So this truck sat for a few years before I got it. I picked it up and it started off of starting fluid. Fuel pumps were dead. At some point I also lost spark. So I replaced distributor plugs rotor and tfi module. I got my spark back. Then I replaced both fuel pumps and filter and pulled the injectors and cleaned and tested them. I’ve also replaced eec relay and relay connector along with fuel pump relay and connector. It will crank and fire but will not start! I pulled the ecm took it apart and it had a leaking capacitor so I got another one and soldered it in. Still no change! Also it runs amazing on brake clean. I’m at a loss. I really want it to run and I don’t want to scrap it but I’m about to give up! Please help
