I'm having a problem with my 87 TII. I've just got done working on it. I did alot of things to it including rats nest removal, TID mod, walbro fuel pump, fuel pump rewire, new injectors, full 3" exhaust, etc.
Now this is what happens when I try to Start her up. I can crank all day and won't hear a single triangle wall light up. So I tried holding it at WOT for a few seconds while I crank it and let go, then engine starts for 1-3 seconds and stalls. If i try to rev it up after it starts it dies immediatelly. I've checked the pump and it's getting voltage. What could be possible cause of such behavior. I've worked really hard since I bought this car and it breaks my heart seeing her not running after all this hard work. Please help.

 

What's the voltage at the fuel pump while this is happening? If you jumper the fuel pump test connector in the engine bay does it run?

 

wat kind of injectors did u put in. u sure they are the correct impedence..if u just put in larger secondaries this would not matter though at idle...check your rewire...thats where i would start

 

it's getting full voltage to the pump while I'm starting it and when it starts up for couple of seconds. Could it be the TPS? I'll start troubleshooting tomorow. The injectors are low impedence from www.injector.com
Hopefully I'll figure it out

 

Btw,

after removing rats nest, is this how your fuel setup should look like? I'm thinking I'm not getting enough fuel due to fpr or something...

 

No, that would be backwards, and would explain why the engine doesn't run. The supply line (from the filter) goes to the primary rail, the return line goes to the secondary rail.

 

Compression test?

hmm that would explain it

 

That what I thought NZ,
man you always come around with some helpfull advice. I should fly to auckland just so that you can punch me in the face for being so rotary illiterate.

Put fuel lines backward, what a tard (puts on a hat)....

 

Boom, and it fired right up.

Car started up, idles nicelly at around 2.5K rpm and drops to 1.2. Then it jumps like between 1.2 and 1.5 k like brrruuuuuuuuup brrrrrruuuuuup bruuuuuuuuuuup. Sounds like a freaking top fuel drag car idle. And it did exactly the same before I did all that work to it. Also I experience little stuterness and light throttle.

So help me out here guys one more time. I'm thinking it's either TPS, BAC, or my ecu.

I've checked my TPS ohms and they are between 1.1 and 4.4 ohms. Only thing is I can't find the green three plug connector to check it with LED lights.

 

Try unplugging the TPS and see if idle changes, if so your TPS is bad!

 

ok, I'll do that tomorrow
