first: 1988 Civic DX Sedan 5spd

It will crank but it won't start, i'm getting fuel and spark.

I replaced the distributor w/ a known good, no cel's, it will fire once in awhile, the rest of the time it floods out.

I've checked all the vacuum lines and all connectors and everything is good.


i'm new to ef's but know eg's pretty well

 

did it just start doing this or is this after any repairs?

 

i can't believe i forgot that part of it, i guess i'm out of it today.

i changed the headgasket and did an mpfi swap at the same time, the mpfi swap didn't work, it wouldn't rev past 2500rpms
I switched it back to dpfi and used a 91 hatch harness; it still didn't rev up because of the harness and 2 wires switched.
before i realized it was the harness i switched the throttle body for another one i had.

after i switched the throttle body it won't start.

 

i checked all the fuses today and they are all good
both the ground to the head and the thermostat are good.

it started after i switched the throttle bodies, i've switched back to the first one again and it still won't fire.

 

hum? take the cap off and check to see if the rotor screw came off this happen to me and my car wouldnt start it all,make sure the wires are on the dizzy cap right,hum is it throwing any codes if so what are they.

 

no codes, plug wires are on tight and in the right order
rotor is on tight, i'm getting spark to all 4 plugs
getting fuel and compression
timing is correct

 

hum? whats does it do when u try to turn it over

 

it just cranks, that's it
doesn't fire at all.

i can hear the fuel pump when i turn the key on and the injectors are spraying fuel.

 

this might be a long shot, but it could be your ignition switch (where your key is) it did that on my crx and i tore everything apart trying to find the problem, then i stumbled upon the ignition switch replaced it has no problems ever since.

but of course i could be wrong in your situation, good luck

 

WHy on earth would you do an mpfi swap, get it running and have one very small problem to trouble shoot, then swap it all back?

 

i'll check the ignition switch tomorrow

i removed the mpfi because i bought a hatch and i'm going to put all the stuff on that and sell this car.

 

i think i'm going to take another intake manifold i have and put it on.

the whole problem started afer i took the throttle body off so i figure i put a manifold on that the throttle body has not been removed and that may fix it.

 

take a look at the crank sensor and Cyl sensor Signal, if one of those aint working, buy a new distributor. The distributor wont fire any spark since he doesnt know where the firing sequence beggins ...

 

i've tried another distributor off a working engine and still no dice

thanks for the help though, much appreciated

 

i put the original manifold on and still didn't start
new plugs and it fires now and wants to start, battery is almost dead so i'm gonna jump it and see if that helps at all.

 

dont quote me, but when u put the tb on did u happen to **** with the idler??? maybe ur idoling (damn i cant spell) too low to let it start.

You've been quoted.

Seriously though, have you checked the ignition switch yet?

 

i looked at the ignistion switch and all the wires look to be secure and none are heating up, how else should i check it?

 

did you switch tps when you changed throttle body?

 

switch TPS? when i had the mpfi on i switched the wires yes
but i used a stock uncut harness when i switched back to dpfi and didn't mess with the tps at all

 

dude it sounds like u got one hell of a wiring prob. good luck trying to fix that lol

 

wiring isn't a problem
i took the old engine harness out that hacked apart for mpfi and switched it w/ my friends stock harness(88 std)
i moved the pins back on the ecu and put that back to stock.

i'm gonna try it tomorrow, i'm hoping that i just flooded it out today and that's why it wouldn't start all the way.
good news is i have 185psi compression across the board which is pretty damn good for having 222k miles on it

you are using a 91 harness in a 91 car, correct? cause the pinouts change from year to year if im remembering correctly...i dunno its late.

also, yea try charging the battery.

i was doin the same thing, battery was at 11.8 volts. charged it to about 12.6 and it worked fine.

 

i did have the 91 harness in the 88 civic and found out afterwards that they are different, so i know have an 88 harness in the 88 car.
