First post, and I feel like an idiot...

I have a 1991 Civic STD hatch with the stock dpfi system and now it wont start

Basically, I drove my car to work fine and when I went to go home it wouldn't start. My first thought was obviously the battery so I tried to pop the clutch and it still refused to start.

Wasn't the battery, the car turns over fine.

Got the car home and checked EVERYTHING I can think of.

The ECU is not throwing any codes, The spark plugs are firing, I replaced the entire distributor thinking it may have been the ignition coil rotor or some other part.

When I turn the key on to the second position I can hear the fuel pump, and I even have pretty good fuel pressure.

The car just refuses to fire.

I replaced the old 4 speed transmission with a 5 speed Si transmission some months ago and it ran fine afterword. I am at a complete loss as to what the problem could be.

 

It's turning over, just not starting? or just not doing anything at all?

 

maybe the distributor rotor button fell off or you didn't tighten it correct...!!!

 

LOL. that happened to me a few months ago!

 

Its turning over just not starting.

The rotor is on just fine, haha.

 

Do you think the problem could be a faulty main injector?
