So I thought I had it fixed after it fired right up 4-5 times after replacing the fuel filter like it was a brand new truck. However, today my buddy told me its doing the same thing it was before that. I don't think its the check valve in the fuel pump, you can cycle the key all you want and the starting symptoms are the same. The pump will buzz the first time you turn the key, but on successive KOKO's, it is silent. The truck will start after about 10-15 seconds of cranking and run fine. No codes other than one for the oxygen sensors, which is due to it not having cats. Where should I start? I am suspecting injector/regulator issues, the truck has 288k on it. Whats the best way to diagnose that?
