Top 20 1990 Honda CRX Questions & Answers

Found this wiring diagram for your generator. I didn't see fusible link? The bat terminal at your generator, should be hot all the time, even with key off. It's a straight shot to positive side of battery. In the diagram, it goes through the 60 amp fuse. If that is the problem, you could leave a pig-tail at the generator and battery, run a new wire, proper size with an inline fuse, bypass the fuse box. As long as that is a dedicated fuse, I don't see why it wouldn't work? Of course, I can't see anything from here. Just my opinion.

the brake lights staying on is a fault in the brake pedal switch,which should be an open circuit when the pedal is up.there is 12v that is passed thru when pushed down.the switch on the reservoir opens and closes with the fluid level. why the dash light stay on leads me to believe that you have a short in the turn signal switch assembly which has light controls on the end .

You can't.

Check the coolant level in the radiator at the cap as it may be the low coolant warning system that is activated as the water runs away from it as you change direction. If it is serious enough the engine light will come on and the CPU will send the engine into limp home mode.

BAD FUEL PRESSURE REGULATOR

I think you need a tune up spark plugs and plug wires distributor cap and distributor rotor

The most likely cause for this to happen on a 1990 Honda CRX is the same as the most likely cause for this to happen on a 2002 Lincoln Navigator.http://www.fixya.com/cars/t12421256-rpm_jumps_up_down_in_rev?eventid=21257965

Spark or enjectin,filters

I believe your car has a full frame windows? If that is correct then are you talking about the rubber the window glass slides up and down in? If so, then you have to remove the inner door panel and might be helpful if you have power windows remove the power window switch from the inner panel and reconnect to wiring harness. Using this technique, there are 2 10mm bolts holding the window glass to the regulator. Position the glass with the 10mm bolts through a couple sight holes, remove the 10mm bolts but hold on to the glass so it doesn't fall in the door and break. install the rubber window channel and reverse procedure.

take it to local honda dealer ship and they will tell you for next to nothing

Firing order is 1-3-4-2...... The no 1 cylinder is located next to timing belt going to the left 1-2-3-4 the fourth cylinder is next to the distributor

Yes the starter from the SOHC motor will work on the DOHC. I have done it many times myself when I had my CRX back in the day. I also had the same question when I first changed mine.

loose wire or corroded connection at the starter or alternator, if not that it cab be ignition switch too

Check fuse or if fuse is good it could be the switch .

HAVE YOU CHECK THE DOOR SWITCHES ?

if its not pumping, its bad.

check your fuel filter first. If plugged replace it

A B16A with no number fallowing it is a JDM engine. If it was a B16A1 for example it is a USDM engine. As for the idle problem its probably a tps sensor and if it idles really low rpms you should up the idle at the trottle body to idle at 800 rpms to be safe, To low of a idle will cause bearings to go out and throw a rod.
Lookj at the valve cover if it is a jdm you will know if it is a SIR or a SIR2, SIR has larger font for the DOHC and smaller font for the VTech The sir2 has larger font Vtech and smaller font DOHC. The SIR2 also has oil jets underside of pistons and rods to help lubricate piston rod conections.

from the battery to the frame then to the Tranny

check the spark then the fuel then the timing
