okay, i installed a new fuel pres reg and gauge i got at the reunion, directions said no mods needed to the schrader valve, hooked everything up and the gauge dont work, regulator seemed fine, so i played with it a bit@car ran good, so i thought this would be a good time to install eric's chip. got that done, started the car, would'nt run more than 10 sec( yes i unhooked the ecm, more than once). fooled with it a few hours @no luck. decided to put the old reg back on @ no change. service eng light (key on) on but not flashing funny, normal. any ideas? :confused: DontKnow: :bleed:
 
Well your gauge probably isn't working because you have to pull the needle out of the shrader valve. All you have to buy is a tire valve stem removal tool for less than $5. I don't have any ideas on the chip problem.
 
Service engine light ON ? or is it the security light that is ON. Sounds like a VATS problem.

fuel will not come out of the rail without the shrader valve removed x2

check eng light when keyed on (not started), thats normal, i mentioned it because eric said dont start the car if its flashing( its isnt).bottom line it ran fine untill the chip was installed

Re-install the stock chip and see what happens.
 
im currently runing 3 of erics chips an my dad is runing 1 so that is 4 and all 4 cars ran 60% better an idled ALOT better after chip change. You sure you gave him your right specs ?
my 84# injectors idle just like a stock car

and ive had reds chips / joe lubrants chips no coment on his attitude / stock chips / and Eric aka turbo tweak chips

10-4 , right spec, stock chip so i didnt have to run alky all the time , i doubt its the chip, just something i did but ill be damned if i know what it is
 
these cars can be a lil bitchy at times ... ive walked away from mine many times an thought abt it an it ended up being a simple problem
 
Double check to make sure you have the chip installed properly. If memory serves me correct there's a notch on the carrier (chip holder) and one on the ECM and they have to line up. I'm guessing if you put it in backwards it wouldn't start at all.

it will only go in one way, also check eng light will flash if somethings not right

okay, put the old chip back in, runs fine. all i can figure is i ordered a 60 lb injector/ chip combo, but i hadnt installed the injectors yet, will do that today and try the chip again, im also going to pull the needle out of the schrader valve and try the gauge again :yes:

Hopefully putting the new injectors in will solve the problem since the chip is match flowed and built for the bigger injectors.:beach:

Yeah - but shouldn't the injectors pulse anyway, even though they are the wrong size? It is possible though since they might not be giving enough fuel.
 
Static electricity can fry a chip according to shade tree mechanic lore,
I've changed them a bunch and never ran into that, but I guess it's possible.
 
And laying on your back dropping that ECM can create a bit of static. Although it's typically more of a PITA getting the ECM seated correctly when you put it back in. Also changed mine a bunch of times without ever having any issues.

Check the new chip to make sure none of the pins are bent. If it is a problem with the chip, try to e-mail Eric and let him know what is going on. He is pretty good at getting back to you even on the weekends. Also, before putting the computer back in the dash, try to start the car. If it still doesn't run wiggle all the plus going into the ecm and try again. It could be a loose wire that got bumped and just a stroke of luck that it worked after installing the stock chip back in it. if it still doesn't work, I would definitely e-mail Eric.

like i said before if there any problems with the install (bent pins, ect) the check eng will flash, im thinking since the pressure gauge wasnt working and i was fooling with the regulator , i could have had it so far off it woudnt run long, anyhow i am pulling the tb@ plenum to clean everything, replace gaskets @install a rjc power plate, @ new injectors, now that everything isnt balls to the wall ( reunion) i can take my time and do it right :idea5:
 
it started raining on me about 2 pm & didnt stop, but i got the tb & pleaum off &cleaned, injectors are next, here are a few pics. I ordered a 160 thermostat this morning, anything else while im in here ? :feedback:

I hope you remember where all the parts go,LOL.:cheers:
 
Where did you get the 160 thermostat?

There must have been a sale on the magic erasers, looks like you are well stocked up.

got the thermosat from full throttle, yeah i know were everything goes, thats why i like to take my time. i have to be careful what i ask my wife to buy , she will come back with a 5 yr supply! lol :crazy:
 
I would go ahead and get a metal vacuum block, the plastic ones are known for not sealing well around the top of the throttle body and the plastic gets brittle and the nipples break off.
 
I second that on the metal vac block. Last time I removed the brake vac line I pulled just a bit too hard and broke the tube part for the brake vac line. Then my car was undrivable until I received the metal one. It's just annoying when something like that happens, easy to prevent at this point for you. Don't worry you'll remember where everything goes, your not that deep into it :)

I'm with you, the injector pulse width is changed along with many other parameters. When I put my turbo tweak chip in with the matching 42.5lb injectors, there was also a relearning curve with the car. It did run a little abnormal for a few miles but once the relearn was set, it came back to normal & full power was back on.
