1994 2.4 No Spark...

just unplug the maf and see if it woks. the truck will run rich but should run fine.

you claimed to have replaced the ecm, was it a rebuild or new? more info is needed here. if you could pull it and take a picture of the inside of it without the cover on so i can see the bare board that would be great.

to see if its a fueling issue take a can of starter fluid and pull the vacuum hose off the manifold to the brake booster and spay a shot down it, plug the tube back in and see if it fires up. give this a try even tho you have replaced the fuel pump. ive had brand new pumps from napa fail months after replacement.

try these things first before throwing more parts at it. chances are its a maf or ecm. the 2nd gen trucks weakest link where the ecm-maf-timming belts-front lower control arm bushings. other than those they are pretty solid.

Pulled the MAF and still no spark. Cleaned it, still no spark.
It is getting fuel, i pulled a plug and could smell the gas.
Definitely a rebuild ECU. Pics below:

I have traced all wiring for continuity (even the connectors) and everything checks out.

Im about ready to drive it off a cliff

i dont what else it could be. if the new ecm does not fix your issue than i would replace the engine bay harness. i dont know if you have access to any pick n pull but they are 40 bucks out the door. plus they are easy to pull out. takes me less than 20 minutes to swap.
