My 87' Supra isn't getting spark. I've checked visable fuses, had the coil tested, all the plugs, wires, are good, and the distributor cap and button appear to still be in good shape. Is there a way to self diagnose via: " pulling codes "?

It could be the throttle position sensor, this is a small electronic part that goes bad on pretty much every fuel-injected car eventually. I think it's located on the throttle body itself.

1992 geo storm replaced distributer have fire out of coil wire but no fire spark plug wire module in distributer checks out


storm is an ISUZU
and had 3engines,which one? below is off wiki on storm.
1.6 L SOHC 4XE1 I4
1.6 L DOHC 4XE1 I4
1.8 L DOHC 4XF1 I4


coil makes 50,000 volts (even 1kv makes fire, but is too weak spark
spark plugs dead , right? all 4 right?
ever do a 60k mile tune up ? if not why not, it gets new spark parts then..
also, if the cam timing is off. the dizzy sparks between towers
make the distributor useless, it cant distribute spark.
so the first tests are .
static ignition timing. (yes, a tool, called a timing light for $20)
if timing is good the the wires HV are bad.
if timing is bad, bingo..... this is the first test on any motor.
if the timing belt or chain on any SOHC or DOHC engine slips
the dizzy will be way to h3ll off.
learn to use a timing light, and works 100% cranking.

look at that distributor cap (replace it)
see the coil wire , center, that is at 50kv spark.
and see that rotor, if the spark is good at the cap pins 1 to 4
then the dizzy is timed.
if the spark dont reach the spark plugs that means
the wire are bad or the spark plugs are shorted, or both.
its that simple. using a real spark testing tools tells you the KV.
kv = kilovolts. the best tools $5 bucks have and adjustable gap
this car is not 100kv, like newer cars and must be set (tool) to 50kv or tad less to show full powerful spark.

take care not to get shocked, keep hands off the parts
as friend cranks (or remote start button tool)

1989 toyota land cruiser.driving on highway engine died.turns over good but wont start.has a full tank of gas.put in new battery and altenator a few weeks ago,been running fine.checked the fuses and found...


Hi.

Re:new battery and altenator
If engine turns over battery and altenator are OK.

Re:checked the fuses and found a few were blown.
Effectively those may be symptoms of a wiring problem. If a job had been carried recently, undoing and re-connecting the wires to access the part(eg. alternator) may have contributed to the problem.

Check all fuses, with attention to fuel pump fuse. Check the connectors to fuel pump, eventually read volts at pump and nsure that fuel is circulating
Check air intake and connectors to air intake sensors (MAF sensor), check connection to crank sensor and O2 sensors.

The blown fuses may also have been incidental. If you did not find anything, troubleshooting must proceed as usual, checking distribution, fuel pressure, and then factors that can affect the ignition.

Remember that after a prolonged and failed attempt to crank the vehicle, the cylinders will be flooded and the car will no start (wet plugs- no spark).

Check if there is spark on all cylinders. This can be done removing one by one the spark plugs wires and putting them near to the engine block while someone else try cranking. You will see the spark.
If there is no spark, then you have a coil/distribution problem. test coil by reading volts in and impedance (coil must not be open). I think this engine is not distributorless. Check distributor cap and wires. If you have disconnected spark plug wires after the problem, also ensure that wires are connected in right order.

Once you are sure that there is spark, check fuel delivery and engine control. This part will take longer.

I uploaded here engine control diagrams and other documents that may help.

Regards.

Timing Dpecs for Toyota Supra 87 6 cylinder


1987 non-turbo: 10 deg Before Top Dead Center (BTDC) @700 rpm
1987 Turbo: 10 deg BTDC @650 rpm.

To set the timing, you will need to connect a jumper wire between terminals E1 and TE1 on the diagnostic terminal. This diagnostic terminal is located just aft of the engine compartment fuse box. It is a black plastic box marked "diagnostic" on the cover, which flips open to reveal the terminals inside. There is a diagram on the inside of the cover which explains the terminal positions. On the Turbo model, you need to remove the forward section of the engine cover to gain access to the number one spark plug wire.

It was running before until it sat there for a year or so now it won't start, i check to see if the wires had spark but nothing.


You didn't state what year it is, but check for spark at the coil, or coil pack. If no spark, replace coil. If that doesn't work, then you have more testing to do.

I had the same problem recently but replacing the ignition Coil under the distributor (inside) solved the problem. Also replaced the distributor Cap and rotor at the same time.

87 toyota 22R no spark


To check the Coil, pull the HT lead that comes from the coil to the dissy cap out of the dissy cap and hold close to the engine and with the ignition switch turned on earth the negative side of the coil. If there is no spark then the coil is the likely problem. If there is spark then check that the ignitor is recieving the signal from the pick-up (use an LED tester at the ignitor plug) the tester should blink as you crank the engine over. If the tester doesn't blink then check the output of the pick-up at the plug on the side of the dissy, if still no blink then check the pick-up clearance. If it blinks at the dissy and not at the ignitor the check the wires/plugs for breaks. If it blinks at the ignitor and there is still no spark then the ignitor is the likely fault.
