93' Prelude fuel problems(HELP!!!) - Honda Prelude Forum

I am having fuel problems on my 93 vtec si. The distributer, ingnition set, fuel pump & filters, plugs and wires have all been replaced. The problem started with random stalling, I began working through the possible problems replacing the above parts. I replaced the fuel pump this morning after bleeding the engine and not seeing any fuel present. Now that there is fuel in the engine it starts and runs with a rough idol until I give it gas then it sputters and dies. Please, can anyone help me?

your description is not too clear, but i m guessing thats a spark problem...therefore it is most likely your ignition coil...see if u can take it out, and clean it up a bit...or since u ve replaced most of the parts already, you might as well replace it.

im sorta having the same problem my jdm h22 is running extremely rich, but today i went to start it started up fine, than died. I found out my starter is shot also but for the fuel idk, im throwing an 02 sensor so i got a wideband on the way and also an SAFC i hope those help. And you say you swapped a distributor that might be the problem i swapped mine also to get an external coil, and i think the ignition maps are off, im getting it timed weds. ill let you know if i figure it out.

its also possible that the ignition switch has gone bad. mine went bad, and my car would die out of nowhere, sometimes during start up, sometimes while driving.

Thanks for the advice. I just got back inside from disconnecting the o2 sensor now it's running, however idol is still rough and it still sputters when I give it alot of gas. The whole ignition set is brand new, so I know that thats not switch altough I thought it was at first also. I had it tuned recently also and the timing is dead on. Oh by the way the parts that I had mentioned in the original post have all been replaced with brand new oem's exept for the distrubitor which I got from Honda.

I just replaced the ignition coil today. Its running perfectly!! I sincerely thank you both Si_G & Rudaluda. Here's a look at my Vtec, I'll post some more in user gallery. I brought her back from the dead. Was i pieces when I got it. Used the interior from a 95'. All stock, gonna work on that though..
