Question about 1990 Toyota Xtracab

2 Answers

I have a 1990 corolla sedan with 4Afe motor. I have a no spark issue. Yes the rotor is spinning, it's not a broken timing belt. I'm on my third ECU and two different distributor assemblies. Also a new ignition switch. Checked the wiring harness for bad wires. I noticed that the main engine relay pulls in when key is turned on, but does not release when key is tuned off. Is this normal. Also I have no "check engine light" with key on or during cranking. Does this mean i have no power going to the computer. Any help would be useful as I really need this car as soon as possible.

    There is no crankshaft sensor on this car. Does the check engine light being on with key on car not running signify power to the ecu.

Good Evening, since you have replaced the usual toyota subjects which are the computer and the distributor (normal causes), the next possibility is the crankshaft position sensor. We got one of these a while back and the local new car dealer where it was traded in at said it was the fuel pump, replaced the usual suspects, then ended up ohming out the crankshaft position sensor and it was bad. I hope this helps, and if you have any more questions please feel free to ask.

    I will have to pull up the power diagram for you in the morning, I did run through this afternoon and notice there was not a crankshaft sensor, and I apologize I was in error. I will go through it more in the morning and get back to you unless you find a solution before then,

Have you checked the fuses? If you have no engine lights, then you have no power to the dash. Instead of replacing things like the ignition switch, you need to use a test light to see if there is voltage in and voltage out. You also did not mention checking the coil. The ECU, distributer, etc., can be checked for free at a place like Autozone.
Don't know about the relay. Where is it located? I would think the only relays would be for the fuel pump, headlights, AC, fan, and flashers.

    If you get really, really desperate, (as I have on occasion), you can get an engine harness at a junkyard for a few dollars; and then you can rotate the distributor by taking it out and attaching to an electric drill with some rubber tubing and hose clamps. You can simulate the entire circuit on a bench.

    The big thing you want to check with a test light is power getting to the coil. All it takes is a burned out condenser to prevent spark. Coils often also have ballast resistors you need to check with an ohmmeter. A multi meter is $3 at a place like Harbor Freight.

Replace the coil and still not getting fire what else can it be on 91 geo prism

91 is a corolla with 4AFE TOY ENGINE,! and is same Car.
no spark in all 5 places 4 spark plugs and COIL Center tower?
I'll assume the coil is dead. no high voltage spark at center.
lots ,ill list them all
  1. fuses, check all fuses in both boxes.
  2. is CEL lamp glowing key on, if not ECU has no power is is dead.
  3. insert diagostic jumper? crank for 5 seconds, release key is CEL flashing DTC errors> if yes, BINGO ! CMP fails?
  4. is the cam spinning (belt snapped) if the cam is dead there will be no spark. so do the belt service per FSM rules.
  5. is the DTC ERROR, FOR SPARK, That means the ignitor is dead. so.... use the jumpers

the Jumper
just short Te1 and e1 with a paper clip
google toyota jumper TE1
and read.

this page cover all years, and DLC movements
musical DLCs. if you were.

answer if all 5 places, dead. this speaks VOLUMES
after all if cam slips , rotor is off an sparks go dead but coil
not deadl.
but if belt SNAPS all 5 go dead because CMP goes dead.
this how all efi works.
but on very early engines, the distributor is more stand alone.

I have a 95 Geo Metro 4 cylinder automatic it wont start it turns over but it won't start and I have no spark could it be the timing would that do it if the timing is off?

ok penny , you have a G16 engine
and no spark, that mean at all 4 spark plugs and the coil?
5 places, ?
if the coil makes spark, but not at plugs. that means
the cam belt slipped, did you forget to do the 60,000 mile service?
turn crank by hand does distributor rotor spin?
No , belt snap.
same check , look and oil filler hole, does the cam spin? , cranked hand turned.?
no ?, belt is gone. CAM TIMING BELT.

yes turns, then check compression (a tool) at wide open throttle.
if compression is over 150 PSI, then ok
if way low, like 80 the cam belt is slipped,
all easy tests, all less that 20 bucks in tools.

FIRST check fuses.
then check that the Check engine light glows key on
if not , there is no DC electrical power to the ECU (injection system or spark or both. the ECU cuts fuel for no spark, (hint))
there are 3 fuses, that must be good, to start any suzuki this year.
2 are critical.

if all this is klingon ?
get it serviced.

1990 nisan n13 motor 1.6, has no spark to coil i drove car to train station, when i got back the car would not start, replaced coil, distributor, ecu box, all fuesible links, plugs & plug leads, fuel...

Your car has both a crank and cam position sensor. First start with your crankshaft position sensor. It is located by the harmonic balancer on the front of the motor.

I have a 1990 toyota with the v6 it turns over but no spark and no gas

-Does it have a distributor...?
-If so. Remove the distributor cap cover (Only the cap Cover) and ask a helper to help you crank the car for 3-4 seconds.
Q: Does the distributor turn (Spin) ?
A: Yes. Then check head relay and fuses.
A: No. Timing chain or belt is broken.

Lost fire from distribitor

96 1.6l ( there are 3 fuses. FI, COIL and dome) fix those first.

the coil is inside, did you check the output of the coil
for spark cap off dizzy? is that no spark.?
is the tachometer dead cranking.? if yes no tacho, then there
is no coil drive. from ECU.
the Dizzy is 100% controlled by the ECU.
the ECU has an OBD2 scan port above the right knee,
plug in any scan tool ($50 hand held)
crank motor over , see if RPM shows up, if not then CMP is dead.
read the scan tools DTC codes, is the ECU complaining of bad sensors. ( this is #2 after fuses) do not work on cars with no scan tool, this is a waste of time, and money.
no start or better no spark. if really true.
sometimes mech think there is no spark but the cam belt slipped
or the cam is not even spinning, dizzy rotor dead, dont turn.
or the coil really does have spark and dizzy timing is way off.
Dizzy clamp bolt, loose? bad spark wires, connected backwards.

all here

My car will not start, it turns over but wont ignite. i have changed the plugs, wires, distributor cap, rotor, and ignition coil. i am at a loss on what else could be causing this.

fuses, relay, corrosion at wire connections, ignition switch, pick up coil, ignition control module. Is the distributor rotor turning when you crank the engine? I ask this because a broken timing belt would cause a no start condition.

No spark from coil

okay the first thing is to make sure the timing belt did not break, remove the distrubutor cap, have someone crank the engine as you watch the dist rotor, see if it spins. if it spins then belt didnt break, the next thing is the coil, this coil also contain the ignition module, this is a common problem with a no spark problem on vw. if rotor spins then my next thing would be to replace that coil/module. heres a picture of it, hope this helps.5f2a14b.jpg

Rotor in the Distributor does not turn

probably a broken timing belt. $500 repair. Connects camshaft to crankshaft and distributor runs off camshaft.

Chrank but no spark

If the chain broke at highway speed then you have probably bent valves too. Does the motor spin fast? If it sounds different cranking then it may have bent valves. You can do a compression test to find out for sure. Good Luck
