hows it going guys I have a 95 c4 that’s been eating my lunch for about 4 months now can’t figure out what going on with this thing I’ve done just about everything except the Opti I’m 23 years old same age as the car it’s my baby tryna get this thing figured out ive replaced ecm and bcm both rebuilt . Changed fuel filter injectors oil pressure sensor/sender fuel pump as well , cleaned all grounds still can’t get it to run what it’s doing is starting up runs for about 3/4 secs then shuts off if I haven’t tried to start the car in a while it’ll have a really hard start but when it finally catches as I’m giving it gas (it want run longer than 5 secs) as it’s shutting off I can hear a static noise as if one of the plugs were open on either end checked them they weren’t had a friend start the car while I placed my hand on Opti and I felt a voltage coming from it is that normal ? I hear static but can’t see it . Before the car would run drive oil pressure seemed to be high if I gunned it car would kill and wouldn’t start back up until it cooled down now it just starts and dies .?sometimes smog would come out the intake as if there’s not enough spark burning off the gas a real funny sour smell idk never smelled it before but I’m leaning towards my Opti . Any c4 owners or specialist can give me any tips ?
