Car shut down following and dull sounding knock not metallic. Found map sensor plug had fallen out. Tested spark plugs with spark gap tester found no spark Check all fuses and can hear fuel pump come on when trying to start. Could the pass lock 1 be holding out the spark and not the fuel pump? What would be a go starting point to trouble shout. I do not have a code reader, and no way to get car to one. Can I trigger code flash some how? PCM fuse was pulled and replaced a couple of times.

Take car to some autoparts stores and get codes read for free.

Call ahead and check first, but most Advance Auto Parts stores read codes for free, and Autozone also.

Also u can go to autozone or most auto stores rent a code scanner with just a deposit. Full deposit back when device returned u can pick one up for as little as 20 bucks and works good!
