Hey guys... first time poster... looking for some help here...

I've got a '98 Ram 1500 5.9... I did the hughes plenum fix, changed out the plugs, wires, cap and rotor.

When I go to start it up... it almost makes a pop noise and everything goes black. Doesn't crank or anything. Any ideas?

I thought maybe the battery was weak and gave it an overnight charge... still the same deal.

 

Are the wires correctly routed ?

 

I matched it up just like the old one that was in there

 

Check grounds. Especially the ones up by the power steering pump. Make sure they are all clean, and tight.

Verify your firing order. No. 1 is marked on the cap. Clockwise rotation. 1 8 4 3 6 5 7 2.

There is a TSB in the faq section for plug wire routing. Might wanna give that a look as well.

 

The only ground that I can think of that might be iffy is the one that comes off the alternator - that goes on the A/C line / Air Cleaner bracket.

Should it be on the very bottom underneath sandwiched between the brackets and the accessory drive mount?

I didn't take any grounds off near the PS pump.

 

So long as it grounds, I don't think much else matters.

I have two on a stud that I had to pull to be able to move the wiring harness out of the way.......

 

I'm going to re-check the wires again... but even if they were mixed, wouldn't it still crank?

Right now, it doesn't even crank... the power just goes out.

 

Check your battery connections, I bet one is loose.

 

Make sure you ignition coil is nice and tight if not battery. My just need charged

 

well... I'm not sure if I'm any closer to the a solution or not...

Last time I tried it... after the power went out... it came back on (fading) and the check gages light came on... then the voltage on the cluster showed low.

I pulled the battery from my car (chrysler 300) and the power faded out again... but this time there was a buzzing right after... lasted maybe 5-10 secs and stopped.
