New 14mm guy needs help!

[matchew]

Just got my new 'hotrod' IP installed, new holley blue, new lines, etc. Already had +40hp Bosch injectors, figured they would be okay for now. Got everything in and put the pump to the head (exactly what the pump shop said to do) and cracked the injectors...started right up! Seamed a little doggy off idle let it run a few minutes and exitedly jumped in for it's 'maiden voyage'. Got 100 yards down the road and it started smoking white and the idle dropped to nill...WHAT GIVES?? I idled it back to the house in reverse and shut it off, now it won't even try to start. I am so pissed!

The pump shop said it made so much fuel they had to back it down...I got it yesterday and the tag reads 20% over stock. They said it's a starting point, and I can go up from there. It has the Rocken Tech (sp?) 14mm head in it, if that means anything for the troubleshoot. Guys, PLEASE help me...I've already backed the timing out of it and checked to make sure the pump key is in the groove. I'm lost and want my truck back!! I've been stuck driving a gasser dakota for a month and am missing my beast!

I know what caused the pump to die...sh!t veggie/diesel mix. Could my injectors be fouled????????

first of all the holley blue wont supply enough fuel given it is only 9 psi or there abouts and about 40 gph thru a 3/8" line

You need 20 psi inlet pressure and a lot more flow than that blue junk will provide ie about 80-90 gph flow

what size fuel lines from tank pickup to IP?
What are you usin for a fuel filter?
What are you usin for a water seperator?


ditch the veggie

20% over? over what? The 14mm makes about 60% more fuel than the stock 12mm does ie a maxed 12mm makes about 220 cc's and the 14mm without tryin makes 360 or more cc's all the way to 435 cc's

timing is? internal timing is? max timing is?

You can not just slam the IP to the head and know you have the correct timing

Pulling timing out made it worse? - I would be suspect that you are not timed correctly at all, cuz timed properly on the gears and jammed to the head would be abut 20 degrees timing static and the thing should sing.

what cam plate did they use? what internal advance setup? What fuel pin did they use and is it set in properly

I'll get al the info on the pump today. Are you thinking not enough timing at the outer adjustment? Seems strange it would start right up, then just lose fuel and die...it's pretty much the same as before the new IP. The whole fuel system is new with a full tank of #2. I realize the new H&R makes more fuel, it should at least start an run on the blue. I have it un-regulated and it is putting out 16 lbs. I need more, I know, but it's what I have for now.

there isnt a blue pump made that makes 16 psi pressure - only the Holley Black pump makes that and it isnt enough

your guage or sumthin is junk

start n run with not enough fuel pressure to the IP ?? so its starvin to death for fuel with less than 20 psi

Test your fuel system - get a pail and discconnect the line at the IP and use a length of hose to be able to get to a pail and then turn on yur holley

At 88 gph advertised free flow for a blue pump you should be able to pump 1.46 gallons of fuel in one minute into that pail

if not then start lookin for where the bottle neck is

100 yards down th road? Is there a chance the KSB activated and pulled timing out and drop it below what it would run with?

Where'd that pump come from? I think I'd take it back where I got it under those conditions: Ran a minute, then died? WTF?

[JAyers]

It could have sheered the woodruff key on the pump shaft. Sounds like a deff timing problem to me.

[seeker1056]

given how much trouble we had the firs ttime we exchanged pumps - tryin keep the key centred in the slot and centered in the keyway of the gear and havin got one key half sheared the first time thinkin we were in the right spot - i might suspect timing as well even tho the key "looks" right.

White smoke n blue smoke is timing for sure - just ned to determine what the cause is - skipped a tooth - too close to the head, lines on wrong/mismatched etc

[matchew]

I'm going to re-time the IP, pull the timing cover and check everything out. Can the timing gear jump while the pump is out? I didn't think it could...need to check it out. As far as timing and such in the pump...I didn't get a chance to call today, try manana. The KSB isn't hooked up yet, I'm wondering if the fuel could have warmed the truck up fast enough to make it smoke? If not enough timing the fuel is going in too late and just burning, not exploding??

Will the blue work at all? I bought it before I knew I would be getting this pump built...I'm hoping it will work for a daily driver until I can pick up a black or something else.

Ace...I'm sure the pump isn't the problem. Gotta be timing, clogged injectors, something in those areas. The pump shop (nameless til I get this right) will clean, pop test, etc. my injectors for free unless parts are needed. Just got to pull them tonight and take them to town. I'll get them back by noon manana.

Bump to the top....got the injectors out. I'm thinking a head gasket and a set of o-rings is in my future. #3 injector had motor oil on it, guess that's NOT supposed to be there? Anyway, I am still needing some ideas. Injectors go in in the morning, I know I need some bigger sticks...just no money after the new IP. What else should I be looking for? I;m pulling the front of the motor manana (sorry for the spanish, seems to flow better...thinking about a Negro Modelo in Puerto Penasco keeps me a little more sane! ) I hope the timing jump on the gear will help. I guess time will tell, eh?

[seeker1056]

did you check yur fuel flow into a pail yet?

[matchew]

I didn't have a pail...tried it into a parts pan and it filled up QUICK. prolly help 1/2 gallon of fuel and I almost sloshed it over. Had to move the truck a little (4 lo, reverse, starter engaged) anf forgot to hook the line back up...20 seconds later I have the Exxon Valdez oil spill under the truck!!!

Sounds like something failed in the pump. I would pull it back off and take it back to your pump shop and let them check it.

[matchew]

Too late today to get it back to the shop, going to try and get the front cover off and re-time the gears...jumping a tooth while I'm at it. Got my injectors back and the were 45 bar off of what they are supposed to pop at (245 bar from what I've read/heard). That calculates to roughly 600 psi too low and possibly a retarded timing issue, does that sound right?

I'm going to do the timing thing and try it, if nothing else I'll pull the pump this weekend and get it back to the pump shop for a look through. Thanks for all the info, hopefully I get to drive this neast soon!

[crewcabxlt]

lower pop pressure will advance timing, could still be part of problem. good luck.
