Ive got a 92 SC300 5spd. Just replaced the valve cover gasket, alternator, button, spark plugs, water pump, timing belt. Car started fine but then acted like it needed gas. Gas gauge was just above E so put $20 of gas in it started and ran fine drove it about 10 miles no problem. Cut it off and replaced radiator and drove then drove about a mile and turned it off and went to restart and wouldn't start just turns over. Waited over night and then it restarted fine. Drove it about two miles and engine started sputtering and shut off and wouldn't start. It still turns over fine but sounded like fuel pump wasn't cutting on so did the straight wire to the fuel ecu and it cranked ran rough and as pressed pedal it would get even more rough and then it died and wouldn't restart. Replaced igniter and coil and still want start????

Any ideas would be greatly appreciated!!!
