Starting issues.

[Sparksy35]

Well ladies and gents I'm at a bit of a loss. my 94 6.5 TD is having some trouble starting. I'll turn the key let the glow ugs warm then il attempt to start it and it'll crank and crank and crank and try to start and it will eventually start after about a minute or so of cranking and hitting the gas pedal.

Sounds like air put a clear fuel line on the return coming out of the IP

On a 94, I would do the lift pump relay upgrade, regardless if that has anything to do with your current issue. Jumper the lift pump and let it run a few minutes before trying to start. Install a fuel pressure gauge. It will save on future diagnostics

Does it puff smoke out the exhaust while cranking it? If so its probably a glow plug issue. If not then check for air in the supply fuel system like the others have mentioned.

yea actually. once it gets going it blows a good deal of smoke.

I've been considering putting in a new lift pump just for good measure.

So, the clear 1/4” ip return line is fast diagnostics to say if the fuel is going through the ip.
having enough fuel now and to make sure you dont shorten the ip life is why you want a fuel pressure gauge on a T right at the ip inlet to a gauge on the dash you read while driving (cranking in this case). But that is not gonna fix It right now, but do it asap. If you can do it now it won’t hurt anything and can tell you if this is the issue. Dont mess with a new lift pump until the gauge is on there to tell you the current one is junk. 8-14psi for ds4.

I don’t think it is based on the smoke once it does start. Make sure that smoke smells like diesel fuel and not coolant.

I think you are having cRank speed issue, or glow plug issue not lighting the fuel as it should. Whats your cranking rpm. Post a YouTube video helps if you can

Don't install a new lift pump for good measure. Install fuel pressure gauge for good measure. Then you will know exactly what your lift pump is doing. I'd do the lift pump relay upgrade ASAP also

ok do I'm really new at this... how do I do that.

For the lift pump relay, if you aren’t comfortable making your own harness, buy one from Leroydiesel.com

The fuel pressure gauge, put a “T” in the fuel line just before the ip inlet, and buy a pressure gauge that uses a sensor. You should not exceed 14 psi, so dont get a gauge the reads really high like 100 or the range you use will be hard to read. There are mechanical pressure gauges that could run fuel into the cab, but modern electric gauges are easier and accurate. The gauge will show how to run the couple of wires, but most are simply 1 wire from sensor to gauge, then power wire to gauge, and a separate power wire to the gauge light which you tap off you other dash lights.
