Ran Out Of Gas, Now Car Wont Start

First of all I have a S1 RB25DET in a 89 S13.

I was tinkering with it the other day then suddenly, it started to stumble and die. My gas light was on and the gas level was so low that it got stuck on the plastic cover. So I automatically assumed that I ran out of gas. No big deal.

I let it sit for a few days before trying to start it again. Now today, I filled maybe 2.5 gallons of gas into the car. As I went to start it, it didn't start. I tried numerous times.

Things I know:

- I have spark

- The fuel pump primes on "key on"

- After cranking, I checked plugs 1 and 2 and they were dry. No fuel on them. I was expecting them to be wet and fouled from all of the starting attempts

- The car ran perfectly before it died. I was setting timing and idle and it drove great at that time.

- I pulled the fuel pump out and the sock looked kinda dirty. I also noticed some rust flakes/dirt in the tank.

- The fuel pump and filter are brand new. Is it possible that the fuel pump sock or filter is clogged because I ran the gas so low causing it to pick up dirt at the bottom of the tank?

That's about all that I can think of right now. As I find out more information, I'll notify you guys. Thanks in advance for any help.

not very likely. maybe you just sucked the thing dry.

how much is 2.5 gallons? fill it right up (just in case if your tank can't suck to the bottom.

try and start it a couple more times so that the lines actually get some fuel in them. you should be right. i've done it a few times on various cars and they all recovered.

2.5 gallons is 9.46 liters. Sorry I'm from the US.

I've tried starting it lots of times. Maybe too many times at this point. My fuel pump was submerged in fuel when I pulled it out. I'm pretty positive that I'm lacking fuel and or fuel pressure. I don't smell fuel at all during cranking and the plugs stay dry. I'll have to check my fuel pressure to confirm this.

When you say the fuel filter is brand new, do you mean before or after you ran out of fuel? I would change it you have probably clogged it suckign the crap out of the bottom of the tank. wierd that you are not getting any fuel though

The fuel filter was new before I ran out of gas.

I just realized that I might have another issue. I didn't have my fans on when I was setting timing and my idle speeds. And I think I remembered seeing my water temp gauge hit "H". So I'm sure I was overheating and running out of fuel at the same time. I had the car idling at the time. Can overheating at idle cause my car not to start? I didn't notice any audible knock, boiling coolant, or anything out of the ordinary.

well start with a new filter.

Its very unlikely you cooked the motor causing to not start, not impossible but you would have to be pretty unlucky.

Remember all you need to start the motor is fuel, spark and compression......unlikely to be compression but you can always test it.

Found the problem!

First I checked to see if I had fuel coming out of the feed and return lines off of the rail using the bottle and prime method. It turned out that I did have fuel going to the rail. But I swore that I wasn't getting fuel to the engine. So I disconnected the CAS to disable ignition and tried to start the car. I did this to see if my pugs would get soaked in fuel or not. Sure enough, there were dry. So right then and there I knew my problem was in the injectors. I originally bought the car as an unfinished project and I had to redo the wiring because I wasn't comfortable with crimp connections that the original owner used. I double checked my injector circuit and I found that there was an open in the injector power source (grey wire) where the original owner used a splice crimp thingy. So I closed the connection and bam she fired. So I guess I did run out of gas after all. Thanks for those who helped.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
