1986 2.4L 4 cyl. HB won't start

It turns over well, but the injectors don't seem to be pulsing. I'm getting air and spark, but no fuel. There's fuel going to the TB but its not getting injected. I'm going to check the relays tomorrow, but I was wondering if anyone had any other ideas of what it could be. Thanks.

Fuses are good.. Fusible links are good... relays are good... ecu test is good... swapped the top half of the TB with one from a later d21... still wont start.. anybody have any ideas??????

there is a blue relay on the right side (pass side) with 2 separate plug in's.. by chance does
it click when you try to start it?? if so, have someone turn the key to the start position and
tap on the relay, if its not totaly gone your truck should start. (I think that relay runs about $15) oh wait.. you said it turns over, sorry, if that relay goes, it will not turn over.

I'm going to try changing dizzys.. someone said the crank angle sensor could be messed up or dirty or something.

After I rebuilt my engine I had a similar problem. It turned out the ECM wasn't putting out a ground signal to the fuel pump. The electrican added one and I ran it that way until I could find a used ECM. It worked fine after that. Now I have other problems to worry about.
