ok my and my boss have been tryin to fix his S10 he bought a lil while ago.
hes replaced the fuel pump, the sending unit, all the relays to it, and today bought and installed a new ECM. and when he turns the key to the on position all the light on the dash come on but the service engine soon light. and the light not coming on is the problem its not telling the fuel pump to pump he found some way to bypass the problem and it starts fine.
does anyone have any idea what the problem is? i think hes going insane
thanks guys
