You're welcome.

Sounds like something isn't hooked up somewhere... the ECM isn't aware that the engine is spinning.

Check the plug hanging out the bottom of the dist.

But of course. The pickup coil pulses are on it, and that's how the ECM knows that the engine is spinning, and that therefore it needs to pulse the injectors. After all, if the engine is sitting still with the key on, no fuel is required; as RPMs increase, the # of pulses needs to increase; and SOMEHOW, the ECM has to be able to "see" the RPMs to know what to do.

Sounds like right now, it's "blind", and has no idea that the engine is spinning, and therefore that it needs to start giving it fuel.
