I am getting fuel to the injectors and the injectors are new. Any ideas why it won't run? I tried running it on Diesel, Biodiesel and starting it with brake cleaner. Nothing seems to work. The fuel pump is definately working but the engine won't even fire on any cyliner. I ran waste cooking oil for about 7,000 miles without any diesel and then was forced to use diesel and the car died instantly. I replaced the injectors and it ran but wouldn't develop any power at low RPM. It finally stopped running and I cleaned the manifold out and checked the spray on the injectors, but it wouldn't fire at all. I was hoping to start new with a fresher engine. But if it is a huge project, I have better things to do. Also the car has always been a real dog. It is the slowest thing I've ever driven, and I've had diesel VW vans. Also, the car would die whenever the engine was revved. It didn't keep the RPM up when the engine deaccelerated quickly. Maybe the injection pump and the computer are bad? Also, will the 123 engine fit bolt up and work with the tranny in the '87? I'll try some diesel purge and see if that gets me anywhere, but I think there are several things wrong with the engine and it is not worth repairing.
