ok so i have a 2000 chevy silverado single cab witht the 4.3l vortec v6.ok so for some reason it cranks but wont start. at first the fuel pump would build the pressure and lose it because the injectors would stay open. So i changed out the spider assemby with the injectors and pressure regulator all that good stuff. it solved the lost pressure problem. but it still wont start. the spark plugs are good and they are sparking. so idk what to do
replace the plugs, they're cheap. Make sure you're getting spark. Make sure you're getting the injectors to fire. Did you maybe leave something disconnected while fixing the spider assy? Check all fuses and ground wires, too.
Make sure you have to connector going to the spiders in all the way. I had a similar issue likes this before and it was that.
ok thanks yo ill try that tomorrow after school im still in high school so yeah lol and ill let ya know how it goes
