check tire pressure and alignement.

Two common issues on these old Accords that no one ever mentions. First, replace the main relay (It's located in a tight spot under the driver's side of the dash behind the silver cruise control module). It's notorious for causing fuel starvation problems because over time the soldering on the connections on the relay crack when it's hot, and will make contact when it's cold. You can find videos on Youtube on where it's located and how to replace it. Just search "1990 Honda Accord main relay". Second, you don't need a scanner to diagnose an OBD1 system. There is a self diagnostic plug located on the passenger side near the kick panel below the dash. Google "1990 Honda Accord Self Diagnostic CEL Lights" to find out how to do it and get CEL codes and descriptions.

I would look to see if there is a fuse link or fuse blown

Could be as simple as a burnt fuse under the hood, near passenger side. I believe it's a 15a or 20. Does your radio work at all. I think they run together. That's what happen to mine. Good luck

I would start by checking the fuse. You will have to look up the location for that model because I am not sure. Next, I would check power at the fan connector. If you have 12 volts (or close to that) then the fan motor is most likely bad. If no voltage and the fuse is good, you need to troubleshoot the fan switch.

Doesnt really matter. This is not important. Make them snug

I do not think so since I believe that there is no smog pump. On mine (LX) one belt goes to the power steering (which can be removed if you want to steer without power assist) and the other goes to the water pump and alternator. When I bought my car it was this way, and I have passed several emission tests as is.

spark plugs, coils, need to be replaced

REMOVE AND CLEAN THE TROTTLE BODY

Just checked a 1990 Accord LX. It is right above the oil filter. It is visible from the top of the car, but it looks like you would want to remove the oil filter and access it from the bottom because the intake manifold is in the way going from the top.

there are many gears. are all gears dead, forward and reverse even at 3000 engine RPM? is the transmission slipping if RPM gets stuck at say 1500 to 2000 that means the brakes are frozen in ICE.

Do you have normal compression, fuel pressure, and spark ?

Have you looked into your crankshaft sensor

I have a 91 Accord. The speedometer started going wild, 30 mph. 75 mph and I was at a stop finally quit working and the S light came on. I finally changed the speedo sensor and the S light went off...Check engine light was also on, read on a forum that the speedo sensor does more than control your speedometer, maybe that your trans is not getting the info it needs to shift.....

simple answer, turn on the fan to the fresh air setting and get some air in there. since that is so obvious, you might already be doing that. another possibility is if your heater core has a small leak then as you are drawing air through it the leaked coolant/water is evaporating into the incoming air and is helping your windows fog up.

if u turn the ac on it wont fog up at all put it on defrost

well do it.? need the steps? is that it? alldata.com what i do is look at the switch and adjust it for full compession at pedal up. on some cars, there is a jam nut there. and it falls off and the switch unscrews and changes daily. only looking and touching works and using any Ohm meter to test the switch and for consistancy. all that is hands one.
