Hi All. Odd problem and I'm stuck. 88 CSX-T. Stock electronics. Been off the road for more than a couple decades now. But it HAS run in the past few years. As recently as last summer for sure. I decided it's time to finish it and bring it to SDAC this year. Or at least drive it as finished as I can get it. But there seems to be a problem with the injector circuit.
When I crank, I get good fuel pressure and spark, but the injectors don't fire. But if I spray in a bit of starting fluid or gas, it kicks of for a second or two. I discovered it by accident, but if I disconnect injectors 1 and 3, it will start and run roughly on cylinders 2 and 4. If I connect 1 and 3, no start. Disconnect 2 and 4, starts and runs roughly.
So far, I've changed the fuel (it was old), the injectors, and even the injector harness and I'm getting the same thing. Fuel pressure is good. Changed from the Mopar Performance computer back to the stock one, too.
Any one else had this one before?
I'd really like to take this to Detroit, but I may have to start prepping the Rampage if I can't figure this out soon!
Thanks!
