I do not have a scan tool to check any of the major componants have you heard problem before ?
Expert:  Gary replied 4 years ago.

you have no spark at any coil and you have no injector signal blink when cranking ?

do you have a test light ?

if so can you unplug any fuel injector you can and with the key on does one terminal on the connector show 12 volts ? if so then connect your test light clip to battery power and touch the test light tip to the OTHER terminal in the fuel injector connector and see if when cranking it will blink your test light

also with the ignition key on is the check engine light lit up in the dash ?

The vehicle ran yesterday, now I have no spark at any cyl , I listened to the injectors and heard no clicking noise , but will check power and ground at I've injector connector, also after cranking I checked the plugs and they were not soaked with fuel ?
