So i broke everything down to do the 00vi and realized i didn't have everything to complete it so i proceded to put everything back on. During all this i blocked off the egr and cleaned out all that wonderful carbon gunk.

Upon putting all the stock equipment back on i tried to start it and it just spun and spun.

It's getting spark and the fuel pump is sending but i tracked it all to the FPR. What i don't know is, does it open with that small vacuum line attached to it or does the fuel pump push hard enough to open it?

I was having a very hard time getting it started before all this but now it just cranks but never fully starts.

Any input is greatly appreciated!

 

FPR is the return line.

 

So the fuel comes through the filter to the rail closest to the radiator then out the FPR to the hose to the left of the filter? (all said if you're facing the front of the car head on)

 

i thought the FPR was on the inlet side. Its purpose is to hold gas in the inlet side when starting the vehicle so fuel doesnt have to travel all the way from the pump to start the car. Sorta like a check valve.

 

that was my understanding

but i just want my dang car starting and the fuel is being held right there

 

Why don't you just attach the vacuum line? And yes it does need vacuum to function properly.

 

i did.. i put everything back the way it was.. or so i thought.. and still nothing

 

That is correct.

 

Do you know why you were having starting issues before? Does the car crank and sputter and almost turn on but die?

 

well when it did crank it was fine but while starting you had to floor the pedal and just keep trying. i'd say at least it would take 5 attempts to get the car fully started usually.. but i just replaced the crank sensors and cam sensor as the last effort to fix that problem.

i'm gonna go down and switch those lines tho and see if that fixes anything

 

Sounds like a vacuum leak maybe recheck all the lines and are you sure the gaskets weren't super thin for the UIM and LIM?

 

nope they are brand new.. have yet to crank the car with them on actually

i poured gas directly into the vacuum hose off the brake booster and it turned over for a bit

 

fuel, air, spark.

Gotta check the 3. Maybe injectors arent firing .

 

haha i did that we got it down to fuel and it was stopping at the FPR.. and i'm guessing that it's a vacuum leak somewhere but i haven't the slightest clue as to where because there's no hose left open or anything like that and the gaskets are all brand new

the only thing that changed is the EGR delete which i didn't think would have anything to do with starting but it's looking like it.

 

the fuel does not come through the FPR to get to the fuel rail it EXITS the fuel rail through the FPR...

 

i fixed that part.. it's still not even trying to start tho

 

its like this on the return-less systems and the regulator is usually in the tank 97 have a return line and our "check valve" is or in the fuel pump

 

OP- how did you track it to the FPR? have you put a fuel pressure gauge on the line to see what you are getting?

 

well i just went backward to see where the gas was not getting through and found that it all stopped at the FPR.. but if the gas was trying to go through it the wrong direction then i understand

but no i have not put a pressure gauge on it at all cause i don't have one available and there was nothing in the line so i figured no pressure was there anyway.

 

what else have you tired?

the lines should go from the tank to the fuel filter to the front fuel rail around to the rear rail then the FPR then back to the tank

 

i have new IACV, MAF, crank and cam sensors, and i seafoamed everything (when it was running)

checked for spark and it's good, double checked the connections of EVERYTHING and there seems to be nothing out of place besides the EGR guide tube delete.

 

Did you block off the egr openings on the intake manifold and exhaust?

 

that i did.. maybe i need to use something thicker? or just put the dang tube back on there lol

 

Well if you blocked off right it should be good but if not you have a huge intake leak, check it out and report back.

 

will do

 

so i checked everything out and i put the tube back on with new gaskets and all i get is this.

 

And yes I know it's dirty ha that's not what's in question tho

 

sounds a bit weak is the battery charged? are the grounds clean ?

 

thats an electrical issue man. If u got spark, fule, and air, then either compression is off or timing.

 

Are you sure you got fuel now? You could have burned out the fuel pump or popped the fuse by having the lines hooked up wrong.

 

well the car was being jumped off if you look at the bottom right with the connectors on the battery

but does the compression or timing just go off like that.. do you not have to mess with it first or it's just an "old car" thing?

and that would suck seeing as how i've traveled about 120mi with this fuel pump.. but whenever i turn the key i can hear it coming on and i checked all the fuses and nothing's blown

 

it's also never sounded like that while trying to start.. the sound is usually a lot quicker and doesn't hesitate like in the vid

 

welp! i'm sending it to a guy from my hometown cause i'm exhausted and i don't have the time to diagnose it anymore nor can i afford to not have a car much longer

opinions are still open but as of now it's going to be picked up tomorrow

 

If the car started when you poured gas into the vacuum line then your issue is with fuel. Either your injectors are not opening or you have no fuel going to them. Also being a 99 you could have been immobilized which shuts down the injectors. Is your security light on when the key is in the on position or cranking?

 

Well if everything else checks out the only stuff left to check is compression/timing and ECU.

 

i've never heard of it being immobilized what does that involve and how do ya reverse it?

 

Well if your security light isn't on when key in the on position or cranking then you don't have to worry about it. If it is then you will need to have the dealer or a locksmith reprogram your key. It's a common problem with 99's and if you search theres lots of threads.

 

ha well there's a slight problem with that.. i wired my ignition to two switches and a button.. so the small chip that inhibits it to start is still on the ignition switch

 

poor car

 

Did the dealer ever tell you what they changed to get it running? If its running now that is (hope so!)
