BHG. Caused by taking your cat off.

You could always order a new connector and keep the stock sender for ECU use only. There's other pressure ports on the block.

Wtf? All of that is just plain wrong. OP: You can do without the stock sender. It's for idle control and the effects are minor.

Crack me up...

Yeah, that's strange...

The integral feedback pot is worn causing the system to chatter in open loop. Good luck with that. The servo is around $500 and may not even be available. Plus the job requires dash removal.

Sure, wealthy and happy mechanics are as common as dirt. He should go to dealerships and ask them, especially the 40+ year old ones...

It never ends...

I can ride fine. With what was a leg busted in three places along with a badly compressed ankle it's the walking any distance part that's a little tough. It would have killed an ordinary man :icon_razz

Thanks Jon. I knew about the diode but been so long I wasn't sure how it's connected. Not near my books. Truth is I thought it didn't isolate E1. Ah well. Kind of hard to believe he'd miss those wires but we'll see.

By prime I meant supplying an alternate source of fuel using ether, the cold start injector, or just injecting it into the induction system. As for codes, not sure if serious. I thought you had manuals?

That's a crap load of text without saying much about basic troubleshooting. Spark? Fuel? Will it run if primed? Assuming a stock ECU codes are easy to check even if the diag box is missing. Still sounds like valve and/or ignition timing though. As for what the stock configuration looks like...

Make sure the injector grounds (white/black) on the manifold are connected. 12 vdc at the ECU is normal when the drivers are off...

Funny how the stock regulator's ability to hold pressure has no negative effects...

Primum non nocere....

Again, if the check engine light does not come on when the key is switched on (past accessory but before the start position) odds are the ECU is not receiving power. That can be caused by the IGN fuse or EFI fuse, among other things.

Huh. I'd have thought that would be child's play for a mechanic of your self-professed caliber...

The radio has nothing to do with the 7.5 ING fuse. It does have something to do with the 7.5 Radio fuse though. Neither have anything to do with cranking. Since we're apparently supposed to guess what "I can't get any diag codes to work" means I'll give it a shot: if the MIL doesn't come on with...

Lose the Haynes and use this: http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=038

Doesn't matter. Without the cover you're screwed...
