Default My swapped car wont start...

Well this is killing me,

The Car cranks and i hear the fuel pump after i stop cranking it sound louder than it used too.

The Cars is an EJ22T with EJ25 Heads, The rails, regulator and injectors are Stock WRX, The Fuel pump is from an STI, Is there any problems there?

I checked for spark at the coil, it was there, Checked for spark at the end of the wires it was there, I replaced plugs, Nothing.

I pulled off the Fuel pressure regualtor line gently for just fuel to start seeping out, So there fuel there, Did the same thing with the return line on the Fuel filter, There was fuel there!

What can i do to check for fuel pressure?

I used a Stesascope to hear if my injectors were cycling only could fit it good on front right injector i only heard a few small clicks,

What should it sound like?

So my car is getting Spark, It getting fuel (maybe not enough pressure to open injectors) I dont smell any fuel in the engine bay, The car only cranks it has not even studdered or even fired, I made shure i wired the injectors correctly (double checking tonight)

So what do you guys think?

Throw anything out there all help is greatly appreciated!

Just noticed the injectors are sealing properly and everything, But the connectors are all going diffrent directions, not opposite just all funky directions does this matter?

Make sure the feed and return lines are straight. I just finished my swap and the hard lines on the WRX 2.0L were backwards compared to the STI motor I installed.

I believe Early WRX, the hardlines are the same as stock. But the Soft lines were modded i know the fueling works because i saw the moter, running and working in a car before i bought it, So From my fuel filter it goes to the regulater, The reglator then splits into a T which im assuming supplies fuel to both rails, The rest i assumed were return lines, Is it possible i mixed up an EVAP with a REturn would this make the car not start at all?

The moter this came out of was a 98RS, Before the FPR there was T spliting into 2 lines, i assumed this was RS specific so i removed the T line and just feed it the one line from the fuel filter.

Alright i fixed the fuel lines which to say the least were all wrong, Its trying to fire but i wont its getting ignition, But what does it sound like when the fuel pump is bad mine sounds all gravely and sounds like it just rockets one big amount of gas to the engine and thats it.

what ECU? AFAIK the cam sensors are pretty different on a 98RS to a 94 tleg (assuming this is the car in your profile....since you didn't say ). if you're trying to run that hybrid motor on the stock ECU it might try to run, but I highly doubt it'll run right.

Stock ECU for now, The Cam gear sensors and crank shaft sensors were identical to mine they were broken so i replaced them with my stock ones.

Yes it is an EJ22T block with EJ25 heads (SOHC) i dont see a problem there

well, I've been looking at some of these motors. for example, the cam sensors are interchangeable between a '92 legacy EJ22e and a '96 impreza EJ22e. but they're mounted in a different place, so will be programmed differently.



also, 2-minute bumps aren't going to encourage responses.

so if it hasn't started yet, one way to check a fuel pump is go to napa or shucks. Buy a fuel pressure tester. A fuel pressure tester is an in line pressure tester that goes between the fuel rail and the rubber hose via hose and clamps. Install tester. Key on Engine off tester should show pressure. to little or none at all is bad. This is also a way to check the regulator.

You need the crank + cam pulley ( the one that goes with the cam sensor only ) That goes with the Ecu you are using... othe wise it will NEVER EVER start and idle....

From what i understand you are using a ecu that was using a single cam engine and you have put twin cam head? 99% sure thats your problem

Now try putting the crank pulley of your stock engine on your built

And do a Trigger whee on the cam sensor pullerl with the same patern of your stock one...

BUT it wont probably start anyway if you are using a STOCK single cam ECU as fire order and injection order are very different

You need engine manegement thats goes with those heads
just my tought... Hope that's help
