at 45 mph car quits running, would not start
1992 SC400, 2nd owner (16 yrs), 128,00 miles, with less than 1 yr old duracell gel pack car acted to be cranking slower and resulting in slower starts. 1 start of the day sometimes had me guessing bad battery. Multiple starts of the day seemed less time to start. After making 3 stops (errands) and driving a steady 45 mph car died unexpectedly. I coasted into a convenience station (not that easy braking and steering). The car was much slower to turn over but all dash lights worked, windows rolled up and down. No ignition occured. I checked all heavy fuses in the engine area. Initially I thought the battery was shorted out? I removed it and took it home to put on my charger which tells the state of the battery which appeared to be normal. I put it under a 10 amp charge and it was not depleted and quickly charged to the highest setting of "being charged". I took a known good battery a large 850 amp battery and all though I could not hook it up to the connectors I did so through jumper cables and it would not turn the engine over.
I know I need spark, fuel and to crank it over well.
I've read about bypassing the fuel ecu or Fuel Pump control, is there an easy way to verify I have an operating fuel pump (listening for it or volt meter check?).
Is there a shrader fitting on the fuel bar I can push to see if fuel comes out?
Can I spray starting ether in the Throttle valve to see if I have ignition? Where?
The car is located in Stuart FL and I am seeking experienced mechanic to trouble shoot it.
