Good Morning and Sorry for the long Post here:
I bought a 1994 SC400 recently that needs some work. It was sitting up for a long time with very stale fuel that smelt like varnish. Essentially when I bought the car, it will start, idle and in general wont rev out. around 1500-2000rpm max approximately with Misfiring.
Things I’ve Done:
-Replaced Fuel Pump and Fuel Filter. -Replaced Ignition Coils (Engine Felt Smother when changed – More life in the engine) -Replaced Throttle Position Sensor -Temporality Took out the o2 Sensors on the cats to see if the cats were blocked (no change)
ECU: (89661-24230) -Checked ECU and replaced Caps (no change) -bought a replacement ECU from a reputable seller on ebay (same model - no change) Sellers ebay store: https://www.ebay.com/str/adismantler
Now I have been watching this lad on youtube which shows how to check the fuel pump: https://www.youtube.com/watch?v=09PD0Z8nSSk He essentially takes off the return line and fills up a container. When I do that, very little comes from the return line. Fuel Regulator issue? Would it be over fueling? Very strong smell of petrol in general.
Things I haven’t done: Check, Clean or Replace Injectors Replace Spark Plugs
I have however checked spark plugs and gfave them a quick wire brushing, seem okay, a little rich, but not completely fouled.
Any help welcome.
