What's up guys this is my first forum post so bare with me and i have a couple of things i need answered and things I've fixed. Well i purchased a 93 LS400 and didn't test drive it before buying (probably should have lol) but it ran very bad and shook the whole car. You could smell unburnt fuel from the exhaust and was gonna see if it had a code but the dash lights dont work. I've purchased the specific capacitors and know how to fix it (basic soldering skillz). I jumped the gun and thought is was a spark issue so we removed the plugs, plug wires and tested the resistance on each plug wire and they were all in spec (less than 25k Ohms). Next checked the plugs and 1 and 7 have ignition firing residue while 3 and 5 were soaked in fuel. On the opposite side 4 and 6 had firing residue and 2 and 8 were soaked also so i found out that 2,3,5,8 (the ones soaked) where connected to the front most engine coil. Tested the coil and saw no power coming from it to the left side distributor and realized the coil might be bad. Replaced the coil and she purrrrrs like a kitten. The non firing cylinders had some oil in them for some unknown reason and smoked a little but went away. So I had it idling and gave it some gas and had a little bog in higher rpms. Then not thinking anything of it, I took for a quick spin around the block and ran well until i floored it and the car just died. Coasted to a stop tried starting her up but just cranked over for a second then died. Crank up for a second then dies again. Next thing i thought was the fuel filter since I know they usually cause LS400s to die on hard acceleration. Changed the filter to a new one, put my mouth to the old one and was pretty clogged. The new one flows so much better. But here's the problem, I replaced it, turned the key and same problem. Starts for 1-3 seconds then just dies, no matter what i do with the pedal. Checked ignition and its fine so definitely a fueling problem. Also I can't hear the pump prime anymore which warrants concern. I've heard of fuel pump relays going bad, or worse the fuel pump ecu or even worse THE ECU! We tested the fuel pump and on cranking it shoots fuel out like crazy from the filter. What do you guys think? Just fixed one problem to encounter another so I hope this isn't a vicious cycle. Also got a fresh $100 to whoever can help me fix this!
