My son's truck keeps dying. It was acting up and slowly we replaced
battery, alternator, belt, tensioner pulley, ICM, IAC, fuel pump, fuel filter.


It was running like a champ for week or two. Peppy as ever, not a problem at all.


Now it can barely go 50ft. It starts to stumble and bog down, then just will not turn over.


Any thoughts?

 

where is the battery voltage now? (dash indicator or even better voltmeter with and without load - or does it turn over when cranking?

 

just checked on it. Voltage reads good per inside gauge. Cranked and revved like a champ. Back up strong. Put it in gear. Dead. Cranked up and alowly lurched into driveway. Doesn't want to idle know and sometimes isnt even starting. Juat turns over.

 

spark?

temp indicators? (sensors)

EGR?

Has to wait until next week - will be abroad and no manuals at hand.

Maybe you can give more symptoms. Automatic trans or manual?

 

Automatic. I'll pull plugs later and see how cap looks as well. I checked grounds on battery and alternator and all seems well.

 

Another thing that just came to mind:

- engine grounding strap?
