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??

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.

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...

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.

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??

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

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?

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
