1987 Silverado Fuel Issue

[scorpion1110]

Just talked to my friend who bought this.

He popped in a new ECM, the Truck ran for about 45 seconds and then shut down. He said it fried the ECM- could smell it.

So the diagnostic told me it wasnt bad, though I had a hunch - turns out it was.

So ideas what would fry it?

Even though its not my headache any more- I do want him to get it running.

Thanks as always.
