Ok, the supra just flat out died on me last thurs., no sputtering...etc. now I kno the engine isnt getting fuel and I just replaced the pump, and its still not getting fuel and I know the pump is getting power. Does anyone have any help for me or maybe a full diagram of the fuel lines? Im completely lost now.

Don't know if there are two. The fuel pump has a filter/sock on it, and then there will be the normal fuel filter probably in the engine bay someplace ( no idea where on a Supra, haven't looked for it yet )

So, if your filter is clean, pump is new, have you actually tested for power at the pump? Maybe the relay is toast?

Well theres a cylnder with a banjo bolt and looks the exactly the same as a fuel filter with fuel lines going to it, someone else told me about it and they said they have replaced it before. and they showed it to me on mine. but now im getting even more confused now.

If you're talking about the thing bolted to the intake side engine mount it's just a Union there's nothing inside it.

Ok, om glad you told me that before I went and took my mani. apart. Maybe you can help me find my prob. then, Last thursday the supra completely cut out and died on me, and I can tell its not getting fuel to the engine, I thought it was the pump so i got a Walbro and got that installed and its still not getting fuel, and i know the pumps running. So could it be my FPR? Ive also checked all my fuses etc.

Start by doing a visual on the lines and make sure none have been crimped shut.

Someone here had badly blocked lines recently so that would be the next thing I'd check.

thats what I thought at first, but the line that is on the intake manifold side is the return line right? because I pulled that off and cranked the engine and it shoots out off the block side so it seems to me that the FPR is stuck closed possibly? I dont think that the lines could be crimped shut because it was running perfectly fine then the shut off after driving for a good hour straight and wont start at all now.

Ok now I'm confused!

I thought you said the motor wasn't getting fuel?

So it has pressure at the rail?

Check the Injector fuse.

I've already checked every fuse, and maybe a little more info. would help, It was hard to start for a few days but still running fine, so i thought my starter was starting to go out because it was still running strong, but then on thurs. ( few days later) the car completely dies after an hour or so of driving and then wont start from then on, and after inspecting I realized it wasnt getting fuel anymore, so I replaced the pump and its still doing the same thing, oh and the fuel filter is new too.

What is it that you did that you feel sure the engine is not getting fuel?

Because after cranking for a while if you smell under the hood you can smell the fuel from the starter injector. Plus the engine is cranking fine, and my alternator, plugs, wires, coil.. etc. are all new

Cranking can you hear the injectors firing?

Haven't checked that, Ive had to work on it by myself today, so I didnt have someone to crank it for me
