ive searched online and they seem to be related, and came to the conclusion that you need a new o2 sensor. hope this helps, goodluck.

1992 honda no spark


1 one spark plug or all 4? (key fact one missing)



insert honda OBD1 diagnostic jumper (or as FSM directs)

engage Diag mode.

then crank engine for 5 seconds.

then release key,

does the ECU flash out codes for a failure.,, BINGO

all cars work like this 1987 to now, USA>

what engine, of the many?







fsm quotes (and vast on line data same on all honda\'s)

there are more online facts on honda\'s than any car.

they race them and have hacked them to infinite levels.

now thequote



On 1990-95 Accord (except V-6) and 1992-95 Prelude, the codes are read from the check engine light after the two-wire service connector has been jumpered. On Accords, the service connector is under the dash on the passenger side. On Preludes, it is located behind the center console. Codes 1 through 9 are indicated by a series of short flashes; two-digit codes use a long flash for the first digit followed by the appropriate number of short flashes. For example, Code 14 would be indicated by 1 long flash followed by 4 short flashes. Codes are separated by a pause between displays. Multiple codes are transmitted in an alternating pattern. For example, a code 3 and 14 would be displayed as 3 short flashes (for Code 3) followed by the separator pause, then 1 long flash and 4 short flashes (for Code 14).



my comment, code 4 or 8 tells you , CKP or CMP sensors are dead.

in gringo that is "crank or cam sensors dead)

the ECU can report even , 1 in 10 pulses missing.

its very very , accurate in this report.

crank

release key

wait a minute to see if the ECU sets DTC errors.

do not turn off the key,or it erases them. wait, for 5min.

How to turn the rely back on to the fuel pump


as always check all fuses FIRST (electrics issues, EFI is that.)

the Puter magic is mindboggling, but..
why not post the symptoms, ????????
is it dead fuel pump or the more accurate, low or no fuel pressure?

All ECU/PCM (EFI ) all cut the pump for many reasons.
PCM is PGM-FI , in honda speak. PCM is modern term.
first really is fuse checks. !!!
1: no spark. (did you pull the CEL DTC blink codes to see if the ECU
is unhappy?
2: many cars (you must crank to run the pump) so looking not cranking for 12v at the pump , you fail and is normal.
(2 man rule one to crank, one to listen or check voltage at pump
or pump pressure at rail or filter) (a new filter is a good ploy now)

the fsm is here, and covers this, read the FSM
some pages are missing,,, so get real FSM
or go to alldata.com

this page is valid.

I like the (above) is cam dead?, line.... funny that.
(gather evidence, fuses good, cam spins (watch it) no DTC stored.
then check for spark no spark work spark now ,not fuel.
with a dead cam there is no CMP , no CMP the ECU pukes
codes for CMP Dead.
this is an interference engine so i'd bet that belt is fresh, huh?
ever 60k? per the opr; guide.

watch for codes, 4,8,9,15,16 (OBD2 DTC codes)
code 9 is dead cam. dead spark and all fuel is cut. for ever.
TDC&crank sensor, must work and not show DTC codes.

1994 legend speedometer works once in a while


92 or 94?
is fuse 22 loose?
did the CEL lamp in dash glow at this FAILURE event
or S, D or D4 auto tranny lamps flash? BINGO,

did you look for ECU/PCM errors first.? that be first .
is the odometer dead? too, at same time?
on this car the VSS module (veh.speed sensor)
sends the speed data to 6 other modules. the speedometer is 1.
so of the other 5 are dead, its the VSS dead, if not its a bad speedometer.
on of those modules is the PCM, that runs the EFI engine.
so scan it, on this old car, you insert the diagnostic jumper
(service check conn.)
and read the flash codes from the CEL lamp in the dash.
this will show 17 error, VSS bad. if bad (its bad or bad conn)
easy huh?

