Found a "failure to start test" procedure for you at:
http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0900c15280078ff5

to view Autozone's repair database, register free at www.autozone.com.

My first thought - engine not grounded - find/check/install engine ground strap/wire.

Just in case - here's the AutoZone "Failure to Start" page:

  1. Using a Digital Volt/Ohmmeter (DVOM) measure the voltage from the negative (-) battery terminal to the positive (+) battery terminal. The voltage should be at least 12.66 volts. This amount of voltage is necessary for an accurate inspection of the system.
  2. Detach the ignition coil harness connector.
  3. Connect a suitable test light to the B+ (battery voltage) terminal of the ignition coil electrical connector and ground. The center terminal of the connector supplies battery voltage.
  4. Turn the ignition key to the ON position. The test light should flash on and then off. Leave the ignition key ON .
    1. If the test light flashes momentarily, the PCM grounded the ASD relay. Proceed to the next step.
    2. If the test light did not flash, the ASD relay did not energize. This is caused by either the relay or one of the relay circuits.

  5. Crank the engine. (If the key was placed in the OFF position in Step 4, turn the key to the ON position before cranking. Wait for the test light to flash once, then crank the engine).
    1. If the test light momentarily flashes during cranking, the PCM is not receiving a camshaft/crankshaft position sensor signal.. A DRB or equivalent scan tool must be used to test the sensor and related circuitry.
    2. For 1995 vehicles, if the test light did not flash during cranking, unplug the camshaft position sensor connector. Turn the ignition key to the OFF position. Turn the key to the ON position, wait for the test light to momentarily flash once, then crank the engine. If the test light momentarily flashes, the camshaft position sensor is shorted and must be replaced. If the light did not flash when the engine was cranked, the cause of the no-start condition is in either the crankshaft or camshaft position sensor 8-volt supply circuit to the crankshaft position sensor 5-volt output or ground circuits. Use a DRB or equivalent scan tool to test the crankshaft position sensor and related circuitry.
    3. For 1996-99 vehicles, if the test light did not flash during cranking, unplug the crankshaft position sensor connector. Turn the ignition key to the OFF position. Turn the key to the ON position, wait for the test light to momentarily flash once, then crank the engine. If the test light momentarily flashes, the crankshaft position sensor is shorted and must be replaced. If the light did not flash when the engine was cranked, the cause of the no-start condition is in either the crankshaft or camshaft position sensor 8-volt supply circuit to the crankshaft position sensor 5-volt output or ground circuits. Use a DRB or equivalent scan tool to test the crankshaft position sensor and related circuitry.

    Where the 1998 Plymouth Neon repair guide says 'DRB scan tool' - this is
    a $7600 ODB-II scan tool used by dealerships, whereas most serious
    Shadetree mechanics own $100-$180 auto parts store scan tools.

  • John Jon Jan 02, 2011

    Yes i have that $7600.00 scan tool I'm in a Chrysler dealer ship for 25 years I'm a senior mechanic.I have 100% professional tools and techniques added knowledge hands on dealing with these issues 100 and 10 times over i help out on here to do good deeds.

I'm losing power and showing low oil pressure. If I stomp on her she runs ok until I come out of third gear. Takes a long time to get from 50 to 70 and it feels like the truck is giving me everything she...


Check compression in each cylinder., sounds as if it might be piston rings.oil thins as it warms so the drop in pressure seems to point to loss of compression .i take it it doesn't blow smoke out of exhaust?

5.3 liter Chevy engine #1 Cylinder not firing at idle


My opinion...

Year? Miles?

There's no way I'd dive into a "HEAD GASKET"
diagnosis without pressure testing the cooling
system and (wet/dry) COMPRESSION testing
the whole engine...

Even if it is a "HEAD GASKET"... the entire engine
might be ready for a REFRESH... and tossing a new
Head gasket into a TIRED ENGINE not insubstantial
(a lot of wasted time & money)...

Come back with some compression numbers...

but don't bother with any of this if your engine oil has water in it.

