Engine/Transmission (1994 - 1998) Hard to start 96'...???

[CumminsPuller]

My brother-in-law has a 96' CTD and is experiencing some hard to starts. The truck will start, but takes a some seconds to do it. I had him change his fuel filter, but no help. If I recall he said it does not happen all the time. Any ideas, or things for us to check?

I'd check the return lines, if it has been awhile he should probably change them. If they leak air the truck will have a hard time starting.



Here is another Thread about a '96 with hard starting problems. A lot of ideas are put forth on this thread.

Check to see if the fuel solenoid is always activating as soon as ignition is attempted. It should move up to let fuel by. It's located near the lower, aft end of injection pump. Might be the relay for this id going. Good luck

The first thing to check for hard starting problems is the idle setting. If it starts easy when the pedal is pressed a little, then increase the idle. If that doesn't fix the problem then investigate the other possibilites.

If it is not the fuel return line then replace the overflow valve. I did that and no problems. Last resort may be the lift pump.

Reviving an old thread here. I had originally started this and appreciate all who chimed in. But his truck fixed its own problem. Until now. Brother-in-law just called me and said once he turns the truck off it takes anywhere from 30 minutes to 90 minutes to be able to restart. This is happening everytime he turns it off now.



Now a month or so back when he changed his fuel filter he said there looked like antifreeze in it. Is that possible or was he just seeing some green diesel?



But the part about haveing to let it set, reminds of some sort of thermo-switch that once hot opens and closes once cooled down. I don't know... .

check the fuel solenoid

It's very easy to check the fuel shutdown solenoid and eliminate it from the list of possibilities. My truck acted very much the same. It was an intermittent problem then went away and then came back and wouldn't start at all. I ended up changing the relay and it's been fine since.



To check to see if the fuel shutdown solenoid is the problem:

1. pop the hood

2. try to start the truck, if it doesn't start leave the key in the run position

3. get out and check to see if the solenoid is in the up position, if not push it up

4. if it stays in the up position, try to start the truck again, it should start

If the solenoid is in the up position at step #3 when you check it, then you can eliminate the solenoid as the no start problem.

If the solenoid won't stay up at step #3 then it's probably the solenoid/wiring, if it holds when pushed up then it's probably the relay.

Let us know what you find...

TMitch... ... ... . Thank you. I will take this information tohim and gothrough the test with him. I will let you know what we find. Thanks again.
