i have a '91 civic hatch. It's the base model with DPFI & only 4 gears. I have no modifications on this vehicle. It has been running great even with 297k on it. But then, the other morning it wouldn't start. Nothing happened at all when i turned the key, so I thought it was the battery, so i jumped it and checked the voltage.... 12. still nothing.

I then replaced the starter with one from a '92 DX (i had it laying around and it fit). The crank would then at least turn, but it sounded like no ignition. I checked the plugs.... and they were saturated ( i obviously flooded the engine). I took the cap off and noticed that my coil was melted/fried. So, i picked up a new cap, rotor, coil & plugs. I put everything together & the car still wouldn't start. I checked the plugs for spark & they are working.

When I try to start the car, it sounds as if there is no combustion at all...... I am getting spark, & when i take out the plugs they have gas on them, so i'm sure that i'm getting fuel.
WTF?.... any suggestions?

 

so you have fuel and spark now.
you double check the wires to the dizzy?

 

i unplugged the wires from the old cap 1 at a time and immediately plugged them in the same order on the new cap. i'm very sure they are in the correct firing order. i'll definitely double-check tonight.

 

check the ignition control module

 

i definitely looked into it the problem a lot further last night.
-checked the plug order... fine.
-checked ignition timing... fine.
-checked the ignition control module... fine.

i'm definitely getting spark.

moving on to fuel...
checked the injectors (only 2 of them) for a pulse... yes.
loosened fuel line to check for fuel pressure... none!

the gas guage reads full.... took off the back seat.... checked voltage to fuel pump... only reading 10v. checked voltage when starting car.... still only 10v. i couldn't hear the fuel pump turn on either. i am pretty sure i have isolated the problem to being the fuel pump.

my question is; is it the fuel pump, or is it a wiring problem? does anyone know where the fuel pump wiring grounds to exactly? where do the wires for the fuel pump lead to in the engine bay?

i'm going replace the pump regardless (has nearly 300k on it), i'd like to know where the wires end up in case it may be a bad ground.

thank you for your help.

 

main relay is a possibility too.

listen for clicks when you prime the key.

 

gf civc did the same thing .. everything looked fine gettin fuel , spark .. but when i say gettin fuel it was gettin it to a clogged fuel filter .. pick one up like 22bucks or less

 

i replaced the fuel filter & the car started up.

Thank You.

 

check your rotors/igniter in your disturbutor. I had the same problem with my civic. I changed the igniter and everything was working after that.
