I recently purchased a 1990 LS400, when i bought it car started fine and i didn't drive it far (couple miles) my plans are to restore the vehicle. Now that i have the car home it statrs sometime and other times it just cranks without firing. The fuel hand was slightly below 1/4 tank so i pour 2 gallons of fuel in, cars started right up. Few hours later car wouldn't start poured more fuel in car started again.
Next day car wouldn't start, so i changed the fuel filter then poured in gas that had drained from filter change car started again. Next Day, you guessed it no start. Also the instrument cluster lights blink three or four times after i try cranking it sometimes. does anyone have any suggestions on what might be going on!!
Car starts sometimes after pouring in fuel
Blinking Dash lights
When the car does start it's an instant start and the engine idles string and smooth.
Could this be a security system problem, fuel pump, relay, fuses
Thanks for any help
