2005 caillac de ville starter clic- no start then saddenly starts and start every time.in 2-3 hours no start battery ok, continue clicking -start again ,we chenge 2 starters and battery

WARNING: CHECK TO ENSURE THAT THE TRANSMISSION IS IN THE PARK/NEUTRAL POSITION WITH THE PARKING BRAKE APPLIED.

RELAY TEST
The starter relay is located in the Power Distribution Center (PDC) in the engine compartment. Refer to the PDC label for relay identification and location.

Remove the starter relay from the PDC as described to perform the following tests:

1. A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go to Step 2. If not OK, replace the faulty relay.
2. Resistance between terminals 85 and 86 (electromagnet) should be 75 ±5 ohms . If OK, go to Step 3. If not OK, replace the faulty relay.
3. Connect a battery B+ lead to terminals 86 and a ground lead to terminal 85 to energize the relay. The relay should click. Also test for continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, refer to Relay Circuit Test procedure. If not OK, replace the faulty relay.

RELAY CIRCUIT TEST

1. The relay common feed terminal cavity (30) is connected to battery voltage and should be hot at all times. If OK, go to Step 2. If not OK, repair the open circuit to the PDC fuse as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized position, but is not used for this application. Go to Step 3.
3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the energized position. This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the open circuit to the starter solenoid as required.
4. The coil battery terminal (86) is connected to the electromagnet in the relay. It is energized when the ignition switch is held in the Start position and the clutch pedal is depressed (manual trans). Check for battery voltage at the cavity for relay terminal 86 with the ignition switch in the Start position and the clutch pedal is depressed (manual trans), and no voltage when the ignition switch is released to the ON position. If OK, go to Step 5. If not OK, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition switch is OK, see the Ignition Switch Test procedure.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. It is grounded through the transmission range sensor only when the gearshift selector lever is in the Park or Neutral positions. Check for continuity to ground at the cavity for relay terminal 85. If not OK with an automatic transmission, check for an open or short circuit to the transmission range sensor and repair. It is grounded by the PCM if the conditions are right to start the car. For automatic trans. cars the PCM must see Park Neutral switch and near zero engine rpm. For manual trans. cars the PCM only needs to see near zero engine rpm. To diagnose the Park Neutral switch of the trans range sensor refer to the transaxle section for more information. Check for continuity to ground while the ignition switch is in the start position. If not OK and the vehicle has an automatic trans. verify Park Neutral switch operation. If that checks OK check for continuity between PCM and the terminal 85. Repair open circuit as required. If OK, the PCM may be defective

This should get you going on the diagnosis.

Thread: '05 EXL won't start - HondaSUV.com Forums

just because. the glow plugs are new, does not mean they work correctly, not at all. (yes, they can have weak or now power to them)
1: glow plugs work. really.
2: fueling correct. (fuel filter new, ?)
3: hearty battery and starter cranks nice and fast.

1,2,3, if not scan it.

Hi Allen, Make sure that the battery terminals are clean or better still replace them. check the connections on the battery and on the starter motor. If everything seems good the problem may well be with the starter solenoid and the contactors inside the unit. Regards John

Check your battery to make sure it has at least 12 volts then check the battery cables for corrosion or poor connection if all checks out ok then the starter solenoid is the problem.

Ok does the engine turn (easely) when you start it up, if yes, then you got you're self a "crank but won't start" condition. That is a little more complicated but if it simply won't turn when you start then you got a "no crank" condition witch is preaty simple.
First be absolutely sure that you're battery is good, try an other battery on it, one that you know is good. If it starts, change you're battery. I've often seen batterys that charge but go completely dead a soon as you take the charger off of them.
Second, verify the wiring, simply inspect the cable that goes directly to the starter for a cut or damage, also don't forget to check out the engine to body ground, witch usualy corodes and cuts (it's located near the crankshaft balancer and goes directly to the boby) Repair if neaded. Also verify that you're starter relay clicks when you start. If it does not clic, then you got a burned out fuse (fuse #6 in underhood fuse block), a faulty circuit or a faulty relay (underhood fuse block)(can try an other similar relay to verify). You can also try to bypass the starter circuit by simply using a screwdriver to jump the current from the positive pole (big red wire) to the "s" pole (small purple wire) of the starter. Use caution cause sparks will fly and engine may start. If the engine starts, then you know for sure the trouble is in the control circuit.
Third, verify that you hear the starter solenoid clic when you start. Have one of you're buddys start the truck and listen for a loud and clear clic (It is realy loud) If it does not clic at all or is not loud, and all the wiring and relay is ok, then the starter may be the cause (usualy only the solenoid gives away, witch can be changed seperatly)
Good luck, hope this will help

Is your charger working? Try jump starting it.

check battery voltage, if battery voltage is ok, you may need to check fuses under hood on passengers side, if start fuse is ok, you may need to have your starter replaced

Battery terminals like bad or corroded. Replace, and you should be fine.
