the fuel injectors receive voltage through a fuse, they are grounded on pulse width modulation from the ecm (pcm). circuits 10 and 20 that pulse ground the injectors are called drivers. check your fuses first

thanks a lot sir.... so it doesn't mean you can ground it to the engine block or elsewhere?
is the fuse located under the hood? or on under the dashboard in the driver seat....

Tinignan ng mekaniko kanina un kotse... nilipat un ground ng fuel injection sa intake manifold,ni check din un fuse sa ilalim ng dashboard sa driver seat.

it could be a computer box problem???

need your help...

Could be a problem in distributor if the fuel injector has no power supply?

malamang injector. bili ka surplus sa banawe. 800 lang pang sr20 kaya mas mura dapat para sa 4afe.

Sir may idea po ba kayo kung magkano un surplus na computer box ng 4A FE....
Narerepair po ba un computer box? Magkano po kaya

your situation as you stated has no power to the injectors. in this case, the problem is not the pcm nor the injector. listen to your question.

hinde basta basta nasisira ang computer box,..try to check muna lahat ng fuse or wiring line mo,..better to go with car auto electrical shop,..hinde sa car mechanic kung electrical ang deperensya
