On your fire wall where the wires come out of the truck you will have what is called an inline fuse. It is gone and there is no way to replace it. It will be black in color and should be on a orange wire. It is about an inch in leangth. Cut it out and put a new inline fuse you can buy at ya auto parts store for around 5 bucks. It should have a 20amp fuse to it. This should take care of ya troubles.

I think for sure that the timing belt has jumped a tooth. This can happen if your water pump, or your idler pulley, which are driven by the timing belt, "locks up" for a second. Best advice: replace the timing belt (you should not "reuse" it, as once it slips a tooth, that tooth is now weakend. Also, check the feel of the water pump impeller-gear...if it feels gritty or does not spin freely, replace the water pump while you are in there. It's not much more work. Also check the IDLER pulley for the same feel. If it feels bad/does not spin free, replace it. One or the other caused your problem.
Let me know how it turen out.

SOURCE: engine wont crank

im looking at that circuit , on the start relay on your radiator support , red is always hot via fusible link , purple to solenoid as you say , orange/black wire should be hot in run or start mode , if it is not the fuse for that wire is PCM/ABS 10 amp located fuse block in driver door jam , it does go through the nuetral saftey switch , the yellow wire going to the PCM must ground that relay to activate start mode . last note there is a PCM/CRANK fuse in the driver door jam also , 10 amp , if all this is good i would like to hear more . 1 more note about the nuetral saftey switch is the pink wire going in and the orange/black wire coming out should have continuity in park and nuetral ....let us know thanks

SOURCE: 350 Chevy starter wiring diagram needed

IF YOU HAVE A POINTS TYPE DISTRIBUTER, THE WIRING WILL BE: TO ENERGIZE THE STARTER SOLENOID A LARGE, ABOUT A NUMBER 12 OR 14 GAUGE WIRE WILL GO TO THE INNER MOST SMALL TERMINAL ON THE STARTER SOLENOID. IT MAY BE PURPLE IN COLOR. THE SECOND SMALLER WIRE SHOULD GO TO THE OUTER SOLENOID TERMINAL AND GO FROM THERE TO THE + TERMINAL ON THE IGNITION COIL. THIS IS FOR BY PASSING THE RESISTOR WIRE FROM THE STARTER IGNITION SWITCH. THE LARGER BATTERY CABLE WILL GO TO THE UPPER TERMINAL ON THE STARTER SOLENOID. THERE MAY BE AN ADDITIONAL BATTERY FEED WIRE TAKE OFF FROM THE STARTER BATTERY TERMINAL POST ON THE SOLENOID FOR OTHER ACCESSORIES. THIS TYPE OF SYSTEM (POINTS TYPE) WAS TYPICALLY DONE AWAY WITH IN 1975 WHEN THE HEI DISTRIBUTOR CAME OUT.

I would suspect the ignition control if you have already replaced all that stuff. I personally would replace it with an MSD ignition for better running and fuel mileage, but the ignition module should be a whole lot cheaper.

Can a starter drop dead with no previous indications of it going bad?


Hi Frank , what make vehicle ? Do you have any warning lights lit on the dash , SECURITY maybe ? Check engine light ? Did you check to see if there is battery voltage at the starter solenoid ? Did you check if there is A starter relay ?

I don't know the 1999 Chevrolet Cavalier, but that shouldn't matter.
Starters have a very simple wiring.
The thing you have to do is find the solenoid wire because all the others go on the one terminal.
Start by attaching the main (thick) cable from the battery to the main terminal on the starter.
Then turn the ign. key on. Nothing will light up.
Try touching each of the smaller wires onto the main terminal until the ignition lights come on. Fit this one to the main terminal permanently.
Now that you have power to the ign. switch, you will be able to find the solenoid wire. It will help if you have a volt meter or test light for the next step.
With someone sitting in the car to work the ign. switch, you test each of the other wires as they turn the switch to the "Start" position. The wire that gets power to it is the solenoid wire and the ONLY one that doesn't go on the main Starter terminal.
The solenoid wire obviously goes to the terminal on the solenoid.

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.

