does anyone know how to repair the insturment needle lights on a 92 sc400?

the spark looks weak

what would cause that?

the fuel pump is operating

i have too much fuel it seems

the right side cam sensor wire looks worn, the 2 inner wires are fine, but the ground around them is worn thru.

could this be the problem?

i have changed the plugs and the crank sensor.

still same problem, cranks over, has compression, spark and fuel.

seems to immediately flood.

ecu has no codes.

I think that you should clear all the fuel out of the cylinders/crankcase because your ECU might be in flood "fail safe" mode right now.

I pulled all the plugs and changed the oil, tomorrow i'm putting in a set of new plugs and see what happens. If it doesnt start, I think it needs cam sensors. I read that the cam sensors regulate the injector pulse and it seems too high.

the car floods when cranked, but has good spark and fuel pressure.

i'm thinking crank sensor, cam sensor or ecu.

what do you guys think?

the car ran great, then one day it wouldnt start again. it is in my garage and dry. with my snap-on scanner, i can get rpm reference, it has spark and fuel. seems like too much fuel. the injector pulse is 17.0 m/s when i turn the key on and 19.6 when cranked. seems way too high. maybe the quad driver in the ecu? any comments are appreciated. thanks guys

I have a 1992 SC400. It cranks over but doesnt start. I have spark and fuel, seems like too much fuel. Also, when I turn the key to on, NO Check Engine Light. That makes me think it is the engine ecu. Any input would be appreciated. Also, where is the ecu located? Thanks guys.
