Question about 1993 Honda Prelude

1 Answer

Camshaft position sensor

Hello. I have a 93 Honda Prelude DOHC VTEC. I recently did a simple tune up on it like always. When I went to start the car back up there was a lot of hesitation and misfire then it died. It was a hard start right after that and with the same results. I tried to start it again and now the engine just rotates with no start. I have replaced the distributor with new cap and rotor. There are new wires and plugs. I have no spark at the plugs. I have fuel getting to the engine. I have been told that my camshaft position sensor has gone out. Could this be true? If so how would I fix it?

My wild useless guess (on site it be 5min work)
is you failed to replace the HV spark wires 1 by one.
losing the timing order.?
sure, like 1million posts world wide, all say CMP/CKP are bad, few are.(most posters love to guess. and spend your cash)

it ran before, the belt went bad. right?
what tune up, just spark? only and filters.
or the timing belt. (dont skip that or you will bend the valves in the cylinder head)
no spark, at all 4 plugs.
you didnt remove the distributor?
my guess is this old post you found it.
the ECU in your car is old and can in fact report via lights , code lamps CMP or CKP bad. did you look for that?
its documented well and free at all honda forums. (not here)

here are the codes and tests for old OBD0 and OBD1 hondas
code 4? code 15, code 8/9? all kill spark or just fuel. see OBD1 link at bottom of page.

SOURCE: 93 honda prelude dohc vtec engine will not can be push started

Sounds like you accidently pulled the thin wire from you starter motor. Look at the connections at the end of the solenoid, mounted on starter motor.The thick red wire is Battery + next to that connection is a smaller male push- on terminal, locate loose wire (thin) in the same area and reconnect to male push-on terminal on solenoid or check if earth cable between body/battery to engine wasnt removed in the process.Also some vehicles you have to engage the clutch before starting, check for a switch located on clutch pedal where master cylinder connects to clutch pedal (Is clutch switch mounted and wiring connected?)

you may have a faulty crank position sensor shutting the spark off. this will throw a code into the computer though my suggestion would be to have the ecm read for codes.

SOURCE: 1996 Honda Accord Rough Idle Even After tune up

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

Misfires


there are 50 causes of misfire. (and flooding)
50
what we do is, conduct simple tests to find what is going on.
but first do that missed , 60,000 mile tune up, it might fix the problem
in FACT , tuneups are 100% designed to what, stop misfire.

my wild guess is it flooding.
are the spark tips (all) soaking in fuel , stalled?

thats one test, and is free, for any show with basic tools.

if you need more help tell engines option and country.

The sixth generation featured updated styling although less radical than previous redesigns. Suspension and engine options were available along with their first Natural Gas Powered Civic, the GX. From 1996-2000 the Civic was sold under the CX, DX, EX, EXR, HX, LX, and for Canada, SE, and Si trims; all base models were made with 1.6L engines. The EX-CX are all SOHC (Honda D engine). The CX, DX, and LX all have D16y7 non-VTEC engines; whereas the EX has a D16y8 VTEC, and the HX has D16y5 VTEC-E. The USDM Si and Canadian SiR came with a DOHC (B16A2 VTEC). The first civic SI coupe EM1 was introduced in 1999 until 2000. Europe saw a DOHC 1.6 VTI hatch and sedan and a DOHC 1.8VTI engine was available for the Domani related five-door liftback and estate..

I have a 93 honda prelude vtec 2.2l drove and parked, will not start, just cranks over. replaced coil, starter, main relay switch, ignitor, plugs, getting fuel but will not start


Do you have fuel pressure? Is 12 volts available to the injectors with the key turned to run (use a 12 volt test light to check this). Have you checked the combination relay located behind the glove box on most Honda models??

I just bought a 93 prelude with the 2.3l vtec the guy said that the engine was just rebuilt it has the dohc engine the valves are clicking he told me to run the car so the valves will seat??? then he...


not really. The engine uses hydraulic lash adjusters, so there is nothing for him to adjust. If the engine has been run at all, the valves should be seated. If not, maybe the guides were over-knurled. Can't really tell why they are clicking. Can he provide specifics of what was done to the engine? Does it have new lash adjusters? Were the guides knurled or what was done with the guides? What was done to the valves? Are the springs new? Are the camshafts new? etc. etc.

Possible speed sensor. I know the speed sensors are a problem with hondas. A new speed sensor is about $200 and can be easily replaced. It bolts to the top of the transmission on the firewall side. Do NOT buy an e-bay one. They are only about $30 but are junk
