Archived 2001 no start

[cj hall]

I have a 2001 dodge the problem is that it wont start this problem started a few months ago
the truck has o rebuilt VP on it new injectors new o rings on the works the fass pump is pumping at 14 psi, new fuel line from the dip tube to the injector pump. teflon stainless steel lines AN fittings.
yesterday it started doing it again. this is after 3 weeks of starting just fine.

any ideas?

Need to see what codes you have if any and let us know that will give some insight as to what may be going on. Without knowing that it could be a many number of problems.

Is the engine not firing or not cranking?

If it is cranking does it seem slow or different? Whne was th elast time batteries were checked? Have you tried a shot of brake cleaner to see if it makes a difference?

Codes?

 

[cj hall]

SORRY
no codes engine is cranking fine no fire in the hole

if you put a small squirt of starting fluid around the air cleaner it will start just fine i don't like doing it but it does work.

Have you verified this with a scanner? Sometimes your cel will not light up but a scanner may still pull a code. Do you know for sure you have good fuel pressure to the injectors? Thats where I would check first.
Also a possiblity it could be a bad crank sensor but thats just speculation i would get a scanner if you havent already

 

[cj hall]

the scan tools all show zero codes 3 different ones, smarty, inavo the brand new off the snap on truck solos pro said zero the next step is the dodge dealer scanner sorry the spelling is bad on the scanners names

First thing I would do is crack #1 injector line open, first one in front. Crank and see if fuel comes out. You might have gotten air in system. If your getting fuel with a VP, It should start.

The symptoms sound like it could be a bad VP44.



How many miles / months are on the rebuilt one and who rebuilt it (where did it come from)?

When you spray it to get it started, does it shut off and start again or not? Any white smoke on start up?

Hmm, you say the wife pumped the accelerator and it started? Bad TPS, perhaps? I've seen a lot of these trucks that wouldn't start without a full prime, but usually one they start, they'll start again... . With the FASS on there it should start fine... .



Try adding around 1/4-1/2 throttle and see if it will start. The APPS(TPS) may be bad on the low side. You could test it via the FSM voltage test, as well. I'd also check the grounds on the batteries. LOTS of problems start and end there.

the vp is less than 6 weeks old took it on one roadtrip to Colstrip Mt about 160 miles and it was fine started the no start when i got home then it went away for three weeks it was at the shop that fixed it they could not get it to do it i took it back and drove it for a week and then it started doing this again rebuilt by ? it's where they get all there pumps from G and J diesel is the shop its at .

no white smoke starts and runs if you turn it off no start it puffs black smoke on start up.

no start at 1/4 or 1/2 throttle back at shop now i just don't get it

Was your truck doing the no start thing before the pump change? Try to start it instantly when you turn the key. Do not let the lift pump have time to build up pressure. Electronics can do weird things. How are your batteries? They can spin the truck over, yet be weak. Stick a good booster/charger on the left battery and try it.

the truck was doing the no start before the pump change then it quit all the way took it in and had the pump replaced also at the same time changed the injectors. it started just fine for about to days then started doing it again took it back they found a loose return line got it back drove it to weeks and it did it again took it back the only could think it was sucking air somewhere so i changed the fass fuel lines (blue parker hose) to teflon steel braided hose for other reasons. drove it for three weeks and now its been back at the shop for to weeks.

i think its the rebuilt vp 44 pump but they are thinking something else

working 6 days a week 10 to 14 hrs a day does not leave me time to reply in a timely manner sorry.

the batteries are new still wont start both have 1247 cca each with a new starter also

 

[HHhuntitall]

I've had some that lose prime sitting several days... . Finally found the return line to be the problem. Another ended up just woudn't keep prime. No leaks I could find, replaced all the orings and fittings... . Finally added a check valve between the lift pump and fuel filter housing and it starts fine. Not sure where it's losing it prime, but it's still running with no leaks anywhere for several months, now..... Sometimes it's something simple, but it drives you nuts... .

hello to all

now its been over a month no truck and still no start they have cleaned the complete fuel system . so what do i need to get the engine to fire.
it needs to crank over, fuel , air all in the right order and at the right time.
is the rebuilt injection pump the issue?
is the starter the issue?
is it ??????

thanks

Based on everything you've told us so far, I'm still voting for a bad VP44, but I do have a few more questions:



1. Can you reconfirm that the engine runs fine AFTER you manage to get it started by using a squirt of ether (or the time your wife played around with the throttle)?



2. Have you tried HOLDING THE ACCELERATOR PEDAL TO THE FLOOR while cranking to see if it'll start?



3. What brand / size / style of injectors were installed? Are they new, used, and/or rebuilt?



4. Do you know where the shop got the VP44 from? Are you sure it was a quality rebuild?



5. Has the shop tried hot wiring the VP44 to see if that improves starting? I ask this question because it's possible there's something wrong with the ECM and hot wiring the VP44 eliminates the ECM from having anything to do with starting and running.



Regards,



John L.

Hello John

The engine runs fine no it runs great after it starts holding it to the floor does nothing when trying to start it. It has new bosch injectors
this is where it gets cloudy i have not asked where the rebuild pump came from but i will find out to day. and i will ask about hot wiring the pump
thanks for the reply

in the last 4 months my truck has been at the shop 11 weeks

and on top of this my 04 is not running right.

 

[JLandry]

i will ask about hot wiring the pump

Please let us know the results.



Good luck,



John L.
