Hello all, a couple months ago I purchased a 1978 280z that had been sitting since 2001. I started by cleaning and coating the inside of the tank, installed a new fuel pump, installed an extra fuel filter near the tank, and replaced the fuel filter in the engine bay. I also have a new fuel relay, efi wiring harness, ecu, and a new 3 terminal dropping resistor (the 5 terminal and new 3 terminal resistors tested good with a multi meter). I also replaced the spark plugs, spark plug wires, and the pickup wire from the coil to the ditributor.
When I try to start the car with starting fluid it will run but only when there is starting fluid present. I'm sure this means that I have good spark. So my problem is fuel.
When I did the FSM tests with a multimeter at the harness connector every cylinder checked out good. Each cylinder read the battery voltage meaning the dropping resistors and injectors have continuity from the battery and are good. I can also hear the fuel injectors click when I ground them through the negative wire on the coil. I can also hear the relays give a solid click when I turn the key to start. The power line from the battery to the ecu and the revolution trigger signal all read battery voltage as well and all my grounds also tested good. I know I am getting fresh fuel to the fuel rail because when I pulled on the inlet fuel rail line there was a bunch of fuel that squirted out. At first given all the successful tests, I thought I had a bad ecu, however I just tried starting the car with a new working ecu for the second time and it still wont run.
I went and read many posts on so many forums and scoured the internet to find a solution to my problem before wasting someones time and posting about it. However, I am stuck here and dont know what to do anymore. Even though I prefer EFI, I'm thinking of just switching to carbs because no matter what I do the damn thing seems to never want to run.
I did all my tests and checks but to no avail.
And yes the tach is plugged in.
Any help? I'm desperate to see this thing running.
