Is it normal that when battery voltage goes down while trying to start that the trunk and fuel door pop open?

It rolls over normally till the battery runs down with a jump box connected. I'll have to get starter fluid tomorrow as auto parts stores are closed here now.

How do I check the coil packs for proper resistance? What should the resistance be.

I did get spark. Yellow to painted frame cross member at front of vehicle, battery is weak. Security light did go out on dash.

The car has had check engine on since I bought, I did not look for security error, I will.

I have not verified spark, to do so I should pull plug wire and using a screwdriver lay close to frame point and attempt to start car, watch for spark during start attempt? All 8 spark plugs were replaced today, I'm surprised the car ran with the look of them. recommended for this engine is .050 inch, the old ones were at .080 or more.

Is there a way to test the regulator? I have a lot of trouble codes the check engine light has been on since I got it. Can I pull the codes without a scanner?

I had an issue about a week ago where the car stuttered and stalled. I have replaced the fuel pump and fuel filter. I have what appears to be good pressure at the test port. It just turns over and won't start, Injector fuses are good I can see voltage across them. Where do I go from here? I only have today to solve, must work tomorrow.
