Fuel Injector test?

[billmcg]

Anyway I could check which injector would be bad on my v8 bronc (302)? Its missing and i've pretty much got it narrowed down to the injectors. Before I replace anything else I want to find out if my injectors are firing correctly.

I got this trick from someone else when I had problems with my f150, get a jumper wire and pull off a connector to one of the injectors, will have to do the test for each bank.

with the key ON reconnect the plug to the injector with the jumper wire stuffed in the plug, then touch the other end of the wire to the intake or another ground, never hold the wire against a ground for more then .5 of a second. you should hear all 4 injectors on that bank click open and closed, narrow it down to the ones that are not clicking. repeat again with an injector on the other bank to test the other 4.

good luck and hope this helps.

Thanks for the info guys... guess i'll hook up my meter to the plugs to see if they are getting power first. I think I might even be able to "backside" the connectors without even pulling them. Got stuff I have to do today so maybe tommorrow i'll test it out.
