i have 94 del sol, b16 swap with t3/t4 turbo setup on 5psi.
so heres my problem, sorry i tend to say a lot but im trying to get all needed information in. my car usually will not start unless i push start it and now its getting to the point it doesnt even want to start when i push start it and if it does it runs really rough and i have to keep my foot on the gas for a while and it will start to idle on its own. it wont throw any codes unless i crank it for a while it throws code 4 which is crankshaft position sensor, it used to throw top dead center sensor but now it shows this one. when it starts the cel will turn on after running for a minute and throws the same code and the ecu goes into limp mode. ive tested for spark and it is getting spark after i crank it for a second, its getting good fuel pressure at the fuel filter, 45 psi at idle and 52 at WOT, i did a compression test and i got 150 all across. cams point straight up when the harmonic balancer is lined up with red mark(tdc). im stumped and have no idea what else it could be, i am a noobe and this is my first honda and ive only had it for a little over a month.

i have replaced the distributor twice and now it has a msd distributor with a blaster coil, msd 8.5 wires, ngk plugs, engine temp sensor, fuel filter, aem fuel pressure regulator due to humming noise.
any info would be helpful, thanks!!

 

have you checked vacuum pressure/leaks? Try another ecu? just a guess iv never owned a turbo......Bump.

 

i havent checked that yet and i dont have another ecu to throw in it right now either. is there anyway to get a ecu tested?

 

You can get it tested out. Check Xenocron.com. Chris is good at what he does. I believe it is under services on their website.

 

do you have bigger injectors? a base map? was it running before then it stopped?

 

on some motors there is a small black wire the plugs into the block. It's on the left side of the motor under the distributer. That's what happened on my old b16 that I blew up. wouldn't start with the key at all. Those tend to come unplugged/loose if you hit a bump. check that out. Also its always good to push push start a car it can mess up some ****. Hope this helps.

 

i just barely bought the car and ya it has the blue top injectors i believe there 450cc or something and it was running fine before.
