My 93 nissan altima stalled while driving and will not start back. put on a new coil, new fuel pump. still will not start. is it the crank sensor or distributor?


First, verify all connections at distributor (both ends of each cable) are securely connected and inspect all lengths of each plug wire to make sure there are no major breaks, cuts, burns, abrasions that would be causing a short. Then, try another plug just to make sure it's not a bad spark/coil wire. If still no spark, then I would say rotor/distributor cap/distributor/ICM module (Ignition Control Module) is the problem. You can generally buy those parts seperate, or you can buy a whole distributor that typically has all combined. The ICM can usually be removed without too much difficulty and taken to an autoparts store for a test, but not always. If you go with the "piecemeal" solution, start with ICM test (if removable), then rotor cap, then move to distrubutor cap. If nothing has worked to this point, you can replace the distributor, but you have already bought everything BUT the actual distributor. It would make sense to price everything seperately versus cost of new distributor...up to you.

If you do replace the distributor, be absolutely sure to mark the position/direction the rotor cap is pointed on old one, so you can re-install the new one in exact same position. Otherwise finding TDC (top dead center) on #1 cylinder is another whole process.

I need the diagram for plug wiring for 1992 ford tempo


Firing order is 1-3-4-2 Please rate if this helps

Installation of wires
  1. Whenever a high tension wire is removed for any reason from a spark plug, coil or distributor cap, or a new high tension wire is installed, Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent must be applied to boot before it is reconnected. Using a small clean tool, coat entire interior surface of boot with Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent.
  1. Insert each wire on proper terminal of distributor cap. Ensure wires are all the way down over their terminals. The No. 1 terminal is identified on cap. Install wires starting with No. 1 terminal.
  1. Remove wire retaining brackets from old high tension wire set and install them on new set in same relative position. Install wires in brackets on valve rocker arm covers.
  1. Connect wires to proper spark plugs.
  1. Install coil wire.


Installation of distributor
Before installing distributor, visually inspect distributor. Inspect O-ring. It should fit tightly and be free of cuts. The drive gear should be free of nicks, cracks and excessive wear. Rotate distributor drive shaft. It should move freely, without binding.
  1. To install distributor correctly, No. 1 piston must be at Top Dead Center (TDC) of compression stroke. Remove No. 1 cylinder spark plug and rotate engine clockwise until No. 1 piston is on the compression stroke.
  1. With No. 1 piston on compression stroke, align timing pointer with TDC on the crankshaft damper.
  1. Align locating boss on rotor with hole on armature. Fully seat rotor on distributor shaft.
  1. Rotate distributor shaft so blade on rotor is pointing toward mark on distributor base, that was previously made in Step 2 of the Removal procedure.
  1. While installing distributor, continue rotating rotor slightly so leading edge of the vane is centered in vane switch stator assembly.
  1. Rotate distributor in block to align leading edge of vane and vane switch stator assembly. Verify rotor is pointing at No. 1 mark on distributor base. If vane and vane switch stator cannot be aligned by rotating distributor in cylinder block, remove distributor enough to just disengage distributor gear from camshaft gear. Rotate rotor enough to engage distributor gear on another tooth of camshaft gear. Repeat Step 1 if necessary.
  1. Install distributor hold-down clamp and bolt. Tighten bolt, but leave it loose enough to rotate distributor.
  1. Install distributor cap, No. 1 spark plug and ignition wires. Check that ignition wires are securely connected to the cap and spark plugs. Tighten distributor cap hold-down screws to 2.0-2.6 Nm (18-23 lb-in).
  1. Reconnect distributor to wiring harness.
  1. Set initial timing according to procedures found in Section 13A of the Powertrain Control/Emissions Diagnosis Manual .
  1. After timing is set, tighten distributor hold-down bolts to 23-34 Nm (17-25 lb-ft).
  1. Recheck initial timing. Adjust if necessary.

I have a 1993 chev pick-up v6 4.3, i just installed new spark plugs,new plug wires, distributor cap and rotor button.All plug wires are back in the right position,and i used the firing order 1-6-5-4-3-2...


This diagram is for 1998-1995 Chevy 6 cylinder 4.3L engines.
Your got the firing order exactly correct, at 1-6-5-4-3-2, but here's the thing to double-check:
The distributor rotation is clockwise (note badly rendered arrow in picture).

Since you probably got everything right, then you're left with really unusual/rare causes of
failure of the ignition system:
(a) rotor button misaligned/failing to make contact?
(b) rotor button not pressed onto distributor shaft far enough therefore failing to provide correct
proximity to distributor cap contacts when coil fires
(c) coil wire or contact loose/disconnected - press coil wire firmly down into distributor cap.
(d) distributor shaft of other damage caused during installation of rotor.
(e) spark plug wires defective from factory
(f) spark plugs defective from factory
(g) battery low - may need a charge to start
(h) ICM (ignition control module) failure - hook up your HEI (high energy ignition) tester, and
watch the quality of the spark on each cylinder.
(i) fuel problem? If spark is being properly delivered, its gotta be a fuel problem...
(j) distributor cap not screwed down flush to top of distributor? maybe just on one side?

Inspect the inside of the distributor cap - if there are lots of little metal bits all over the inside
of the distributor cap, then you know you have a misalignment of some type in there, and the
rotor and cap are destroying each other. normal operation will throw a quota of spark-ed off
metal bits inside the distributor cap, but since your cap is brand new, your attempts to start
the engine should have rotated the distributor so few times, you should see no metal debris.

Inspect the distributor cap contacts to see if any spark marks are more of less in the middle
of the cap's proper "contact zone". If not, you've diagnosed an internal misalignment, which
you know how to correct.

