Question about 1997 Chevrolet Blazer
In order to get my blazer to start I have to crank and crank and crank. I've got good fuel pressure and no check engine light when it runs. I've also replaced the fuel filter and Cap and Rotor. This is just driving me nuts.
Have you done a leak down test on the fuel pump? If the pump check valve doesn't hold pressure the fuel drains back to the fuel tank, then you have prime the lines with fuel before any is delivered to the injectors, hence a long crank time. Install a fuel pressure guage and start the engine, then turn off the engine and wait overnightm the system should not loose more than 5 PSI
