Hey, Ive had the car gone through it was starting real hard when cold. Idling rough but under throttle plenty of power and smooth. Now i went to start today and it just cranks away. It sat for a long time before i got into it and I'm thinking the injectors are junk or jammed up. Any input appreciated...

Air, fuel, spark unless those are checked it's hard to troubleshoot on just a no start description as it could be anything. Check if it getting spark, check if it has fuel pressure, check MAF etc. Depending on where it has been stored and how long bad gas or critters on the wiring harnesse.

If it sat with the same gas for a long time, the gas is now bad. If you ran it like that, the plugs are probably now fouled. With E10 fuel, anything past 3 months or so and you run the risk of it going bad, even with Stabil.