Had sparks from coil, bought new coil same problem, bought new distributor, now car will not even start


By distributor, is that the cap or the whole piece of aluminum- housing with stator assembly/ control module/shaft/rotor/cap, the whole sha-bang.
If it was the "whole" distributor & If it ran before you put the distributor in & you only had sparks then the distributor was installed wrong.
Check for spark at the end of the plug wires. If you have spark then its more likely the distributor is in wrong &/or the firing order is off.

How to install cap and rotor on a 2000 chevy blazer 4.3ltre v-6


Disconnect the wires and take pictures with cell phone for reference to ensure you don't cross them when reinstalling the new distributor cap. Remove the two torque screws in the distributor cap and remove the distributor cap to access the rotor. Remove the rotor by lifting straight up and inspect the distributor for any condensation and corrosion. Clean the breather screen at the bottom of the distributor before installing the new rotor which just slides back in place. Install the new distributor cap and tighten the new torque screws, make sure you do not over torque the screws since the distributor housing is plastic and prone to stripping. Reattach the spark plug wires and start the engine and idle for 5 min and go for a test drive. Good luck and you may want to also buy spark plug boot lubricant to ensure the spark plug wires are fully installed when placed back on the new distributor cap and recheck connections after test drive. Keep me posted, be glad to know your blazer is running 100% and please rate.

    Distributor Cap grey_line.gif Inspect | Replace The distributor cap should be removed for visual inspection. Check the cap for:

    0900823d8004cf5d.gif

    Inspect the distributor cap and rotor. Courtesy of American Honda Motor Co., Inc.
    • Distributor cap locating tab. This tab assures proper location of the cap onto the distributor housing.
    • Distributor cap holddown. The distributor cap must be securely attached to the distributor housing to prevent contamination and to assure its location.
    • Dirt and water in the cap. These contaminants will require additional voltage in order to fire the spark plug. If available voltage is not enough to overcome this resistance then no spark will occur at the spark plug.
    • Center carbon insert. All of the high voltage coming through the coil on its way to the spark plug must pass through this insert. Any additional resistance caused by wear or contamination can cause the engine not to start or to misfire.
    • Tower inserts. The inserts are made from aluminum or bass so it is possible for them to oxidize. Aluminum oxide is an abrasive that can cause excessive damage to the distributor. If the insert is made from brass then the oxidation will appear green in color.
    • Cracks. If any cracks are present on the distributor cap then replacement of the part is required.
    • Carbon tracking. Carbon tracking indicates that the high-voltage of electricity has found a low-resistance conductive path over or through the plastic. The result is a cylinder that fires at the wrong time, or a misfire.
    Also check for:
    • Physical or electrical damage is easily recognizable.
    • Electrical damage from high voltage can include corroded or burned metal terminals and carbon tracking inside distributor caps.

    0900823d8004cf5e.gif

    Things to look for when inspecting a distributor cap.
    • If the distributor cap has a mild buildup of dirt or corrosion, it should be cleaned. If it cannot be cleaned up, it should be replaced. Small round brushes are available to clean cap terminals.
    • Wipe the cap and with a clean shop towel, but avoid cleaning these components in solvent or blowing them off with compressed air, which may contain moisture. Cleaning these components with solvent or compressed air may result in high-voltage leaks.
    • Check the distributor cap and housing vents. Make sure they are not blocked or clogged. If they are, the internal ignition module will overheat. It is good practice to check these vents whenever a module is replaced.
    Replace Distributor cap replacement instructions vary, so always follow the manufacturer's instructions.
    General replacement procedures are as follows:
    • For spring-loaded caps, unsnap the clips and remove the cap. When installing the new cap, make sure the clips are snapped back into place.
    • For spring-loaded j-hook caps, push down and turn. It will unlock. Lift up to remove it. Position the new cap in place, then push down and turn to lock.
    • For caps with screws, use a screwdriver to loosen the two screws. Install the new cap and use the screwdriver to tighten the screws. Don't overtighten.
    It is a good idea when replacing the distributor cap to remove the cap with the ignition wires attached. After you have installed the new cap, transfer the wires one by one onto the cap in their correct position. This way the firing order is accurate. If, for some reason after you replace the distributor cap, your vehicle does not function normally, check your firing sequence.
    The distributor cap is mounted on top of the distributor assembly and an alignment notch in the cap fits over a matching lug on the housing. Therefore the cap can only be installed in one position, which assures the correct firing sequence. There is a tab or notch somewhere on the distributor body that must align somewhere on the distributor body that must align with a corresponding tab or notch in the cap. Once again, do not force something.
    The rotor should be inspected and/or replaced when the distributor cap is replaced.

    Firing Order Each cylinder of an engine must produce power once in every 720 degrees of crankshaft rotation. Each cylinder must have a power stroke at its own appropriate time during the rotation. To make this possible, the pistons and rods are arranged in a precise fashion. This is called the engine's firing order. The firing order is arranged to reduce rocking and imbalance problems. Because the potential for this rocking is determined by the design and construction of the engine, the firing order varies from engine to engine. Vehicle manufacturers simplify cylinder identification by numbering each cylinder.

    0900823d8004cf75.gif

    Examples of typical firing order.
    Regardless of the particular firing order used, the #1 cylinder always starts the firing order, with the rest of the cylinders following in a fixed sequence. The ignition system must be able to monitor the rotation of the crankshaft and the relative position of each piston to determine which piston is on its compression stroke. It must also be able to deliver a high-voltage surge to each cylinder at the proper time during its compression stroke. How the ignition system does these things depends on the design of the system.
