if you're not getting a pulse to the injectors I'd 1st check the condition of the wiring and connection to the crank speed sensor that points to the front pulley
if this looks OK then I'd replace the crank sensor with a new part
I'd also check the condition of the ECU relay and fuses for corroded/ burnt contacts and damaged sockets
I'd also check the condition of the small ground wires that run out of the engine bay wiring loom and are secured to the engine with ring terminals and small bolts
and lastly check the condition of the MAF meter connector and wiring and that the flap moves easily under fingertip pressure
do you still need help?
