I didn't have enough room to explain in question. So, yes, I'm driving down the road, the motor just stops running and won't start again. I've checked my fuel pump, I've checked my engine control relay, checked for fuel pressure right before the motor. New plugs wires cap and rotor and made sure coil is throwing a spark. New oil pressure sensor etc. Now, I did run a jumper wire from the battery to the fuel pump contact in the engine control relay and it's started twice. But the other 100 times it won't. The last time it started, as soon as I gave it about half throttle it shut off. Hasn't started again, I'm thinking ecu, but I wasn't able to test it, and I don't want to spend 300$ and it not be the problem. Any ideas?
