good hour or so. motor has ben sitting for a year or two, I think all injectors are stuck, speartec did the pcm and wires and i don't have a code rearer yet, maybe for christmas, for now i need info on testing injectors or replacing them. can i just use a test light to see if the pcm is pulsing the injector, + to the hot side and - to the ground side of the injector and turn it over should flash hu u think. hillbilly in need sorry about all the wording and stuff like <..>_ that little line is bullshit in case u was a wondering. don't useily work on motor like this. thanks

You can try soaking the injectors in SEAFOAM. I have not used the stuff, but have heard good things. There is a way to check pulsing with a digital voltmeter I beleive, I know I read on here, don't know how myself. Try using the search option?

cranking with a regular test light you might see it blink, usually the pulse is too short to light up the regular light bulb test lights. If you have an LED test light, you should see it no problem.
Most likely, your injectors are stuck. You can momentarily apply 12v+ and ground directly to the injector, just dont hold it on for very long at all. You should hear a click. If it doesn't click, likely stuck. The above mentioned sea foam trick should help.
I built an electronic circuit, with a 555 timer from Radio shack, that will pulse the injectors. It has a **** on it so i can adjust the speed. I have used this with good success un-sticking injectors. Soaking the injectors and at same time having them pulsed works like a charm.
good luck.

thanks for the info, I used a noid light and the pcm is working fine, thay all flashed, I might just spring for new injecters. I shot some gas in the intake and it ran on that. so at least I know it will run. I like the ider of making your own pulser, I look at one the thing cost $140.00. I found a set of injectors on ebay for $200.00 recondision but sound good. http://stores.ebay.com/Fuel-Injector-Connection if any one can tell if these are any good.
