0k . i seen a few threads with similer pr0blems like mine but n0 luck . i have a 97 ram 1500 with a 360 magnum . i was drivinng the truck all week and it started first click all week , then the 0ther day i went t0 star it and it just kept turning 0ver but didnt even try t0 fire. i checkd the fuel and its g00d ,the spark is fine .i put my c0de reader n it and it came up 02 senc0r,the truck has been runing a little rich but i think it will still start. the truck just sudenly didnt want t0 start . any advice w0d be great . thanks

 

What is your fuel pressure? Does it remain steady while cranking? Are the injectors firing?

 

Where did you check the spark? If you checked it at the coil, it's still possible the distributor cap and/or rotor are shot.

 

You can have all the fuel pressure in the world but if you have a bad crank sensor or something to keep the injectors from firing, you ain't gonna start.

 

i checkd the spark at the plug and its g00d. the fuel is getting t the rail cuz i pulld the line 0ff it and when i pulld the pin it blu 0ff s0 smthing is telling the inject0rs n0t t0 0pen. im a little strapd f0r cash at the m0ment and trying t0 find the pr0blem with0ut putting up a crap l0ad 0f m0ney.

 

A Crank or Cam position sensor will throw a code (and check engine light will come on) when cranking if they are bad.

 

ill pick up s0me sens0rs and see h0w it g0s .. much thanks ...cheers

 

money saving troubleshooting ----

try mashing the gas pedal when cranking. this bypasses the IAC idle control and the closed throttle plates of the tb.

try spraying in some starting fluid. this bypasses fuel and injectors.

if you have spark at the spark plugs, its likely that the crank and cam sensors are ok and the problem is "most likely" fuel related.

 

Wondering out loud
Would a collapsed/plugged CAT cause it from not starting, and throw the o2 code?

 

Even a completely plugged cat would try and fire. From what im getting from the op, its not trying to do anything, just cranking and cranking. Hence is fuel or spark related.
