I was up in the north woods over the weekend and when it was time to leave, my 2000 100 would not start. She's always fired right up except when the key fob battery died. This was very similar, good strong turn over but no action. Even though the key fob battery was only a year old and the immobilizer light went off, I rode the Zuma 10 miles to Walgreens so I could test with a new battery since I had to wait 3 hours until my son got there to drive us back home anyway. That did not help and I did not have time to do much other diagnosis other than check all the fuses.
All indications point to the fuel pump - it is 27 years old and has 235,000 miles on it. I replaced the fuel filter about 8,000 miles ago.
HOWEVER, as it cranks, the CEL and the red A/T TEMP lights stay on. Is this normal? I had the transmission flushed or something when I bought it less than 20,000 miles ago, the engine was cold and the fluid looks good. Everything I read says that the A/T light will NOT stop the engine from turning over, but I just want to make sure I'm not barking up the wrong tree. It's 40+ miles to the nearest Toyota dealer. I will have to bring all the tools and the new pump up and replace it over Memorial Day weekend so if a new fuel pump doesn't fix it, I have to go back home without it again while coming up with a new plan.
Any suggestions on alternative faults? Something else I should bring up there for testing if it doesn't start?
