pump not working after sitting for one year?

pump was working over one year ago with no issues. ran new custom tank and new lines. went to hit button to prime kit and had nothing coming out of hoses. removed pump to see if lines were clogged or pump was not working right. hooked up direct power and ground and pump kicked over. installed it all back together and hit prime button on controller and had meth flowing. took car for a ride and hit prime button and car stumble and a/f's went into the 9's with ease. rolled into the throttle and the red light comes on but does not swtich over to green and the a/f's are the same in the xfi data log as with no meth. is the pump not making enough pressure? am i missing something? thanks guys

you didnt say which system but ill assume your talking about a razor (alkycontrol) system

not to say there isnt a problem but

1- went to hit button to prime kit and had nothing coming out of hoses.
priming dry system will take a while especially with the gain turned down as the pump will spin really slow
but you could have a leaking pump which is why its taking time to come up

2- installed it all back together and hit prime button on controller and had meth flowing
so it does work but with a pressure tester you cant be sure how healthy the pump is
3-took car for a ride and hit prime button and car stumble and a/f's went into the 9's with ease.
looks like its working properly

3- rolled into the throttle and the red light comes on but does not swtich over to green and the a/f's are the same in the xfi data log as with no meth
up till now youve been using the prime button .. if red light comes on at about 6psi then youve confirmed a map signal activation of pump . if you are running with gain low it will take more boost to change over (approx 12psi)
also the reason why the logs may show no change is possible how your xfi is setup , if you test when first started the car is in open loop until warmed up and you will see the af drop , usually the setup is to delay closed loop until 120deg coolant temp , once in closed loop then xfi should be correcting the afs to your AF table .also at idle the AF targets are leaner and injectors flowing very little so it takes less alky to make it overcome the correction ability and send the afs to 9s
at 6psi which is where hte turnon point should be the injectors are flowing more and the af targts are lower so if xfi is doing the corecting thing it should remain constant even with alky flowing ..what you should see in closed loop is the o2 correction jump to pull fuel and a drop in the injector duty


check the pump pressure
he sells a pressure tester kit which is a nice thing to have to occassionally check things out and know if the pump is getting weak, check the component operation or to find leaks and such.

with all that said if in doubt you can always call razor and have him talk you through some tests on the pump or the system, or you could always send the pump or controller in to razor and have the them checked out .


ps . if you're not on a razor kit all i can say is a qoute from millenium man .. "sucks to be you"

i have the tank mounted on the firewall and a line going inside the front fender feeding the pump which is mounted to the front bumper brackets. the line going from the tank to the pump is about 4.5' long. the pump is an older one with permatex in teh joints but no sleeve on it. the xfi showed no 02 correction at 13psi from the regular old 93 octane tune. withot touching the tune i would have thought i would have seen the xfi running rich and trying to take out at least -15 in the correction? when i rolled into it to test it out i had the controller on the halfway point if i remember correctly. this is on a turbo 6.0ls motor too if that matters. i may have to take it out again to do a full third gear pull and see what happens.

i have a 3 bar map sensor in the car. im hoping to run around 20-22psi and put down 900+ all said and done with the meth kit. when the car is running and i hit the button the led goes red and the motor stumbles and the a/f dip way into the 9's. its a fully built 6.0 with a pt88 turbo, motor is 9.1:1. only running 13psi for the moment as im dialing some stuff in. i dialed it in on 13psi where the correction is as close to 0 as possible at 11.0 a/f setting. with the meth on the 02's did not change and the a/f stayed the same. this setup was in the car when it had the buick motor in it. i believe it still has the turn on point as it was set from you back in the day.

yes dual nozzle ill have to take this week in it to see. i know when i get on it i only saw red but i did not stay in it long. ill roll into third gear and wind it out and see what it does.

sounds good ill do that test first to see if it goes green on a single nozzle setup. thanks for the help on this.

ok hooked up it so only one nozzle was getting meth. turned the knob all the way up, started car up and hit test button. it instantly went from red to green and bogged the motor down. how do i set this up for an LS motor running a 3bar map and shooting for 18psi for now then 20-22 later on. thanks razor

Already on the market??

I made a low psi "tester" for the Innovate w/g system. It is a low psi gauge, adj regulator, some hose. It works well. Why not use something like that to put "boost" to the MAP sensor?? [I used it to avoid sweeping the engine up w/ a broom.]

yes im plan on making well over 700 at the tires. i will hook the dual nozzle setup back up and make a test hit this weekend with the setting on teh knob almost all the way up. i think the reason it was not working from the beginning is the long line i installed with the new tank needed time to fill maybe? should i have it come on at 6-7 or 4-5 psi? ill post back when i get a chance to take it for a ride, thanks guys

When you do...

"ill post back when i get a chance to take it for a ride, thanks guys "..............Take some oil dry and a broom with you....

no oil and broom needed, lol. im gonna spray the meth on the pump gas tune and low boost. xfi should show some serious correction if its working correctly. might try tonight but most likely not till after xmas.

took the car out for a quick ride. 15psi and the knob at about the 6 postion as soon as the boost fully started riding in at 15psi the light went from red to green. gonna finish the straight pump gas tune and go from there after.

well after a track rental im assuming the system is working correctly lol....9.26 at 153.3 just a little over 19psi.....
