I'm having cold start issues which I've only had since replacing my fuel pump, strainer and fuel filter. I changed these as the fuel return valve is in the pump as was suspected as faulty as I only ever had hot start problems and my fuel pressure was dropping instantly rather than holding as necessary after the engine was switched off. There's a little difficulty with hot start, but not as hard to start as when cold and nothing like it was before the pump was changed.


I suspect, dirty injectors not closing properly, which is causing some difficulty in hot and cold starts which seemed to imrpove after a new fuel pump, for about a day.

I never had cold start issues with the old pump.

So, I've been thinking about wacking in a set of new injectors. Someone suggested first trying a bottle of fuel system cleaner in the tank.

If cleaner doesn't work, then I shall remove my injectors. Should I send them to an injector specialist or simply replace them?

If I replace them, is there something a little different from the stock replacement that I can go for that'll be pretty good? I see some from Accel that seem to be a few hundred cheaper for the set.

As the throttle body needs to be reomoved from the plenum to get to the rails, can I actually leave the throttle body in situ and remove only the plenum?

Tips and hints guys, I'm sure there's plenty of people out there who have done this and can reccommend injectors and injector things to do.
