Try to check the distributor caps for invisible breaks or cuts and clean the accumulated dirts in the contacts.

Hi,

The IGN B+12 missing when cranking is significant, it could possibly indicate a defective ignition switch. A test/temporary workaround is to wire the ignition B+12 in the engine direct to the battery's + terminal and and try again. In some instances, it could be fusible link. This would be the smaller wire other than the big starter cable on the + terminal of the battery. Often the connector before entering the main harness are corroded and therefore would require check/cleaning/replacement.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

    Hi again,

    Appreciate the quick postback.

    As to being a mechanic, started working on cars when contact points were still in use. Unfortunately, muscle cars from Chrysler, Dodge and Plymouth are not that common in my country except when joining "fun day" in Subic or Angeles (former American bases) where the US military personnel have an "informal" dragstrip.

    Have had my fair share of Japanese 4 cylinders, American straight 6 with an occasional sprinkling of small & big block V8s.

    Your concern is typical considering it is 1989. A temporary workaround (since ignition switches are rather expensive in my country) is to use a Bosch relay so as to remove the current/load from the IGN switch to the relay. Even if the IGN B+12 goes down a bit, the relay would still be pushing a full +12 to the ignition system. this is of course assuming that the battery is fully charged.

    Cheers.

    Have you tried applying battery voltage directly to the starter
    terminal, if not try doing that to see if the starter spins the engine
    over. If it does then there is a wiring problem between the starter and
    the ignition switch or the starter relay is bad. If it doesn't turn the
    engine over check the positive battery cable between the battery and
    the starter, do a voltage drop test between the two connection points.
    The starter will draw lots of current, about 200 amps and if there is
    any voltage loss between the battery and the starter it will not engage
    the solenoid.

    I'm thinking the starter relay is bad and they cost about $30 or possibly less

Will not start but turns over


Fuel or spark plug trouble could be a cause for an engine not starting. Check for spark plug spark. Remove spark plug wire and see if the wire makes a spark on engine when spark plug wire is energized. Do not tounch engine or come in contact so that you are shocked when testing for spark plug action. Check fuel pump to see if fuel is being supplied. Disconnect fuel line and place the fuel line inside a container to capture fuel. Do not cause a fire from loss of control of fuel line during trouble shooting.

Starts then shuts off


You should do fuel pressure testing , check for a good spark . Have a scan tool hooked up ,check for codes , look at engine sensor data parameters etc.... Look on youtube for diagnostic videos . engine dies etc... An check out basic electrical trouble shooting videos ,how to test fuel systems an ignition system testing . Find which system is causing trouble , then go to www.bbbind.com for free wiring diagrams . Then trouble shoot the problem .

Engine 4cy


misfire, at idle does cause, too low hot idle .
ever do a tuneup , the full 60k interval service? nows the time.
if it is tuned up. then trouble shoot misfire.
if you want to do that, post back. there are many tests.
most take tools, are you willing to buy tools. or do you want helpers
to just guess?
causes (macro)
1: a bad engine, (50 ways) but low compression tops list.
2: bad spark (tuneup, or failure) test spark.
3: bad fueling. (too much or too little) there are tests to do.

you have only 2 choices, guess, or tests.
which will it be.?

My first guess would be a crank or cam sensor is disconnected.
Or damaged.
Have you checked the computer for trouble codes ?

CAR TURNS OVER BUT WILL NOT START HOW DO I TROUBLE SHOOT FOR IGNITION COIL ISSUES..


have you tested each wire with a spark tester (available at a parts store for around $10) to verify a lack of spark? there are resistance reading for the primary and secondary circuits in the coils that are pretty accurate testing. but that info may only be available from a repair manual. however, you could remove the coils and test all in comparison to each other. no spark from ALL wires would suggest a possible bad crank or cam sensor, or even a bad ignition module

2000 honda crv willnot start-no spark


remove the ignition coil pack and have it tested at a local auto parts store. If its still good, try replacing the crank or cam position sensor. If you still get no spark, then you will need to follow up with the tech manuals for thorough trouble shooting instructions.

No spark


Check for signal from distrubutor as it acts as your igniter open and close switch or get a haynes manual from auto parts store to trouble shoot it multi meter required for ohm test and voltage drop test and test light. you may have power and ground but no signal. your igniter or incorrect gaps. Its a 20$ book with pictures....
