Dear veed,

Hope you're well and stay so. When the RPM (crankshaft position) sensor fails, the loss of its signal causes the Engine Control Module (ECM) to shut-down the fuel pump.

So, the first thing to do is to replace the RPM sensor. If the in-service unit is factory original, it is long past the end of its service life. I suspect you'll find that the insulation sheath has cracked or even fallen-apart. If the wires touch, or if moisture gets to the wires, that causes signal loss. The fuel pump at once shuts-down.

The Idle Air Control Valve (IACV) may also need to be cleaned. See the site's FAQs for guidance as to how to do that.

Hope this helps.

Yours faithfully,

Spook
