Ok, I'm totally stumped on this issue. I recently bought a 93 Honda Civic with a D15B2 MPFI conversion already installed and the car ran for about 2 weeks and then one day died while on the highway. It's been 2 weeks and I've yet to get it started again. The car cranks but never starts. I'm not sure if there's even combustion.
It's getting fuel, the main relay is new, new spark plugs, new TD-02 distributor, p06 ECU(used), and the timing belt isn't broken. I've checked all of the fuses in the car and all are good.
Even though I was getting spark before, I was almost 100% certain I had a bad distributor, so I've already replaced it with a TD-02 as recommended by others who've done this swap and now I'm not getting a spark at all.
Can someone give me some advice on where to start troubleshooting this problem? I have a Haynes manual so I can reference where need be. Thanks

Does fuel make it to the cylinders?

Is there bright white spark at all 4 spark plugs?

CEL codes?

There is definitley fuel in the cylinders, whenever I removed the spark plugs they are covered in fuel.
I have to check for spark again since installing the new distributor but just from the way it was cranking I don't think they were sparking.
I'm getting CEL code 6 which is nonsense.

Unplug the ECT sensor and then check whether the engine starts (after airing out the flooded cylinders).

Ok, so one of the wires on the ECT sensor broke. I reconnected it and plugged it in and still no start. I unplugged it and still no start. Same CEL code.
As for the no spark issue I'm having, It turns out the distributor I purchased is an OBD-0 and the car has been converted to OBD-1 for the mpfi swap. After reinstalling the TD-42u distributor I'm getting spark again but still no start. The engine cranks and sounds like it's going to start but dies immediately.

It's getting spark and fuel, what should I check next?
