Crank but no start condition is caused by either no compression, no spark, or no fuel, incorrect timing is your most likely cause unless you have an anti theft system installed that is disabling injectors. If the distributor was never touched before the problem then I wouldn't mess with it. Sounds like you have spark and have replaced most of the fuel system I would lean towards engine timing. Possible your timing belt snapped or jumped a few teeth. I would check compression first to make sure your engine is still good. If compression is good then you have a problem with fuel. Possible bad ground for injectors or a faulty pcm.
Try taking it to a shop that can hook it to an analyzer and find the problem. Cheaper than buying part after part in the hope that the next one will be the right one.
its your spark! yellow fire wont do. i believe the coil assembly on the distributor is the problem. after cranking it over are the plugs wet and you can smell gas?
Need to know if it is a 2.2L (4 cylinder) or the 3.0L (V-6) Camry?
Clean and tighten the battery cables.
yellow spark is weak for one thing. it should be blue.
New fuel pump. .new fuel filter. New EFI relay...new fuel regulater..spark plugs fire yellow. .what else can i try to get it running? ?
