timing?

 

[frustrated inc.]

i know nothing about the timing. it seems to run ok when pouring fuel in the throttle body. i need to know first of all how to tell if the ecm is ok

First thing I would do is replace the fuse that controls the ECM. Second, did you disconnect the Neg. battery cable when changing the fuel filter? If not it would have reset the ECM. Or you could either have a bad ECM or bad power/ground supply. You need to do a pin test with a fluke meter. Start with the basics though.

can you explain the pin test and fluke meter thing. i did disconnect ground and i am pretty sure all fuses are good. is there another fuse other than on drivers side location?

would the camshaft or crank sensor be messed up if engine runs when pouring fuel in throttle body

Check fuel pressure.
