Red Top SR20DET Issues - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have the SR in a 510 and I'm having some issues. The car was running perfect last night. I got in the car to drive to work this morning and I ran into some issues. I let the car warm up for 5 min before driving. Once about a mile down the road from my house the car started to sputter at very low RPM's. I'm talking 1000-1500. I was able to limp it home while it stalled on my twice and parked it in the garage.

When I got home I checked for any loose wires, sensors, couplers, etc. Nothing seemed out of the ordinary. I started the car up and it was fine. Let it idle for about 1 min and took it down the street for a test drive. The car ran fine. I was able to get it through 2nd gear in full boost. About 2 miles in this time it started to do the same thing and sputter at super low RPM.

Got it back in the garage and checked for Codes. Its throwing 55 which is nothing. I tightened down some couplers that I thought could be a little lose and tried to drive it again and it just sputtered the whole time. After this time of it dying out the car will not start back up now. It will crank but not start.

Everything is stock on the engine besides I do have a HKS BOV that is recirculated. I have a top mount manifold for the T25 (clearance issues in the 510). full 3 in exhaust, FMIC, Manual boost controller set to 9LBS.

I have searched and searched over and over again and can not come up with any reasons for the issue. Everything I read is posts of things to check then the original poster does not respond back to what fixed the issue. Any help would be great. Thanks.

Coilpacks check and see if ur fuel pump primes my fuel pump died did the same thing

First thing I would check is battery, it could have dropped a cell or something. So check amps and volts across the terminals.

Also check fuel pump,coil packs, injectors and timing.

The pump is priming, but I do think its something with fuel. I need to get a fuel pressure gauge to check where I'm at. What should it be? I'm running a z31 turbo pump.

What is the process to check the injectors and coil packs?

Some pics of the car

Probly fuel pressure or bad igniter chip probably over heating

So today I check for fuel pressure. Although I do not have a gauge to check I was able to determine I'm not getting enough fuel. I took my return line off and hooked up another hose and ran it to a gas can. After starting the car and getting it to idle no fuel was coming out the return line. So just to make sure it was the pump and not a clogged filter I by passed the filter and I still have no fuel returning.

I would assume based on this test the pump is not putting out enough pressure and what little it is supplying is going through the injectors enough to get it to barley run. If anyone has any other thoughts let me know.
