1992 Chevy Suburban starts but wont run! Was running fine. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My '98 Sierra had a similar issue, after tracking down and testing every underhood electronic component Someone told me to replace the Cap and Rotor. I couldn't believe it would be that simple, I just replaced it 3 weeks before doing a tune up. A tow truck ride and $250 later I got the truck back from the shop.

Guess what they did? They replaced the cap. Seems the caps sometimes form hairline cracks and causes cross arcs, effectively shutting the system down. Sounds to me like the door slamming may have pushed a faulty cap over the edge.

Or shook a connector loose somewhere... Yeesh.

I would recommend looking at the simple things before spending lots of time and money on other potential issues.

Just my 2 cents.
