Check the voltage at the pump.

I had an issue with my walbro (well it wasnt the walbro actually, read on), did what you did. Pulled it out, tested it on the bench, worked fine. ECU was switching it on in the runtime values, but the pump wasnt firing.

Ended up being that the pump was only receiving 11v for some still unknown reason. Wanted exactly 12v, or more. No idea why.

And if youv ever tried to track down a voltage leak, you will know not to bother and just re-wire. So thats what i did, off the unused 4wd 12v lol.

The other problem however, some good advice! Nothing more to add.

Well ,put in a oem pump back in the tank, changed the plugs and eventually got her to start back up and idling again. Got carb spray and sprayed around runner 2 and the idle changes, and the car fills the garage with smoke

So I've found the problem.....Just to fixit now :cheers:

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
