Spark and Fuel? Need to test injector control. 200 1984

Kirk,

If you have spark and fuel, it appears your injectors aren't working. Art had this to say above...

"Next thought is injector wiring is shorted in harness, and injectors are not getting turned on. A borrowed 'noid light would prove or disprove that in 10 minutes. Wonder if the chain auto stores lend them out too?"

I vote for the noid light too, at this point (or sooner). But even if chain auto stores don't lend them, you might find one (Bosch type) for under $10. Just saw one for $2.99 on ebay. I paid IPD $6.95 for one on a weak moment some time ago.

They all look basically alike (see below) but terminals vary by FI injector type (maybe working voltage too?). You just plug it in place of an injector and watch it while cranking. It will flash if voltage (constant from Fuel relay) and pulsing ground (from ECU) are present.
