ed pepe 01 ford zx2 dohc, manual need a fella with car smarts
so changed coil pack, spark plugs, spark plug wires, crank sensor, cam sensor MONTHS LONG BEFORE the issue happened. everything was smooth and running fine. then all of the sudden while going to work there was a p0303, didnt think anything of it at the time. shut the car off but hours later when i came back. red pepe did not want to go vroom vroom.
it turns over like a madman with plenty of battery juice, it just doesn’t wake up. timing belt rotates and seems and feels as solid as ever and check engine light goes off on start indicating ecu receives signal from crank sensor.
pulled the plugs all gapped at 53, all nicely gasoline coated, there is pretty nice spark on all 4 plugs , i ran my obd scanner and fuel pressure on key on engine off after the pump is primed data shows 216 to 225 kpa which translates to 31-32 psi.
the charts i am seeing shows a minimum of 35 psi on the short range for fuel pressure.
is it accurate to say the pressure is too low and that is not allowing fuel to pressurize and spray well enough to fire up? should it still fire? is the ecu fuel pressure sensor not good? or what conclusions or steps can i take to bring pepe back to life?
