they dont look burnt or worn infact they look new becuase the wetr antifreeze are constantly cleaning it they just fail overtime go to a junkyard and get a couple or buy a new one thats what i did it was somewhere around 16-17 dollars

this probably wont help much but who knows when my car wouldnt start befor the sensor while the car was hot we searched and found thet the fuel pump relay didnt work ,it would prime the lines but would give out once it tied to start and we replaced it and the sensor and ive been beating the s**t out of it since then with no problem.

i mean i could only see it being a problem if it was hot, but it isnt...the thing is cold (the car) but i guess it might be a sensor sayin this doesnt work dont let car start kinda problem... and i i dont have an engine light either...

ok i checked the gas flow...i disconnected the line that feeds fuel to the filter to the fuel rail, and it comes out in squirts, wut could that mean...i knoe it might mean not ebough fuel at once to cause proper combustions, but if the fuel pump is pumping, wut could cause the low fuel flow?

dont **** with your injectors... was the car running before this happened?

check your ecu for codes.

it will tell you if your cts is bad(should) mine does(stanza ecu)or if you own an ohm meter/multimeter you can check it that way as well. stop buying stuff. DOes your tach move when trying to start. Again a code check would tell you this.

you check them yourself. remove passenger kick panel use a 10mm socket and extension to lower the ecu,put car to start but not fire,insert small flat head and turn the screw it says which way on the ecu....

your gonna have a 21 IIRC your primary ignition signal. I'd start with a junk yard ignitor. IF thats not it(and your coil is good) look into a dizzy. sorry for your luck
