#4919, "Motor back in - car won't start .... fuel problem"
If you look down a thread or two you'll see I posted a while back about pulling my motor. I finally have the whole thing rebuilt, back in the car, squeezed in a wedding, and now I have all the accessories hooked up. Problem is it won't start now. It turns over, but it won't fire. I believe I'm not getting any fuel. I ran a light tester to the fuel pump and it's getting power, but it doesn't sound like it's priming to me. Did I forget to hook something up or did my fuel take a dump on me? It seems really odd to me that the fuel pump would just die while the car was sitting. Any thought suggestions appreciated. Oh, car has 47k on it in case you're wondering how used the fuel pump is.

that is quite strange. did you make sure you hooked up all the sensors while installing the motor? and you said you dont hear it primeing? i dont know if yours is a 2g guessing by the picture im hoping but in my 1g you can hear it priming. im guessing the fuel pump is shot would be my 2nd guess after the sensors and wires. it may be strange but your pump could have for some reason gone even though you have low miles.. just double check everything in the install and i would try the fuel pump. everytime ive had a fuel problem in all my cars its been the fuel pump so i dont know lol.

I had the same problem when I put my motor back in.
If you upgraded your pump and have an AFPR, have someone crank it and watch the gauge, stock turbo fuel pressure is 43psi.
If you rewired it, double check all your connections and make sure you grounded it to a suitable place, if you grounded it to where the fuel pump cover screws into, it wont ground there since there is plastic things in there. If you take off your back speaker panel, you'll see a bracket where the panel screws into, I grounded mine onto there and it works just fine.
Another thing to check is if you rewired it, I know this is dumb but I've read quite a few posts of people who forget, make sure you have the fuse in the fuse holder for the fuel pump and make sure its not blown.
lol Again if you re-wired the fuel pump without soldering it, I highly suggest soldering it, I didn't solder my SAFC connections and they didn't work but as soon as I soldered them, bam it worked, same thing happened with the fuel pump.
If you don't have a upgraded pump and/or AFPR I can't help ya out there. Maybe make sure your 20A engine fuse is in? lol

I forgot to mention that I did check to see if I had fuel at the rail and I don't. I didn't put in a new pump or rewire anything. I left the fuel completely stock for the time being. I was just reworking the motor. I have plans in the future to upgrade pump and injectors, but not at this time. I talked to a mechanic last night and he said to check all my grounds. He said if something is not grounded correctly the computer may block the signal to the pump, thus not allowing it to start. So, I dunno, I need to double check wiring conenctions and whatnot. I might try taking the pump out and giving it a little tap too.
Oh ... and yes my car is a 2G. The pic is actually of my 420A, but my 4G63 looks identical. If you didn't know me well you might not even know I got a different car.

Before you go searching all over for grounds and breaks. Check to see if you got power at the pump. Sounds kinda simple but sometimes we get caught up and forget the simple stuff.

I figured out what is wrong ... and it's not good unfortunately. I ran jumper cable from the battery to the fuel pump in the back of the car and it primed several times. So, I was at loss as to why the pump wouldn't prime with the key. So, in a desperate attempt I plugged in my code reader. I wasn't sure if I would get any readings since the car hadn't run, but sure enough I got one code = The crank position sensor. Appearantly that thing took a dump on me, which if the ECU doesn't see the crank position it won't tell the pump to prime (I found this out after a bit of research). So, I orded a new crank position sensor yesterday and Mitsu called me already this morning to say it was in, but the problem is to get to it and install well I think I'm going to have take the motor back out b/c it's under the timing cover and behind the timing belt. Sucks.....

Well .... if you my post above this one you'll see I figured out it was the crank position sensor. So after ordering a new one and taking everything back apart I figured out I did the dumbest thing ever. I installed the original one up-side-down. So, I didn't even need a new one. When it's installed correctly it reads the crank positioning sensor blade (on the crank). Oh well. Alot of work for a stupid mistake. At least it wasn't expensive. So, after all that, the car started right up. Duh!

AND... you have a new spare CAS.
