[DMCForum] Re: Do Fuel Accumulators just Die overnight?? I'm confused here..

["Joe OBrien" <joeyoseppijoe@xxxxxxxxx>]

Walt,


Dave suggested to take a look at the thermo time switch. After 
researching it, that sounds like a good direction to look. I've 
never heard of a fuel accumullator just quitting overnight, and on 
one of my previous cars I had to replace a similar type coolant 
sensor because the car wouldn't run cold with the bad coolant 
sessor. It is kinda like the air fuel mixture doesn't know how to 
adjust for luke warm starts right now. Just all the way cold, or all 
the way hot. S shot of ether temporarily fixe the luke warm issue. 
I'm going to try my luck with the thermo time switch as it is 
origonal, and those style switches seem to die overnight. For the 
price ($25) it's worth a shot. Then I guess if all else fails I can 
look to the accumulator. Things like this make EFI sound so good on 
our cars.
