Help!!! Installed intercooler and now car won't start
 

Hey guys, I just installed an xs power intercooler and lower intercooler pipe on my IX. Went to start the car, it would crank, no start. Tried it a few more times, it seems like it wants to turn over but just doesn't. I thought maybe it was the intercooler causing the problem, so switched back over to stock, same thing happens.

I proceeded to do a boost leak test, no boost leaks detected. I've been searching and trying a few different things but no luck. The car was really low on gas, so I thought maybe because it was sitting on ramps, gas wasn't going to the fuel rail, so I put a gallon of gas in there, still nothing! The car was running perfect until the install. Please, any help would be greatly appreciated.


Edit: Pulled the following codes:

P0340 Camshaft position sensor A
P0113 Intake air temperature sensor 1 circuit high (tested pin 1 on MAF harness gets 5v)
P2228 Barometric pressure circuit low. (tested pin 4 on MAF harness gets 11.5v)

Did you unplug anything electrical and forget to plug it back in? The MAF for example...

throw a little more gas in there if it was really low, one gallon probably isn't helping worth a shot anyways.

I double and triple checked all electrical stuff plugs, unplugged and plugged MAF back in, nothing.

The gas light was on, it is no longer on with the added gallon of gas. I'm assuming there is at least 2-3 gallons in there now. Could the walbro fuel pump have failed all of the sudden as it was trying to syphon gas while on ramps on a low tank?

after you added the fuel did the car crank any different? I would also check your fuses to the fuel pump or possibly the ignition, maybe pull out a spark plug to visually see that the plug is getting fuel?

New licp isn't hitting the starter by chance is it?

It still acted the same. You know, it feels like the car wants to turn over but just doesn't, very similar to when you blow an IC pipe which is what prompted me to do boost leak test. Do you know which fuses those are? or where I can find the labeled fuses?

I'm going to double check that, good point.

LICP isn't hitting the starter.

Pulled 3 codes from ecu:

P0340 Camshaft position sensor A
P0113 Intake air temperature sensor 1 circuit high
P2228 Barometric pressure circuit low.

Maybe these will help us diagnose it. My question is could these codes have been thrown due to multiple times trying to crank the car to start or are these codes actually pointing to reasons why car is not starting?

bump. Anyone?

Tried disconnecting the battery for a little bit?

I disconnected the battery yesterday for about a minute, didn't help.

Try disconnecting the negative terminal for 30-45 minutes, while it's disconnected make sure all tbolts are tightened down, make sure the gas cap is closed all the way, maybe check starter fuse/relay?

Did you check your camshaft position sensor wiring? The IC to TB pipe runs right by them (intake and exhaust cams each have one on an Evo9). Since one of your errors is camshaft sensor related and your car isn't starting, could be that the ECU doesn't know where the cam is and is not firing the spark plugs. I believe the Evo won't run without good cam sensors (in addition to the crank angle sensor, which runs down the opposite side of the engine). Otherwise check all harnesses in the vicinity and make sure you didn't accidentally cut/nick any wires.

If there is no boost leak, the Intercooler and piping did not cause your problem. The codes you are throwing are most likely related to the camshaft position sensor aka cam angle sensor. Check the wiring and sensor. Someone mentioned that it runs right by the upper intercooler on the exhaust side of the head. I bet that got banged up somehow and is causing all of this.

If you want, I can swing by your house as I live in Boynton Beach and can take a look/swap out with the one in my car to see if that fixes it. Good luck.

Man that would be great. If you're free today, I'm off all day.

Sure. I can stop by anytime today. Pm me your phone number and address.

We figured it out!! It was the Cam position sensor. Evolution561 is the man!! I really appreciate you taking the time to come out and help me fix my car. I want to also thank everyone in the Evom community for all their input.

Glad you got it sorted! I did say camshaft position sensor earlier too :D {thumbup}

Glad I can help man. Barneyb, why delete? it may be useful to someone else in the future.

Yup you did as well. I did thank everyone for their input. Thanks again for all your help Rom.

BTW, your car runs really strong for few bolt-ons on 93. I can't wait for you to tune my car this wknd. My cousin might also get a tune by you once he comes down here from Jax.

No problem. Just make sure your wideband is all hooked up.

haha, no worries - I was just messing with you :)

Was it just the wiring (loose connector?), or did the sensor go bad?

Thanks!

S.

his sensor was cracked. It must've gotten banged up somehow.

It was strange because I don't remember hitting it with anything. Oh well, I'm just glad the car is running again.
