I am looking for some information concerning the PCM circuit on a 2003 chevy silverado 4.3L 4X4. I have blown the PCM fuse twice. Both times have occurred when I have a low fuel condition. Is this related to the fuel pump? Any help on this would be appreciated.

| Had engine light on. Originally had 2 codes.(P0300 & P0171) After research, I saw it could be numerous problems to kick those codes. I monitored the indicators and deduced H20 in gas took out the O2 sensor so I changed the O2 sensor yesterday and reset code. The light came back on and I am now hearing a clicking or sputtering sound coming from the rear of the truck. It coincides with the gas petal, as I accelerate it sputters/clicks if I let off the petal it stops. Possibly from the gas tank or exhuast. I suggest it is the fuel filter or the fuel pump. Any suggestions? | |
i replaced fuel pump on my 98 chevy silverado 5.0 engine, vortech. My problem is when I try to start truck gas from fuel injectors will not click and pass the gas into carburator. ANYBODY GOT A SOLUTION FOR ME APPRECIATE ANY ADVICE.

Hi Everyone I have a 1997 chevy Z71. The other day I was driving down the road and it just quit. I troubleshot the problem to an inop fuel pump. i replaced the pump........not a fun job.......and the filter. THE DARN THING STILL WILL NOT RUN!!!!!!!!!! I pulled the two steele lines behind the throtle body and have fuel under pressure there. If I pour fuel into the throttle body it will run until that fuel is burned up. Any ideas as to why I can't get it to run???????????
