2000 v6 MT crank no spark

Here’s the deal.

was driving and it died. Found EFI relay to be faulty, I replaced it with a working one and it made it a few miles and died again. At first I thought bad fuel pump, replaced it. No go. Now I have replaced every relay, every fuse, replaced every ground with thicker gauge wire and cleaned all connection surfaces. Replaced battery terminal connections, cleaned battery posts. Still nothing, just cranks. Weird
Thing is it fired up the other day, came out the next day and no go. Have done an amp draw text, read .02 amps.
What do I check next? I’m about to light this thing on fire.

 

Got to figure out if it's fuel or ignition. I'd verify spark which is easy to do, if it's no spark or spark is intermittent it's possibly the Crank position sensor? It isn't a stick coil nor a single cylinder so the issue likely is common to all the cylinders which simplifies it a little.

 

It’s getting fuel, I can smell it and it backfires sometimes when I’m cranking it over. I tested the coil wires with a test light and they are all getting power.

 

Any codes? I wouldn't trust the test light for that spark check, get an old plug or pull one out and stick it in the stick coil and lay it on the valve cover and have someone crank it. I'm pretty sure the stick coils would burn out a test light when it's connected to the coil's primary (spark plug connection) so it's possible you measured the 12V the coils get all the time the key is on, that doesn't tell you anything sparkwise and unless the test light is designed to be a spark tester it won't even measure spark. The easiest way I've found to eliminate spark is the check I described or use a spark gap checker or else an inductive timing light. There's a possibility there's a compression issue but that'd be my last check after verifying I had spark and fuel.

 

I have someone bringing a code reader tomorrow. And I assume you’re right about the test light on the coil, it’s getting power but may not be getting a signal from the ecu. I’m burnt out on it today, five days straight of trouble shooting by myself has my brain and nerves fried. If it’s not fixed by Monday I’m admitting defeat and sending it to a shop.
