1987 K5 Blazer TBI 350.

Was sitting for 7 years. This is what I have done so far

Emptied old gas
New fuel pump, filter
New pickup coil, and ignition module
New battery
Injecters cleaned and tested

I have a previous thread titled "TBI no fuel". Started a new thread because I've narrowed it down some.

It runs perfect when I put gas on top of the TBI. Im getting gas into the TBI, But injectors won't spray fuel

What gives power to the injectors. Any Ideas?

thanks,

Check the fuses for the ECM in the fuse box. Should have one that says ECM-B and ECM-1. The ECM-B is consant hot. The ECM-1 is ign power for the ECM. Hope this helps.
 
Pop the injectors out and look for corrosion / junk from dried up gas in the filter screens / passage ways.