I have a 2000 chevy malibu drove it for a few days then the other day went to start it turned the key no dash lights like the battery or any of the others that usually come on the mileage dont come on...


Did you check all the fuses under the hood? That's where the ignition fuses would be. The same "run" wire to the ignition coils, when the key is in on or run, or the same set of run wires out of the ignition switch both to the dash warning lights and gauges, and to the ignition system on the engine, well they're all the same power source, and more so the computer gets power from the ignition switch being on as exhibited by the check engine light turning on when key is turned to on.
It sounds like the ignition switch is either not getting full power in, or it's not sending power out as it should.
Check your other battery power-do you have headlights? That would be entirely separate from the ignition switch, but it verifies that battery power is getting to the fuse and relay block under the hood. Is the cranking speed normal? not too slow?

Without a voltmeter and a wiring diagram, you're in a bit of a fix. But I would be wondering why the ignition switch isn't sending power to the coil primary positive terminal, and why it isn't causing the fuel pump to be turned on, too.
Is your check engine light on with key on? The computer should sense ignition is on and briefly turn on the fuel pump through the fuel pump relay, on just long enough to pressurize the fuel line to the injector. But no fuel or fire-you'd better start by checking if the ignition switch has power in and power out, and work your way to the coil.

This could be many problems. A ground wire may have come off or your negative battery cable is loose. Check your relays and fuses as well. Have an autoparts store run a diagnostic.

1993 Ford F-750. 7.0 fuel inj. PFI type. No start, has good inj. pulse,psi good etc. No spark, reman. dist.,coil and firewall ign. module has been replaced. Both modules tested ok. Wiring-Help!!! ...


Hi, I do not have wiring diagrams for the F-750, but I'm assuming the ignition systems are similar for all trhe F series trucks. Are you getting battery voltage to the coil when the key is in run and start? If not, first verify the fuse is good. If there is a noise capacitor on the positive coil wire, remove it temporarily while troubleshooting. If that cap is causing low voltage to the coil, replace it. If you still cannot get power to the coil, the problem may be the ignition switch. If you have power to the positive coil terminal, pull the coil wire out of the distributor and lay it on the engine where it has about a quarter inch gap to engine ground. Turn the key on and momentarily jump a ground wire to the negative coil terminal to see if it will release a spark. If the coil will release a spark this way, the problem is back in the distributor. Was everything in there replaced? Please let me know if you have questions.

No spark in engine


Replace the coil wire. If thats not it? Is the coil wet? if it is? Its bad. Ignition module might be bad.
Make sure your getting power to the positive side of the coil when you turn the key on. Use a test light to ground from battery and probe to positive ignition wire going to the coil. The test light should go on when the key is on. If it does light? Your problem has nothing to do with anything inside the vehicle. Make sure all grounds are clean and tight in the engine compartment. if you have no response from the positive side or the coil ignition wire? Jump a wire with alligator clips one side to the positive on battery and the other on the positive side of the coil. Then try starting it. If it starts now? You have a broken wire some where between the coil and the ignition switch. I have had to replace a whole steering column because of this and it worked. but do all the cheaper stuff i had listed above .
Thanks i hope i helped with diagnosing with you.
Please leave me a good comment or feed back on here.
Thanks

Trouble code P0320 ignition/dist. engine speed input circuit


P0320 - Ignition / distributor engine speed circuit malfunction

The ignition engine speed sensor input signal to Powertrain Control Module (PCM) or Electronic Control Module (ECM) is continuously monitored. The test fails when the signal indicates that 2 successive erratic profile ignition pickup (PIP) pulses occurred.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- The engine may stumble or stall

When is the code detected?
The P0320 code is triggered when 2 successive erratic PIP pulses are detected.

Possible Causes:
- Loose wires/connectors
- Faulty Crank Position Sensors
- Arcing secondary ignition components (coil, wires and plugs)
- Low battery charge
- Powertrain Control Module

Possible Solutions:
- Resecure loose wire or connectors
- If battery charge is low, recharge or replaced battery
- Replaced crank position sensor
- Replaced starter motor
