In some deep trouble.. or so it seems?

[One Jay Z]

UPDATE: WELL IT WORKS AGAIN! HAHA.. the ecu was bad in case you didnt read my last post.. swapped it for a known working ecu and it runs fine now.. Even getting my old one recapped didnt fix it so i guess its toast.. If anyone has a 1jz ecu they want to sell me let me know.. must be a known working ecu also lol..

If your engine light isn't blinking at all then your ECU isn't getting power or your engine light is burned out.

 

[GrimJack]

I've never disconnected the battery before unhooking the ECU. Mine still works, yours should too, IMO.

Does it still turn over?

 

[Mk3runner]

Could be your ECU...I would open it up and look for leaking capacitors.

and if thats the case Driftmotion does the repair for cheap.

 

[johnathan1]

Try a known working ECU.

 

[Poodles]

sounds like the ECU...

 

[Supra87T]

verify the ecu has voltage. it's ig/sw and e1 on the 7M. i dunno if it's the same for a 1JZ but that's where i would start.

I think your mechanics first instinct was correct. Fuel pump. And yes, a fuel pump will sometimes work intermittently (although not well) when it's on it's way out. Get an inline fuel pressure gauge and check the line pressure, I bet that's the culprit.

when my fuel pump went in my grand am, it would start, idle for a seconnd, die. did this over and over and over.

my fuel pump was going in my VW, would only run if it was 60 out, or cooler.

My pump is going in my bronco, when it gets hot its hard to start

you got shitty fuel pump luck bro

It's your wireing harness. A few broken or about to be broken wires, causing intermitent problem. You took the ecu off and put it back on. Now nothing happens. Your harness probably broke a wire (or some) and now nothing works.

Just my thought... :bigthumb:

Now send me my compensation... :evil2:

Heh, we'll c if that is the actual problem.. If its the wire harness.. OMG im in for some heavy work..

Bump for more ideas when i get my ecu back! Driftmotion is repairing/testing it now.

 

[Doward]

Verify fuel (check the pressure, and verify injectors are getting a signal vai noid lights)

Verify spark (check the plugs and use a spark plug tester)

You have plenty of air around, and the timing hasn't been changed, correct?

If your ECU isn't working, you shouldn't have any fuel injectors getting pulsed NOR any spark.

Correct.

But all of this aside, maybe i can add a little more information to this. For the whole time i had the car it had a little problem that i didn't really notice until i went WOT. It would jitter a lot in boost. Its almost as if it wanted to go, but it wouldn't. Now could this possibly a fuel related problem then? Im still waiting for my ecu to come back from driftmotion, but i MUST know of any possibilities in the meantime as my mechanic is definately frustrated and getting pissed of cause its just sitting there... LET ME KNOW thanks!

 

[ATL88Supra]

sounds like your ECU is fryed

 

[zachm611]

could possibly be crank sensor, sounds exactly like what my friends neon was doing, took it to autozone and they hooked up there scanners and that was it, i installed it for him and no more starting problems or running problems like you described, his dad also thought it was the fuel pump but it was getting fuel.

 

[One Jay Z]

Update.. I have signal from crank sensor and cam sensor. I got spark , power to injectors but i have no ground signal from the ecu to injectors. What is the problem? I already had the ecu recapped (repaired) ... Any help would be appreciated thanks! (The strange thing is that it ran for over 1 hr today.. very smooth and no problems.. then died, couldn't start it back up for more than 1 second after this) ?!?
