6bt 5.9 cummins. Took it to the shops, 1said it was the glowplugs, & said they r under each valve cover. 2nd shop said 1 injector was leaking & could b the reason for the hard starting. 3rd shop said maybe injection pump is wrong pump or sum 1 put it in wrong,something about the timing of it, they drove the truck said its only making about 40% power, all 3 shops did not hookup anything to truck, just looked under the hood, last shop drove it & said it would probably b a couple hundred to fix, saying they might have to send injectors out for testing, & hook a boost gauge to Turbo, where r the glow plugs on this kinda motor? Is there any1 on this site who knows a gr8 diesel mechanic down here??? I can't afford to get my azz ripped off again. The last place my dad gave em $1400 to put in new injection pump & they went out of business. & truck still never fired up or ran rt.

THESE TRUCKS DONT HAVE GLOW PLUGS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

there is a grid heater under tha intake horn with 2 large wires going to it. you dont need it in FLORIDA. its already hot.

the men you are working with are IDIOTS other then possible the shop that said timing was the issue. what is your truck doing any white smoke that could def be your problem

That is what I was thinking,.. u might need the heater grid in the winter down here when it gets in the 20s & 30s, but that is not many days..it smokes grey everyonce in awhile, but other than that not really. I need to find a GD Mechanic close by.who's not going 2 rip my azz off.

If I remember right the grids won't come on unless below 25*F. I think it's more a lift pump problem. There's a mechanical lever on the side of the lift pump on the motor. see if there's any pressure needed to push it down after it's been sitting a while.

Yeah Betsy & blowing smoke. Its definitely not cold down here, there is a lever like thing on what looks like on the fuel pump,I pushed it down like 30 x & it did not feel any different from the 1st couple of times I pushed it down,truck still did not start after doing that? Only with starting fluid starts it. 1 Guy said do not use starting fluid!! He said use silicone spray instead. I just nd a GD Mechanic by me 2 take a look at this truck & fix it 4 me, or show me how to fix it & I will try. I just can't afford to get my azz ripped off again or mess the truck up more. I appreciate all of ur help so far..