log in to alldata.com and read the how to read OBD1 codes
it will be something like this. (photos missing)
When a fault is noted, the ECU (otherwise known as the ECM) stores an identifying code and illuminates the CHECK ENGINE light. The code will remain in memory until cleared; the dashboard warning lamp may not illuminate during the next ignition cycle if the fault is no longer present. Not all faults noted by the ECU will trigger the dashboard warning lamp although the fault code will be set in memory. For this reason, troubleshooting should be based on the presence of stored codes, not the illumination of the warning lamp while the car is operating.
All models are equipped with a service connector in side the cabin of the vehicle. If the service connector is jumped, the CHECK ENGINE lamp will display the stored codes in the same fashion.
The 2-pin service connector is located under the extreme right dashboard on Integra, Legend & 2.5TL; on Vigor models, it is found behind the right side of the center console well under the dashboard.
Codes 1-9 are indicated by a series of short flashes; two-digit codes use a number of long flashes for the first digit followed by the appropriate number of short flashes. For example, Code 43 would be indicated by 4 long flashes followed by 3 short flashes. Codes are separated by a longer pause between transaxles. The position of the codes during output can be helpful in diagnostic work. Multiple codes transmitted in isolated order indicate unique occurrences; a display of showing 1-1-1-pause-9-9-9 indicates two problems or problems occurring at different times. An alternating display, such as 1-9-1-9-1, indicates simultaneous occurrences of the faults.
When counting flashes to determine codes, a code not valid for the vehicle may be found. In this case, first recount the flashes to confirm an accurate count. If necessary, turn the ignition switch OFF, then recycle the system and begin the count again. If the Code is not valid for the vehicle, the ECU must be replaced.
and this warning
On vehicles with automatic transaxles, the S, D or D4 lamp may flash with the CHECK ENGINE lamp if certain codes are stored. For Legend this may occur with Codes 6, 7 or 17. On Vigor and Integra it may occur with codes 6, 7 or 13. In addition, the TCS lamp on NSX may flash with codes 3, 5, 6,13,15,16,17, 35 or 36. In all cases, proceed with the diagnosis based on the engine code shown. After repairs, recheck the lamp. If the additional warning lamp is still lit, proceed with diagnosis for that system.

  1. Use a jumper wire to connect the two terminals of the service connector together.
  2. Turn the ignition switch ON ; the check engine light will display any stored codes by rhythmic flashing.

In the event that a code is encountered which is not on the chart, re-count the number of flashes. If the code is truly wrong, it will be necessary to swap the ECU for a known-good unit and recheck. Since this can be expensive, you may wish to bring the car to a reputable repair facility if no other cause of the failure can be found. This may save you the expense of purchasing an unnecessary part.
  1. If no codes are displayed but a driveablity problem exits, testing of the system individual components is necessary to find the problem. If codes are displayed, follow the appropriate troubleshooting chart in this section.

TROUBLE CODES System Diagnosis READING CODES When the "Check Engine'' warning light on the dashboard comes on and stays on, it indicates a problem in the fuel injection/emissions system. Check the ECU for fault codes. On certain models, some codes will not trigger the check engine light; if driveability has suffered, check for stored fault codes. The most common error when using fault codes is to assume the indicated component has failed rather than checking the entire circuit. The presence of a trouble code means simply that the electrical circuit for the named component is not functioning properly. For example, a code for the oxygen sensor circuit does not automatically mean the oxygen sensor has failed. A wire terminal may simply be loose or corroded at the connector. When using diagnostic or fault codes, always remember that the entire circuit including the component must be checked carefully. On 1990-95 Accord (except V-6) and 1992-95 Prelude, the codes are read from the check engine light after the two-wire service connector has been jumpered. On Accords, the service connector is under the dash on the passenger side. On Preludes, it is located behind the center console. Codes 1 through 9 are indicated by a series of short flashes; two-digit codes use a long flash for the first digit followed by the appropriate number of short flashes. For example, Code 14 would be indicated by 1 long flash followed by 4 short flashes. Codes are separated by a pause between displays. Multiple codes are transmitted in an alternating pattern. For example, a code 3 and 14 would be displayed as 3 short flashes (for Code 3) followed by the separator pause, then 1 long flash and 4 short flashes (for Code 14).

The first thing I would do is check the Transmission Control Module (TCM) for stored codes. To call up codes, cycle ignition switch on, off, on, off and on within 5 seconds. Stored codes will be indicated by flashes of the check engine lamp. The codes will be indicated as two digit numbers, with a four second pause between codes. An example of a code scan is as follows:
  • Power Loss/Check Engine Lamp illuminated for approximately 2 to 3 seconds as a bulb check, then turns off.
  • Lamp flashes 2 times, pauses, then flashes 6 times.
  • Lamp pauses for approximately 4 seconds.
  • Lamp flashes 3 times, pauses, then flashes 1 time.
This would indicate that code 26 and 31 are stored. The lamp will continue to flash until all stored codes have been displayed.
If we are lucky we'll get some codes to work with. This will show you any transmission codes.

I found that a code 31 on a 94 Voyager indicates an evaporative emissions problem, but I'm not sure whether that code applies to your car as well. Have the ECU scanned at AutoZone and see what comes up. They'll do it for free and will give you the codes. Then you can post them up and we'll see what we can do about them.
