will crank and start for half a second then shut off. my original post and updates of what i've done so far is on clublexus.com (please go to the link below for extensive details of what i've done so far).
i am getting spark and there is no issue with MAF.. i am thinking is a fuel issue but older model lexus its hard to tap into the lines to check fuel pressure working on a mod to test pressure after fuel filter, inlet to fuel rail. i am actually thinking about taking off the cartech FMU off temporary because sitting so long i think diaphrame and springs inside the FMU are stuck.. maybe its fuel pressure regulator thing (stock one on the car) but it doesn't leak gas when i take vac hose off.. now i am thinking about pulling the entire fuel rail off and check each injectors (but i am not sure if thats the problem). when i spray starting fluid down the intake it does start for about 1-2 seconds then dies.
changed valve cover gasket, new plugs, wires, engine oil, coolant, (planning to change out the rotor and distributor this weekend too. tested the OHM on injectors shows 13.9-13.7 on all 8 injectors but maybe clogged due to being in storage for 12 years. my biggest mistake is not draining the fuel so in the beginning i had to deal with crystalized fuel tank.. cleaned it all out and changed fuel pump (replaced with walbro 255) anyway since it seems like more folks are modifying V8s here so i thought to get some advice here. wondering if there is anyone out there that is from the LA CALI area that might be able to help. ironically this supercharger kit was purcahsed from Lextreme himself. what i put on my car was his prototype.
