Question about 1996 Honda Prelude

1 Answer

I got a 96 honda prelude sr-v h22a1 which i have swapped out for a 98 h22z1 motor. However i started the car with the new engine with a broken knock sensor went into limp mode bla bla bla. car wont start now. Oil light came on car died out. Now the car sends spark through the coil but not through the distributor. do i need a new ecu that customized for this set up or what are my other options? i was told that the p28 chipped and tuned will work with the od2-ob1 harness. Any help would be great

I strongly suggest you initially concentrate on the basics. First ensure the engine is ok in all respects...

I seem to remember Honda used to use the oil light as part of the fuel safety system - if the oil light came on the fuel pump would stop. That was a long time ago but well worth looking into. You did say the oil light came on and then the engine stopped - it isn't surprising the engine stopped but it is of fundamental importance to discover why the oil light came on.

If the coil is producing sparks but the distributor is not redirecting those sparks to each cylinder there is clearly a fault inside the distributor that should be rectified. Similarly that broken knock sensor should be replaced and the fault codes in the brain recorded and erased before continuing.

Diagnosing stuff and verifying each diagnosis is a process that must be worked through systematically - you have a long, long way to go before you need to be considering a new ECU.

SOURCE: bottom radiator hose cold. upper radiator bulging.

The fan won't come on because the thermoswitch is in the bottom of the radiator, without coolant flow the switch never gets hot. Just because a part is new doesn't mean it is good, is the thermostat an aftermarket part ? I would take out the thermostat (leave the gasket) and see if the bottom hose gets warm. If the bottom hose does not get warm, you may have a blockage or bad water pump

Could be the ignition coil or ignition module. Also check the ignition fuse.

SOURCE: 1991 honda accord get gas,spark,timing rihgt and

Is there any reason that you have not checked the valve lash on the engine?It's really quite simple and if you have misadjusted intake valves the car will never start. Not to mention with while adjusting valves you will have to double check crank and cam timing twice (once at cylinder 1 adjust and once at cylinder 4 adjust)at the same time you will also be abble to watch dist.rotation and again be able to see that the dist rotor is in the correct firing position in junction with cam timing.ANYTIME a honda or acura has belt replaced you will check valve clearances,it changes with different belt tention on end of camshaft. when distributor was replaced was ignitor unit replaced,and coil (both inside dist. housing)replaced at this time?Hondas and Acuras both are notorious for failed ignitors and coils.(intermitantly even)this can result intermitant spark(either of the two) or weak spark when failing coil is problem. you may have spark but how hot is it?And last but not least ,most affordable but extremely coomon not ever replace spark plugs on honda with anything but NGK spark plugs,if you use bosch ,bosch platinums you "WILL" see running problems and or no start!!!!!splitfire plugs will be destroyed within weeks in a Honda!And use nothing but a Honda Distributor Rotor. T.E.C is manufacturer of Honda cap & Rotors.You may be thinking to yourself how silly and anal i am about those things but i can say i have seen hundreds of civics,integras,preludes,with no starts,poor performance,etc,with customers"just replaced plugs,cap and rotor,they should be good they were expensive bill at checker said they were the best".hundreds of dollars later and driving out with NGK plugs and honda cap and rotor,lesson learned

Broken lifter arm 96 honda prelude?

Interesting question. If you think a lifter arm, which I presume is also called a rocker arm, is broken, remove the valve cover and find it. All the rocker arms are visible, and should be easy to see.

I am getting a used engine because my h23a1 blew, I was wondering if there are any components I should replace during this process.

ok so hear me out, DO NOT! i repeat, NOT buy a h23... honda stopped making this motor completely in 97 these are the worst motors in the world! i know, your rod bearing blew, I KNOW! ive donr 30 of them. Buy an h22 swap for your car... or just the motor.. everything bolts up the same...then if you wan the performance wire up the vtec... 92-96 preludes came with the option of an h22... if you could find one out of your year model and not out of a 97 up, that would be best so all your vaccum lines are the same... youll have to use the h22 harness and ecu.. if its standard, you need to use a standard h22 harness, if its automatic, use an auto harness
hope this helps

I have a 1998 honda prelude h22 vetc automatic with 178K the motor runs fine but the transmisson when i put it in reverse i knocks the it will do fine threw first kinda slip in second and then not go into...

Definitely change the transmission oil - could be some rubbish in there stopping the actuators working correctly. If that doesn't work, could be time for rebuild with new friction material in the clutches.

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.

Timing belt is hard to find

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.
