SOURCE: wont start cold has new

Start by checking your coolant temp sensor. If it is stuck in the "hot" position, it will not provide enough fuel to fire. Just like a choke on a carburettor. Check that out and replace as necessary and let me know what you find. If that checks out good, we will move on to other items.

SOURCE: 1995 mazda b3000 wont turn over. Worked fine till this am. Dash lights etc work. Fuel pump runs. Has new starter. Nothing cranks. Checked terminals, relays etc. All look ok. What can it be?

Starter Circuit B3000

Using the diagram in the Link above, do the following:

1. The simplest way to half-split the problem is to determine if the problem is in the starter or in the circuitry. If the starter is accessible, take a screwdriver (I know this sounds crazy, but it works), and short the "B" and "R" terminals. This bypasses the ignition circuit and puts battery voltage directly to the starter. There will be a large spark, so don't freak. Be careful not to short anything to the engine block or vehicle body! You only need to do this long enough to hear the solenoid engage and the motor start to turn. If the starter kicks in, the you will need to troubleshoot the circuit. If not, then replace the starter. CAUTION!!!! If you have a manual transmission, ensure you are in NOT IN GEAR when you do this, or the vehicle will attempt to move. Also, DO NOT HAVE THE IGNITION KEY ON when you do this.

2. If the starter kicks in, then are four, perhaps five items to consider.

1. The least likely are the actual wires themselves. Yes they can fail, but there are no moving parts here, so they are the last to be suspected.

2. Starter relay. Many people do not know that this relay exists. They think the ignition switch goes directly to the starter solenoid. However, manufacturers have found that the high current of the solenoid damages the ignition switch electrical contacts over time. They added a relay to take the punishment as it is easier and cheaper to access when it fails (and they will eventually fail from arcing).

3/4. The Park/Neutral switch (if AT) or the Clutch Switch (if MT). These are more common and are often not thought of. If the vehicle is automatic, try starting it in Neutral. If that works, and it doesn't in Park, the switch is definitely bad. If it doesn't start in either position, it could still be the switch.

5. Anti-theft relay. If your truck has the anti-theft system.. this relay could be failing,

6. The ignition switch itself. Not necessarily the least likely item to fail, but certainly the least desirable. It is the hardest to access, and the most expensive to replace.

All this said, if you must troubleshoot the circuit, you should start from the starter and work back, using a test light or multimeter. Hook to the INPUT of each suspected component in the path, then attempt to start the vehicle. If there is no indication, move back one item and try again. When you get the indication, then you have isolated the item.

EXAMPLE: Place test light on "B" terminal of starter. Crank engine. No light. Move to input of starter relay. Ensure battery voltage is present on "R". then connect to the relay coil input (R/LBL) [Note: The letters are not labeled pin numbers, they are wire colors] Try to crank again. You have indication. That means to circuit works to here. The starter relay therefore is bad.

Testimonial: "great advice. I lucked out, tiny little wire on starter relay (I think) on wall between battery and relay box. But this info did get me looking there."

Spins over, wont fire. New fuel pump, ignition coil, and ICM. Cleaned cap and rotor. still wont fire


Is there spark getting to the spark plugs ? Is there fuel pressure, check with fuel pressure gauge . Is there an anti-theft system light lit on the dash ? SECURITY light ? Can a scan tool communicate with the vehicle modules ? PCM , BCM , ABS , Air bags , etc... You should test before replacing parts ! No Start Diagnostic Basics EricTheCarGuy

Why is my truck not working?


Year make and model are essential information. But it could be a fusible link if it's an older vehicle. Near the battery there should be wires that have a big molded rubber part inline on the wire. See if you can take a test light and poke through the insulation on the far side of the wire and see if there is one where the light does not light up. They sell them at auto parts stores. If it is a newer vehicle it could be a bad main power relay, or a bad body computer. And that's nearly impossible for me to help with online

My 99 gmc 5.7 vortec got turned when the distributer was out now the oil pump shaft wont line up to put the distributer wont line up .. whats the best way to line everything back up and get the timin


If the Pontiac engine is similar to the small block Chevy, you have, I believe, a hexagonal shaft that runs from the end of the distributor shaft down to the oil pump. This is turned when the distributor shaft is turned by the meshing gears on the camshaft and distributor shaft. I would say that you are probably going to have to re-time the engine. Find TDC, then replace the distributor. It won't matter a whit to the oil pump if the gears are one or two teeth off, but it will matter a great deal if you distributor is not installed so it can be adjusted a few degrees when you get to "fine timing" the engine.

You should be able to download information on how to time the engine (finding TDC, etc.). Failing that, a trip to the library may be in order.

The dash gauges all work , fuel pumps are both good , the fuel pumps wont come on and the truck trys to fire when i turn the ignition on but wont , could this be a fuel regulator


did you check the fuel pressure pump on the frame rail for power and ground? have you verified no ignition spark to the spark plugs? have you checked for fire from the coil to the distributor cap? does the check engine light come on when you turn the key on? have you check for injector pulse and power at the fuel injectors? if the fuel pump won't come on and you have no ignition fire and no injector pulse, all of these systems are triggered by the ECM.

Car wont start, r & r'd starter, connections clean, battery connections good no corrosion, most of the instrument panel precheck lights etc but fuel gauge is in op


Check to make sure you're getting power to the fuel pump.

The sending unit for the in dash gauge is a part of the fuel pump assembly.

If you don't have power to the fuel pump, it won't run, consequently no fuel is pumped to the engine to allow it to start.

My 1999 chevy blaxer ls turns over but will not start, i can smell the gas but it just donesn't start, what could be the problem?


A lot of solutions for this. It could be fuel pump, timing, crankshaft sensor,. Question? Was the check engine light on before it quit on you? Hmmmm. If so we need to scan the codes to find out whats wrong. If not we need to find out if the problem is fuel related or electrical. How many miles on the vehicle? Good luck!!!!

You will have to have the dealer reset the security light to restart vehicle.Check all engine and chassie grounds because this is where the lighting would exit the vehicle.It sounds like a ground burnt through.

I have a 1992 Toyota MR2, one evening I cam out to go get a movie, went to start the car and all that happened was the starter started clicking rapidly. I turned the ignition switch off and the starter...


This sound like a more common issue than we in the mr2 community would like to see. The cars are old and the ground wires tend to wear out. But normally the gas pedal cable becomes the place were it grounds out and start a fire. get a cheap ground wire kit for the engine compartment as well as put a few on the battery. Also check existing ground wires. Hope this helps!

if it wont hold an idle then one or more of the cylinders are probably too low or high in compression and if it's backfireing then the ignition timming could be off. I would take a compressin test of all cylenders and if they are all in range I would hook up a timming light to se if the timming is out
