i have a 1996 ram 1500 5.2 M/T the truck cranks but will not start.. original codes were p0 1 2 3 p0351. i tested the TPS and the CPS bother turned out good results...i have spark and correct fuel pressure. also i cleared all of the trouble codes and attempted to Test the ECM by disconnecting the DIST. and the CPS and cranking it attempting to throw new codes but with no results. anyone have any ideas? i need to know how to either test the ECM or if you think it may be something else. also checked timing and it is correct

 

Are you getting injector pulse?

 

im not sure ill be at the shop in a few but i did try spraying starting fluid into the intake wouldent it atleast try and run even without the injectors pulsing if i did that?...and sorry about the other thread. this is my first time on here and i poosted there first by accident before realizing i was supopose to post in the main section. my apologies

 

yes the injectors have pulse...any onther ideas?

 

Are you getting spark at the plugs? Have you tried holding the gas on the floor and cranking it? What does your oil smell like?

 

there is plenty of spark...the injectors are pulsing but the light is a little dim...pulsing but dimley...also have tried the pedal on the floor with same results and the oil smells of fuel...not terribly but definatly noticable...

 

Got a scanner? Plug in, and see what the ECM thinks engine temp is.

 

also im getting dim spark from wires and bright spark from coils

 

Check all your grounds, on the engine, and for the PCM, and make sure battery is fully charged.

 

coolent temp is what its reading...i got a mac tools computer...and the temp is 71.F
