Question....Random Sputtering going on in on 93 civic, and it has thrown the 43 CEL which is fuel system.

Change Fuel Filter, Changed 02, changed sparks, Dizzy cap.... What else could it be.

It happened a month ago when I moved back to STL, then it stopped.....then all of a sudden driving to class at SLU, then it happened again.

Any suggestions

I hoping I do not need to replace them.......They are pricey

How do you check and see if an injector is bad?

Still same problem, although I have not changed the injectors or the fuel pump yet. This time though when I started my car after viewing dark night,(about 10% of my fuel left), I hear this click click click noise and then the car starts. Sputtering hard for the first 5 minutes of me driving then stopping. i know the main relay is what primes the pump and that 100% good cause it was recently changed.

Deciding because of the money factor to replace the fuel pump and get a Walbro, or replace the injectors and get ones with higher CC. I will be installing turbo in the future and that is why I am not going stock.

One theory that someone suggested is that some how when I am driving the fuel pump is getting clogged with something possiblity the strainer. It causes the CEL light to come on. When I turn the car off the pressure loosens causing whatever it is clogging my pump to fall away from the opening, thus eliminating the CEL 43. that just a theory, still have not opened my Fuel tank to figure.

Need help, tired of randoming losing power and smelling exhaust....
Any suggestions.

thanks, when i get the bread, i will change that. Does it matter if I get a Walbro 255 or a stock fuel pump? They running the same price new, but I do not want to hurt my fuel system by getting a Walbro and not changing the injectors and such....
