Fuel injection issue

[grittracing]

what is the best way to clean fuel injection system other than putting fuel additives in tank? tried no success ! 1980 Fiat spider. fuel injected stock engine

take the fuel rail off. get a bucket of acetone or something. bench fire all the the injectors with pressure on them.

I had my injectors done by a fellow that has equipment/tools to check and service all kinds of injectors. Perhaps try a diesel engine service shop. $25cdn ea. cleans, checks the internal filter,repaces tip if needed, checks spray, and replaces small seal.
I believe there was a place in Seattle WA (witchhunter.com?) that would give you a printout as well.
I don't know about the home method, but if it works, great,save a few bucks
