data needs to be exchanged at a high enough rate to minimize the delay between the occurrence of a change in sensor value and the reception of this information by a control device using the information to adjust vehicle system performance. The High Speed GMLAN serial data network consists of two twisted wires.

    When you turn the key to on position (not start) does the check engine light turn on? The engine computer after getting message from the BCM energizes the starter relay to crank the engine, if the engine computer isn't communicating that won't happen. Try putting the gear selector in neutral an see if it cranks then .

07 malibu wont start, not turning over

Check your battery terminals and battery.
If the terminals are corroded or loose then this will happen.
If need be, remove the terminals from the battery and clean thoroughly both terminals and terminal clamps. Fit them back on and tighten.
Try starting the car, if it starts and all is good, spread vasoline, or some grease over the terminals to prevent it from corroding. If it doesn’t start then the battery will need replacing. If you have a multi meter check the voltage first. Anything under 11.5 volts will not start this car.

99 GMC SANOMA NO CRANK POWER TO THE STARTER IS GOOD. TURN ON KEY NO HEADLIGHTS ONLY PARK. TURN KEY NO POWER TO PURPLE WIRE ON THE SOLENOID.

Do you know what a wiring diagram is ? How to use a DMM - digital multi-meter to diagnose automotive electrical circuit's ? Looking at a wiring diagram to see what all is involved in the starter circuit , main battery cables , park neutral safety switch , starter relay etc.. Find video's on youtube . Do you have a manual or automatic trans. ? The purple wire get's B+ voltage from the starter relay in the underhood fuse / relay box .

We put the new starter on today, and the car still won't start. We are thinking it's the starter relay. What else can be wrong with the car? can you please help us we depend on that car. Thank you

There is no starter relay shown in a wiring diagram. The only thing between the ignition switch and the starter solenoid is the park/neutral switch (or the clutch pedal position switch on manuals).

Do the warning lights and gauges come on with key on? That would verify power is into the switch and being sent out. The small purple wire on the starter solenoid should have power on it when the key is held in start position. If it does, recheck your starter and battery connections. When the purple wire energizes the solenoid, the starter motor should crank the engine.
If no power on the purple wire in start, check the neutral safety switch or the clutch switch if a manual. The start wire out of the ignition switch is a yellow wire, and the wire from either safety switch to the starter solenoid is a purple wire.
(The power to the ignition switch is from the 50 amp Ignition fuse in the under hood fuse block.) See? The positive battery cable is connected to the starter, but not to the starter motor. When the key is in start, the hot purple wire energizes the solenoid and the battery cable is connected to the starter motor.

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.

My 99 Gmc jimmy will not start. the fuel pump is good the fuel filter is not clogged, i replaced the neutral safety switch, plugged in my code reader no codes, i believe it is the starter or the ignition...

Does it crank or not? If no crank then look at the starter or ignition switch. If crank but no start then look at the ignition system. Check for spark at the plugs and also check the fuel pressure. If there is spark try spraying a little starting fluid into the intake. See if it starts and stays running. If it stays running reply back and I will explain why.

My car just clicks when i try to start it new batt & alt

The starter solenoid may be faulty. The following procedure explains how to inspect and test the solenoid.

  1. Raise and support the vehicle.
  2. Inspect the starter and solenoid for corrosion or looses connections.
  3. Lower the vehicle.
  4. Remove the starter relay from the PDC. Connect a remote starter switch or a jumper wire between the battery positive post and terminals 87 of the starter relay connector.
  5. If the engine cranks, the starter and solenoid are OK.
  6. If the engine does not crank, or the solenoid chatters, check the wiring and connectors from the relay to the solenoid for loose or corroded connections. Particularly the starter terminals.
  7. Repeat the test. If the engine still fails to crank properly, trouble is within the starter or solenoid.

94 z wont start

You will have to check, at the starter, for power to the SMALL wire on the starter solenoid (which is on the starter) when turning the ignition switch to start.
If there is power to this wire ( usually purple ) and power at the LARGE cable ( from the battery ) at the starter end.....you need a starter.

If you do not have power at the small wire at the solenoid with the key in start position and battery power is OK.....check the safety neutral switch.Moving the shifter around a little can sometimes allow the car to start if the neutral switch is worn.

A new battery does not always mean a fully charged battery.
Try a boost from another car before testing the starter for power.

The battery cables need to be clean and tight....and check the ground to the engine as well.

Everything else may work OK with bad connections,they don't use the power the starter needs to turn the engine over.
