GPRs non emergency

[95stroke]

Well I hardly post,but ...
I've been going through GPRs like 1 every 2-3 months.
Been using the NAPA GPR -111

I'm kinda at a lost as to why,,,every thing that I can think is good..

probably because the aftermarket glow plug relays arent really glow plug relays and will not hold the amperage correctly, get a ford one and it will fix your problem, the ones you are buying are more like a starter solenoid and are junk

don't but it from a dealer its way too expensive, instead find a local International truck parts house they are much cheaper and heavy duty as well.
