Mah car won't start :(

[suprra_girl]

Went from fine but crappy cps wiring to swapping in a replacement to refusing to start. Didn't check all cylinders but #1 is sparking well.

Left the car a couple of days and went to start it up again today and it started immediately and died like it ran out of fuel. Starting checking efi system and all checks out well so far. Did an injector plug check and these are the results, is this meter behaviour normal or do I have something wrong there?

The injector is still connected to #4 but not to any others, resister pack bypassed and efi feed only feeding #3 & #4 so shouldn't have interference from others.

Cheers for any insights

You sure the new one is good?

 

[suprra_girl]

Well I guess we can scratch injectors off the list, seems all cyl's are wet so it's obviously poking it in.

I presume so, I tested 3 different ones and all same result :/

 

[IndigoMKII]

Okay so you're getting fuel if you say the cylinders are wet. What about spark? Are the coils receiving the voltage and the signal(ground) to fire?

 

[suprra_girl]

I meant to update earlier, eliminated spark, ecu and cps, all my parts (minus injectors lol) work in our other supra.

Tomorrow (i guess today since it's 2am heh) I will be checking each wire at ecu one by one and all through to see what wire isn't doing what it's supposed to lol

Well, if you went from fine but crappy cps wire to rewired cps but no start, I'd say a frail wire broke during the rewire OR a you rewired incorrectly.

I wonder if there is a DCT 14.

Good thing my mechanical skills aren't the equivalent of your reading skills

I haven't rewired my cps at all, and I don't think I've ever wired anything incorrectly (yet, *touch wood*)

I'm bout to see if later I did something completely stupid, I'm fairly sure however I did remove the rag from my intake But I'll recheck it anyhow heh

 

[suprra_girl]

So, I thought for giggles I'd fp and b+ the fuel pump just to hear it's activity in the tank. Sounds like my pump is siezing >.<
My precious Walbro

Off to get gas for it anyway, tho I swear when I parked it, it had fuel.

*Sad panda*

oh and thankfully, no I didn't leave a rag in the intake

 

[suprra_girl]

I guess I remember wrong, I didn't put gas in the car last time i took it out. Diagnosis, fuel pump dead/dying

Recommendations on new fuel pump please?

 

[Orion ZyGarian]

Always have to keep a 1/4 tank in it! Walbros are quite inexpensive still, so maybe just get another one?

 

[suprra_girl]

Curiously I have the pump very low to the bottom of the tank, and yeah I'm gonna keep $20 fuel in it at all times basically to make sure this doesn't happen again.

Not exactly what I needed to buy coming so close to christmas lol

With the fuel lubing and cooling the pump down I was able to start her up but after bout 10 secs or so the pump would seize and she'd stall again lol. Well, least problem found, time to spruce her up a bit

 

[supraguy@aol]

Congrats on chasing it down.

 

[sous]

get an aeromotive 344

 

[IJ.]

Walbro 400 Suze

 

[suprra_girl]

Hahahha yeah I don't think I need that much fuel Ian

Couldn't find a 344 but I did find a listing for 340. Don't think we can get aeromotive locally but I shall find out.

 

[IJ.]

1x 400 would be perfect for your car Suze
(they're cheap as bro)

 

[suprra_girl]

Ended up buying the aeromotive 340 11141 pump Should be on it's way in a day or 2 then I can start fitting it and car will go mint again

Wonder if I'll need to adjust the fpr for it? I suppose it won't make a difference, 38-40psi is what it's set to, one day I'll get an aftermarket ecu to get it tuned properly lol.
