i have a 98 305 crate engine in C1500 and i test the schrader vavle and i have 52 Psi with key on then at idle it runs about 50 psi.....if i let it sit for a minute with the key on it will drop to 40 psi. it has the new spider injectors and reg so i dont think its that. It used to whine louder then any truck i have heard and all of sudden i cant hear a thing. on the snap on scanner i get a fuel level sensor code and have an erractic fuel gauge too.
one more question i replace the alternator at idle its about the 13 then while driving its a little before 14 and i did the Big 3 Upgrade. any ideas i either of my problems....any advice would be great. this site has helped me through my whole engine swap. Thanks
