R33 Gtst Suddenly Died, Won't Start

[lego]

Hey all,

I've got another issue with my 96 gtst.

Driving along today on about 70k's, aircon on (32 degrees outside), changed to an 80k zone so I go to speed up a little.

All of a sudden I can feel the car rev, but the tacho didn't move. I backed off and tried again. Same thing, but the hicas light came on. Then I lost power steering. The whole dash lit up, all warning lights came on. As I pulled over, she stalled.

I let it sit for 10-15 minutes, tried cranking her over, she would start and idle rough as hell ~450 rpm then stall again. She did that about 3 times but now won't start at all!

Bog stock apart from an exhaust.

2 weeks ago I put a new fuel pump in.

Replaced the fuel filter.

Replaced all spark plugs.

Cleaned the afm.

Checked over all coil pack and the loom - all in mint condition.

I've checked all fuses, nothing is blown, all the relays are good...

I'm stumped!

Anyone else have this happen??

[Badgaz]

that sucks dude, i'd start checking the basics...check fuel pump is pumping fuel, check spark....if they are good try a different airflow meter...you might have a broken one.

[Kane_R32]

CAS or AFM I reckon...

Sounds like the fuel pump you replaced is having issues, pull off the fuel hose and feed it into a bucket or bottle and flick the car "ON" however don't crank it. It should prime, see if there's any fuel first.

Then work from there

I didn't check by pulling the hose off, but after letting it sit for an hour or so yesterday, I flicked it to 'on' and I could hear the relay click and the pump prime (noisy walbro). I'll pull the hose tonight after work and check for flow.

Will post the results later.

Check ecu for fault codes.

[skyline1000]

could be anything...loose or cracked vacuum hose, bad maf, bad o2 sensor, loose electrical connection, poor sensor ground, or faulty cam position sensor. Those are the main things that will cause a car to run erratic.

No fuel pressure. Again.

Took the line off the manifold, turned accessories on and nothing. Thought it might have been the filter, so I took that off and still nothing!!

I've tried swapping relays around, tried other fuses but no joy.

This thing is doing my head in...

[Dose Pipe Sutututu]

Fuel pump would be installed incorrectly and hose might have popped off inside the tank, hence you can hear it prime but yet you're getting no fuel pressure.

** edit

OR your FPCM & resistor has carked it.. try earthing your pump directly, bypassing the OEM earth.

1+ to check hoses correctly. I installed my walbro 255 with the supplied hose it blew a hole in it after 2 days same symptoms. The hose they supplied was so crap and so below average

This is the part where I put on my little propeller hat and slink away...

This arvo after pulling a fuel line, I run a multimeter over the fuel pump loom and plugs. Good power there. So I pulled out the pump - I should have taken photos, it was so odd - one strand of wire hanging on to the positive wire!! I soldered the joins and heat shrinked them, not knowing heat shrink deteriorates in fuel, but the strangest thing was that it looked like the solder had corroded, it was pitted in spots and missing in others! I know that I had great joins when It went in two weeks ago, so exposed wire and completely covered in solder. Unsure what solder it was as I no longer have the roll...

Has anyone ever seen/heard of this happening??

[Ben C34]

Wow. Never seen that. Cheers for the update and glad you sorted it.

[ARTZ]

ahh thats no good...sounds like you need a new turbo, ecu and injectors mate...

heres a good one >>> http://www.skylinesaustralia.com/forums/topic/440006-300kw-bolton-turbo-setupadaptronic-td06-44mm-tial-750cc-injectorsready-to-go/

[scotty nm35]

lol. Upselling much Artz?

Did you even keep that Tomei pump I sold you? I hope you did...

[ARTZ]

nope...I upgraded to a walbro bro

[Blackkers]

I had this problem in ethanol. The heatshrink was completely missing on one wire and the solder had deteriorated. Ended up using crimps in the end. I usually don't trust crimps for large currents but if you strip about 15mm off each wire and have them overlapping inside the crimp connector then how bad can they be

did you use chemical resistant heat shrink?

I have.. seems "ok" so far LOL

[lego]

Phew! I was starting to think I was going loopy!!!

I did put one tank of 100 octane through her.. but it sat for about 3 days with it in there..

As for the heat shrink, I had ni idea it wasn't fuel safe... do now though!

I'll keep you in mind incase I die again Artz!

100 octane what? What % of ethanol did it have?

[Ben C34]

P100. It is 98 premium with 10% ethanol from United.
