    Hmm, just off the top of my head I would also check both IGN fuses in the fuse box.

    Was there any other work done to the vehicle??

    Just trying to narrow down cause. Be it something unplugged or mixed around plug wires etc etc.

    Popped the fuse a couple times without identifying WHY it was popping? Not smart... Just saying! Fuses pop for a reason... And now what the fuses that kept popping is connected to is not working! Hmmmmm... Do you see the pattern? Not being a smart @&&, but you've obviously got to trace out and identify why that happened. Not sure too but sounds like you're shotgunning parts at the problem with all you've replaced.

    Fuel, Air, Spark... And it should run. You say fuel is good, air is good... Said nothing about spark?


    You checked Ohms on injectors, have you hit them with voltage and seen them open/close? There's a write up somewhere on actually testing, rebuilding them... Anyways


    And like FFDP says, you've moved and replaced so much, its easy for something to be not connected, or broken wire.

    If the car will run on starting fluid then the IGN circuit is fine. You are also good in the air and spark department. Your issue is fuel related. I would double check the injection fuse. If it is popping then you most likely have a wiring short on that circuit. First thing I would do is unhook all injector plugs and crank the engine. I will assume that the fuse is popping when you are turning the key. If it doesn't blow the fuse with the connectors apart then you have a shorting injector. If it does blow the fuse then carefully check all the wires for the injectors.
