Top 20 Hyundai Motor 1991 Scoupe Questions & Answers

http://ricksfreeautorepairadvice.com/check-engine-light-on-part-i/

You stated the 'CHECK ENGINE' light came 'ON'!... what/which DTC'S (Diagnostic Trouble Codes) OBDI were retrieved? In 1991, OBDI (1) was used. You could retrieve codes by either turning the ignition switch on/off two or three time within 3 seconds and the light would flash for each number (this way you could determine which system was affected). The POSSIBLE CAUSES are many:

Crank Position Sensor
Ignition Coils/Wires
Water/contaminated fuel
Electrical (Relay(s), fuse(s), Poor ground connections, failed ECU (Engine Control Unit), etc.

Are you getting a SPARK to the plugs?... if so, check fuel pump pressure
If you're not getting a spark to the plugs or not getting a fuel injector PULSE, then the crank position sensor MIGHT BE the problem.... NOT SURE!

Too many POSSIBLE or PROBABLE causes.

In order for an engine to RUN, it needs these things:

1. Air flow (intake AND exhaust)
2. Fuel (proper fuel to air mixture)
3. Compression (140 to 2?? psi)
4. Proper Timing (not too advanced/retarded)
5. Ignition (sufficient and at the correct/right time)

Now, after listing these 5 things, without CHECKING each one, your guess is a good as mine.

thats a feature on a car so you dont over rev the engine

There is a kit at walmart - -it is an install kit with 134A freon - purchase that kit and add one can until the AC blows real cold - -cheapest way to go.

replace the started it has a dead short in it

If you have a national auto parts chain store near you (autozone, advanced auto parts, pep boys,etc etc) Have them hook up an obd2 tester to your car and see if any codes come up(they do this for free!!!). If nothing then I would check the ignition switch module inside the steering column, it may be energizing the starter motor but not sending a signal to the ecu that the car is trying to be started.

sorry i don't have books that far back but a 1993 scoupe had the filter located next to the windshield wiper motor. held on by a strap and 1 bolt there is a gas line on the top and bottom of the filter,with a banjo fitting on the ends.hopes this helps.let me know.

Follw the top radiator hose to were it ends, there will be a hosing with two bolts, undo bolts, lift of housing to reveal thermostat, use new gasket when relacing

HI
the (ECT)coolant temp sensor have two wire and you can test it by (AVO meter) the two wire :-
the 1st is ground from ECM
the 2nd is have 5 volt whine disconnect the connector
of (ECT) and less then whine connected the (ECT)
the (ECT)was electronic thermo resistor
the one wire sensor work to coolant temp gage in dashboard

the (VSS) locate in trans axle it was electromagnetic sensor send signal to determine the distance in (KILOMETER)

with my best wishes

sounds like it could be a fuel problem (Starving for fuel) need more info though

If you hear a click under the hood from the starter the starter solenoid but starter is defective and you should rebuild it. If that is not the case I would replace the ignition starter switch, this is the electrical switch the key cylinder actuates to turn on the electrical system and engage the starter.

Same old story mate if you only pay peanuts then you only get monkeys to work for you ...

check ignition coil.

it sounds electrical sorry cant be more help
