Zayed And Others..
I have a problem that's been there for months now.
- turn car on, turns on but right away like 2 seconds it turns right off.
Turn it on again and it stays on.
- If I turn key on to let the fuel pump engage, the car will turn on each and every time and it will stay on.
- After its on I drive, I than park and turn it off. I wait like 2-3 minutes and I go to the fuel injector port in the front of the engine. I push the little nipple and no gas comes out at all. IS THIS NORMAL?
Seems like I'm loosing fuel pressure right? If yes what should I check?
Thanks for any suggestions.

Hi mate,
Yes, it's looks like air/fuel issue, but not so sure..!,
did you try to diagnose the car, it will help a lot to see if all Electronics/sensors reading properly,,
also prefer to pull-out airbox & see all hoses/fuel rail/ injectors, if no leaks around them, no any connectors been loose..

Thanks Zayed.
I went and checked air hoses and no leaks at all. I checked the fuel lines and fuel injectors and no leaks.
I still have to check fuel lines from engine to fuel pump when I get a chance...
Do you think maybe the fuel pump or fuel regular going bad?

MAF could interrupt the whole air/fuel system, in sme cases; ECU memory didn't catch that..!!

Or Ebay. The part number is listed on the German Star site so you can search for other sources using that.

It's good point, i didn't know U.S version got a Black relay with flat pins,
your black relay #: 002 542 13 19, isn't..?
*Bosch create that fuse at the top of relay (as safety) to avoiding damaging relay line circuit,,
which fuel pump you ordered..?

Btw, I installed another intake manifold that I cleaned up and had ready. No leaks and works great BUT the thing is noisy? My old one was not like this, any ideas why?
I would put the old one back but although it's not noisy it does not perform like the noisy one? Both were cleaned the same way...

Ok, thanks zayed. Bosch was $100.00 more. So far the pump is working very well. Weird thing is with the old bosch I could not hear the pump pushing fuel. This new one I can hear the fuel or pump working. Don't know if that good or not.
Any thoughts on the noisy intake manifold?

Zayed, I can't find any specs on the pump. Here's a link to the one I bought.
Also, it's not a whistle sound, more like a hollow sound. Can't explain I will upload a sound clip later on.
