So yesterday I finally finished up with my car. After about 3 months of waiting for parts and working on the car day in and day out I finally got it together. After my engine blew I installed one new rotor housing and two new rotors with a street port and 3mm apex seals. I also replaced the turbos and upgraded them to the BNR stage 2 unit. I have ALL the emission equipment removed, including the solenoids, air pump..., and got the block off plate kit. I also upgraded to 1300cc injectors and put in a high flow walbro fuel pump. Other mods on my car include, greddy FMIC, greddy elbow, type-s BOV, DP, MD, dual tip N1, Power FC, ACT SS clutch, Indigo under drive pulleys, and a Bunch of the other necessary things. So I went to go start the car tomorrow and it wont start? When I turn the key the engine makes that "pre-starting" sounds but wont go any further than that. While we were trying to start it I realized a fuel leak coming from right under the engine on the passenger side. Now could this leak be the cause of my car not starting? The car is still getting gas, don't you think it should still start? When looking at the commander the Injection duty shows around 8% and when I turn the key it goes down to about 2%. I'm pretty sure the drop in fuel pressure is the problem. Then when we tried push starting the car it worked, but the idle was very low and just died out after a few seconds.

I'm pretty sure the leak is the cause of my problem, but I'm not an expert on this so that why I'm posting. What do you guys think? What other problems might I run across trying to start the car? I appreciate all replies, Thanks.

Someone...? Please.

"pre-starting sounds"?

You have to be a little more descriptive then that. Is your starter turning? Is your starter solenoid clicking? Is your battery fully charged?

Check all of these.

Also, spray some WD-40 in your spark plug holes; this will help with the initial startup.

Fix your fuel leak before you start your car.

Yes, the started is turning and the battery is fully charged. Ill try the WD-40, but i was planing on using starter fluid, I was going to just spray some in the UIM. Would this help any?

Don't know why it won't start, but after looking at your mods....you have more than three upgrades, yet you didn't upgrade your ECU. The basic rule of thumb is upgrade the ECU if you have mnore than 3 mods, such as 1)greddy FMIC 2) DP 3) dual tip N1

Need I go on?

When adding mods to your Rex, add them one at a time, then if and when something goes wrong, you can easily diagnose the prob.

He has a PFC. He mentioned injector duty cycle on the commander

tomaszjc7

... yeah

Anyway I was looking into the whole problem and pulled dapart a lot of the engine only to discover that I have no idea where this gas is comming from. So I started playing around with the PFC and switch the primary injector level from 850 to 1300, i assume thats what u do when u get the upgraded 1300 cc injectors. Havent tried starting the car yet with this change, but do you think that me putting in the new fuel pump and leaving the old PFC fuel setting the same maybe messed something up? I dunno, ill be looking into this further on satuday.

ejmack1

so you upgraded your primaries to 1300cc from 850cc's?

tomaszjc7

No, no, no... I upgraded the secondaries from 850 to 1300...sorry, But ahh i guess that really doesnt matter cause they dont inject fuel during idle...?? God I hate cars.

Bump...
