fuel issues ( no pressure at fuel rail)

[mattsplat72]

I am trying to find the location of the fuel pressure control VSV. I Am not getting any pressure at the rail.

No codes, Pump good, COR relay good, FPR good, Lines are not pinched. Pump comes on with ignition and with diag block jumped . So I checked the TSRM and the VSV seems to be the last thing to check...

If and I mean if I switched the connection of the soft lines at the tank . ( the return line and the line going to the charcoal canister would that cause no pressure) if it is that I am not going to tell you guys....LOL

I would definitely double check your lines to make sure you don't have any pinched. This happened to me a while back on Supra I was rebuilding, I have a hard line from the tank to the fuel filter kinked, caused no pressure in the rail, un-kinked it and worked great. Just saying it happens, I didn't think it was either. Also check your fuel filter to make sure it isn't clogged, doesn't happen often but from what I understand it either flows or it clogs completely so check it.
Good luck

Yeah I am going to change that out tommorow I think I have one sitting in a milk crate

You can try this to make sure fuel is making it to the fuel rail.

^ Not sure what you're getting at but removing the screw doesn't let fuel escape. Since it pops up whenever pressure is present it's still useful though. Course, removing it would defeat that usefulness

Thanks JetJock. I Know for sure that there is no fuel pressure. I poped the fuse cover and turned the ignition to the on position. I lossened the 14mm banjo bolt. No fuel squirt
Nothing nada. I am realizing that it isn't an eletrical issue. I has to be mechanical.. SO today I am going to put the car on four jackstands and start at one end and work my way to the other. Has to be a pinched line some where. While I am at it I am going to replace the Fuel filter. I am thinking that maybe I am not getting the bottom of the fuel pump into the plastic baffel in the tank? Oh and I have half a tank of gas as well so I am sure the in tank fuel level is good.

im not sure if anyone has mentioned this yet, but you should check the "J" tube, make sure its not clogged.

A plugged J-tube would cause over-pressure.