I have a 1999 Mitsubishi Galant and need to know how to put on a valve cover gasket. Oil is leaking out and dripping and it's causing it to burn and smoke comes out of the car.


Instructions
    • 1 Allow the car to cool. Disconnect the battery terminal. Remove the right side vent screen top extension. Disconnect the ignition coil with power transistor and its wiring and brackets.
    • 2 Disconnect the left hand side coil wires and spark plug wires. Remove the spark plug wires, valve cover bolts and the valve cover. Unplug the electrical connections from the intake manifold runner control actuator. Unfasten the actuator retaining the screws, right bank heated oxygen sensor front and rear.
    • 3 Remove the heated positive crankcase ventilation (PCV) valve. Remove the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor. Disconnect the ignition coil with power transistor and its wiring and bracket. Remove the valve cover bolts, the valve cover and the old valve cover gasket. Clean the valve cover seating area with automotive engine cleaner and place the new gasket in the gasket seating area.
    • 4 Replace the parts that were removed and disconnected by reversing the steps. Replace the valve cover gasket and tighten the bolts, in sequence, ensuring not to over tighten. Put back the ignition coil with power transistor and its wiring and bracket, the heated positive crankcase ventilation (PCV) valve, the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor.
    • 5 Add oil to the car. Start the car and let it run at idle for a while to check for leaks..

Engine missis at 2-2 half rpm under load.


Ok, if the car is misfiring it probably has a bad air/fuel mixture which can cause fouled spark plugs. The causes of a bad air/fuel mixture would could be a bad oxygen sensors or a bad engine coolant temp sensor. But that car is known for having bad head gaskets. What is probably happening is coolant and/or oil is leaking into the combustion chamber. you can check under the cars engine, where the head meets the block, for oil or coolant leaks where they attach. Or check the coolant for CO2 with a CO2 tester (found at auto parts store) and check for low oil. If it tests positive for CO2 in the coolant then its a blown head gasket. once you get the problem fixed you will probably need new spark plugs and possibly a catalytic converter (the longer it misfires, the more fuel will be burned on the cat filter and it will enventually melt)

97 saturn sl2 died while driving , pulled first spark plug boot and found filled with oil


The head gasket needs replaced. This particular Saturn is known for having this exact problem, and 9 out of 10 times, replacing the head gasket fixes it. I just did it myself for $35.

Go to checker/autozone and get a head gasket (should just need the gasket and not the entire kit) and a tube of RTV silicon grease to help make the seal.

Unhook everything from the engine (plugs, wires, etc, and unscrew the head. There should be about 10 or so screws surrounding the black plastic head cover. You'll find things a mess in here, but clean it up best you can. Remove the old gasket and clean the entire gasket area completely and make sure its dry. Put down your RTV grease, the new gasket, some more RTV, and screw the head back on. MAKE SURE YOU DON'T SCREW IT TOO TIGHT. The screws only need to be snug. Tighten it like you would a spark plug. Put everything back together and you should be good to go. Might run like **** the first half mile or so.

I have a 1984 Ranger 2.0 engine. It belonged to my girlfriend who let it sit up a while. I got it to crank and run and started driving it. Everyonce in a while it would loose power and one time backfired....


check the oxygen intake system. I'm not sure but your car is eighter the caburator or fuel injected.

in anycase the white smoke and cuting off, backfiring and loosing power is cause of the caburator or oxygen sensor (in fuel injected cars).


get your oxygen intake system serviced. it fits your problems perfectly. seeing the age of your car I'm betting its caburator, have that serviced or replaced.

I have a 2002 Nissan Altima 2.5L that is leaking oil into the spark plug tubes; can these seals be replaced or does the valve cover have to be replaced?


Yes, you need a Rocker cover (valve cover) Gasket kit. Remove the valve cover, remove all old O-rings and cover gasket, clean grooves and mating surfaces without gouging or scratching them, put the new gaskets on as per factory recommendations, tighten to the proper torque and you're done. The spark plug holes in the cover are part of the valve cover gasket kit. Any Napa, Car Quest, Pep Boys, Auto Zone will have it.
