I just bought a 2001 4 door longbed. The truck has been sitting for about 4 months from what i can gather. The truck runs out fine, but it has a super long crank. My 95 fires right up so i dont know what this is. ITs warm here, so glow plugs arent it. Wondering if anyone had a suggestion as to what i should look into first. Weak starter maybe? Everything seems fine, and looks fine. Any suggestions would be helpful.

One of many scenarios is that the high pressure oil reservoir *may* be leaking down Slow cranking rpm can certainly do it. You can't rule out other HPOP problems.

There are diagnostic routines developed for these sorts of concerns that are designed to reduce the chance of replacing good parts and achieve a timely repair to the concern. I can only sugest obtaining the appropriate manual for your truck and following the procedure for you concern.

There are many pattern failures but, even then some diagnostic effort can go a long way to resolving the concern in the least amount of time with the least cost.

First thing I would do is change the oil. Helps when mine starts doing that.

I too have been experiencing longer crank times, but only with a warm engine. I am overdue for a oil change. I'm at 4,000 miles and I usually change it right at 3,000 miles. I'll change the oil and post my results later today, 6-18-05.

Oil change didn't seem to affect my longer crank times.

If you still have the original batteries, your close to the end of there life cycle. /ubbthreads/images/graemlins/smokin.gif

Changed my oil, was a little low. helped out a great deal on the cranking, but still not good. I think the batteries are going in the crapper, and maybe the starter too. Thanks. Dan

My truck also had long crank times. After talking to a couple of people I discovered that the bleed hole in the fuel pressure regulator was plugged. I cleared the hole and no longer have long crank times. The bleed hole can be found in the bottom of the brass piece that the spring seats in in the fuel pressure regulator.

Did you have long crank times when hot and cold? Mine cranks longer only when warm.

Randy

 

[Dubco1]

Both hot and cold were long crank times.

Thanks, mine is probably a different problem.

FOMOGO,

I'm curious about the bleed hole issue. Do you happen to have any pictures or details about what to look for? I have an early '99 that I bought new and have since put 142K miles on it. From day one it has alway had a long crank time. I took it in a couple of times under warranty way back when but they never found anything. I'm always interested in pursing potential fixes when I hear about something I haven't tried.

I'm the one that told him about the bleed hole so I am sure i can help you, look at the return fuel line connected to your fuel bowl. Disconnect it and pull it away. Next unbolt the two bolts that hold the regulator cap to the fuel bowl and remove and be careful to not drop the spring. Pull spring out and then pull the brass plunger piece out. Now look inside this brass plunger piece and there should be a tiny bleed hole at the dead center. If not, then it is plugged and you need a fine piece of wire to unplug it. After this put it all back together. BTW, if you havn't done the fuel pressure shim mod, this would be an excellent time to do it.

Hummmm, Thought this wad a hard starting thread /ubbthreads/images/graemlins/shocked.gif. I just installed 2 new Optima Redtops. OMG what a differance. Mine cranked for a while for about the last year. Last night it would crank forever and not start. WOW what a differance.

Uh, fixing the bleed hole in a plugged regulator fits perfectly in this thread because a plugged bleed hole could be a cause of hard starting. Gee imagine that, maybe my post about fixing the bleed hole was on topic after all. After all, FOMOGO had a hard starting problem and his fuel pressure was not bleeding down after shut down. I informed him that there is a bleed hole that would cause his fuel pressure to bleed to zero and he should look into that because ITP diesel had reported that back in the R&D days of the regulated return systems that the non bleeding down fuel systems were causing starting problems. Ok, what more can I say?

Clearing the bleed hole fixed my hard starting. So how are weak or dead batteries related to hard starting??? Slow starting as in turn over? It all relates to the original question in one way or the other.

Easy guy's don't get yer knickers in a twist. I was off track and thinking of something else SORRY /ubbthreads/images/graemlins/grin.gif

 

[ToddStyles]

Hammer, that was an excellent explanation of how to locate the bleed hole. Looks like I need to go ahead and pony up for the fuel pressure gauge and do the shim mod as suggested while I'm at it. I'll let you know how it works out.
