Hello, guys. At first,sorry for my english,Im from central europe.
I have a strange problem with my engine in my car (Olds Bravada)- wont start,
but I have a new sparks and wires,rotor and cap its too ok, new fuel pump and sending unit, new relays, all connectors ,and wires its ok, no trouble codes, fuel pressure its 62 psi and stay on (no leaks ,or pressure regulator), new intake manifold gasket.. I do a video, you can hear a "clicking " from a Intake manifold tuning valve relay ( ? its ok??)..
Thanks for the help !!!!!

The E.G.R. Valve could be stuck open by having carbon build up. Once a year I take mine off the check/clean. It's located right under your intake with a wire harness and two 10mm bolts. Take off an inspect an clean with carb stray. Make sure the postal is moving freely. It's about a 15 minute job.

 

Hello, Thanks.
EGR its clean, and looks good.The "movable part" of egr its stay in "hole" when I pull it down,thats right??.. Today I try next second pump, and coil.. now I have spark, fuel injectors working, pressure regulator too..
It makes me nervous..

 

*Update*
fuel pressure now do this :

your intake is really clean on the regulator side, should be black.

 

It was cleaned ..

 

Yes the egr petal should move up an down freely. If it's stuck it won't start the engine. With the intake plutuem off and egr valve off you can clean the holes where the egr is. Have you replaced your fuel filter. It's underneath on drivers side in middle of wheel base. I'm not sure about that clicking noise your getting.

 

News : Egr move freely.. But I have care about fuel line/pump..

 

Wow. I'm stumped on this problem your having with not firing up. The ignition control module might be your problem it's located under you distributor cap that has two mounting screws an a wire harness. It could be your problem. I take it you have checked your fuses under dash by your parking break pedal. It has too be something electrical causing this.

 

Any luck yet with the motor starting? I'll do some research for you. I enjoy helping people solve their problemsm.
