hard start?

[rodneykolk]

Hi everyone. i'm new to the forum. i'm a dodge cummins guy myself, but i have the opertunity to buy a cheap ford. its a 2000 i think. 7.3 6 speed. the owner of the heavy truck shop i work at bought the truck at an auction down in seattle a couple years ago and it has just sat there. we've had it running a few times, but it is VERY hard starting. the glow plugs have been replace i think, as well as the intake heater. however. i the glow plug relay may not be working. when its cranking there is a bit of black smoking coming out. it takes a super long time of cranking, like probably 10 minutes to get her running. when it finally starts, it chugs a bunch and if you give it throttle it won't rev up until its warm. i've driven it a few times on the road, and up some descent hills, and i think the power is fine, (kinda comparing it to my dodge when my chip is on STOCK) possibly a bit slower. it has 230000 miles on the odometer, but that no longer works, so who knows. what should these engines be good to? could it be hard starting because of low compression? it doesn't smoke white or blue when its warm, so i'm not sure. sorry for the long post, but i hope someone could help. its a descent looking truck. thanks Rodney

actually the glow plug relay is working, but not coming on? could it be the engine oil temp sensor bad? or possibly the cam position sensor? those are what i was thinking possibly?

the CPS would cause the engine not to start at all. have you changed the batteries??

[Jake]

If he cranks it for 10 minutes id have to say the batteries are good. Bad injectors maybe.

[rodneykolk]

but it runs fine when its warm. thats the thing. idles fine, so i don't think the injectors are bad.

the GPR is probably bad. CPS would make it either not start at all, or run very rough and die at random times. Whats the ambient temp?

[rodneykolk]

the outside temp when we've started last was probably 3 or 4 degrees. so i guess about 40 farenheit. but that being said. we've probably tried when its atleast 15.

Did you have the block heater plugged in? I'm still betting GPR

[rodneykolk]

monday morning i'll try it. its sitting in the shop, but it will still be about 5 degrees. so i'll try jump the relay. or maybe i won't, because then the price might go up
