ok,, so heres the story..

just got finished with my JDM front end. had the HID's wired up. they were plug and play, so no biggie... i go to wire up the fogs, with no fog light switch, so i figure, hey ima wire them into the parking lights from the USDM front end. so i did, and they worked. well, i aim the headlights, and turn on the fogs, and notice that my gauge cluster lights are out, so i figure, no biggie, i prolly just blew a fuse,. ill check it in a min. i was excited, so i figured id take the car around the block real quick. i get onto a deserted street on my block, and proceed to smash. i start in second, pull it up to about 6500-7k, (thats what it looked like, with no cluster lights) and short shift into 3rd. i get into 3rd, and right when i hit the gas, it bogs.... BAD. i see my oil light come on, and so i kill the motor, and coast. headlights and fogs still on. when i come to a stop, i turn off the headlights and just have the fogs on. i try to start it once. it doesnt. so i push it back to my place..

get home, and pull the plugs, thinking one may have fouled. i pull them and notice cylinders 1 and 2 are almost FULL of fuel. so i proceed to crank the motor, shooting the fuel out. i think i may have siezed my injectors open, since i was tuned on 290 cc injectors. which were too small and were almost maxed out. so i get another set, and figure out whats up with my cluster lights. blown fuse. replaced it and rewired my fogs, so they arent on till i get a switch.

so i go to start it, with new injectors. and the motor turns over like twice, then it just stops. like the starter doesnt have enough torque to turn the motor. so i pull the plugs again, and 1 and 2 are full again! help.

timing belt and cams are ok, dizzy is ok, all of the pistons are still at the correct level. i have forged CP pistons and eagle rods.. so im thinking the pistons try to compress the fuel, and cant, so it puts a load on my starter, and it stops cranking.

my question is, do you think it could be an electrical issue?? bad ECU? ground?? relay problem?? im tuned on hondata, and a chipped P28.

cliffs:

jdm front completed, i go for victory ride, and im become not so victorious... but the motor floods in 1 and 2. and now i dont know what the hell i m doing. electrical is not my bag baby..

 

Why not check if you have spark in those 2 cyl.

 

yea that what he said.

 

oh yeah, my bad, it still has spark in all 4 cylinders..

 

you may have done more damage than you think


if the starter can't turn it over because its trying to compress fuel, the motor have have already done it when it cut out, ie hydrolocking it with fuel. something to think about anyway, electricals aren't my bag either

 

yeah, thats what i was thinking.. but i can manually turn the crank with a rachet... so im hoping its not locked up

oh, and without plugs in it, it cranks over just fine

 

Double check your wireing to make sure the common ground on the injectors didn't get messed with. Look in the HELMS for complete wireing diagrams, see if you can trace the injector circuits to anything that you may have touched during your front end installation.

I would also try another ECU to see if the problem exists there.

Sounds more or less like an electrical issue.

In terms of what damage could have been done, you could have hydrolocked your car, could have washed your rings as well. Try and do a compression test if the motor will allow, that will tell you if your rings are intact.

Good luck.

 

can you unflood it, pull the 4 injector pigtails off and will it crank over?

 

Your fog lights need to be wired up to a relay to get the proper amount of power. Thats why you blew a fuse. As for the motor, is this the first time you've cranked it over since it was put together or just since you've put on your JDM front end?

just the first time since i put the front end on. the motor has been perfect for 5k miles now

Dude, why are you ignoring me,

Send me the tracking

 

I would guess a shorted set of wires for those two injectors going back to the ECU, look for a harness rub, does your harness go under the intake, is there an intake braket to help carry its weight down to the back of the block or maybe a short to ground going through the firewall?

Pull the ECU and give it a smell just in case.

 

I had the same problem, my car was flooding in numerous cylinders. I thought about it and came to the conclusion that it can only be a few things. ECU, stuck injectors or minor wiring connecting to both ecu and injectors. I changed the injectors, and the ecu. Car stopped flooding. Then i had another problem, car would still foul out plugs though, linked that to spark. U stated that you are getting spark but how strong is it? I changed wires, plugs and rotor. now car runs perfect. This is my experience hopefully it willl help. Good Luck

 

good luck

 

Sucks i been there were my car wont start. Mine my car got flooded with fuel and all i had to do is put my gas pedal all the way to the floor and then turn the key and it started right up.

But if you need another ITR ECU to use to test. I'm more and willing to let you use mine. Since i do live in the same area.

 

First test is swap injectors to different cylinders, IF the problem follows the injector you have bad injectors. If the problem stays witht eh cylinder, double check spark. If you have good spark, the only problems left are either wiring or damaged injector drivers in the ecu. Try swapping a known good ecu and if the problem persists, it is a wiring problem and you need to trace the wires from injector back to the ecu and the power distribution block.

 

same thing i said

 

If you could get some small terminals, not sure what your injector set up is, you can bypass the injector wiring on those two and splice into the wiring near the ECU to install new wiring as a last resort, be carefull if this is shielded wiring.

 

well, were good guys, turns out it was the FPR. i guess AEM has had some problems with the diafram, (sp?) and mine had a rip in it. it was just sending all the gas that was supposed to go into the return line, back into the intake mani, thru the fpr vacuum hose.. shes up and alive again. thanks for your help guys

thx to brewcity too

 

post some pictures up now!

 

lemme get the front end painted first.lol

 

So I take it that the vacuum hose went to that end of the intake manifold, that was a huge diaphram leak. I know the FPR can make a car rich but damn.
