car not starting, alarm? ecu?
dont know if the alarm has tripped a shutdown mode or if i have stuffed the ecu when taking it out to see the chip
fuel pump does not prime but power is going to the ign amp, coil etc
alarm is a cobra 7925

have you got a multimeter???
if so check at the relay to see if there is power anywhere to rule out relay failure.
If powers fine at relay, measure volts accross the pump itself.
check inertia switch if you have one.
if not then trace the wiring to find out where the alarm isolates the fuel pump circuit and do a check to see if the alarm has isolated it.
Most alarms immobolise on a minimum of 2 circuits, usually fuel pump and starter.
