Ok so the throttle body seems disabled and I'm not getting fuel. Is there a way to bypass it? Somehow get power to the throttle body and injectors?

so you're all going to laugh, but I re-checked the fuses and somebody stole my fuel pump relay.. So I put one on there and.. well My injectors work again. Now.. I don't have any spark.. haha. If it's not one thing, it's the other. Anyway all the wires and the coil packs have power, but there is no spark.. Any ideas?

Even funnier ... there is one !!!!

The PCM uses relay 42 to power the coils. Check Fuse 16 as that protects the PCM circuit. Obviously make sure the relay is there. The fuse and relay are both in the underhood electric center.

I've got a 4 cylinder '97 Sunfire sitting in my driveway that's playing with my mind the same way. But it sounds like you're having twice the amount of fun!

Did it run for any significant amount of time since the May 12 entry? New codes? Any chance the fuel pressure could be low and be starving it?

That's the weirdest part. There are no error messages. It sounds like it's coming from the engine, but I have full compression, so could it be the bottom end? Everything appears fine, it's just that when I start it it makes like a clunking sound and then after about 5 seconds it sounds like something is grinding, almost like when the pullys squeek. It's not the pullys though, my friend said sounds like a bad piston, but I dunno. I originally thought something was just loose, but it also eventually stalls. Any ideas?
