87 prelude, cranks fine, no spark and little/ no fuel, hope its not like my earlier civic which kills fuel pump and is located in the cluster, a small chip, screwed into it, called a speed sensor! Found like 5 in a row bad at the wreckers.Honda parts people could not find a speed sensor separately but had to buy the whole cluster , something like 300 OK any ideas on my prelude would be appreciated.

My car wont start battery is ok got feul and a spark, its cranking over but dosent seem to be getting fuel


Could be a million things still. Your fuel pump is dead, theres a clog in the lines, fuel filter is done for. On some fords, there is a kill switch located somewhere for the fuel pump. If you're not smelling gas (flooded cylinder), I'd look at the fuel pump fuse or that kill switch, if those are fine maybe replace the fuel pump.

My car cut off while i was driving


Civics are known to fail in two areas the main relay or ignitor.

1-First turn your Switch to ONII and check if your check engine light come on for two seconds and turn off, at the same time you need to hear the fuel pump priming. If you not hear the fuel pump the main relay is the culprit, if the CEL stay on retrieve the codes and start from there. The OEM MR is $60-65, eBay have the knock off for around $25.00

2- If the first part test fine, buy a spark tester or put a plug in the wire one. Have a friend crank the car and look for spark. If spark not present you have a bad ignitor. This ignitor is a little pricy OEM, The eBay units run for $25.00 but this are knock offs.

Hope this help

I have a 1992 Honda civic lx with a 1.5 four cylinder, and Ive replaced the ignition switch the fuel pump relay and the fueled pump itself however, the fuel pump still doesn't prime when I turn the key...


no start , crank perfectly
so , got spark?
the ECU has programming (ROM) and in fact kills all fueling with no spark , (even if it thinks there is no spark, even if spark is ok)
all ECU use a way to read back spark quality, (ALL){LAWS}
how honda does it in code, i don't know , see C R O M E forum)
turn the key over means nothing to me.?? sorry, it doent/
try saying what postion? cranking? or just keyon.
now some more EFI rules.
The EFI (some) do not activate the pump relay until cranking.
some do just key on for 3 seconds, read the FSM, its free.
need a link to the free manual? read the ECU logic on that.?
and prime has a special meaning, it means purge air,
its not for fuel. some system send a fast prime pulse. to clear air from the pressure lines, this plus does not inject.
that is how EFI works,

the flow
1: key on, ECU sends prime pulse, (air purge)
2: some ecu, run pump for 3 seconds, and pressure hits 35psi? RTM.
3: all ecu activate pump cranking and running.
4: now check pressure. !" 36 psi FSM stated spec"
5: now crank, if the ECU sees no spark errors, it injects
6: if the ECU sees WOT. it stops injection to clear a flood, cranking.
those rules cover most ECU made.

honda this year has a special feature called,
Fuel Cut-Off Control'
if this messes up, it i can cut fuel
does this help?
even better is this site, (has all the facts..)

My 1991 lexus will not start when the ignition is turn with the key. The ingine constantly turns over without starting and preceeds to kill my batterie.


Well if it is cranking you need to see if you are getting spark and fuel.....Try turning the ignition on without cranking the motor....You should hear your fuel pump making a whirring sound for about 3 sec.and then shut off...If no sound from pump (which is located in the fuel tank) check the fuel pump fuse If fuse is good check fuel pump relay...If all checks out ok with fuel pump take into consideration when the fuel filter was changed last....I dont recommend adding fuel injection cleaner to your tank without first changing fuel filter...additive is designed to break up debris thus breaking up all trapped particles in filter sending debris through your injectors.... To check for spark pull the #1 spark plug wire and place it on an angle on tip of plug (allowing you to see if spark is present) have an assistant crank engine while you look for spark..... Do not hold spark plug wire in your hand while engine is cranked.... I hope this has helped you

1997 dodge ram won't start. My fuel pump does not run and coil won't spark. Iv'e checked fuses and relays and they look fine. Could a bad fuel pump cause the asd to kill power to the coil?


First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.

Sounds like the fuel pump may be going out. I'd have it checked.

Starting problem with honda civic


Next things to check are fuel and spark, remove a spark plug and with the wire attached crank the motor, if you see spark in the plug then it's not a spark issue and probably a fuel problem. If there is no spark could be bad plugs or wires, or distrubitor cap. To check fuel remove injector cover and crank motor, if there is no fuel coming out then check fuel filter, fuel pump.

Good Luck
