Hey guys i just finished putting in the new engine and it won't start, i was just wondering if there's anything i should check to see why it won't start. Any advice would be greatly appreciated.

Installed New streetport engine
New fuel pump - trouble shoot fuel pump and it seems to be working fine
Fuel pressure regulator - does show fuel pressure at 40 psi
single turbo kit - oil line feed and return
waste gate and new manifold
Stand alone ECU - Power FC was used on another car before, plug in and the commander lite up so i was hoping that it is working ok.

Check fuel seems to have fuel, flooded two sets of spark plugs.

check to see if theres power on the injector plugs with the amp reader but it didn't show anything the needle didn't jump but when i look at the commander it does show that the injector cycles are working, it start out at 0 and jump to like 12-14%. So does this mean that the ECU is reading it and sending signal but the plugs are bad or the wire might not be plugging in all the way or something?

So this is what i check and did so far so what can i do guys i really want to get this car up and running before snow comes

Note the engine does crank but won't start.

Should i check to see if the spark plugs sparks

Are your crank sensors hooked up correctly?
Are your fuel lines hooked up correctly?
Are your injectors connected correctly?
Is your MAP sensor connected and functioning properly?

yes, you should definitely check for spark. If you're checking with the plugs removed, be careful not to ignite any of the fuel mist that gets blown out of the engine while the engine is cranking. The safest is to put some old plugs in the engine and check the ones that you actually plan to use.

I hope that the crank sensor is hooked up correctly if it's not then it shouldn't crank at all right? well as of right now it is cranking so i hope that it is hooked up correctly

i hope so but i'll check that again, spend about 2 hours on it and hooked it up to a fuel pressure regulator and its working but is there a direction or a book to show you how to hook up the lines correctly by any chance?

My injectors should be hooked up correctly, i mean it shouldn't be that hard right but i'll switch them around to see and again is there like a place in this forum to show you how to do all these correctly?

MAP sensor? where is this located i have to check it out.

but thanks and i'll try it to see.

There are two crank sensors, they determine the crank position and the engine will still crank even if they're switched. One connector is white and one is grey. A common mistake is to switch those two. Check the colors and positions per shop manual. Download a shop manual if you don't have one. Do a search here, you'll find a link. The fuel system gets fed through the primaries, then the secondaries and the fuel pressure regulator is at the end of the circuit before the fuel hits the return hose and back to the tank. If you don't know which is which, remove both lines and turn the key for a SPLIT second, which will cause fuel to squirt out the hose momentarily. DON'T LEAVE THE KEY ON as you'll get fuel all over the engine!!!. The line from which fuel comes out is your feed line. Follow the lines/hoses on top of the engine block and make sure the fuel is routed properly. The MAP sensor takes its vacuum/boost reading via a hose at the back of the throttle body, behind the TPS and the MAP sensor itself is attached to the firewall in that general area. It's a little black box clipped onto a small bracket. First of all, make sure the hose is even plugged in.

I've just had the same problem too . After checking all the things listed by others try putting in some atf or engine oil in the leading spark plug holes . It worked for me even though i had to do it a couple of times after switching off the engine. That's because the new parts will take some time to settle and run in properly. If the engine fires it will smoke like hell so don't be scared after it does. A quart of oil in each rotor housing should do. After i got the engine running a couple of time i changed the leading plugs to new and voila that made the trick.

I have another problem now. When i start the engine it initially runs fine . Good idle and no excessive smoke. However after a few minutes just as soon as the radiator fans switch on a huge cloud of black smoke starts coming out and the engine starts to idle really fast. Any idea what could be going on ?

News flash do not put a quart of anything in the rotor housings. Maybe 3/4 oz!

Damn i meant 3 to 4 oz! Sorry.

so i have to put in about 3 to 4 oz of oil through the leading plug holes or lower plug holes and start the car??? Because according to the site up top they said the lower plug holes and can this foul the spark plugs at all? I just bought two pairs of brand new injectors and after trying to start the car, when i took it out it looks like theres a ton of grease all over then spark plugs now are these spark plugs bad then???


Is the MAP sensor the one that said boost sensor on it??? because i already plug that in and also a little vacuum hose to the back of the TPS so is this the one???

But earlier i tried to take the EGI out and turn the engine over so that it could build up some compression like the site at the top said but didn't add oil to the plug holes. After that i tried to start the engine it is still not staring.


This is damn frustrating ****!!! does anyone live near by that could help me i'll pay you well so please if you would like to help give me a call thanks

First you need to check for spark, fuel and compression....those are the three key elements that you need to confirm. If compression is low because of a recent rebuild and the car has a manual transmission, try to bump start it by having an assistant pull you with tow rope. This must come AFTER you've confirmed that everything was assembled/connected correctly.

Sounds like you need to set the load idle. Follow the procedure in the manual for setting up the TB for correct idle with electrical loads and no load. Everyone still thinks you are unable to get the car running at all.

Hey guys finally got this thing started and man it was a simple freakin mistake


I got everything in right, fuel line, pump, electrical and all., The only thing i didn't get right was the sensor on the fuel rail, the fuel sensor and the water sensor since they uses the same plugs for both just different color, brown and green. But what happened is that the one on the fuel line broke and i guess the previous owner uses the water temp plug for it so they're both green. And at the time of plugging everything back in it was a guess and i totally forgot about that, so that's what happened and why it didn't start but after switching those two it started right up.....Yey :-)
