Where the relay or sensor injectors 99 quest ?

What make , model an year vehicle ? Could be a relay problem , power hold relay for ford , ignition 1 relay for GM vehicles or ASD - auto shut down relay for jeep , dodge , Chrysler vehicles . Asian vehicles have them too , Honda - main relay powers fuel injectors , coils etc.... Do you know how to do basic automotive electrical testing ? Check for voltage ? You would need to look at a wiring diagram for your vehicle , see which wire powers the coil an injectors etc...test for B+ voltage ! Videos on you tube showing how to test ignition , fuel etc..

When you turn ignition key on ( not start ) does the checking light ,light ? Check fuse's for PCM , are they good ? Find a wiring diagram an check power an ground at PCM . Also hook up a scan tool an see if it will communicate with the PCM . That's how you check the PCM ! Also check the constant control relay module , these go bad an they have fuel pump relay , power hold relay , this powers up fuel injectors an ignition system !

Sometimes a crankshaft sensor does not send the signal to fire either the spark or the fuel injectors. If the fuel pump relay is not getting power, the inertia sensor will not have power either. The inertia reset is just magnetic and does not depend on having power to reset.

You can check for current at the Inertia sensor and at the fuel pump relay. You can also have fuel pressure at the test port without the injectors working, which is the easiest test of all,

You need the sequential firing pulse for the injectors. Have you checked the EEC Relay?

hello good day, reverse your air filter, make the bottom to top,, if is not work change the high tension wires

It's might be immobilized try the spare key or get it code read that should point u in the right direction

Have you checked the automatic shut down relay ?
It powers the injectors from a 20amp fuse number 5.

sounds like a immobilisor fault try the spare key first in case the chip has fallen out the key or its been wiped by a mobile phone or a body scanner

let me know

look on injector pump make sure there are no loose wires
