87' tII , walbro 255,fcd,safc,blitz boost controller,720secondaries,ported wastegate,3"all the way back...Rtek 1.7 on way just need them to ship it back...But my question is sometimes my car will start other times it will start up hit like 1300rpm and die out and sumtimes it just cranks it seems like a fuel issue...Should i just wait to get the rtek and that will fix the problem ...or what all fuses etc look fine.

cls6888

I just went out there to check it again all it did was crank and crank and crank...
When i walked by the engine bay I can smell fuel and from the tailpipe...Another weird thing that is happening is im not getting my music to play through my speakers.....dunno if that has anything at all to do with it or not. could a short or sumthing be causing this...Im clueless

cls6888

Im hoping its just flooded...How exactly do I go about unflooding it i searched and got a idea but still not 100%...i pulled the egi comp fuse cranked it for like 10seconds then put it back and tryed starting it.. nothing. Am I forgetting to do something??

cls6888

For some reason i think my ecu is fried?????

cls6888

its defiantly not flooded...i tested the trailing coil and im not getting any spark or anything...Do yo uthink its possible for it to be a ecu problem?

MistaBaloo

damn hommie............

cls6888

thanx for the usefull information ^

MistaBaloo

sry i was just referring to the amount of posts....but if i remeber correctly i am having the same prob did you, push the gas all the way to the floor as you tried cranking it with the egi off...that helped for me..

What makes you think that? Did you pull your spark plugs and find that they were BONE dry?

How did you test the trailing coil?

Anything is possible. However its far more likely that your car is flooded.

Now, you said you searched (and probably did.....a little) but in your search of the thousands of threads regarding flooded engines, did you happen upon the tidbit of info regarding the film of oil on the apex seals and its relation to compression?

When you flood the motor to extreme (almost garuntee you thats what happened) the oil film on the seals washes away and compression drops greatly. This is why pulling the EGI fuse and cranking the motor did not start it. Because even though you starved the motor for long enough to presumably start it, the oil film was gone and therefore compression wasn't high enough to create a big ol' firing.

Pull your leading spark plugs and drip a couple drips of MMO in there, crank it over a few times with the EGI fuse out (and plugs out) then a couple more drips of MMO,put the fuse in - crank it and cross your fingers.

cls6888

ok ill give that a try tomorrow morning and let you know

cls6888

do i pull the egi inj. fuse...?

classicauto

iTrader: (3)

yes

also bear in mind that most flooding problems are due to lower base compression in the engine as well as leaky/sticky injectors.

Meaning you may the get car running and want to check those things out *nudge.

cls6888

well would having the 720secondaries/larger fuel pump and no rtek(on way once the ship the damn thing back) possibly cause this also?

-And what is MMO...?

cls6888

Ok well i just pulled my leading plugs and there was gas on them....I also compression checkd and it was about 93-96 front and back... so now im going to try unflooding it by using a little bit of MMO etc. I just wish i knew what was causing it to flood if that infact is the problem...

"Pull your leading spark plugs and drip a couple drips of MMO in there, crank it over a few times with the EGI fuse out (and plugs out) then a couple more drips of MMO,put the fuse in - crank it and cross your fingers."

-when i crank it to try and start it I put the plugs back in correct along with the fuse...

is it possible that I may have shorted out/blew my leading coil when i tried to ground it...??? if so would it cause the car not to start or run weird..?

cls6888

well i did this^ and it almost started "so it seemed" puff of smoke out of tailpipe sounded like it wanted to start then didnt...after that all i could get was more cranking...:-\ it just seems like to me its not getting enough spark or something is it possible my leading coil ended up frying ... and would that cause it to not start?? i think i may have shorted the leading coil out awhile back after i tried grounding it....

Well, the motor does run better when the plugs are in it.

Now:

its possible your leading coil is fried yes.


However its MUCH MUCH MUCH more likely that the car is flooded again.

And as stated before the reasons for frequent flooding are (however aren't exclusive to):

Compression
Leaky/sticky injectors

Now, you put 720 secondaries in? how old are the primaries? (and no, that wouldn't cause this problem, secondaries don't open during cranking, unless for some reason you the only pair of brand new inectors that are stuck open and constantly pouring fuel in)

93-96psi as a peak reading is good....however I would consider anything below 90 to be on its last legs. So you're motor is on the border line.

When I add up these things, low compression, unknown injector age/condition they all equal a difficult starting, frequent flooding setup.

Thats what you've got - the only way to cure it fully is rebuild the engine and replace the injectors......among a few other little things.

For now I would suggest installing a fuel cut switch (will act like pulling the EGI fuse) and when you try to start the car, leave the switch off for a few cranks, then flip it on. And when you shut the car off, turn the switch off, let the pressure bleed down, then turn the key off.

This will bandaid your problem. Good luck.

Trust me its the problem.....and what is causing it has been said.

cls6888

Well i cant unflood it...

classicauto

iTrader: (3)

Did you try the fuel pump switch trick?

cls6888

what is that...?

ive pulled my plugs and everything i cant unflood it for my life...

cls6888

this is my plan....going to junkyard getting a new leading coil,my ecu arrives in 5 days or so ill install both and pray for the besssst. I am not getting any spark of any kind from my leading coil so i think i fried it or the ecu

~Rev Free~

its exactly like my problem, near same mods also. you got aim? problem with mine still hasnt been resolved, need to reman injectors or just get new ones.

btw, any one got a write up how to remove the intake manifold, grrr. thing wont come off.

cls6888

well i FIXED HER!!!!!!!!!!!!!!! it was the leading ignition coil like i thought i went to the salvage yard and picked a full assembly up for 50$ put her in started right up and ran great :-)
