98 caravan 3.3, cranks, won't start.

Hi, My 1998 grand caravan, 3.3, does't start, It will crank but will not start. I drove it 20' on a saturday to rake the driveway and when I tried to start it on Monday morning it wouldn't start. I checked for spark at the plugs and coil and is sparking well. I heard the fuel pump charge and I'm getting fuel up the carb ( pushed the valve on injectors and gas squirts out). I shot ether in carb and still didn't start. any Idea's? :disappoin

Turn your key from off to on three times leaving it on (not start). Count the number of flashes from the "Service Engine Soon" light on your dash. These flashes are two digit fail codes stored by the Powertrain Control Module (PCM). Flash, flash, pause flash is a code 21. There will be a longer pause between codes. A code 55 just means the test is complete. Come back and let us know what you got.

It wouldn't pull up codes, where do you find cam and crank sensors and how do you check them?

What indication did you get when you turned the key? The best way to read the codes is with a DRB II scanner. Autozone will read them for free if you can get it there. A scanner costs $80-120.
