    i'm having the same problem terminals are clean,battery is fully charged, ive even tried running a jumper from the battery to the starter also.
    still only get a clicking from the starter and the passenger side fuse box under the hood.
    any ideas i,m totally stumped

    I seem to have the same problem with my 94 cutlass as well. And recently I changed the battery and new positive and negative wires. It seems that where the positive cable from the battery connects is a fuse box on the driver side of the engine compartment. Like for jump starts. Well when I'am getting the clicking noise, I pop the hood, get out and wiggle the wire where it connects to that fuse box and it will start right up after that every time.

    My question is that, now I am having transmission issues. All the gears are still there. But when I proceed from a dead stop the car wants to shift before nessecary and by the time I'm goin about 30mph the car is already in over drive and does not wanna come down through the gears. If I come to a complete stop, then the car will start back at first like normal. And if I manually move the gear select from first up through the gears almost like a "autostick" then the car drives just fine. If i bring the gear shift down, like from 3rd to 2nd, then the car shifts very violently, so I'm not driving the car and all the shops I call want a large fee to diagnose the prob. Any thoughts??

    well i have been a ASE mechanic for 15 years and never put a ecm in an olds. To me what you are explaing with the relays it sounds like the battery is dead or very weak. Does the car crank over at all ? if not see if the head lamps come on and are bright. If tehy are dime or dont work if you have a volt meat put it on the battery and see what the voltage is

Clean and tighten your battery cables. I have a 95 cutlass supreme that did the same thing. If that doesnt fix it, the ECM may be to blame. When the ECM went in my Olds, the car would fire but only run for 2-3 seconds. Once I had the ECM replaced it was fine

2008 Holden Colorado wont start and no dash lights


Check your ecm fuse, or your main power relay fuses, basically just check all the fuses under the dash and under the hood, if there are a few relays under the hood, you can try and swap the ac relay with the power relay as long as they have the same numbers on them. If all the fuses are good, it is most likely a relay, or the ignition switch itself

08 chevey colorada wont start or turn over


Is there a security light lit on the dash or a picture of a padlock an car lit ? How's the battery an cable connections ? Is there power an control from the PCM at the starter relay in the under hood fuse / relay box ? Do you know what is involved in the starting of your vehicle , the electronics ?
Circuit Description (Key Start)
When the ignition switch is placed in the Start position, a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the engine control module (ECM) notifying it that CRANK has been requested. The ECM verifies that the clutch pedal has been depressed or the transmission is in Park or Neutral. If it is, the ECM then supplies 12 volts to the control circuit of the STRTR relay. When this occurs, battery positive voltage is supplied through the switch side of the crank relay to the S terminal of the starter solenoid.

My 2009 dts Cadillac started yesterday but this morning went out to start it it wouldn't start lights on in and out just won't turn over


Is there a security light lit on the instrument cluster ? could be a anti-theft system problem ! Three electronic control modules involved in the starting circuit of this vehicle , BCM - body control module , PCM -powertrain control module , an theft deterrent module !
The immobilizer system functions are provided by the theft deterrent module (TDM) and the engine control module (ECM). When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coil surrounding the ignition lock cylinder. This exciter coil is part of the TDM. The energized transponder transmits a signal that contains its unique value, which is received by the TDM. The TDM then compares this value to a value stored in memory. If the values match, the TDM will send the prerelease password via the serial data circuit to the ECM. If the transponders unique value is incorrect, the TDM will send the fuel disable password to the ECM.
When the ignition switch is placed in the Start position a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the engine control module (ECM) notifying it that CRANK has been requested. The ECM verifies that the transmission is in Park or Neutral. If it is, the ECM then supplies 12 volts to the control circuit of the starter relay. When this occurs battery positive voltage is supplied through the switch side of the starter relay to the starter solenoid.
If you knew how , in the under hood fuse / relay box is the starter relay , it has a four pin socket when relay is removed ! Two should have battery voltage , one should show ground an one is control voltage from the PCM on pin 86 , pin 85 goes to ground. Pin . Pin 87 should have battery voltage an pin 30 supply's voltage to Fuse #24 marked STRTR in the under hood fuse / relay box ! Yea , if you look on the bottom or side of the relay the pins are marked ! Check for what is missing power or control an go from there .

Car cranks but wont start? No spark. Changed ecm relay no help. Ignition harness is good. No fault codes. Battery is good. changed ignition relay, no help. I think its the ECM but need more info to spend...


Yes, the ECM is the last thing to replace after all other possibilities. No spark could be bad ignition coil, bad Ignition Control Module (controls the coil circuits for spark), bad plug wires, the crank and cam sensors (for ECM to determine spark timing).

Check the ICM -it can be tested at a parts store. If good, check the crank sensor.

What suplies power to coolin fan relays? Then what do the relays send to? Just the Fan?


Get yourself a wiring diagram ,of at least the
circuits your working on

Have a local repair shop print what you need,
then you can do your own testing

Where is ecm on 95 gmc jimmy


The ECM on the jimmy, is located on the passenger side fender well by the overflow tank. But before replace the ECM, inspect the fuel pump and fuel pump relay. The ECM sends power to the fuel pump relay and if the relay has gone bad will cause the fuse to blow which will kill the the power to the ECM, in turn kill the electrical power to the ignition system.

Start by removing the fuel pump relay and swap it with another relay and see if the fuse will blow again, if is does. Disconnect the fuel sending unit wire harness at the frame and see if the fuse blows again, if the fuse stays good. Chances are your fuel pump has gone bad or the fuel filter is dirty/clogged causing your fuel pump to draw more amp and will need to be replaced or the wire harness from the frame to the sending unit has a short which is common on older Jimmy's.

Here is a link to the electrical harness throughout the Jimmy.

2001 blazer wont start . gas gauge quit working ,fuel pump wont work will work suppling power to port in fuse panel. ecm fuse ok,relay ok


Sounds like the ignition switch has gone bad and will need to be replaced. Turn the ignition switch to the on position again and check to see if there is power to other items like the transmission and accessories. If there are a few items that are not working, good chance that the ignition switch has gone bad and is there any security light on the dash flashing???

Thank you for using fixya and keep us posted.

2007 Buick Lacrosse low beam headlights both went out at once. Doesn't appear to be the bulb. Also checked the fuses under the hood and those both appear OK too.


The relay under the hood may have gone out. We had the same problem on our 2007 Buick LaCrosse CX. The bulbs were fine, high beams worked, all turn signals and everything except the low beams turned on. Turns out the relay had gone bad.
