I Need Help!!! // Find Me Grounds

[92acclude]

Right

The car: 92 ex, JDM H22A, M2B4, P13, hacked wireharness

Here's the problem. My car won't start properly. The fuel pump doesn't prime when you start the car. The fuel pump is a new Walboro 195lph unit. The main relay is a year old and works. I tested the old relay that was in my car, and it was working as well, so that wasn't the problem. So all that leaves is grounds.

Prior to starting there is no current going to the fuel pump, but after the car fires, the fuel pump receives the signal like it should. It only fires after I crank it for 15-20 seconds. After that it runs normally, other than some light surging idle.

So my question is, what grounds should I look for to fix this?
Where are they located?
What else could be the root of this problem?
Should I take a sledgehammer to my car, cause I haven't been able to figure this out for over a year, or am I just retarded and not trying hard enough?
And is there anyone local to CT that wants to come up and try to fix this?

Thanks guys.

your whole car is a "ground"...

Doesn't the main relay get the fuel pump going?

I realize my entire is a ground, it's made of that substance called "steel".

Travis, thanks for the link, might be it, haven't finished reading it.

Yes, the main relay does start the fuel pump. Something is preventing it from doing this. I don't know what, and that is what I need to figure out.


FTW!!!

just because its steel dose not mean its a ground tool

[92acclude]

Yea I know, lets drop it.

[turboaccordlx]

okay.. trying to figure out what your doing here. . . why do you need to use the factory ground to get this to work?

[92acclude]

I'm moreso trying to figure out what could be causing the problem. Once I eliminate those possibilities then I can go from there. But its not like I can do that being stuck at work. I just haven't been able to figure out what grounds could be missing.

Though the link that travis posted up has tons of stuff that I need to check. Woot.

hope that helps

fuel pump should turn on for 2 seconds with KOEO. If not, then you may have a problem with your PCM, if you say your main relay is Ok.

I'd go with Question 5.

[92acclude]

What me being retarded?

Yeeeeeaaaa, that's a default.



And I love diagrams, thanks. What's the PCM? (holy noob question)

Since your main relay tested fine and fuel pump is supposedly fine, you also said your fuel pump receives no power. Based off this, I'd say your problem lies before the fuel pump and before the main relay.

You also said it takes a 15-20 sec to get the car to fire, then it runs afterwards. The inidication it runs afterwards, leads me to say that the "run" portion of it is fine for most part. I think your problem is in the "start" system of your car. I'd look into things like the ignition switch and clutch switch. Look on that end of the system and see what you find and report back.

One more thing I should mention, when I turn the key to start I, the check engine light comes on and stays on. Also when I start the car for the first time each day, I can crank it to the point when the relay flips and turns the pump on. I can hear this and stop cranking while the pump primes, and then it starts up fine.

dude, your guessing in the air.

take out that area and test to see if its getting voltage, and see if its getting good resistance to ground.

if there is no voltage check voltage at the main relay, if there is voltage there back track and find where there is a break...sometimes people use butt connectors and those fail.
