Top 20 1993 Honda Prelude - Page 7 Questions & Answers

By the sound of it, the ABS is showing failure, this can be due to moisture in the brake fluid, you may need to get the brakes fully bled to remove any moisture. Once the car warms up, the manifold vacuum is kicking in for your brakes to work properly, and this is usually when problems show up. Could also be that there is a vacuum leak somewhere between engine manifold and the brake assist unit. The ABS is simply lighting up to say that something isnt right. If bleeding the brakes doesnt fix it, the next step is to search the rubber vacuum line/s between the power brake unit and the engine intake manifold. If there is no problem there, could simply be an electrical fault that would be a 20 minute job for an auto electrician.

Try to start with a less expensive procedure. In addition to relay I would check the spark plugs, wiring set and distributor cap. Also coolant temperature sensor can be a problem. Try to warm up the endine block of car with dry heat (hair fan or heat gun, but gently). Sometimes it helps. If it works problem is spurk plugs, distributor cap or coolant sensor. Also would be usefull to chek the fuel filter.
But first for cold weather sometimes it worthy to use the injector cleaner/or octane buster and better fuel which evaporates better and less viscouse motor oil. And of course check the battery.
Good Luck

shift solenoids are going bad there are 4 solenoids. they are on top front of transmission and are small round with wires connected. they are in pairs of two.1,2 and 3,4 they control shifting. usually light flashes and the transmission goes into a neutral sounding state when not accelerating

AC COMPRESSOR ON HONDA USE A SINGLE WIRE IT COULD HAVE BEEN UN PLUGED DURING TIMING BELT CHANGE CHECK IT OUT

check your timing??!

I think on those cars you could pull out the ashtray and it was posted in there. if not let glove box lay all the way down and check there. Its been a while since I have done one but I rember it was one of the two

Under hood, passenger side, front engine area, mounted in distributor

pull the spark plug wires out of the number one and number 4 cylinders, then pull the spark plugs out aswell and connect them to the wires they go to. then hold them two the engine block and see if you have a good strong spar/ark.......if not then ur distribortor crack is ur problem, if it does spark take all 4 spark plugs out of the engine and hook up a compression guage and check the compression, if good then check the fuel systesm, fuel pressure regulator/fuel injector/most likely not the fuel pump....if compression is bad then pour a tea spoon of oil in the cylinder that has low compression, do the compression test on that cylinder again, if the initial low reading goes up then its ur piston rings or ur cylinder wall, if it stays the same then its ur valve seals,valve guid,vlave seat carbon build up, check valve train may need a head job

clutch or clutch master cylinder is bad

you should be able to call the honda dealer and give them the VIN# to the car and they should be able to pull it up for you.

try checking the timing...take the valve cover off...remove the rubber cover for your inspection window on the flywheel... line up the white line on your flywheel with the pointer...once your lined up at tdc with the flywheel check your cam sprockets and make sure they are in the right alignment...also take your cap off and look at where your rotor is pointing..making sure it is pointing at #1 cylinder

if you mean next to the ECU then you may be talking about the transmission computer. If you mean under the radio and they are blue and grey, they are for getting check engine light codes. there is no such thing as a brain box so i dont really know what you are talking about.

check your fliuds

I HAVE A 93 ASWELL FOUND ON MINE A GROUNG PROBLEM LOOSE

does this have a factory alarm? aftermarket? check for power out from the switch. starter relay, clutch safety switch, or starter......... have someone get a starter bypass and try to see if it starts. any parts store will tell you if its bad. good luck mark as fixya thanks

fuel pump relay is under dash next to the steering column

i think it could be your Bendix drive. it is the part of the starter that comes out and touches your ring gear. sometimes it becomes worn out and would not catch the teeth of the ring gear right away and it would create this loud grinding noise.

on the other hand, if the Bendix drive is still ok, then there is a probability that your ring gear is the one which has a problem.

good luck,

tnx 4 using fixya, keep me posted,

their is a little carbon fiber rod on a spring in the center of the cap if you loose it it wont run at all

Is the D4 light flashing?

I am having the same problem; I cannot find a 93 Prelude sunroof. But the answer is no you can't use any other year of sunroof on ours. Just about everything else but the roof will fit. Hope this helped.
