2000 7.3 cold start problem

got a quick question. on my 99 super duty, its getting hard to start in the morning when its very cold. does this sound like glow plugs? I've heard that it can also be the controller for the plugs. any ideas?

oh, its got 340,000 some odd miles on it too.

Its probably the glow plugs, the less working the harder it is to start.

Glow plugs for sure, everyone else in my family runs powerstrokes. It seems glow plugs is just one of those things you have to change. I havent heard of too many controllers failing. The plugs wear out on a regular basis though.

it might be one of the relays. i had one of my friends come over and look at my truck. he took a volt meter and tested both relays. i believe that the 2 are the glow plug relay and the air intake heater relay, with the heater relay towards the grill. thats what my buddy said i have low amps or voltage. my glow plug relay was still good. he did say it might be the glow plugs.


ive got the haynes repair manual for Ford Superduty 3/4 and 1 ton pickups, 99' - 02' book number is 36060

the glow plug relay on the 7.3 powerstroke's are common for going out. they get to hot trying to heat the glow plugs in the winter time

I just had to do my controller. Ordered an el-cheapo from ebay, and ended up having to get a good one. Cheapo wouldnt complete a circuit. Grrr
